In this dissertation a novel alternative system concept for monocular-inertial egomotion and landmark position determination is introduced. It is mainly motivated by an in-depth analysis of the observability and consistency of the classic simultaneous localization and mapping (SLAM) approach, which is based on a world-centric model of an agent and its environment. Within the novel system concept - a body-centric agent and environment model, - a pseudo-world centric motion propagation, - and closed-form initialization procedures are introduced. This approach allows for combining the advantageous observability properties of body-centric modeling and the advantageous motion propagation properties of world-centric modeling. A consistency focused and simulation based evaluation demonstrates the capabilities as well as the limitations of the proposed concept. / In dieser Dissertation wird ein neuartiges, alternatives Systemkonzept für die monokular-inertiale Eigenbewegungs- und Landmarkenpositionserfassung vorgestellt. Dieses Systemkonzept ist maßgeblich motiviert durch eine detaillierte Analyse der Beobachtbarkeits- und Konsistenzeigenschaften des klassischen Simultaneous Localization and Mapping (SLAM), welches auf einer weltzentrischen Modellierung eines Agenten und seiner Umgebung basiert. Innerhalb des neuen Systemkonzeptes werden - eine körperzentrische Modellierung des Agenten und seiner Umgebung, - eine pseudo-weltzentrische Bewegungspropagation, - und geschlossene Initialisierungsprozeduren eingeführt. Dieser Ansatz erlaubt es, die günstigen Beobachtbarkeitseigenschaften körperzentrischer Modellierung und die günstigen Propagationseigenschaften weltzentrischer Modellierung zu kombinieren. Sowohl die Fähigkeiten als auch die Limitierungen dieses Ansatzes werden abschließend mit Hilfe von Simulationen und einem starken Fokus auf Schätzkonsistenz demonstriert.

Fotogrammetri är en viktig metod för att skapa 3D-representationer av terräng och strukturer, men utmaningar kvarstår när det gäller noggrannheten på grund av faktorer som bildkvalitet, kamerakalibrering och positionsdata. Användningen av drönare för byggnadsdetaljmätning möjliggör snabb och kostnadseffektiv datainsamling, men noggrannheten kan påverkas av bildkvalitet och skuggning. Avhandlingen syftar till att jämföra noggrannheten och kvaliteten hos punktmoln genererade med två olika tekniker: terrester laserskanning (TLS) och struktur-från-rörelse (SfM) fotogrammetri med drönare. För att testa båda metodernas osäkerhet och noggrannhet vid detaljmätning av bostäder. Genom att utföra mätningar på en villa har data samlats in med både TLS och drönare utrustade med 48 MP kamera, samt georeferering med markstöd (GCP). SfM-punktmoln bearbetades med Agisoft Metashape. Jämförelser gjordes mellan SfM- och TLS-punktmoln avseende täckning, lägesskillnad och lägesosäkerhet. Genom att följa riktlinjer från HMK - Terrester Laserskanning och tillämpa HMK Standardnivå 3 säkerställs hög noggrannhet i mätningarna. Kontroll av lägesosäkerhet av båda punktmolnen resulterade i en lägesosäkerhet som understeg toleranser satta enligt HMK - Terrester laserskanner Standardnivå 3.  Kontrollen av lägesosäkerheten visade att kvadratiska medelfelet(RMSE) i plan och höjd var 0.011m respektive 0.007m för TLS-punktmolnet, och 0.02m respektive 0.015m för drönar-SfM-punktmolnet, vilket låg under toleransen enligt HMK- Terrester Detaljmätning 2021. Resultaten tyder på att Structure-from-Motion fotogrammetri med drönare kan generera punktmoln med god detaljrikedom, inte lika noggrann som med terrester laserskanner på sin lägsta inställning. TLS uppvisade mindre osäkerhet enligt kontrollen av lägesosäkerhet, ungefär en halvering av RMSE i både plan och höjd. I studien framgick det att TLS presterar sämre vid svåråtkomliga ytor med skymd sikt och ogynnsamma infallsvinklar, där effekten blir en lägre punkttäthet för punktmolnet. Vid gynnsamma förhållanden erbjuder TLS en högre noggrannhet och detaljnivå jämfört med SfM punktmoln. Enligt M3C2 punktmoln analys, med TLS punktmolnet som referens, antydde det att SfM punktmolnet genererade största felen vid takfot samt vid buskage. De större felen vid takfot tyder på att SfM presterar sämre gällande detaljnivå och fel vid buskageområdet varierar inte från det som dokumenterats om fotogrammetriska fel vid mappning av vegetation. SfM kan utföra en effektiv datainsamling för större samt svåråtkomliga ytor men kräver lång bearbetningstid med diverse hjälpmedel för att uppnå hög noggrannhet. TLS kräver istället en lång datainsamlingsprocess men kan generera ett detaljerat och noggrant punktmoln direkt utan långa bearbetningsprocesser. Val av metod styrs därmed baserat på specifika projektkrav. Långsiktiga implikationer inkluderar förbättrad effektivitet och säkerhet inom bygg- och anläggningsprojekt, samt potentialen för kostnadsbesparingar och mer detaljerade inspektioner. / Photogrammetry is a crucial method for creating 3D representations of terrain and structures, yet challenges remain regarding accuracy due to factors such as image quality, camera calibration, and positional data. The use of drones for building detail measurements enables rapid and cost-effective data collection, but accuracy can be affected by image quality and shading. This thesis aims to compare the accuracy and quality of point clouds generated using two different techniques: terrestrial laser scanning (TLS) and Structure-from-Motion (SfM) photogrammetry with drones. The objective is to test the uncertainty and accuracy of both methods in residential surveying. Data collection was performed on a villa using both TLS and a drone equipped with a 48 MP camera, along with georeferencing with ground control points (GCP). SfM point clouds were processed with Agisoft Metashape. Comparisons were made between SfM and TLS point clouds in terms of coverage, positional difference, and positional uncertainty. By following guidelines from HMK - Terrester laserskanning 2021 and applying HMK Standard Level 3, high measurement accuracy was ensured. Positional uncertainty checks of both point clouds resulted in positional uncertainty within tolerances set by HMK - Terrestrial Laser Scanning Standard Level 3. The positional uncertainty, with a sample of 41 points showed that the root mean square error (RMSE) in plane and height was 0.011m and 0.007m respectively for the TLS point cloud, and 0.02m and 0.015m for the drone-SfM point cloud, both within the tolerance according to HMK - Terrestrial Detail Measurement 2021. The results suggest that Structure-from-Motion photogrammetry with drones can generate point clouds with good detail, although not as accurate as terrestrial laser scanning at its lowest setting. TLS showed less uncertainty according to the positional uncertainty check, with approximately half the RMSE in both plan and height. The study found that TLS performs worse on difficult-to-access surfaces with obstructed views and unfavorable angles, resulting in lower point cloud density. Under favorable conditions, TLS offers higher accuracy and detail compared to SfM point clouds. According to M3C2 point cloud analysis, using the TLS point cloud as a reference, SfM point clouds showed the largest errors at eaves and shrubbery. The larger errors at eaves indicate that SfM performs worse in terms of detail level, and errors in the shrubbery area are consistent with documented photogrammetric errors in vegetation mapping. SfM can effectively collect data for larger and difficult-to-access areas but requires extensive processing time with various aids to achieve high accuracy. Conversely, TLS requires a long data collection process but can generate a detailed and accurate point cloud directly without lengthy processing. The choice of method thus depends on specific project requirements. Long-term implications include improved efficiency and safety in construction and infrastructure projects, as well as potential cost savings and more detailed inspections.

Recently, sensors such as radars and cameras have been widely used in automotives, especially in Advanced Driver-Assistance Systems (ADAS), to collect information about the vehicle's surroundings. Stereo cameras are very popular as they could be used passively to construct a 3D representation of the scene in front of the car. This allowed the development of several ADAS algorithms that need 3D information to perform their tasks. One interesting application is Road Surface Preview (RSP) where the task is to estimate the road height along the future path of the vehicle. An active suspension control unit can then use this information to regulate the suspension, improving driving comfort, extending the durabilitiy of the vehicle and warning the driver about potential risks on the road surface. Stereo cameras have been successfully used in RSP and have demonstrated very good performance. However, the main disadvantages of stereo cameras are their high production cost and high power consumption. This limits installing several ADAS features in economy-class vehicles. A less expensive alternative are monocular cameras which have a significantly lower cost and power consumption. Therefore, this thesis investigates the possibility of solving the Road Surface Preview task using a monocular camera. We try two different approaches: structure-from-motion and Convolutional Neural Networks.The proposed methods are evaluated against the stereo-based system. Experiments show that both structure-from-motion and CNNs have a good potential for solving the problem, but they are not yet reliable enough to be a complete solution to the RSP task and be used in an active suspension control unit.

<p>Simultaneous localization and mapping (SLAM) is a general device localization technique that uses realtime sensor measurements to develop a virtualization of the sensor's environment while also using this growing virtualization to determine the position and orientation of the sensor. This is useful for augmented reality (AR), in which a user looks through a head-mounted display (HMD) or viewfinder to see virtual components integrated into the real world. Visual SLAM (i.e., SLAM in which the sensor is an optical camera) is used in AR to determine the exact device/headset movement so that the virtual components can be accurately redrawn to the screen, matching the perceived motion of the world around the user as the user moves the device/headset. However, many potential AR applications may need access to more than device localization data in order to be useful; they may need to leverage environment data as well. Additionally, most SLAM solutions make the naive assumption that the environment surrounding the system is completely static (non-moving). Given these circumstances, it is clear that AR may benefit substantially from utilizing a SLAM solution that detects objects that move in the scene and ultimately provides localization data for each of these objects. This problem is known as the dynamic SLAM problem. Current attempts to address the dynamic SLAM problem often use machine learning to develop models that identify the parts of the camera image that belong to one of many classes of potentially-moving objects. The limitation with these approaches is that it is impractical to train models to identify every possible object that moves; additionally, some potentially-moving objects may be static in the scene, which these approaches often do not account for. Some other attempts to address the dynamic SLAM problem also localize the moving objects they detect, but these systems almost always rely on depth sensors or stereo camera configurations, which have significant limitations in real-world use cases. This dissertation presents a novel approach for registering and localizing unknown moving objects in the context of markerless, monocular, keyframe-based SLAM with no required prior information about object structure, appearance, or existence. This work also details a novel deep learning solution for determining SLAM map initialization suitability in structure-from-motion-based initialization approaches. This dissertation goes on to validate these approaches by implementing them in a markerless, monocular SLAM system called LUMO-SLAM, which is built from the ground up to demonstrate this approach to unknown moving object registration and localization. Results are collected for the LUMO-SLAM system, which address the accuracy of its camera localization estimates, the accuracy of its moving object localization estimates, and the consistency with which it registers moving objects in the scene. These results show that this solution to the dynamic SLAM problem, though it does not act as a practical solution for all use cases, has an ability to accurately register and localize unknown moving objects in such a way that makes it useful for some applications of AR without thwarting the system's ability to also perform accurate camera localization.</p>

The concept of Sustainable Forest Management (SFM) has been promoted in the past few decades all over the world. Non-industrial private forest (NIPF) owners play an important role in that aspect in the U.S. because of their number (about 16 millions), the size of forest land under their control (about half of all forest land in the continental US), and the dynamism of their population (increasing number of new owners). This study sought to better understand how NIPF owners come to a decision for adoption (or non-adoption) of SFM practices. We developed a theoretical model combining four theories (the Value-Belief-Norm theory, the Theory of Planned Behavior, the Elaboration Likelihood Model, and the Innovation-Diffusion Process) to explain NIPF's decision making. Using multivariate analyses, we determined which elements of the developed theoretical model were significant in explaining adoption of eight groups of practices. Overall, some of the most significant predictors of adoption we identified were technical assistance, motivations for owning land and the use of a written management plan. Particular attention was also directed toward the eventual relationship between education and adoption of SFM practices and it was found that NIPF owners who attended educational programs tended to be likely adopters compared to those who did not attend any educational program. Since SFM was not limited to the US, we also analyzed the concept of SFM with the same goals as in the US, but under a completely different context (socio-cultural, economic and ecologic) in Africa, through the community-based natural resource management (CBNRM) system. We used four case studies and focused on criteria such as participation, equity (both procedural and distributive, power devolution, trust, etc) to analyze how CBNRM works on the field, what lessons to take from the cases to better ensure the goal of sustainability of the resources. / Ph.

Im ersten Teil der Arbeit werden Graphen sowie von Monolagen von auf Nanometer großen Graphenen basierenden Hexa-peri(Dodekyl)-Hexabenzocoronen-Molekülen (HBC-C12), adsorbiert auf Graphen, mit Rastertunnelmikroskopie und –spektroskopie an der Fest-Flüssig-Grenzfläche untersucht. Nanographen-Moleküle selbstaggregieren epitaktisch zu hochgeordneten Monolagen. Die Einheitszellen der Moleküllagen auf Monolage Graphen, Bilage Graphen und auf Graphit sind ununterscheidbar. Die Strukturen der Moleküllagen auf gewellten und flachen Teilen des Graphens stimmen überein. Strom-Spannungs-Kennlinien an Nanographen auf Graphen und auf Graphit weisen auf sehr ähnliche elektronische Eigenschaften hin. Zusammengefasst sind strukturelle sowie elektronische Eigenschaften der Nanographenlage homogen, stabil und definiert. Graphen erweist sich als bestens als Substrat und gleichzeitig als Elektrode für hochgeordnete Lagen von Nanographen-Molekülen geeignet. Im zweiten Teil der Arbeit wird Graphen mit der Sonde eines Rasterkraftmikroskops im Kontaktmodus mechanisch manipuliert. Es wird gezeigt, dass Graphen in nur einem Manipulationsschritt zu Streifen und Spalt geschnitten werden kann. Dieses Verhalten wird mit einem klassischen Modell des Biegens theoretisch erklärt. Das Schnittverhalten liegt in der 2-Dimensionalität des Graphens sowie in dessen Faltbarkeit auf Grund hinreichender Elastizität begründet. Durch mechanische Manipulation mit der Sonde des Rasterkraftmikroskops im Kontaktmodus unter atmosphärischen Bedingungen wird eine Flüssigkeitsschicht zwischen Graphen und dem Siliziumdioxidsubstrat nachgewiesen, welche eine mögliche Erklärung des stark kraftabhängigen Materialkontrasts zwischen Graphen und Siliziumdioxid im Amplitudenmodulationsmodus des Rasterkraftmikroskops darstellt. Weiter wird gezeigt, dass das Falten des Graphens durch mechanische Manipulation eine geeignete Methode zur Herstellung nicht epitaktisch aufeinander gestapelter Graphene darstellt. / In the first part of the thesis graphene as well as monolayers of hexa-peri(dodecyl)-hexabenzocoronene molecules (HBC-C12) based on nanometer sized graphenes adsorbed on graphene is investigated by scanning tunnelling microscopy and tunneling spectroscopy at the solid-liquid interface. The nanographene molecules self-assemble on graphene epitaxially to form highly ordered monolayers. The unit cells of the molecular layers on monolayer graphene, bilayer graphene and on graphite appear identical. The structures of the molecular layers occur equal on corrugated and on flat parts of graphene. Current-voltage-characteristics show that the electronic properties of nanographene on graphene and on graphite are very similar. Summarized, structural as well as electronic properties of the nanographene layer are homogeneous, stable and defined. Graphene proves to be excellently qualified for simultaneously being substrate as well as electrode for highly ordered layers of nanographene based molecules. In the second part of the thesis graphene is mechanically manipulated in air in contact mode of a scanning force microscope. It is shown that a single manipulation process can lead to a stripe cut out of graphene. This behaviour is theoretically explained by a classical bending model. The cutting behavior originates from the 2-dimensionality of graphene and its folding ability because of sufficient elasticity. A liquid layer between graphene and the silicon dioxide substrate is verified by mechanical manipulation in contact mode of a scanning force microscope. Hence a possible explanation could be found for the strongly force dependent material contrast between graphene and silicon dioxide in amplitude modulation mode of the scanning force microscope. Further, it is demonstrated that folding graphene by mechanical manipulation is a proper method for the production of graphene stacked on each other non-epitaxially.

This thesis describes methods of reconstruction of 3D scenes from photographs and videos using the Structure from motion approach. A new software capable of automatic reconstruction of point clouds and polygonal models from common images and videos was implemented based on these methods. The software uses variety of existing and custom solutions and clearly links them into one easily executable application. The reconstruction consists of feature point detection, pairwise matching, Bundle adjustment, stereoscopic algorithms and polygon model creation from point cloud using PCL library. Program is based on Bundler and PMVS. Poisson surface reconstruction algorithm, as well as simple triangulation and own reconstruction method based on plane segmentation were used for polygonal model creation.

This project is an examination of the possibility of using existing software to develop Virtual Reality (VR) software that includes key aspects of objects in a user’s surroundings into a virtual environment, producing Augmented Virtuality (AV). A defining limitation is the requirement that the software be consumer-accessible, meaning it needs run on a common smartphone with no additional equipment. Two related AV concepts were considered: shape reconstruction and positional tracking. Two categories of techniques were considered for taking the measurements of reality necessary to achieve those AV concepts using only a monocular RGB camera as sensor: monocular visual SLAM (mvSLAM) and Structure from Motion (SfM). Two lists of requirements were constructed, formalising the notions of AV and consumer-accessibility. A search process was then conducted, where existing software packages were evaluated for their suitability to be included in a piece of software fulfilling all requirements. The evaluations of SfM systems were made in combination with Multi-View Stereo (MVS) systems – a necessary complement for achieving visible shape reconstruction using a system that outputs point clouds. After thoroughly evaluating a variety of software, it was concluded that consumer-accessible AV can not currently be achieved by combining existing packages, due to several issues. While future hardware performance increases and new software implementations would solve complexity and availability issues, some inaccuracy and usability issues are inherent to the limitation of using a monocular camera. / Detta projekt är en undersökning av möjligheten att använda befintlig programvara till att utveckla Virtual Reality (VR)-programvara som infogar framstående aspekter av objekt från en användares omgivning in i en virtuell miljö och därmed skapar Augmented Virtuality (AV). En definierande begränsning är kravet på att programvaran skall vara konsumenttillgänglig, vilket innebär att den behöver kunna köras på en vanlig smartphone utan extra utrustning. Två besläktade AV-koncept beaktades: formrekonstruktion och positionsspårning. Två kategorier av tekniker togs i beaktande, vilka kunde användas för att göra de uppmätningar av verkligheten som var nödvändiga för att uppnå de tänkta AV-koncepten med hjälp av endast en monokulär RGB-kamera som sensor: monocular visual SLAM (mvSLAM) och Structure from Motion (SfM). Två listor med kriterier konstruerades, vilka formaliserade begreppen AV och konsumenttillgänglighet. En sökprocess utfördes sedan, där befintliga programvarupaket utvärderades för sin lämplighet att inkluderas i en programvara som uppfyllde alla kriterier. Utvärderingarna av SfM-system gjordes i kombination med Multi-View Stereo (MVS)-system – ett nödvändigt komplement för att uppnå synlig formrekonstruktion med ett system vars utdata är punktmoln. Efter att noggrant ha utvärderat en mängd programvara var slutsatsen att konsumenttillgänglig AV inte för närvarande kan uppnås genom att kombinera befintliga programvarupaket, på grund av ett antal olika problem. Medan framtida prestandaökningar hos maskinvara och nya programvarutillämpningar skulle lösa problem med komplexitet och tillgänglighet, är vissa problem med tillförlitlighet och användbarhet inneboende hos begränsningen till att använda en monokulär kamera.

[ES] En la civilización de la antigua Roma, tres de los aspectos más importantes de la vida cotidiana estaban vinculados a la arquitectura: las termas, los acueductos y las tumbas. Esta investigación propone el estudio de la integración de sistemas avanzados para la documentación, gestión y valorización del patrimonio arquitectónico funerario de la Vía Latina y la Vía Appia Antica, en estrecha relación con el tema del Paisaje Cultural. De hecho, el Parque de las Tumbas Latinas alberga uno de los complejos funerarios más importantes, que en la actualidad conserva inalterado el aspecto tradicional del antiguo paisaje romano. A lo largo de una vía empedrada, como todas las vías consulares, la Vía Latina (al igual que la Vía Appia Antica), que, como recuerda Livio, conectaba en su día las ciudades de Roma con Capua, mantiene aún el "congelado" trazado urbano/paisajístico antiguo. El tema de la carretera y el sistema de infraestructuras es, de hecho, una manifestación de una necesidad humana fundamental, la del movimiento, y refleja la historia de toda la humanidad en su evolución. En la actualidad, a lo largo de un tramo de unos 450 metros, hay numerosas tumbas de diversos tipos construidas entre la época republicana y la Alta Edad Media. Este estudio no se centra exclusivamente en el patrimonio arquitectónico de las antiguas tumbas, sino que también pretende realizar un análisis urbanístico de la red de infraestructuras que conecta el yacimiento arqueológico con el centro histórico de Roma y de la relación que se establece entre los restos antiguos y el paisaje tradicional del Lacio en el que se contextualizan: el Ager Romanus. Este aspecto es muy importante para toda la propuesta de investigación, ya que es parte integrante de todo el análisis. De hecho, la sinergia derivada de la relación entre estos componentes, que convergen en su forma esencial, es: "una síntesis de los elementos visuales que insisten en un espacio incluido en un único círculo de horizonte" (Biasutti, 1962). En el caso concreto, el paisaje de la Vía Latina y la Vía Appia Antica es una realidad muy compleja que consiste en la interrelación entre las ruinas (Tumbas), los elementos bióticos, el centro histórico y la red urbana periférica compuesta por las antiguas vías que han de convivir con la continua expansión de los ejes contemporáneos. Por lo tanto, este sistema polifacético del Ager Romanus y del sitio cultural Vía Latina/Appia Antica es comparable a una estructura viva y dinámica y, como tal, debe ser analizada. El último aspecto clave que la investigación quiere abordar es la catalogación. De hecho, los sitios y monumentos históricos no se pueden mantener sólo mediante su uso y utilización pasiva, sino activando todas las operaciones de protección y conservación mediante intervenciones directas (mantenimiento/restauración) e indirectas, como la catalogación constante de las obras históricas y la consiguiente "catalogación dinámica". En el caso de las tumbas de la Vía Latina y de la Vía Appia Antica, este procedimiento está actualmente incompleto: uno de los objetivos de la investigación será la creación de un archivo/base de datos que permita el seguimiento constante de las tumbas antiguas. Para diseñar una herramienta de protección y gestión tan "potente", será necesario utilizar las técnicas de levantamiento arquitectónico más avanzadas que se utilizan actualmente (como el escaneo láser y la fotogrametría, junto con programas informáticos de análisis específicos), acompañadas de un estudio en profundidad de las técnicas de construcción antiguas. / [CA] En la civilització de l'antiga Roma, tres dels aspectes més importants de la vida quotidiana estaven vinculats a l'arquitectura: les termes, els aqüeductes i les tombes.

De fet, el Parc de les Tombes Latines alberga un dels complexos funeraris més importants, que en l'actualitat conserva inalterat l'aspecte tradicional de l'antic paisatge romà. Al llarg d'una via empedrada, com totes les vies consulars, la Via Latina (igual que la Via Appia Antica), que, com recorda Livio, connectava al seu dia les ciutats de Roma amb Capua, manté encara el congelado traçat urbano/paisajístico antic. El tema de la carretera i el sistema d'infraestructures és, de fet, una manifestació d'una necessitat humana fonamental, la del moviment, i reflectix la història de tota la humanitat en la seua evolució.

Este estudi no se centra exclusivament en el patrimoni arquitectònic de les antigues tombes, sinó que també pretén realitzar una anàlisi urbanística de la xarxa d'infraestructures que connecta el jaciment arqueològic amb el centre històric de Roma i de la relació que s'establix entre les restes antigues i el paisatge tradicional del Llis en què es contextualitzen: l'Ager Romanus. Este aspecte és molt important per a tota la proposta d'investigació, ja que és part integrant de tota l'anàlisi. De fet, la sinergia derivada de la relació entre estos components, que convergixen en la seua forma essencial, és "una síntesi dels elements visuals que insistixen en un espai inclòs en un únic cercle d'horizonte" (Biasutti, 1962). En el cas concret, el paisatge de la Via Latina i la Via Appia Antica és una realitat molt complexa que consistix en la interrelació entre les ruïnes (Tombes), els elements biòtics, el centre històric i la xarxa urbana perifèrica composta per les antigues vies que han de conviure amb la contínua expansió dels eixos contemporanis. Per tant, este sistema polifacètic de l'Ager Romanus i del lloc cultural Via Latina/Appia Antica és comparable a una estructura viva i dinàmica i, com a tal, ha de ser analitzada. L'últim aspecte clau que la investigació vol abordar és la catalogació.

En el cas de les tombes de la Via Latina i de la Via Appia Antica, este procediment està actualment incomplet: un dels objectius de la investigació serà la creació d'un archivo/base de dades que permeta el seguiment constant de les tombes antigues. Per a dissenyar una ferramenta de protecció i gestió tan "potente" serà necessari utilitzar les tècniques d'alçament arquitectònic més avançades que s'utilitzen actualment (com l'escaneig làser i la fotogrametria, junt amb programes informàtics d'anàlisis específiques), acompanyades d'un estudi en profunditat de les tècniques de construcció antigues. / [EN] In the civilization of ancient Rome, three of the most important aspects of daily life were linked to architecture: the Baths, the Aqueducts and the Tombs. This research proposes the study of the integration of advanced systems for the documentation, management and valorization of the architectural funerary heritage of the Via Latina and Via Appia Antica, in close relation to the theme of Cultural Landscape. In fact, the Park of the Latin Tombs is home to one of the most important funerary complexes, which currently preserves the traditional appearance of the ancient Roman landscape unchanged. Along a cobbled road, like all consular roads, the Via Latina (as well as the Via Appia Antica), which, as recalled by Livio, once connected the cities of Rome with Capua, still maintains the "frozen" ancient urban/landscape layout. The theme of the road and the infrastructure system is, in fact, a manifestation of a fundamental human need, that of movement, and reflects the history of all humanity in its evolution. Today, along a stretch of about 450 meters, there are numerous tombs of various types built between the Republican Age and the early Middle Ages. This study does not focus exclusively on the architectural heritage of the ancient tombs, but also aims at an urban analysis of the infrastructural network connecting the archaeological site to the historical center of Rome and of the relationship established between the ancient remains and the traditional landscape of Lazio in which they are contextualized: the Ager Romanus. This aspect is very important for the entire research proposal, as it is an integral part of the entire analysis. In fact, the synergy derived from the relationship between these components, which converge in their essential form, is: "a synthesis of the visual elements that insist on a space included in a single circle of horizon" (Biasutti, 1962). In the specific case, the landscape of the Via Latina and the Via Appia Antica is a very complex reality that consists in the interrelation between the ruins (Tombs), the biotic elements, the historical center and the peripheral urban network composed by the ancient roads that have to coexist with the continuous expansion of the contemporary axes. Therefore, this multifaceted system of the Ager Romanus and the Via Latina/Appia Antica cultural site is comparable to a living and dynamic structure and, as such, must be analyzed. The last key aspect that the research wants to address is cataloguing. In fact, historical sites and monuments cannot be maintained only by using them and using them passively, but by activating all the operations of protection and conservation through direct interventions (maintenance/restoration) and indirect ones such as the constant cataloguing of historical works and the consequent "dynamic cataloguing". For the Tombs of the Via Latina and the Via Appia Antica this procedure is currently incomplete: one of the objectives of the research will be the creation of a file/database that will allow the constant monitoring of the ancient Tombs. In order to design such a 'powerful' protection and management tool, it will be necessary to use the most advanced architectural survey techniques currently in use (such as laser scanning and photogrammetry, in conjunction with specific analysis software) accompanied by an in-depth study of ancient construction techniques. / Rinaldi, S.
