Detection of spatial objects in a point cloud
Venený, Petr ; Machotka, Radovan (referee) ; Volařík, Tomáš (advisor)
The diploma thesis deals with processing of a point cloud that was collected via mobile mapping system. The first part sets a theoretical background, starting with mapping in general moving to mobile mapping systems and their particular parts. The practical part describes the whole process of data collecting, testing the automatic detection of spatial objects based on a point cloud and its visualisation. The results of the diploma thesis are GIS data layers and an evaluation of the process.

Testing of an Accuracy of Mobile Laser Scanning
Hoffmannová, Lada ; Volařík, Tomáš (referee) ; Kuruc, Michal (advisor)
Diploma thesis describes collecting of data by mobile mapping system Riegl VMX-450. Science centre AdMas was captured with mobile mapping system. For the purpose of testing the accuracy, a calibration field was constructed in AdMaS. Main part of the thesis deals with testing of the accuracy of point cloud. Calibration field's coordinates were obtained by adjustment of the geodetic network using the least squares adjustment. During the testing, the coordinates of the calibration field points determined by the adjustment of the geodetic network and the coordinates of the points determined from the point cloud were compared. Another part of the work deals with testing of the accuracy, when target's position is in different height levels.

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.

Revision and survey of large scale thematic map of the surface situation
Fodor, Alexander ; Kratochvíl, Richard (referee) ; Kalvoda, Petr (advisor)
The main content of this bachelor’s thesis was updating the surface map in the Staré Hradište 2 location. The update was performed using a mobile mapping system. The GeoStore V6 programme by GEOVAP, spol. s r.o. was used to process point clouds. After evaluating the point clouds, the areas insufficiently covered by the point clouds were measured using the polar method from positions whereby the coordinates and heights were determined by the GNSS-RTK method. The resulting map was tested according to ČSN 01 3410 and the advantages and disadvantages of both data collection methods were compared at the end of the thesis. The resulting map was checked by GEOVAP, spol. s r.o. and subsequently entered into the Digital Technical Map of Eastern Bohemia database, which is handled by the Association of Network Administrators of Eastern Bohemia.

Accuracy testing of mobile mapping system MOMAS
Nováčková, Soňa ; Kohout, Jan (referee) ; Hanzl, Vlastimil (advisor)
The aim of this thesis is to introduce the mobile mapping system MOMAS, which is owned by Geodis Brno, spol. s.r.o. and test the accuracy of the system. Perform data collection and processing of data in the workplace company Geodis. In addition, identical target points, determine their coordinates and compare them with the coordinates obtained MOMAS system. And finally processed statistically derived coordinate differences.

Geodetic Monitoring of Bridge Abutment
Kinc, Martin ; Bureš, Jiří (referee) ; Bárta, Ladislav (advisor)
The bachelor's thesis deals with the measurement and evaluation of the deformation of the bridge abutment and the adjacent embankment in Ostrava on the road I / 56 Ostrava - prodloužená Místecká. The main part of the work deals with the implementation and processing of one stage of measurement to evaluate the displacements of these buildings using the methods of geometric leveling from the center, polar method, groundbased laser scanning mobile mapping system and multistation MS60. The next part of the work deals with the comparison of individual methods. The achieved results are interpreted in graphs, tables and also shown by color hypsometry.

Revision and survey of large scale thematic map of the surface situation
Prokop, Jaromír ; Cimpl, Pavel (referee) ; Kalvoda, Petr (advisor)
The subject of this bachelor thesis is the revision of the large scale thematic map of the surface situation in the village Staré Hradiště. The map was updated by combining data from a mobile mapping system and a field survey using polar method and GNSS. Accuracy of the updated map was tested according to ČSN 01 3410. The advantages and disadvantages of map updating by mobile mapping and classic methods were compared.
