Abstract: A LIDAR system. The LIDAR system includes a light transmitting unit and a light receiving unit. A beam path is formed between the light transmitting unit and the light receiving unit of the LIDAR system, in order to optically scan surroundings of the LIDAR system during the operation of the LIDAR system. The LIDAR system is configured to recognize a contamination of the beam path, based on LIDAR measured data, which have been obtained during the optical scanning of the surroundings. A method for recognizing a contamination of a beam path of a LIDAR system is described, including recognizing the contamination by the LIDAR system based on LIDAR measured data, which have been obtained during an optical scanning of surroundings of the LIDAR system.

Abstract: A method for optically scanning and measuring a scene by a three-dimensional (3D) measurement device in which multiple scans are generated to then be registered in a joint coordinate system of the scene. At first at least one cluster is generated from at least one scan, further scans are registered for test purposes in the coordinate system of the cluster, if specified quality criteria are fulfilled and the generated clusters are then joined, for which purpose clusters are selected, registered for test purposes and registering is confirmed if appropriate, wherein the clusters to be joined are visualized with an optional possibility for the user to intervene, for supporting the selection of clusters.
