Kompaktes Sensorsystem zur optischen Bewegungserkennung in Echtzeit

摘要

Optical motion detection can be achieved by calculating the optical flow as the motion field resulting from processing an image sequence according to a predetermined algorithm. The existing systems in this area are either very large or have an extremely parallel way of operating, and are only capable of low image resolution and low processing speed. The inventive compact sensor system (1) has a special digital image processing computer architecture in the form of a consistent pipeline structure with data feedback (6). The maximum data throughput necessary for fulfilling the real time condition is achieved by virtue of the fact that the image points are read fully sequentially and the optical flow values are calculated and written simultaneously. There are a variety of possible applications for the sensor system, these being wherever regulating and control processes need to be carried out by means of observing a movement, for example where several moving objects in one area need to be navigated and prevented from colliding.
