Real time object tracking with a low-cost smart camera

چکیده
Reliable object tracking at video speed is a task that requires high performance. We have analyzed the various parts of typical algorithms and found that some parts of program flows are best performed on a parallel platform for performance reasons and other parts are better performed on a sequential processor for reliability and versatility reasons. Combining the two processing profiles in one platform gives the best of both worlds and enables real time, reliable performance. To prove this concept, we have designed and built a programmable architecture consisting of a massive parallel pixel processor and a sequential DSP. On this platform we mapped the challenging task of high speed object tracking. It was found that offloading the pixel intensive tasks to the parallel processor gives ample processing power to make reliable vision decisions and environment control on the sequential processor. Good results are demonstrated for robot based soccer playing in the RoboCup environment.
