GRADIENT REFLECTOR LOCATION SENSING SYSTEM |
摘要 |
A multi-band high-speed videometric head tracking system (10) having a gradient reflector array (12) attached to a helmet (13) on a person's head, ultraviolet light source (14) emitting light which is reflected by the reflector array to a video camera (11) which provides an image to a spot location estimator (29) providing accurate locations of spots in the image representing the reflectors' reflecting light to image location accuracies within a pixel of the image. The location information from the spot location estimator goes to a track point 3-D location and helmet LOS estimator (33) that provides location and orientation information to a Kalmam Filter (15) that accurately estimates and predicts the helmet position at faster rates than would be possible for a process that uses just the image-based measurements of the helmet.
