    Abstract: A system includes a first type of measurement device that captures first 2D images, a second type of measurement device that captures 3D scans. A 3D scan includes a point cloud and a second 2D image. The system also includes processors that register the first 2D images. The method includes accessing the 3D scan that records at least a portion of the surrounding environment that is also captured by a first 2D image. Further, 2D features in the second 2D image are detected, and 3D coordinates from the point cloud are associated to the 2D features. 2D features are also detected in the first 2D image, and matching 2D features from the first 2D image and the second 2D image are identified. A position and orientation of the first 2D image is calculated in a coordinate system of the 3D scan using the matching 2D features.

    Abstract: A system and method for scanning an environment and generating an annotated 2D map is provided. The system includes a 2D scanner having a light source, an image sensor and a first controller. The first controller determines a distance value to at least one of the object points. The system further includes a 360° camera having a movable platform, and a second controller that merges the images acquired by the cameras to generate an image having a 360° view in a horizontal plane. The system also includes processors coupled to the 2D scanner and the 360° camera. The processors are responsive to generate a 2D map of the environment based at least in part on a signal from an operator and the distance value. The processors being further responsive for acquiring a 360° image and integrating it at a location on the 2D map.

    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: 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.
