Abstract
To observe multiple scenes in completely different views, we developed a galvano-mirror-based multithread active vision system that can determine its view direction frame by frame at 500 fps. On the active vision system, multiple pan-tilt-camera control processes can be multithread as 2 ms time-slicing processes; our system can metamorphose into two virtual pan-tilt cameras at 250 fps and twenty-five virtual pan-tilt cameras at 20 fps. Several experimental results demonstrate the effectiveness of virtual pan-tilt cameras control for video tracking and recording of multiple moving scenes without using multiple cameras.
