Laser-based Tracking

Smart Laser-Scanner for 3D Human-Machine Interface Alvaro Cassinelli, Stephane Perrin, Masatoshi Ishikawa, University of Tokyo, Japan The problem of tracking hands and fingers on natural scenes has received much attention using passive acquisition vision systems and computationally intense image processing. We are currently studying a simple active tracking system using a laser diode, steering mirrors, and a single non-imaging detector, which is capable of acquiring three dimensional coordinates in real time without the need of any image processing at all. Essentially, it is a smart rangefinder scanner that instead of continuously scanning over the full field of view restricts its scanning area, on the basis of a real-time analysis of the backscattered signal, to a very narrow window precisely the size of the target. The complexity of the whole setup is equivalent to that of a portable laser-based barcode reader, making the system compatible with wearable computers.
