In geodesy, mandatory regulations on standardized specifications of terrestrial laserscanners’ performance features are still missing which would allow an objective comparability of different scanner models. In this paper feasibly realizable testing series are presented, which will support such comparability using objective criteria. Basic concept especially is a relevant question for users concerning the quality of a TLS-generated 3D point cloud at plane surfaces and edges as a function of the chosen scanning filter setup. The comparison concept is applied using three up-to-date TLS systems (Faro Focus3D, Leica HDS7000 and Leica Scanstation P20) and results are presented. One particular intent is to show a set of test arrangements for practical use to obtain system independent benchmarks describing quality features rather than using the pure manufacturers’ technical data specifications. Furthermore at the beginning an overview on an existing TLS standard testing procedure is given.     «
