    Abstract: A 3D measurement device sends a beam of light to a point on an object, receives the reflected light, and determines a distance and two angles to the point, one of the angles measured by an angular encoder, which includes a disk having incremental marks and an index mark. Light from the 3D device is rotated to reflect light from a reference reflector to produce a first synchronization signal. A first difference angle is determined based on counts of the incremental marks and on the first synchronization signal. Light from the 3D device is rotated to reflect light from the reference reflector to produce a second synchronization signal. A second difference angle is determined based on counts of the incremental marks and on the second synchronization signal. The reference correction value of the index mark is determined based on the first and second difference angles.

    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.

    Abstract: A device for scanning and obtaining three-dimensional coordinates is provided. The device may be a hand-held scanner that includes a carrying structure having a front and reverse side, the carrying structure having a first arm, a second arm and a third arm arranged in a T-shape or a Y-shape. A housing is coupled to the reverse side, a handle is positioned opposite the carrying structure, the housing and carrying structure defining an interior space. At least one projector is configured to project at least one pattern on an object, the projector being positioned within the interior space and oriented to project the at least one pattern from the front side. At least two cameras are provided spaced apart from each other, the cameras being configured to record images of the object. The cameras and projector are spaced apart from each other by a pre-determined distance.
