Abstract :
We have developed a 1 ms vision system, to provide a much faster frame rate than that of the conventional systems. Our 1 ms vision system has a 128×128 PD array and an all parallel processor array connected to each other in a column parallel architecture, so that the bottleneck of an image transfer is solved. 1 ms visual feedback has been realized in this system, in which the image feature value is extracted in 1 ms cycle-time for visual servoing. We have also developed a high speed active vision system (AVS)-II. Finally, we provide a detail discussion on our 1 ms vision system and its performance through some experiments
