Využití programu PHOTOMODELER v soudně inženýrské praxi / Use of PhotoModeler program in forensic engineering practice

Zdražilová, Alena January 2015 (has links)
The main task of this thesis is to find out dimensions of family house from photos and after that use this dimensions to create a 3D model. Another task is to create and then test optimal procedure of taking photographs of house for the purpose of work in PhotoModeler software and subsequent processing in Autocad. The result is a model that serves for creation of sections and taking measurements necessary for valuations of a family house. The optimum process should be a compromise of the simplest and the most accurate method of creating 3D models.

Inter-population craniometrics of adult male Subantarctic fur seals (Arctocephalus tropicalis)

Moshobane, Moleseng Claude 03 1900 (has links)
Craniometrics is a very reliable and effective tool for studying the difference in animal morphology. Previously, traditional craniometrics were conducted with the aid of calipers in two dimensional format (2D). Such discounting of actual three-dimensional 3D form may result in loss of some relevant and critical information leading to compromised and unreliable results for studies such as population variation analysis of morphology. The employment of 3D photogrammetry allows a close to complete representation of the physical dimensions of a specimen. The use of photogrammetry in mammalogy concentrated on measuring of body size/mass, but little has been done on animal skull delineation through photogrammetry. This dissertation describes advances in morphometrics and 3D photogrammetry application in craniometrics, investigates the craniometric variation between closely related species (Arctocephalus gazella and A. tropicalis), and A. tropicalis interpopulation craniometrics between two geographically distinct populations, at Marion Island and Gough Island, using Photomodeler Scanner® (PMSc®) three-dimensional (3D) modelling software to produce accurate, high resolution 3D skull models. A total of 117 3D models were created from adult male fur seal crania, and 16 traditional measurements recorded, using specimens archived at the Port Elizabeth Museum, Bayworld, South Africa. Sixteen linear measurements, (8 caliper recordings and 8 3D recordings) were used for PMSc® methodology testing, 16 (A. gazella n= 8 and A. tropicalis n= 8) used for species cranial comparison and 85 (Marion Island n= 54 and Gough Island n= 31) used for interpopulation variation. The craniometric variations were analysed using the Statistica® v11 software package, StatSoft, Inc. The comparison between linear traditional caliper cranial measurements and 3D measurements produced significantly similar results, attesting to the accuracy of the PMSc® 3D model production. Photomodeler Scanner® therefore produces accurate and high resolution 3D models of skulls which allow 3D measurements. I predicted that PMSc® would detect the existing significant differences between the skulls of adult male A. gazella and A. tropicalis and modelled and compared their 3D models, and I further predicted that PMSc® would detect any existing differences between the skulls of A. tropicalis from Gough and Marion islands by comparison of their 3D models. The Gough Island and Marion Island A. tropicalis populations could not be discriminated based on linear 3D cranial I conclude that PMSc® is a reliable and effective tool for accurate and high resolution 3D modelling. The present study confirms previous findings and contributes additional evidence that suggests that adult A. tropicalis males from Gough Island and Marion Island cannot be discriminated based on linear measurements of craniometrics, and deviates from the Bergmanian rule as applied to large mammals. The present study, however, makes several noteworthy contributions to the use of PMSc® and 3D modelling in morphometrics. Taken together, these findings suggest a role for PMSc® 3D modelling in promoting accurate digitization of museum specimens and creation of online museum libraries. This research will serve as a baseline for future studies and usefulness of PMSc® in 3D morpho-volumetric measurements. / Dissertation (MSc (Zoology))--University of Pretoria, 2014. / Zoology and Entomology / MSc (Zoology) / Unrestricted

3D model vybraného objektu / 3D model of the selected object

Raclavský, David January 2020 (has links)
The result of the diploma thesis is a photogrammetrically evaluated georeferenced 3D model of an object with its environment, located in the AdMaS complex. The work describes in detail all phases of creating a 3D model of the object from the selection and calibration of the camera to editing the 3D model. Discuss about software and methods for evaluating 3D models. The thesis deals with the optimal setting of ContectCapture software. The accuracy of the resulting 3D model is tested by the methodology according to ČSN 013410 on the basis of control measurements.

Využití fotogrammetrie pro realitní praxi / The Use of Photogrammetry in the Real Estate Practice

Viktora, Jakub January 2014 (has links)
This diploma thesis aims to explore possibilities of using IT in real estate and projection practice. It deals with simplification of difficult or insolvable tasks. It focuses on rapidly developing field of photogrammetry and its further processing via software. The work presents methods of measurement of existing realties without using standard methods (tape line, laser). Instead of these tools, the author uses photographic data and program PhotoModeler for surveying and creating a 3D model of the facade. The thesis verifies further serviceability of gained data up to the render phase of the surveyed building facade.

Využití fotogrametrie v oboru znalectví ve stavebnictví a oceňování nemovitostí / Use of photogrammetry expertise in the field of construction and real estate valuation

Slabotinský, Filip January 2015 (has links)
The task of this diploma thesis is to design and test the optimal procedures for taking photos to build a 3D model of a civic building using the programme PHOTOMODELER. Then to determine the specific dimensions of the civic building and compare them with the dimensions received with the help of the basic method of measurement in common building practice, i.e. the method of cross directions (using a tape or a telescopic measuring rod) and the geodetic method of measurement. After that to evaluate these measurements and make the conclusion concerning the accuracy or inaccuracy of measurements received with the help of the 3D model of the compiled programme PHOTOMODELER.
