摘　　要：文章讨论和研究了基于图像的定位技术原理,根据对得到近似为圆形的目标图像的特征分析,提出了一种新的边缘检测方法,介绍了具体的边缘检测方法、灰度插值方法和中心计算方法的实现,并将其用于闭环控制系统中,仿真实验表明,图像处理过程达到了不大于0 02像素的偏差,能够完成要求的定位精度(0 1像素)。The principle of orientation technique based on image processing is discussed. A new edge detection method is proposed, and the practical implementation of edge detection, gray-level interpolation, and center calculation are introduced, which are applied in a closed loop control system. It has been verified by simulation that the aim for precise orientation can be implemented, and the maximum error is less than 002 pixel during the procedure of image processing.
