| Research Abstract |
This report describes a new range finding system named Reactive Range Finder, which actively acquires the necessary information according to the kind of vision task. This system can generate a projection pattern that enables an efficient and effective measurement adapted to the change of the scene caused by shape, location and movement of the object. To confirm the efficiency of this system, we made tracking application of polyhedral and cylindrical objects moving with 6 degrees of freedom on this system. In order to determine the position and posture of the object, the Reactive Range Finder selects measurable surface. As the result, the image processing algorithm became simple and easy, and reliable video-rate, say real-time-rate, tracking was achieved without any special-purpose hardware.
