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 and a second collection of 3D coordinates of points from a second registration position. In between these positions, the 3D scanner collects 2D camera images. A processor determines first and second translation values and a first rotation value based on the 2D camera images. The processor adjusts the second collection of points relative to the first collection of points based at least in part on the first and second translation values and the first rotation value. The processor identifies a correspondence among registration targets in the first and second collection of 3D coordinates, and uses this correspondence to further adjust the relative position and orientation of the first and second collection of 3D coordinates.

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 and a second collection of 3D coordinates of points from a second registration position. In between these positions, the 3D measuring device collects depth-camera images.

The processor identifies a correspondence among registration targets in the first and second collection of 3D coordinates based at least in part on the first and second translation values and the first rotation value. The processor uses this correspondence and the first and second collection of 3D coordinates to determine 3D coordinates of a registered 3D collection of points.

Abstract: Measuring a volume of space including providing a laser scanner having a transmitter, a receiver, a beam steering mechanism, and a display unit integral to the laser scanner. A plurality of distances to measuring points are determined based at least in part on propagation times of measuring beams sent from the beam steering mechanism and reflected beams. Gray-scale values representative of the measuring points are determined and assigned to elements of a measuring point array, and the measuring point array is transformed into a display point array that corresponds to a first number of display points. The measuring point array corresponds to a second number of measuring points greater than the first number. The transforming includes assigning display gray-scale values to elements of the display point array. For each display point, a pixel of the display unit is illuminated, with the level of illumination depending on the display gray-scale value.
