  • Method and system for determining poses of semi-specular objects
    Patent number: 8107721
    Abstract: A camera acquires a set of coded images and a set of flash images of a semi-specular object. The coded images are acquired while scanning the object with a laser beam pattern, and the flash images are acquired while illuminating the object with a set of light sources at different locations near the camera, there being one flash image for each light source. 3D coordinates of points on the surface of the object are determined from the set of coded images, and 2D silhouettes of the object are determined from shadows cast in the set of flash images. Surface normals are obtained for the 3D points from photometric stereo on the set of flash images. The 3D coordinates, 2D silhouettes and surface normals are compared with a known 3D model of the object to determine the pose of the object.
