摘　　要：描述一种使用高速图像处理器和摄像头进行运动目标实时跟踪的系统 .图像处理器的核心由一块TMS32 0C6 70 1数字信号处理板及图像实时采集卡构成 .在对采集的初始图像序列作若干预处理后 ,采用改进的加约束的光流场算法从复杂背景中快速地计算出光流场 .根据运动目标的形状特征 ,较为完整地提取出运动目标区域 ,并计算目标运动的速度大小和方向 ,最后根据这些参数控制摄像云台机构持续跟踪移动的目标 .文中还给出在复杂背景下跟踪人物的实验结果 .Describes a real-time moving object tracking system using a high-speed image processor and a camera head. The image processor is composed of one digital signal processing (TMS320C6701) board and a real-time image input card. After preprocessing the original image sequences firstly, we then extract the optical flows regions of the moving object from multiple scenes by using the improved method of optical flows algorithm, then, the region of the moving object on the image is extracted from the optical flows using knowledge about the shape of the moving object. Finally, the camera head is controlled to keep the moving object in the field of view of the camera. The result is shown for tracking a person in a cluttered background.
