Possibilities of Point Cloud and Mesh Model Creation of Accident Site Using Photographs
Mojžyšek, Tomáš ; Bradáč, Albert (referee) ; Křižák, Michal (advisor)
The thesis focuses on creating point cloud and mesh model of chosen intersections and their applications in forensic-engineering praxis. In the first part, we describe a workflow for creating point cloud and mesh model of intersection by digital photogrammetry. In the second part, we applied these at chosen intersections. Which leads us to the comparison of three digital photogrammetric programs which we used to make point clouds and mesh models. At the end of thesis, we use our mesh models in forensic-engineering praxis and we decide about barriers in sign conditions at intersections.

Creation of 3D model of building using laser scanning
Sabo, Stanislav ; Kalvodová, Petra (referee) ; Kalvoda, Petr (advisor)
The aim of this thesis is to scan the part of the interior and exterior of the Faculty of Electrical Engineering and Communication building using the FARO Focus3D X 130 scanner, and the creation of a 3D model in the WGS 84 system. Subsequently, methods, status and utilization research of this technology and point cloud processing software is provided. The collected data are processed in the SCENE. Three-dimensional model is designed using the Pointfuse and Microstation V8i programs. In the end, the registration accuracy of the scans and the resulting 3D model accuracy are evaluated.

Digital terrain model for morphological purposes
Olšovský, Vít ; Tajovská,, Kateřina (referee) ; Hanzl, Vlastimil (advisor)
The aim of the thesis is measuring a part of a Svratka’s meander by the means of the FARO focus 3D X 130 scanner and a total station. Another part of the thesis is creating 3D models from individual methods and their comparison. The acquired data is processed in the SCENE, Microstaion Power Draft V8 and Atlas DMT programmes. The accuracies of the scan registrations and the resulting differences among individual methods are evaluated.

Digital terrain model in the area of Admas
Kroupa, Ondřej ; Kalvoda, Petr (referee) ; Hanzl, Vlastimil (advisor)
The goal of this thesis is to scan part of the complex research center AdMaS using terrestrial laser scanner, from obtained data draw up a 3D terrain model and compare the height accuracy with conventional terrestrial measurement. The thesis is focused to software, which allow processing of point clouds and prepare the 3D model. The output of this work is the 3D terrain model and two transverse profiles for vertical comparison of two measurement methods.

The surveing of specific elements in the area of Admas
Koukal, Pavel ; Kalvoda, Petr (referee) ; Hanzl, Vlastimil (advisor)
The diploma thesis consists of two fundamental parts. The first part is focused on scanning a section of the Admas area by a terrestrial laser scanner. This section describes the introduction to laser scanning, necessary utilities and software, fieldwork, the process from the registration of a point cloud, through point cloud processing to its connection into the S-JTSK. The second part of the thesis is mostly focused on execution of the digital model of the relief from the acquired data. It also deals with the two methods of creating a cross-sectional drawing of the area - one is based on the digital model of the relief and the other on data obtained by the polar method. The outcome of the thesis is to assess the accuracy of the topographical model, based on the comparison with the polar method.

Terrestrial laser scanning
Endlicherová, Lucie ; Volařík, Tomáš (referee) ; Hanzl, Vlastimil (advisor)
This diploma thesis is focused on determine the characteristics of accuracy of the terrestrial laser scanner FARO Focus 3D S120. It is validated the recommended distance between the objects (targets and spheres) and the terrestrial scanner. Next it is tested accuracy of the Cartesian coordinates X, Y, Z measured by laser scanning with resolution 1/2. At the end it is investigated the accuracy of the area determination in X coordinate gained by the scanning of a smooth slightly curved surface.
