halcon-轮廓拟合圆fit_circle_contour_xld fit_circle_contour_xld (xld,'algebraic', -1,0,0,3,2, Row, Column, Radius, StartPhi, EndPhi, PointOrder)*对XLD轮廓做近似圆计算--拟合圆--获得圆数据*参数1:输入xld轮廓*参数2:圆的拟合算法*'ahuber'对轮廓点进行加权,以减少异常值的影响*'algebraic'这...
halcon中fit_circle_contour_xld算子同样集成了几何拟合与代数拟合,并引入权重函数(huber和tukey),tukey直接去除异常点,huber削减异常点的影响,所有内点到拟合圆的距离标准差被用来评估拟合过程的好坏。我没有完全按照halcon中的去实现,而是随机选择至少三点拟合圆,评估误差和内点数量,迭代过程结束后选取误差最小或内点数...
fit_circle_contour_xld用圆拟合XLD轮廓。它不执行输入轮廓的分割。因此，必须确保每个轮廓对应一个且仅...

fit_circle_contour_xldapproximates the XLD contoursContoursby circles. It does not perform a segmentation of the input contours. Thus, one has to make sure that each contour corresponds to one and only one circle. The operator returns for each contour the center (Row,Column), and theRadius....
