  • Stereoscopic calibration using a multi-planar calibration target
    Patent number: 10666925
    Abstract: A system of calibrating a multi-camera device that include two or more planar calibration targets, arranged in a non-planar orientation. The system mechanically moves the calibration targets relative to the multi-camera device to change the relative orientation. The system records images with the multi-camera device at various orientations. The recorded images contain one or more of the constituent planar calibration targets. The system identifies and extracts the pixel coordinates of each constituent planar calibration target from each image.
