摘　　要：描述了一种以TMS3 2 0C670 1数字信号处理器为核心的高速图像处理板和图像实时采集卡及摄像头构成的实时运动跟踪系统。在对采集的实时图像序列进行如干预处理后 ,采用了金字塔结构的图像存储方式和特征点跟踪算法对运动目标进行跟踪 ,通过对特征点的运算得到目标运动的偏差作为摄像头运动的参数 ,最后根据这些参数控制摄像云台持续跟踪运动目标的移动。A real-time motion tracking system made up of high-speed image processing card with TMS320C6701 as the core component, image real-time sampling card and camera is presented. The pretreatments was imposed on the sampled real-time image sequence and the image storage pattern used is of pyramid structure.The feature point_based tracking algorithm is used to track the moving object. The motion error gained from the calculation of the feature points is used as the parameter for the motion of the camera to control the photo platform. The experimenal results under a complicate background are also presented.
