摘　　要：研究运动目标PTZ跟踪技术,以HSI加权彩色直方图作为目标模型,通过均值偏移算法实现运动目标的定位。设计自适应波门,通过边缘检测保证核窗宽和模板更新的实时性。根据高速球的云台转动参数,提出自动变焦跟踪算法,实现目标跟踪过程中的自动镜头缩放,由此提高跟踪稳定性。最后搭建系统,验证整个算法的可行性。Research moving object PTZ tracking technology, target Orientation has been implemented through mean-shift based on weighted color histogram. Designed adaptive gate to assured real-time capability of kernel-bandwidth and mode by edge detecting. According to the rotating parameter of high speed ball, put forward auto zoom tracing algorithm to accomplish auto lens changing in object tracing process, thereby improved its stability. At last, the system has been built to prove the feasibility of algorithm.
