An omnidirectional sensor for fast tracking for mobile robots.

We present an omnidirectional vision system we have implemented to provide our mobile robot Rullit with a fast tracking capability. Rullit has to recognize elements in a semi-structured environment (the soccer field of Robocup) at a rate close to 20 Hz. We have designed a multi-shaped mirror to optimize the resolution of the image and its coverage. The interpretation system is based on focused, multi-level, and opportunistic procedure
