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 for measuring and registering 3D coordinates has a 3D scanner measure a first collection of 3D coordinates of points from a first registration position. A 2D scanner collects horizontal 2D scan sets as 3D measuring device moves from first to second registration positions. A processor determines first and second translation values and a first rotation value based on collected 2D scan sets. 3D scanner measures a second collection of 3D coordinates of points from second registration position. Processor adjusts second collection of points relative to first collection of points based at least in part on first and second translation values and first rotation value. Processor identifies a correspondence among registration targets in first and second collection of 3D coordinates, and uses this correspondence to further adjust the relative position and orientation of first and second collection of 3D coordinates.
