In den letzten Jahren kommen immer mehr nicht perspektivische Kamerasysteme beim maschinellen Sehen zur Anwendung, die vor allem ein deutlich erweitertes Blickfeld bieten. Das klassische perspektivische Abbildungsmodell lässt sich hier häufig nicht mehr erfolgreich anwenden. In dieser Arbeit wird ein generisches Abbildungsmodell vorgestellt, welches übliche Kamerasysteme akkurat modellieren kann. Solche Kamerasysteme schließen insbesondere klassische perspektivische Systeme, aber auch Fischaugen- und Spiegellinsen-Kamerasysteme ein. Die Nutzung eines einheitlichen Abbildungsmodells ermöglicht schließlich eine einfache Verwendung und Kalibrierung von heterogenen Stereokamerasystemen, also einer Kombination von unterschiedlichen Kameratypen, die vorteilhafte Eigenschaften gegenüber klassischen Stereosystemen bieten. Nicht zuletzt trägt die in dieser Arbeit vorgestellte einheitliche Modellierung und Kalibrierung von Mono- und Stereokamerasystemen dazu bei, Fehler durch falschen Umgang oder falsche Wahl von Methoden der Modellierung oder Kalibrierung zu vermeiden und den Kamerakalibrierprozess insgesamt zu vereinfachen. In dieser Arbeit wurden verschiedene Ansätze der Modellierung untersucht und evaluiert. Es wurde eine generische Modellierung vorgeschlagen, die die untersuchten spezifischen Abbildungsmodelle vollständig ersetzen kann. Für die Kalibrierung nicht linearer Abbildungsmodelle wurde eine einheitliche Methode zur Startwertbestimmung vorgeschlagen und evaluiert. Die Genauigkeit der Kalibrierung mittels einheitlicher Methoden wurde anhand diverser realer Kamerasysteme untersucht und bewertet. Es konnte gezeigt werden, dass die dabei auftretenden Fehler deutlich im Subpixelbereich liegen. Durch Erweiterung des klassischen Konzepts der Epipolargeometrie um die generische Abbildungsmodellierung konnten schließlich heterogene Stereokamerasysteme kalibriert und genaue Stereomodelle abgeleitet werden. / The application of perspective camera systems in photogrammetry and computer vision is state of the art. In recent years non-perspective and especially omnidirectional camera systems have increasingly been used in close-range photogrammetry tasks. In general, the perspective camera model, i.e. pinhole model, cannot be applied when using non-perspective camera systems. However, several camera models for different omnidirectional camera systems are proposed in literature. Using different types of cameras in a heterogeneous camera system may lead to an advantageous combination. The advantages of different camera systems, e.g. field of view and resolution, result in a new enhanced camera system. If these different kinds of cameras can be modeled, using a unified camera model, the total calibration process can be simplified. Sometimes it is not possible to give the specific camera model in advance. In these cases a generic approach is helpful too. Furthermore, a simple stereo reconstruction becomes possible when using a fisheye and a perspective camera for example. In this work camera models for perspective, wide-angle and omnidirectional camera systems were evaluated. A generic camera model were introduced that fully substitutes specific camera models. The crucial initialization of the model''s parameters is conducted using a new generic method that is independent of the particular camera system. The accuracy of this generic camera calibration approach is validated by the calibration of a dozen of real camera systems up to subpixel accuracy. Finally, it has been shown that a unified method of modeling, parameter approximation and calibration of interior and exterior orientation can be applied to a generic stereo system to derive precise 3D object data.

Auf dem Luftbildsektor vollziehen sich seit einigen Jahren grundsätzliche Veränderungen. Digitale flugzeuggetragene Kamerasysteme und hochauflösende Satellitensysteme bieten neue Potentiale der Datenakquise und -auswertung. Diese digitalen Datensätze werden in absehbarer Zeit das herkömmliche Luftbild ersetzen und Kartographie, Photogrammetrie und Fernerkundung erheblich verändern. Die neue Generation von digitalen Kameras wird zwei zentrale Bereiche der Kartographie einschneidend beeinflussen: Die Orthokartenherstellung und die Kartenaktualisierung. Der Bedarf aktueller Geobasisdaten macht Orthobilder besonders für Geoinformationssysteme interessant. Bisher standen als Basisdaten für Orthobildkarten großer Auflösung (> 1:10 000) lediglich Luftbilder zur Verfügung. Es wird gezeigt, daß die digitalen Daten der neuen Kamerageneration zur Erstellung von Orthobildkarten operationell einsetzbar sind. Durch die automatisierte Prozessierung werden sie den Anforderungen an schnelle aktuelle Kartenprodukte gerecht, mit ihrer hochgenauen Navigation bieten die digitalen Systeme die automatisierte Erstellung geometrisch sehr genauer Datensätze, die mit herkömmlichen Mitteln nur sehr aufwendig erreicht werden könnten. Ein Vergleich mit Luftbildern zeigt und bewertet die Unterschiede beider Aufnahmesysteme. Untersucht wurden Datensätze der digitalen Kamera HRSC-A des DLR Adlershof. Mit der HRSC-A (High Resolution Stereo Camera - Airborne) und der speziell für die Prozessierung dieser Daten entwickelten Software steht den Geoinformationsnutzern erstmals ein operationelles System zur Verfügung, das vollständig digital und vollautomatisch hochauflösende Orthobilddaten produziert. Die Pixelauflösung liegt zwischen 10 und 40 cm (Flughöhe von 2500 bis 10 000 m). Als vorteilhaft für die Analyse erweist sich die gleichzeitige Verfügbarkeit von hochauflösenden panchromatischen und multispektralen Datensätzen, die Verfügbarkeit eines hochauflösenden Geländemodells (x,y: 50 cm bzw. 1m, z: 10 cm) und die hohe Genauigkeit der Datensätze. Die Arbeit diskutiert die Problematik einer automatisierten Auswertung hochauflösender Daten. Diese Datensätze stellen neue Anforderungen an Auswertungsverfahren. Der Detailreichtum erschwert die Interpretation, gröbere räumliche Auflösungen glätten die Komplexität innerhalb heterogener Landnutzungen (besonders in urbanen Gebieten) und erleichtern so eine automatische Interpretation. Es wird gezeigt, daß "klassische" Auswertungsmethoden wie pixelbasierte Klassifizierungen (überwacht oder unüberwacht) zur Auswertung der hochauflösenden Daten nur bedingt geeignet sind. Im Rahmen der Arbeit werden zwei neue Ansätze entwickelt und untersucht, die nicht mehr pixelweise, sondern flächenhaft und objektorientiert arbeiten. Ein per-parcel-Ansatz zeigt gute Ergebnisse bei der Auswertung. Das Verfahren ermittelt zunächst mittels einer unüberwachten Klassifizierung Szenekomponenten in definierten Untereinheiten (parcel), die den Inhalt des Datensatzes repräsentieren. Die klassifizierten Pixel innerhalb der definierten parcel-Einheiten werden anschließend extrahiert und ihr Verhältnis zueinander weiter ausgewertet. Ergebnis ist zunächst die prozentuelle Verteilung der Szenekomponenten in den Einheiten, anschließend werden Zusammenhänge zwischen den vorhandenen Komponenten und der Landoberfläche definiert. Untersucht wurde ferner ein objektorientierter Ansatz, der die Interpretation von Einzelobjekten erlaubt. Hierbei wird das Bild in homogene Objekte segmentiert, die die Grundlage für die weitere Analyse bilden. Der diskutierte Ansatz besteht aus zwei Strategien: Mittels multiskalarer Segmentierung wird der Bilddatensatz zunächst in Einheiten strukturiert, verschiedene Maßstabsebenen sind gleichzeitig verfügbar. Grundidee ist die Schaffung eines hierarchischen Netzes von Bildobjekten. Diese gefundenen Einheiten werden anschließend spektral mittels Nearest Neighbour oder wissensbasiert mittels Fuzzy Logic Operatoren klassifiziert. Der Ansatz zeigt überzeugende Ergebnisse bei einer automatisierten Hauserkennung und der Aktualisierung bestehender Vektordatensätze. Die Einteilung der Bilddaten in Segmente, also zunächst eine Abstrahierung der Information vom Einzelpixel zu größeren semantischen Einheiten und die weitere Bearbeitung dieser Segmente erwies sich als sinnvoll. Es wurde ferner gezeigt, daß für die Analyse in städtischen Räumen die Einbeziehung von Oberflächeninformation unbedingt erforderlich ist. Durch die spektrale Ähnlichkeit von Bildelementen bietet die Einbeziehung des Oberflächenmodells die Möglichkeit, mittels einer zusätzlich bekannten Information über die Höhe der Objekte, diese Klassen zu trennen. / Remote sensing goes through times of fundamental changes. New digital airborne camera systems offer new potentials for data aquisition and interpretation. These data sets will replace aerial photography in the near future and change photogrammetry, cartography and remote sensing. The new camera generation will influence two central domains of cartography: Orthomap production and map updating. As a base for in-time updating orthomaps became more and more important. Up to now large scale mapping (scales > 1:10,000) is done nearly exclusively with aerial photographs. It can be shown that the digital data sets of the new camera generation can be used operationally for the production of orthomaps. A fully automated processing line provides the ortho images very shortly after aquisition, due to the used high precision navigation system the accuracy of the data is very high, even very big scales can be realized. A comparison of digital cameras and aerial photos discusses and rates the properties of the different aquisition systems and data sets. For interpretation data sets of the digital camera HRSC-A were used. The High Resolution Stereo Camera - Airborne (HRSC-A) digital photogrammetric camera and its processing software provides the geoinformation industry for the first time with an entirely digital and fully automatic process to produce highly accurate digital image data. The pixel size ranges between 10 and 40 cm (flight altitude 2500 - 10,000 m). The airborne camera combines high resolution, photogrammetric accuracy and all-digital acquisition and provides both multispectral and elevation information. The pushbroom instrument provides digital ortho-images and digital surface models with an accuracy of 10-20 cm. The use of this wide range of image information showed to be very helpful for data analysis. This investigation focuses on the problems of automated interpretation of high-resolution data. These data sets make high demands on automated interpretation procedures. The richness of details depicted in the data sets complicates the interpretation, coarser spatial resolutions smooth out spatial complexity within heterogeneous land cover types, such as urban, and make an automated interpretation easier. This report shows that conventional interpretation techniques like pixelbased classification (supervised or unsupervised) do not lead to satisfactory results. Two new object-oriented and region-oriented approaches for the interpretation of high resolution data sets were developped and discussed. The parcel-based approach showed good results in interpretation of the data. The proposed methodology begins with an unsupervised per-pixel classification to identify spectral clusters which represent the range of scene components present in the pre-defined land parcels. The per-parcel analysis extracts the pixels classified as scene components within the land parcel under examination and calculates the total numbers and fractions for each scene component present. To identify land cover types not represented by scene components at the land parcel level, it is necessary to process the scene component information and infer relationships between the scene components present and land cover type. A set of rules was devised to identify a range of land cover types from the mixtures of scene components found within each land parcel. Secondly an object-oriented and multi-scale image analysis approach was used for the interpretation of single objects. The procedure contains two basic domains. The strategy is to build up a hierarchical network of image objects which allows to represent the image information content at different resolutions (scales) simultaneously. In a second step the image objects were classified by means of fuzzy logic, either on features of objects and/or on relations between networked objects operating on the semantic network. The procedure showed very good results in detecting houses and updating vector data sets. Segmenting the data in semantic units and performing further analysis on these units showed to be very helpful for interpretation. It could be shown that for analysis of urban areas the use of a Digital Surface Model is necessary. Due to the spectral similarities of image elements the elevation information offers an important additional tool for analysis.

Tato diplomová práce se pokouší studovat dvě techniky používané při natáčení pohybujícího se úhlu pohledu ve filmech - kapesní kameru a Steadicam - k analýze toho, jak přispívají nebo zlepšují "realismus" ve filmu. K tomu dochází přezkoumáním stávající literatury o pohybu kamery a popsáním historie těchto dvou technik. Tato diplomová práce se také zabývá tím, jak byl pohybující úhel pohledu kinematograficky zachycován do dnešního dne. Na základě historického základu tato diplomová práce staví svůj teoretický předpoklad, mimořádně podpořený Andre Bazinovou teorií o filmovém realismu či filmy a představami o kinematografii, které uvedl Robert Bresson. Nakonec tato práce formuluje novou klasifikaci úhlu pohledu a perspektiv a analyzuje dva filmy (LászlóNemesův SonOfSaulaGusVanSantův Elephant) ,přičemžkaždý používá jednu z těchto technik natáčení pohybujícího se úhlu pohledu. Tímto způsobem se pokouší o pochopení, která z těchto technik pohybu kamery je nejblíže k dosažení "realismu" a představě kinematografie, jak je šíří Bresson.

Dagens teknik erbjuder en mängd olika sätt för människor att kommunicera och interagera med varandra. Denna uppsats är en studie i bilddelning på sociala medier med fokus på amatörfotografers användande av tekniken i syfte för att nå ut med sina fotografier. Huvudfokus lades på vad för strategier de använde sig av, men även på användarnas olika målsättningar. Med hjälp av tidigare forskningsarbeten och djupgående intervjuer har vi lyckats återkoppla den egna empirin med våra teoretiska utgångspunkter och dragit slutsatsen att användandet av sociala medier i syftet för att nå ut med sina bilder till andra människor varierar väldigt stort från person till person. Hur tekniken används för detta syfte är därmed unikt för den individuelle användaren, dock har vi lyckats identifiera vissa likheter i användandet av sociala medier i dessa syften. / Today’s technology offers a variety of ways for people to communicate and interact with each other. This paper is a study of photo sharing through social media networks with a focus on the amateur photographers’ usage of this technology in order to widen the spread of their pictures. A key focus was placed on what kinds of strategies were used, but also on what kind of motivations the photographers had. Using previous research and in depth interviews we’ve managed to combine our own empirical data with our theoretical interpretations and have come to the conclusion that the use of social media in the purpose of reaching out with photos to other people varies greatly depending on the person being asked. Thus, how this technology is used depends wholly on the individual user. However, we have managed to identify some similarities in the usage social media for these purposes.

The overall objective of the thesis was to investigate how older family caregivers in rural areas experienced participation in an e-health based caregiver support system. Participants were 95 caregivers allocated to intervention group (n=63) and control group (n=32). The thesis had a mixed method design and is based on four original articles (I-IV). Data was collected through web-camera interviews (I-III), telephone interviews (II,IV) and questionnaires (II,IV) after 1.5 years of using e-health support. Quantitative data was analyzed using comparative statistics, multiple linear regression and logistic regression. Qualitative data was analyzed with content analysis. Article I showed that the caregivers, despite lacking experience from using computers, were able to adopt the new technology, with help from support nurses and family. Caregivers felt e-health helped them to regain social inclusion. Article II had a comparative design, comparing e-health support with conventional caregiver support. Caregivers using e-health were more satisfied with their support and found it to be available, flexible and helping them enhance caregiver competence. Control group caregivers were less satisfied with support and experienced unmet needs. Article III showed that e-health can reduce caregivers’ feelings of isolation. Two themes were created, Expanding the concept of place and Developing networks. Article IV revealed that caregivers used e-health frequently, experienced benefits from using it and had become more independent. Support nurses were disappointed about the decrease in contact with caregivers, and also acknowledged a need for developing the professional nursing role while working with e-health. Conclusions drawn from the findings were that participants experienced benefits from e-health support and it helped them become more independent. Swedish municipalities are obliged to provide caregiver support, the findings from the study are valid to conclude that e-health support are as good as, or even more effective, than conventional support for older family caregivers in rural areas. / Det övergripande syftet vara att undersöka hur äldre anhörigvårdare på landsbygden upplevde att få anhörigstöd via en e-hälsa-tjänst. Avhandlingen hade en mixed method design och bestod av fyra originalarbeten (I-IV). Deltagare i studien var 95 personer, boendes i gles- och landsbygdsområden, som i det egna hemmet vårdade en make eller maka med kronisk sjukdom. Deltagarna var fördelade på interventionsgrupp (n=63) och kontrollgrupp (n=32). Datainsamling skedde efter 1.5 års användning av e-anhhörigstödet, genom web-kamera intervjuer (I-III), telefonintervjuer (II,IV) och frågeformulär (II,IV). Kvantitativa data analyserades genom komparativ statistik, multipel linjär regression och logistisk regression. Kvalitativa data analyserades med innehållsanalys. Artikel I visade att anhörigvårdarna, även om de inte hade någon vana av datorer sedan tidigare, kunde lära sig och bli användare av den teknik och utrustning som ingick i e-anhörigstödet, när de fick hjälp och stöd av anhörigstödjare eller andra. Anhörigvårdarna upplevde att e-anhörigstödet hjälpte dem att återfå social delaktighet. Artikel II hade en komparativ design och jämförde e-anhörigstöd med traditionellt anhörigstöd. De som använde e-anhörigstödet var nöjda med stödet i högre utsträckning än de som fick traditionellt stöd. E-anhörigstödet upplevdes som tillgänglig, flexibelt samt bidrog till att de utvecklade sin kompetens i vårdandet. Kontrollgruppen var mindre nöjd med sitt stöd samt upplevde att de hade behov som inte tillgodoseddes av stödet. Artikel III visade att e-anhörigstöd kan minska anhörigvårdares upplevelse av isolering, dels genom att de upplevde en känsla av att vara på andra platser fast de rent fysiskt befann sig i hemmet, dels genom att de utvecklade sociala nätverk. Artikel IV visade att anhörigvårdarna ofta använde e-anhörigstödet och att de upplevde nytta av att använda det. De blev också mer självständiga vilket ledde till färre kontakter med anhörigstödspersonalen. Personalen kände viss besvikelse över att kontakterna iv med anhöriga minskade och uttryckte att den professionella omvårdnads-rollen behöver utvecklas när e-hälsa införs och tillämpas i vård- och omsorgsarbete. Slutsatser som drogs från fynden i avhandlingen var att anhörigvårdarna hade stor nytta av att använda e-anhörigstöd samt att det hjälpte dem att bli mer självständiga, vilket reducerade deras behov av kontakt med kommunernas anhörigstöd. Sveriges kommuner har en skyldighet enligt lag att tillhandahålla anhörigstöd, med stöd av fynden från den här studien kan man dra slutsatsen att e-anhörigstöd kan fungera lika bra som, ibland till och med effektivare än, traditionellt anhörigstöd.

This thesis deals with the use of the video as a didactic tool in the education of the physics. Introductory part is theoretic and focuses on classification of didactic tools which can be used for physics teaching. Second part analyses the possibility of capturing physical effects, especially effects with very long or very short duration which cannot be captured by conventional devices. This part is focused on the right selection of physical effects, selecting and setting of suitable devices for capturing and further processing of the recorded video. The next section is based on the previous analysis of physical effects, which are recorded and processed into the form of educational movie. The main result of this thesis is the collection of educational movies of fast and very slow physical effects useful as the didactic tool for the teaching of physics.

The master's thesis is devoted to the history and performance of non-contact temperature measurement, characterization of infrared cameras and infrared thermometers. Temperature is one of the most important physical quantities. Using an infrared camera we obtain information about the surface temperature in all picture. In the master's thesis is included the measurement and capturing the fatal defects on the punched billet, finding out the quality of temperature field and the quality of the overlapping work rolls. During the measurements were used infrared cameras TIM200, TIM400 from the company Micro-Epsilon and infrared cameras SC325, SC660 from the company Flir.

The aim of the dissertation was to present technical possibilities of scanning and measuring the body temperature and provide a method for a non-contact measurement of body surface temperatureof animals including data transfer to higher-level software. Partial results can be part of an automated herd management system to ensure better animal welfare monitoring. One method of contactless measuring the surface temperature was taking the surface temperature by using an infrared camera. This tool was used to scan surface temperatures in the area of the body core, the udder region and the eye area. Thermograms, sometimes referred to as thermal imaging, were obtained from the individual regions. In total, there were 34 measurements in 2013 and 17 measurements in 2014.Cows from Petrovice centre were included in the experiment. Three different groups of dairy cows were evaluated in two different stables. In the first group there were cows which gave birth 2 days to 2 months before. The second group consisted of dairy cows which calved 4 to 5 months before. The third group included dairy cows which gave birth 7 to 8 months before. Based on the results of measurements of selected surface temperatures, it was found that the surface core temperature and the udder surface temperature correlated most. However, when measuring surface temperatures, the degree of pollution, coating, and oscillation of the animal play an important role. Moreover, technological parameters of the device are also important, specially its setting and the emissivity of the surface. This experiment ran from August to September 2016 in a purpose-built schoolhouse facility in an experimental stable accredited for experimental purposes. The experiment included two clinically healthy cows of the Holstein breed, which had been implanted with the identification chip and tested for its functionality. This chip was implanted to both animals in the tail root region and was fitted with a biological function sensor that followed the body temperature of the animal. The device was adapted to send animal identification information and animal body temperature information by means of a wireless connection to the chip reader. Based on the findings, one or more systems, preferably non-contact body temperature scanning, could be designed and tested. Regarding the use of other surface temperature scanning possibilities, this is still in the process of development and implementation. The disadvantage of the above described device is that it fails to recognize the cause of the elevated temperature and requires intervention by the attendant without the intervention being necessary. The attending keeper may not recognize acute cases and may cause permanent damage to the health or even death of the animal. The task of the device is to find a method of unattended animal temperature measurement connected with its electronic identification that would recognize sick or infected animals from overheated ones. This device would categorize the animals and take precautions to preserve their health. The invention should be applicable to a wide variety of animals.
