ABSTRACT:
A sensing system for accurately monitoring the position and orientation of an object (28). At least 4 point light sources (26) are mounted on the surface of the object (28). A single electronic camera (20) captures images (92) of the point light sources (26). Locations of these images (92) are detected in each camera image, and a computer runs an iterative task using these locations to obtain accurate estimates of the pose of the object (28) in a camera coordinate system (90) at video rate. The object is held by an operator (40) for cursor (60) control, for interaction with virtual reality scenes on computer displays (22), or for remote interactive control of teleoperated mechanisms.
