To research the technique of the high speed parallel correlation image tracking device and resolve the problem of tracking the low contrast targets with a complicated background, the parallel processing method was adopted based on the high speed FPGAs, DSPs TMS320C30 and TMS320C50 to realize real time intelligent image tracking. A fast speed correlation algorithm PMSS(probability model step searching) was proposed. The tracking precision of this correlation image tracking device was ±1 pixel, while the processing time of one frame was within only 15 ms. The test showed that the tracking effect was good. This correlation image tracking device is able to resolve the problem of processing speed existing in the current image tracking devices.
