Stable Tracking Control of Puny Target in Complicated Background

复杂背景下弱小目标的稳定跟踪控制,利用自适应阈值跟踪波门和鼠标导引来实现。该控制通过电视/红外成像和激光测距以及视频处理技术,结合编码器测量角度值,得到目标偏离视场中心的偏差值,然后将偏差值作为负反馈送给光电跟踪伺服,驱动转台朝着减小偏差量的方向转动,从而实现对目标的稳定跟踪。

The stable tracking control of puny target in complicated is realized by utilizing the tracking window of adaptive threshold value function and mouse guide function. After processing of TV/infrared imaging and laser telemeter, as well as video technology, and combining with the angle value of encoder, the bias value of the puny target deviating from the central of visual filed was obtained by the system. And then, the bias value was used as negative feedback to the photoelectric tracking servomechanism and drive the swivel table to run along the direction of decreasing the bias value, consequently, the stable tracking control of puny target in complicated was achieved.
