：自准直仪是比较常用的测角仪器，其原理是检测激光形成的图像光斑的中心之间的距离，通过 ) 个中 心的横纵坐标差来计算物体偏离的角度 ’ 利用迭代阈值和图像分割等方法将光斑图像进行预处理，然后将得到 的图像分别用重心法、圆拟合法和匹配法进行中心定位，并最终进行偏离角度的测定 ’ 文中介绍了所使用的几 种方法，并进行了仿真比较，结果表明，圆拟合法更有优势 ’ (: Is more commonly used since the collimator angle measuring instrument, the principle is to detect the distance between the center of the laser spot image formed by a) a horizontal and vertical coordinates of the center differential to calculate the deviation angle of the object ' iterative threshold and image method of segmentation, such as the spot image preprocessing, and then the resulting image with the center of gravity method, respectively, round contemplated legitimate and matching method center position, and eventually for the Determination of the deviation angle of ' paper describes the use of several methods, and simulation comparison, the results show that the circle fitting more advantageous' )
