The surveing of specific elements in the area of Admas
Koukal, Pavel ; Kalvoda, Petr (referee) ; Hanzl, Vlastimil (advisor)
The diploma thesis consists of two fundamental parts. The first part is focused on scanning a section of the Admas area by a terrestrial laser scanner. This section describes the introduction to laser scanning, necessary utilities and software, fieldwork, the process from the registration of a point cloud, through point cloud processing to its connection into the S-JTSK. The second part of the thesis is mostly focused on execution of the digital model of the relief from the acquired data. It also deals with the two methods of creating a cross-sectional drawing of the area - one is based on the digital model of the relief and the other on data obtained by the polar method. The outcome of the thesis is to assess the accuracy of the topographical model, based on the comparison with the polar method.

Extraction of Landscape Elements from Remote Sensing Data
Ferencz, Jakub ; Kalvoda, Petr (referee) ; Hanzl, Vlastimil (advisor)
This master thesis deals with a classification technique for an automatic detection of different land cover types from combination of high resolution imagery and LiDAR data sets. The main aim is to introduce additional post-processing method to commonly accessible quality data sets which can replace traditional mapping techniques for certain type of applications. Classification is the process of dividing the image into land cover categories which helps with continuous and up-to-date monitoring management. Nowadays, with all the technologies and software available, it is possible to replace traditional monitoring methods with more automated processes to generate accurate and cost-effective results. This project uses object-oriented image analysis (OBIA) to classify available data sets into five main land cover classes. The automate classification rule set providing overall accuracy of 88% of correctly classified land cover types was developed and evaluated in this research. Further, the transferability of developed approach was tested upon the same type of data sets within different study area with similar success – overall accuracy was 87%. Also the limitations found during the investigation procedure are discussed and brief further approach in this field is outlined.

Creation of 3D model of building
Řehořová, Klára ; Volařík, Tomáš (referee) ; Hanzl, Vlastimil (advisor)
This bachelor´s thesis deals with surveying buildings in campus of Faculty of Civil Engineering, Technical University in Brno and consequential 3D model elaboration in graphic program SketchUp. The result is generalised spatial model of the B and C buildings FAST VUT. The emphasis was the aesthetics and symmetry not measurement exactness.

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.

Comparation of the Methods Generation of Tie Points in Aerotriangulation
Hromková, Zuzana ; Kalvoda, Petr (referee) ; Hanzl, Vlastimil (advisor)
The subjekt of this bachelor´s thesis is to compare the methods of generation of tie points in aerotriangulation using the program Photomod 4.3 made by Russian company Racurs. Part of this thesis is a detailed of description of the project initialization, subsequent implementation of aerotriangulation and bundle block adjustment in Photomod on those images. The result is a comparison of elements of exterior orientation. and coordinate determined points processed in tables and graphs.

Construction phase in the building information model
Richterová, Zuzana ; Hanzl,, Vlastimil (referee) ; Berková, Alena (advisor)
The diploma thesis deals with the creation of construction phases in the building information model, which were created with the use of data from the design documentation of passport, data from the actual measurements taken mainly by laser scanning and the design documentation of reconstruction. This thesis describes the procedure from fieldwork (acquisition of measurement data), through its processing, to the final drawings including also the model in *.rvt format. The focus of the thesis is on the project phases, for which the issues arising in their creation are described. The stumbling block in this thesis was the inconsistency in the design documentations, which was mainly reflected in the creation of the model of the reconstruction phase. All the pitfalls that occurred in the thesis are explained in the text.

Completing of horizontal control for landscape consolidation purposes
Novák, Jan ; Mokrý, Martin (referee) ; Hanzl, Vlastimil (advisor)
The aim of this bachelor thesis is the revision implementation and a proposal of new points for minor horizontal control completion, including the field realization. The new points were positioned by means of typical geodetic methods and with the help of the global navigation satellite system technology. Besides, the complete minor horizontal control documentation for landscape consolidation purposes is a part of the thesis.

Terrestrial laser scanning
Endlicherová, Lucie ; Volařík, Tomáš (referee) ; Hanzl, Vlastimil (advisor)
This diploma thesis is focused on determine the characteristics of accuracy of the terrestrial laser scanner FARO Focus 3D S120. It is validated the recommended distance between the objects (targets and spheres) and the terrestrial scanner. Next it is tested accuracy of the Cartesian coordinates X, Y, Z measured by laser scanning with resolution 1/2. At the end it is investigated the accuracy of the area determination in X coordinate gained by the scanning of a smooth slightly curved surface.
