Patent number: 8437537Abstract: A method estimates a 3D pose of a 3D specular object in an environment. In a preprocessing step, a set of pairs of 2D reference images are generated using a 3D model of the object, and a set of poses of the object, wherein each pair of reference images is associated with one of the poses. Then, a pair of 2D input images are acquired of the object. A rough 3D pose of the object is estimated by comparing features in the pair of 2D input images and the features in each pair of 2D reference images using a rough cost function. The rough estimate is optionally refined using a fine cost function.Type: GrantFiled: July 27, 2009Date of Patent: May 7, 2013Assignee: Mitsubishi Electric Research Laboratories, Inc.Inventors: Ju Yong Chang, Amit Kumar Agrawal, Ashok N.
