Design of Pravčická brána 3D model and its integration with 2.5D TIN terrain model
 Brýdl, Ivo ; Brůha, Lukáš (advisor) ; Lysák, Jakub (referee)
The main goal of this thesis is to design integrated model containing a three-dimensional representation of Pravčická brána rock arch and 2.5D TIN model of surrounding terrain. Point cloud from airborne lidar measurements has to be classified into ground and non-ground features. The ground points are the basis of the TIN terrain representation. Second part of this thesis is focused on methods for reconstructing 3D surface from given points set retrieved with ground-based lidar measurement. The thesis describes the process of meshing point cloud with Poisson surface reconstruction. Finally, these two models are oriented and translated to real coordinates in order to form integrated hybrid model covering part of České Švýcarsko National Park.

Automatic generalization of 3D building models
 Brýdl, Ivo ; Brůha, Lukáš (advisor) ; Bayer, Tomáš (referee)
The main aim of this thesis is to propose a novel method for generalization of 3D building models with respect to topology in 3D space. The first part gives an overview over spatial data structures and methods for generalization of 3D objects. The second part presents the methodology composed of volumetric mo- del reconstruction, topology validation and simplification of geometry based on mathematical morphology approach to build multi scale model. Method is then implemented and experimental results are presented. In conclusion results are discussed and possible improvements are suggested.
