Design of Pravčická brána 3D model and its integration with 2.5D TIN terrain model
Brýdl, Ivo ; Brůha, Lukáš (advisor) ; Lysák, Jakub (referee)
The main goal of this thesis is to design integrated model containing a three-dimensional representation of Pravčická brána rock arch and 2.5D TIN model of surrounding terrain. Point cloud from airborne lidar measurements has to be classified into ground and non-ground features. The ground points are the basis of the TIN terrain representation. Second part of this thesis is focused on methods for reconstructing 3D surface from given points set retrieved with ground-based lidar measurement. The thesis describes the process of meshing point cloud with Poisson surface reconstruction. Finally, these two models are oriented and translated to real coordinates in order to form integrated hybrid model covering part of České Švýcarsko National Park.

Creating a 3D model of the White Tower in Hradec Kralove from terrestrial laser scanning data
Lagner, Ondřej ; Čábelka, Miroslav (advisor) ; Štefanová, Eva (referee)
This work is focused on processing data of digital terrestrial laser scanning of The White tower in Hradec Králové city and solving the problems closely connected to this. Data was processed in different graphical softwares, which were specialy made for this kind of tasks. During the processing, the softwares were compared according to established criteria. The mos usefull pragram Geomagic Studio 2012 was chosen and 3D model of the tower was made in this. To assess the accuracy of the model, was it measured by yardstick, and model was also compared with buildings plan.

Visualization Environment for Robot Remote Control
Blahož, Vladimír ; Polok, Lukáš (referee) ; Španěl, Michal (advisor)
This thesis presents possibilities of 3D point cloud and true colored digital video fusion that can be used in the process of robot teleoperation. Advantages of a 3D environment visualization combining more than one sensor data, tools to facilitate such data fusion, as well as two alternative practical implementations of combined data visualization are discussed. First proposed alternative estimates view frustum of the robot's camera and maps real colored video to a semi-transparent polygon placed in the view frustum. The second option is a direct coloring of the point cloud data creating a colored point cloud representing color as well as depth information about an environment.

Working out of methodology for creation of building information mode
Sládková, Veronika ; Černý, Martin (referee) ; Hanzl, Vlastimil (advisor)
The subject of thesis was creation of methodic for building information modeling methods specified. The buildings were surveyed at first or projects drawing were provided. Processing of survey data and building information modeling was done in software Revit 2014 with program extensions. Subsequently chosen methods of creation were described and they were compared with each other. The result can use for selection the most appropriate method on the basis function and targeted funds.

Mobile Mapping
Manda, David ; Sukup, Jan (referee) ; Hanzl, Vlastimil (advisor)
The aim of this thesis is introduce the mobile mapping system IP-S2, which is using by company GEODIS BRNO, and perform data collection by this system. Measure the identical points, determine their coordinates and compare with coordinates obtained by mobile mapping system. The conclusion of this thesis is focused on testing the accuracy of the mobile mapping system.

Laser scanning confocal microscopy for 3D surface mapping
Lapšanská, Hana ; Schovánek, Petr
This contribution introduces a modern microscopic method and shows possible measurements and analysis of wire saw machined glass pieces. The main objective of realized measurements is to identify possible defects and its depth to propose eventual additional treatment. We are looking for the optimal technological procedure of grooved glass stick-on supports preparation. Such supports are used for the very thin accurate optical components production which is executed in our workshops and laboratories. Surface quality of the support significantly influences the quality of produced optical components.
