Patent number: 7231087Abstract: A method for approximating an object's pose from a camera generated image of a scene is performed by first extracting a binary map from the image. The binary map is filtered to include silhouettes of objects located within a predetermined range of distances from the camera. An initial binary shape template may be applied to the binary map to locate potential target object silhouettes. Iterative stages of binary templates are applied to the each target object silhouette that represent a range of poses of the target object. Each stage of templates has higher spatial fidelity than the previous stage and poses corresponding to templates that do not sufficiently match the silhouette are eliminated from consideration. The target object's pose is approximated based on a set of templates that best matches the target object silhouette.Type: GrantFiled: October 29, 2003Date of Patent: June 12, 2007Assignee: Metrica, Inc.Inventor: Eric Huber

Patent number: 6595704Abstract: A two degree of freedom camera mount. The camera mount includes a socket, a ball, a first linkage and a second linkage. The socket includes an interior surface and an opening. The ball is positioned within an interior of the socket. The ball includes a coupling point for rotating the ball relative to the socket and an aperture for mounting a camera. The first and second linkages are rotatably connected to the socket and slidably connected to the coupling point of the ball. Rotation of the linkages with respect to the socket causes the ball to rotate with respect to the socket.Type: GrantFiled: April 6, 2001Date of Patent: July 22, 2003Assignee: Metrica, Inc.Inventor: Robert O. Ambrose

Patent number: 6543307Abstract: A robot having a plurality of interconnected sections is disclosed. Each of the sections includes components which are moveable relative to components of an adjacent section. A plurality of electric motors are operably connected to at least two of said relatively moveable components to effect relative movement. A fitted, removable protective covering surrounds the sections to protect the robot.Type: GrantFiled: April 6, 2001Date of Patent: April 8, 2003Assignee: Metrica, Inc.Inventor: Robert O. Ambrose
