The model of a family house in Revit
Soukup, Štěpán ; Hanzl, Vlastimil (referee) ; Berková, Alena (advisor)
This diploma thesis focuses on processing and data collecting for the use of creating functional 3D informating model that we call BIM (Building Information Modelling) which is getting more and more attention throughout building industry and it is used by all of the participants in the industry from designers and architects to those who are dealing with building installations. This process is slowly getting into legislations of many countries including Czechia. The thesis is divided into two parts where one of them is describing the Building Information Modeling in general and the other part is describing the work which is behind the colleting good data which is needed when making the 3D documentation in Revit software which is wildly used for designing building constructions. Practical part of the land surveyor´s work is devided here into two parts where one of them is dedicated to collecting data by laser scanning process, GNSS and measuring by total station and levelling machine. Second part focuses on the description of the data processing in order to make 3D model. The example of the output production data is the BIM 3D model of the family house in selected level of detail and besides that we also have the visualization of both interior and exterior and 2D simplified building documentations.

IMPROVEMENT OF DIGITAL MODEL BY LASER SCANNING METHODS
Tyagur, Nataliya ; Václav, Šafář (referee) ; Hana, Staňková (referee) ; Bartoněk, Dalibor (referee) ; Hanzl, Vlastimil (advisor)
The doctoral thesis deals with mobile laser scanning and data processing. Mobile laser scanning was carried out in the Moravian Karst in Suchy zleb and Pusty zleb at various seasons. Further scanning was carried out at the Training Forest Enterprise Masaryk Forest Křtiny. The Riegl VMX-450 scanner was used to collect 3D data. The data files were processed in the OPALS software. For the extraction of ground and non-ground points from the laser cloud, a combination of hierarchical interpolation and robust filtering was used. Subsequently, the terrain points were used to model digital terrain models with grids 0.05 x 0.05 m, 0.25 x 0.25 m, 1 x 1 m. Furthermore, digital models from Moravian Karst were compared with the Digital relief model of the Czech Republic 4G and reference points. Digital models from Masaryk Forest Křtiny were compared with photogrammetric and terrestrial data. The high accuracy of the derived DTMs is about 0.10 m. The high quality of the derived DTM can be used to monitor and analyze field changes and morphological structures.

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.

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.

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.
