Determination of bench-mark heights in the FAST Žižkova local leveling network
Poštulka, Lukáš ; Weigel, Josef (referee) ; Machotka, Radovan (advisor)
The purpose of this bachelor's thesis is to precisely determine the heights of the leveling points of the local leveling network in the premises of the Faculty of Civil Engineering of the University of Technology in Brno on Žižkova and Veveří streets. A precision leveling method was used to achieve this goal. The bachelor's thesis focuses on the description of the measurement methodology, the technology used, the preparation for the measurement and then the measurement itself. Then it deals with the processing of the measured values, their equalization using the method of least squares, as well as the analysis of the accuracy of the results. The results of this work are the altitudes of the points that are used for the creation of leveling data and overviews of the points of the leveling network.

Documentation of Barová cave - northeastern part
Nováková, Zuzana ; Weigel, Josef (referee) ; Kratochvíl, Radim (advisor)
Bachelor thesis looks into speleological mapping of the northeastern part of the cave system Barová cave, namely of the passages IV. abyss, V. abyss and Jezerní dóm, which is located under the V. abyss. The introductory section introduces the cave location a gathering available data. Following the reconnaissance of the location and the existing survey network, the documentation of the location was carried out with detailed measurements using Disto X2 and sketching on a tablet in the Topodroid program. The result of the work is a ground plan including cross-sections and a developed longitudinal section at a scale of 1:250, in the JTSK coordinate system and the Bpv height system.

Deformation surveying of structures with GNSS technology
Dikoš, Martin ; Weigel, Josef (referee) ; Švábenský, Otakar (advisor)
The thesis of this bachelor's work was the measurement and evaluation of shifts on the assigned construction objects. The observed construction is Královopolský tunnel and Ivančický viaduct. The measure was done using the GNSS technology and the statical method. Assessment of the provided data from previous measurements, and measurements of the data done in TBC software. From the evaluation of the data, an assessment of horizontal and vertical shifts occurs.

Accuracy testing of minor horizontal geodetic control determined by analytical aerotriangulation
Komárek, Josef ; Weigel, Josef (referee) ; Kratochvíl, Radim (advisor)
The purpose of this bachelor’s thesis is testing quality of minor horizontal geodetic control points in chosen area in South Bohemia. The control points have been established in the eighties of twentieth century during cadastrial mapping (large scale base map). Until now, those points were recorded in the 4th accuracy class. The geodetic control was remeasured with RTK technique, then deviations were calculated. These results were reviewed and evaluated whether the points match with the 4th accuracy class or even the 3rd accuracy class. The results were submitted to the local cadastral office in Jindřichův Hradec.

Repeated GPS measurements at Tetčice polygon and its interpretation
Dvořák, Jiří ; Josef, Weigel (referee) ; Pospíšil, Lubomil (advisor)
This thesis deals with monitoring shifts in the vicinity of the village Tetčice. The site is located at the interface of geomorphological units. Monitor the area is done in stages and methods of using GPS and precise leveling. Points tested are expected movements in places the earth's crust, which are stabilized on the pillars in order to avoid possible negative effects. The work builds on results from previous measurements.

Sensor Calibration for Multispectral Data Fusion in Mobile Robotics
Kalvodová, Petra ; Hanzl, Vlastimil (referee) ; Mazal,, Jan (referee) ; Pospíšil,, Jiří (referee) ; Weigel, Josef (advisor)
Thesis deals with data fusion and calibration of sensory system of Orpheus-X3 robot and EnvMap mapping robot. These robots are parts of Cassandra robotic system that is used for exploration of hazardous or inaccessible areas. Corrections of measured distances are determined for used laser scanners Velodyne HDL-64, Velodyne HDL-32 and range camera SwissRanger SR4000. Software MultiSensCalib has been created and is described. This software is used for determination of intrinsic parameters of heterogeneous cameras of the sensory head and for determination of mutual position and orientation of these sensors. Algorithm for data fusion of CCD camera stereo pair, thermal imager stereo pair and range camera is proposed. Achieved calibration and data-fusion parameters are evaluated by several experiments.

Gravity measurements and repeated leveling at polygon Tetčice.
Zajíčková, Katarína ; Weigel, Josef (referee) ; Pospíšil, Lubomil (advisor)
The object of this master´s thesis was levelling and weight measurement of the Tetčice polygon through which passes the fault of the Boskovice furrow. This is the 10th period of levelling and the second period of gravimetric measurement. The theoretical part describes the geological structure of the site, technology of high-precision levelling and technology of gravimetric measurement. The first part of the practical part deals with my own levelling measurement, the calculation of the resulting cambers and heights, consequential comparasion of the results with previous periods and, especially, with evaluation of the vertical movement tendecies. The second part of the practical part deals with my own gravimetric measurement, the calculation of the complete Bouguer gravity anomaly, creation map of complete Bouguer gravity anomaly and as well as evaluation of gravimetric measurement in relation to the results of the previous periods.

Deformation Surveying with GNSS technology
Míča, Vojtěch ; Weigel, Josef (referee) ; Švábenský, Otakar (advisor)
This bachelors thesis sets the task to measure, process and evluate data obtained through static GNSS method on a point in a network used to set out Královopolský tunnel, these measurements were obtained in the years 2002, 2004 and 2022. The other GNSS measurements were carried out on points in geodynamic network „Sněžník“ which were obtained between years 2012 and 2022. All of these measurements should be proccessed through Trimble Business Center. Based on the results it should reveal possible horizontal and vertical deformations in the direction to default points.

The measurement of the levelling network in a part of Brno
Sotolářová, Tereza ; Švábenský,, Otakar (referee) ; Weigel, Josef (advisor)
The measurement of the levelling network in a part of Brno The theoretical part of this study deals with the theory of heights, marking, stabilization of benchmarks and the history of Area of benchmarks in Brno. The practical part of this study is devoted to the levelling network, the method of the accurate levelling, the implementation of the corrections and the calculations of elevation difference, followed by evaluation degrees of accuracy of vertical distance. The results of the study were used for the project Specific research „Development of new methods in Geodesy measuring“, surveying with GPS and astronomical measuring.
