基于CamShift的跟踪系统的设计

介绍了一套目标跟踪系统。上位机采用基于CamShift算法，利用目标的颜色直方图模型得到每帧图像的颜色投影图，并根据上一帧得到的结果自适应调整搜索窗口的位置和大小，得到当前图像中目标的尺寸和中心位置，然后计算中心位置距离图像中心的偏移量；下位机是利用DSP设计的一套运动控制系统，由自主研发的DSP型伺服放大器、直流伺服电机和云台、伺服驱动单元组成，能够根据运动偏差控制云台跟踪运动目标的移动。实验证明：本系统可以较好地实现简单背景下物体的跟踪。

A Tracking System Design Based on CamShift

Introduces a target tracking system.The host PC adopts CamShift arithmetic,CamShift operates on a back-projection image produced from object histogram model,computed information is used previously to adjust current search window size and location,the location and size of the color object are found.Then calculate displacement from the picture central.The target PC is that use DSP to design motion control system,it includes DSP servo amplifier which was designed independently,DC servomotor and turntable,servodrive unit,could use the warp to control the platform track target object.Experiments prove:the system can implement object tracking of simple background.
