Analysis of an accuracy of laser scanning
Vacová, Dominika ; Kohout, Jan (referee) ; Volařík, Tomáš (advisor)
The main goal of this master thesis is processing a point cloud with respect of possibilities of a registration clouds based on reference objects or on objects in general. This thesis studies transformations to the reference coordinate system S –JTSK. The first part of this thesis describes a theoretical background of the laser scanning and its use. A practical part shows the results and the evaluation of whole research.

Evaluation of laser scanning for 3D modelling
Oboňová, Veronika ; Kohout, Jan (referee) ; Volařík, Tomáš (advisor)
The aim of the diploma thesis is to create a 3D model of the given object using laser scanning technology. Subsequent adjustments of the model and its separate preparation for possible 3D printing will be done through appropriate programs. The next 3D model of the identical object will be made based on the created photos and will be edited and prepared in the same way for possible 3D printing.

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.

Utilization of optical and laser data for modeling forest areas
Jebavá, Lucie ; Potůčková, Markéta (advisor) ; Dušánek, Petr (referee)
The thesis deals with the possible use of optical data for modeling forest area compared with utilization of airborne laser scanning data. At first these two datasets are compared and causes of differences are explained. Then canopy height models are made and object-oriented classification is applied for separation of vegetation stands. Methodical procedure is suggested for delineation and detection individual trees in forest. Then their height is detected. There are summarized and other possibilities for improvement in detection and delineation of trees. The results show that optical data with resolution about 25 cm are suitable for dermining the characteristics of the forest stands up to individual tree level. The outputs of this research can be used for forest inventory. Key words: aerial imagery, image matching, laser scanning, point cloud, forest inventory

SBU_1702
Hanuš, Jan
The purpose of aerial hyperspectral campaign with laser scanning of surface over the Dehtare area (Českomoravská vysočina highlands) was to obtain data for the study of water vegetation stress in the agricultural landscape. The data sets were scanned using the Flying Laboratory of Imaging Systems of the Global change research institute CAS in spectral range 380-2450nm, 8000-11500nm and LiDAR cloud density of 0.5 point per m2. Georeferenced and atmospherically corrected hyperspectral data was passed in spatial resolution 2 and 5m.

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

Documentation bridge using terrestrial scanning
Ferencová, Anna ; Kalvoda, Petr (referee) ; Hanzl, Vlastimil (advisor)
The aim of this bachelor work is to scan with help of ground-based scanner bridge structure, which is part of the area of faculty of building VUT in Brno. Content of this work is theoretical base and consecutive practical elaboration of measured data. The result is effectuation of 3D model and examination of accuracy on control points.
