Dynamic Tracking performance is an important technical index for system appraisal. In view of the reality such as the shooting range target detection system facing small target, long distance, complicated background etc, It designs a dynamic tracking precision evaluating system, which detects tracking accuracy and stability degree by means of calculation the target's relative motion and coordinate transformation. Positions the target's cross center rapidly by using image segmentation, object extraction and other image processing algorithms, calculates the center's offset, obtains the device's tracking error by coordinate transformation, and implements algorithms in DSP (Digital Signal Processing) and FPGA (Field Programmable Gate Array) to ensure the system's light-weight and small-sized. Experimental results show that the system can detect and evaluate the efficiency and precision of dynamic tracking system in complex environment.
