Sekundarni povzetek:	The purpose of this graduation thesis is to develop an algorithm to automatically acquire positions of buildings or objects on a topographic map and assign found objects their boundary lines. The thesis first presents some established methods for image processing and analysis. The presented methods are: • use of convolution masks for picture filtering • use of the Sobel operator for edge detection • derivation for gradient checking • linear Hough transform This is followed by the description of an algorithm that uses the aforementioned methods to find approximate positions of all objects and assign each object their boundary lines. The output of the algorithm is a set of polygons that represent, with their shape and position, buildings on the topographic map. The results can be represented in a 3D environment with some additional processing. The described and implemented algorithm works well but still has a lot of room for improvement.
