Paper Abstract

This paper describes an algorithm which recovers 6 degrees of freedom ( that is rotational and translational matrices R and T ) of polyhedral objects using L-corners in a monocular image. First the gradients of the cirtain object''s faces are determined using the constraints derived from angles of L-corners. R accompanied by the object is then determined. Second a constraint concerning T is derived from a junction point of a Lcorner. After that T is determined using a set of constraints derived from the L-corners that contributed to the determination of R. By assembling only those L-corners the cirtain object is recognized.
