近几年机器视觉技术在国内外已经取得了比较好发展，并且广泛应用于工农业生产领域。针对机器人视觉系统进行全过程的研究，通过安装在机器人上的摄像头来采集一组图像序列，通过图像系统精确地检测出实时运动的物体并进行瞬时跟踪。研究几组对阈值距离不超过0．5 m的图像进行二值化处理，然后进行时间差分。最后采用激光通信这种现代控制理论和最优控制算法提高目标检测与跟踪精度。结果表明，通过对比激光通信这种算法，稳定性高，精度好，耗时短。%In recent years machine vision technology has made great development both at home and abroad, and is widely used in industrial agriculturial production . The article researched on the whole process of the Navigation roboe vision system, through the camrea installde on the robot gatherde a grouo of image se-quence. The image system accurately detect instantaneous tracking and rean-time motion object. Research groups of images of the threshold distance is less than 0. 5m, binarization processing, then the time differ-ence. Finally using laser communication the morden control theory and optimal control algorith improve the target detection and tracking accuracy . Resluts show than this laser communication algorithm is of high sta-bility, good precision, time is short.
