    Abstract: A retroreflective marker assembly. The assembly includes a retroreflective marker and a protective window through which light passes to reflect from the marker. A support structure supports the marker on its face and includes one or more legs, each having a facet that polarizes light upon reflection from the facet. The assembly can include a spherical base with a reflective coating secured to the base. An angular position of the marker with respect to an imaging device is determined by measuring a first angle of a light between the marker and the imaging device along a deviated optical path, determining an angular deviation of the light from a straight-line path, and determining a second angle indicative of the straight-line path based on the first angle and the angular deviation. A polarization angle of light reflected from a facet determines an orientation of the marker with respect to the imaging device.

    Abstract: A method including determining with a three-dimensional (3D) measuring instrument 3D coordinates of an object for each of a plurality of poses of the 3D measuring instrument; capturing with a camera first- and higher-order diffraction components of markers near or on the object, the camera having a diffractive optical element (DOE), a lens, and a photosensitive array; and registering with a processor the determined 3D coordinates based at least in part on the determined 3D coordinates and on the imaged zero- and higher-order diffraction components.

    Abstract: A system and method of determining three-dimensional coordinates is provided. The method includes, with a projector, projecting onto an object a projection pattern that includes collection of object spots. With a first camera, a first image is captured that includes first-image spots. With a second camera, a second image is captured that includes second-image spots. Each first-image spot is divided into first-image spot rows. Each second-image spot is divided into second-image spot rows. Central values are determined for each first-image and second-image spot row. A correspondence is determined among first-image and second-image spot rows, the corresponding first-image and second-image spot rows being a spot-row image pair. Tach spot-row image pair having a corresponding object spot row on the object. Three-dimensional (3D) coordinates of each object spot row are determined on the central values of the corresponding spot-row image pairs. The 3D coordinates of the object spot rows are stored.

    Abstract: An imaging device and method of imaging a region. The imaging device includes a first camera and a first light source set at a periphery of the first camera, a second camera separated from the first camera by a selected distance and a second light source set at a periphery of the second camera, and a processor configured to operate the first light source set and the second light source set independently of each other. The region is illuminated using the first light source and a first image is obtained. The region is illuminated using the second light source and a second image is obtained. At least one of the first image and the second image includes an illumination effect.

    Abstract: An inspection system for measuring an object is provided. The inspection system includes an entryway sized to receive the object. At least two non-contact coordinate measurement devices are positioned with a field of view being at least partially within or adjacent to the entryway, each of the at least two non-contact coordinate measurement devices being operable to measure 3D coordinates for a plurality of points on the object as one of the object or the entryway move from a first position to a final position. A pose measurement device is operable to determine the six-degree of freedom (6DOF) pose of the object. One or more processors are provided that register the 3D coordinates for the plurality of points from each of the at least two non-contact coordinate measurement devices based at least in part on the 6DOF pose of the object.
