Abstract: A method and system of generating a two-dimensional map with an optical scanner is provided. The method comprises acquiring coordinate data of points in an area being scanned with a mobile optical scanner. A current 2D map from the coordinate data is generated. A copy of the current 2D map is saved on a periodic or aperiodic basis. At least one data registration error is identified in the current 2D map. The saved copy of the current 2D map from a point in time prior to the registration error is determined. A second data set of coordinate data acquired after the determined saved copy is identified. The second data set is aligned to the determined saved copy to form a new current 2D map. The new current 2D map is stored in memory.

Abstract: A method and system for generating a three-dimensional (3D) map of an environment is provided. An example method includes receiving, by a processor system, via a 3D scanner, located at a scan position, a 3D scan of the environment. The method further includes receiving via a two-dimensional (2D) scanner accessory, a portion of a 2d map of the environment. The method further includes receiving coordinates of the scan position in the 2d map in response to the 3D scanner initiating the acquisition of the 3D scan. The method further includes associating the coordinates of the scan position with the portion of the 2D map. The method further includes determining a displacement vector for the 2D map using a loop closure algorithm. The method further includes computing a revised scan position based on the scan position and the displacement vector, where the 3D scan is registered using the revised scan position.

Abstract: A laser scanner and method of operation to determine the consistency of a registration is provided. The method includes generating with the laser scanner at least a first scan of the scene with first measuring points. The laser scanner generates at least one second scan of the scene with second measuring points. At least one measured distance is determined from at least one of the second measuring points to the center of the second scan. The second scan is provisionally registered subjected to a consistency check. The consistency check is performed. At least one virtual distance is determined from at least one of the first measuring points to the center of the second scan. The consistency check is based at least in part on comparing the at least one virtual distance with the at least one measured distance.

Abstract: 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.
