A method for optically scanning and measuring a scene by a laser scanner includes generating multiple scans; tracking scanner positions with a position-tracking device for the multiple scans and providing tracked scanner positions in response; registering sequentially scans selected from the multiple scans into clusters using registration points or targets and confirming registration of the scans into the clusters according to specified quality criteria being fulfilled; selecting scans from the clusters and forming pairs of scans; forming an intersection of the selected pairs and comparing a size of the intersection with a threshold value obtained based at least in part on the tracked scanner positions; and attempting to register the pairs of scans if the size of the intersection exceeds the threshold value and accepting the registered pairs of scans if the registration is successful.

Registering of a scene disintegrating into clusters with position tracking

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, and registering is then confirmed if specified quality criteria are fulfilled and the generated clusters are then joined, for which purpose pairs are formed of selected scans and/or clusters to form pairs, the pairs are registered for test purposes and registering is confirmed if appropriate.
