摘　　要：在摄影测量中,采用人工编码点可以实现多幅图像中标志点之间的自动匹配。提出一种对环状编码点的自动检测方法,实现编码点的提取以及编码环带的解码。实验结果表明,相机轴线与编码点平面法线夹角在60°以内时,使用这种方法能够实现对编码点的准确解码。In photogrammetry,automatic matching of marked points during multiple images could be achieved by using the encoded point.A method of automatic detection to circular encoded point has been presented.And this method could extract the encoded point from the picture and decode the circular area of the point.Through the experiment find this algorithm could decode the encoded point with no error when the angle between camera axis and the normal line of the plane of the encoded point is less than 60 degree.
