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.

Determining floor flatness using laser scanning
Matušková, Klára ; Kalvodová, Petra (referee) ; Kalvoda, Petr (advisor)
The aim of the diploma thesis was to determine the flatness of the floor using two methods, levelling and laser scanning, their subsequent comparison and evaluation of differences between them. The thesis deals mainly with laser scanning and namely the used scanner and the software for point cloud processing. Furthermore, there is a compilation of existing technical standards dealing with this topic.

GIS application methods in antropology
Bashir, Faraz Ahmed ; Štefanová, Eva (advisor) ; Potůčková, Markéta (referee)
This bachelor thesis aims to use of geoinformatic methods in anthropology. Specifically methods of terrestrial laser scanning and close range photogrammetry. The theoretical part focuses on explaining functioning and usage of those methods. Practical part of this work discribes data collecting proces with those methods and following creation of 3D model of anthroplogical artifact, specifically human skull. In the end those models are compared with model from computed tomography which was provided, same as anthropological artifact, by Department of anthropology and human gentetics of Charles University.

Measuring of facade of historical object by geodetic methods
OBERREITER, Milan
This study is focused on the ways of measuring the facade of the historical building. This activity has become more frequent in recent years due to the documentation of the status of architecturally valuable objects or the design of the renovation and the determination of the financial budget. The documented house is the house U Bílé labutě at Přemysl Otakar II. Square in České Budějovice.

Possibily GIS methods for documentation of paleontological relics
Čelonk, Marek ; Štefanová, Eva (advisor) ; Potůčková, Markéta (referee)
Possibily GIS methods for documentation of paleontological relics Abstract The bachelor thesis is focused on use of geoinformatic methods for creation of 3D model. The thesis is produced in cooperation with the Chlupáč's Museum of Earth History, which lent a paleontological artifact for processing. The theoretical part deals with laser scanning and close-range photogrammetry. Both methods are used in the practical part for own data colection and subsequent creation of 3D model. Data processing was mostly done in Trimble RealWorks, MeshLab and Agisoft PhotoScan. Another output is the HTML page that allows visualization in the Internet environment. key words 3D model, laser scanning, close-range photogrammetry, point cloud

Vytvoření 3D modelu jeskyně Koňská jáma z dat pozemního laserového skenování pro potřeby CHKO Moravský kras
Gaja, Martin
The thesis discusses the use of relatively new technologies laser scanning for speleology surveying. The impulse for the creation of this work are simple, in many cases inaccurate surveyings the caves, which are, since inception for a long time, used up to now. The work describes the process of data acquisition by terrestrial laser scanning, then their processing and outputs that can be present or work with them. It is also evaluated the appropriateness of using this method in speleosurveying and compared with the currently used methods.

Local scale snow accumulation and ablation variability using high spatial resolution data
Cuřín, Vojtěch ; Jeníček, Michal (advisor) ; Minařík, Robert (referee)
The focus of this bachelor's thesis is snow depth variability at local scale and modern methods of snow depth measurement with high accuracy, precision and resolution. The main goal is to provide an overview of current research in this area, give comparison of the most widely used methods and outline their most appropriate fields of application. A part of this work is also dedicated to an evaluation of snow distribution over a study area in Filipohuťský creek basin in Šumava (Bohemian Forest) and to an assessment of the impact of selected variables on snow depth variability using multiple linear regression models. This is done using manual snow depth measurement data and local digital surface model with high resolution. Multiple linear regression models capture the snow depth variability more precisely than models based on ordinary kriging, nevertheless the regression coefficients of selected predictors are too inconsistent to confirm their effect. Key words: snow depth, photogrammetry, laser scanning, multiple linear regression
