Sekundarni naslov:	Object-based classification of photogrammetrically acquired point cloud
Sekundarni povzetek:	This graduation thesis addresses unmanned aerial vehicle for aerial data acquisition - quadrocopter. Data (point cloud), acquired with the vehicle is presented and object-based classification of this point cloud is performed. The thesis describes methodology of data preparation with free open source software SAGA and classification of point cloud in free open source software InterImage. Protocol of producing different data layers from the point cloud is tested and the influence of input data on the segmentation quality is presented. We focused on finding appropriate parameters for classification and studied their impact on classification results based on histogram analysis. We used the knowledge of parameter selections obtained from one point cloud and applied it to another point cloud that represented similar area. We discovered that the classification with the same parameters can be repeated only for certain object classes. For sufficient classification of all object classes new parameter settings are required.
