摘　　要：针对当前光电跟踪系统在复杂背景下对目标跟丢的情况,设计了一款应用在交通执法领域且适用于复杂背景的光电跟踪系统。该系统采用Hi3516A处理器完成对视频图像的获取、处理,保存成H.264或H.265码流文件,通过无线WIFI和实时流传输协议RTSP(Real Time Streaming Protocol)将码流文件实时传输到PC端进行显示;同时,应用模糊系统对KCF跟踪算法进行改进,实现滤波模型的自适应更新。此外,该系统基于GD32F407处理器采用PD控制算法实现俯仰和航向双自由度的控制,使目标始终保持在视野的中心。实验结果表明,应用改进后的跟踪算法使得该系统能够完成在复杂背景下对目标的准确跟踪,且运行速度在每秒30帧左右。A photoelectric tracking system applied in the field of traffic law enforcement is designed to solve the problem of failure of tracking target in challenging scenes.Hi3516A processor is used to complete the acquisition and processing of video images,which are saved as H.264 or H.265 stream files.The stream files are transmitted to the PC for display through wireless WIFI and RTSP(Real Time Streaming Protocol)in real time.At the same time,fuzzy system is applied to improve the KCF tracking algorithm to adaptively up-date the filter model.In addition,based on the GD32F407 processor,PD control algorithm is used to achieve pitch and heading control with two degrees of freedom.Therefore,the target is always in the center of the image captured by camera.The experimental results show that the improved tracking algorithm enables to accurately track the target in challenging scenes,and the running speed is about 30 frames per second.
