Real-Time Vision System Based on Correlation Processing.

摘要

This paper describes a high-performance robot vision system that performs real-time tracking of moving objects and real-time optical flow computation. The system is implemented as a transputer-based vision system augmented with a high-speed correlation processor. The vision unit is equipped with three image frame memories, each of which can be used simultaneously for image input, image processing, and image display. Thus, the system can devote all its computation power to image processing without waiting for image input or image display. The vision board is also equipped with a correlation processor. Using the chip, we have developed a very fast correlation based robot vision system. This system can also be used as multi-processor configuration to greatly increase performance.
