摘要:
研究了运动目标检测与跟踪的DSP（Digital Signal Processor）实现算法，以形心跟踪算法为整个处理系统的核心。采用目标形心跟踪算法，通过目标分割阶段的目标标记，如目标面积、周长、形心位置等信息的提取建立目标跟踪波门，实现目标的连续跟踪，并将此算法移植到sEED—VPM642硬件平台，实验结果表明能够达到预定目标。此外，为了克服形心算法的准确性和实时性缺陷，采用粒子滤波对算法进行必要的扩展，从MATLAB的仿真结果看，除个别采样点存在误差较大的情况，真实值曲线与粒子滤波跟踪曲线拟合较好
Abstract:
Study the DSP （Digital Signal Processor） algorithm for detecting and tracking moving target, with the centroid tracking algorithm as the core of the whole processing system. By marking the target segmentation stages,such as area,perimeter,centroid position information extraction,the target centroid tracking algorithm can construct the target tracking gate to achieve the goal of continuous tracking. Transplanting this target centroid tracking algorithm into the SEED-VPM642 hardware platform,the experimental results indicate that the predetermined target can be achieved. In addition, necessary expansion of the particle filter algorithm can be used to overcome the centroid algorithm accuracy and real-time defect. The MATLAB simulation results show that the true value curve fits for the particle filter tracking curve to much extent,except that a few sampling points differ much from the others
