Building Information Modelling of the Water Utility Objects
Maňas, Jaroslav ; Kubíčková, Miroslava (referee) ; Volařík, Tomáš (advisor)
This thesis deals with the BIM creating process with the use of laser scanning data in Revit software. It’s focusing mainly on MEP of water object. In the theoretical part of thesis there are outlined basic issues about laser scanning, informational modelling and other relating issues. In the practical part of the thesis is the summarization of procedure starting from data collecting, data processing to the procedure of creating BIM model, it’s visualisation and the use of the model. There are also mentioned useful pieces of knowledge, which I have learned during dealing with the problems related to the application of this new way of using the spatial information.

Visualization Environment for Robot Remote Control
Blahož, Vladimír ; Polok, Lukáš (referee) ; Španěl, Michal (advisor)
This thesis presents possibilities of 3D point cloud and true colored digital video fusion that can be used in the process of robot teleoperation. Advantages of a 3D environment visualization combining more than one sensor data, tools to facilitate such data fusion, as well as two alternative practical implementations of combined data visualization are discussed. First proposed alternative estimates view frustum of the robot's camera and maps real colored video to a semi-transparent polygon placed in the view frustum. The second option is a direct coloring of the point cloud data creating a colored point cloud representing color as well as depth information about an environment.

Design of equipment for welding head path correction
Benáček, Filip ; Jaroš, Aleš (referee) ; Slaný, Martin (advisor)
The work presents the problem of welding of membrane walls intended for application in power boilers. Furthermore, the use of the MIG/MAG method for welding and the advantages of using the CMT method. An innovation has been made for the welding process in the form of laser scanning of the surface and subsequent use of the data to correct the welding head. This led to the automation of the whole process. Because of the necessary testing of the laser scanner function, a test structure was designed and constructed. It was necessary to consider the appropriate wall scanning strategy and subsequent data processing in terms of the overall manufacturing process. The software designed to evaluate the scanned profile placed a point using a suitable tool on the scanned profile. The set of points was further filtered for a smoother resulting path formed by these points. The resulting points were fed to the output signal from the laser device to correct the path of the welding head. Both the welding and the surface scanning will be done simultaneously, so the settings for the laser scanner were created and stored in the internal unit of the device. This allows the laser to operate without connecting to a computer.

Creation of a purpose map of the castle courtyard by the laser scanning method
Kučeravý, Peter ; Kratochvíl, Radim (referee) ; Machotka, Radovan (advisor)
This diploma thesis is dealing with creation of thematical map of castle courtyard of the Veveří castle using the method of laser scanning. The thesis describes the construction of a survey net which is important for measuring control points and then scanning of the area using the scanner FARO Focus 3D. The thesis contains a description of the method of laser scanning and point cloud processing in Trimble RealWorks software. Furthermore, this thesis deals with the accuracy of the point cloud and compares the laser scanning method with the typical tachymetric method according to time duration.

Working out of methodology for creation of building information mode
Sládková, Veronika ; Černý, Martin (referee) ; Hanzl, Vlastimil (advisor)
The subject of thesis was creation of methodic for building information modeling methods specified. The buildings were surveyed at first or projects drawing were provided. Processing of survey data and building information modeling was done in software Revit 2014 with program extensions. Subsequently chosen methods of creation were described and they were compared with each other. The result can use for selection the most appropriate method on the basis function and targeted funds.

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.

Topographic model of the archeological site Stradonice based on UAV LiDAR point cloud
Prýmek, Jan ; Potůčková, Markéta (advisor) ; Hodač, Jindřich (referee)
The bachelor thesis is focused on the creation of a topographic model of the burial mound near Stradonice. The aim of the work was to filter LiDAR point clouds acquired from an UAV and aircraft platforms over the forested terrain of the area of interest, to analyze them in terms of point density corresponding to the relief and vegetation, to compare visual and automated detection of archaeological objects and to verify the results by field survey. The theoretical part describes the principle of laser scanning, its use in archaeology and the application of automated detection approaches to archaeological objects. Furthermore, the development of barrow burials from the Eneolithic to the Middle Ages is outlined and the area of interest is described in detail. The mound burial site at Stradonice is divided into two parts located not far from each other, which are probably not very closely related. In one part there are both rectangular barrows placed in rows and circular ones which occur irregularly around them as if they were of a different age. In the other part, there are only mounds with a circular plan, and some of them are arranged regularly. In the practical part, three sets of point clouds were processed, two of their own from UAVs and one from an aircraft provided by the ČÚZK. Vegetation was...
