用边缘检测算法检测的圆的像的边缘点，并用多元线性回归求出椭圆的方程，然后按照我们的模型中提供的方法，求出每个圆心的像的位置-Using edge detection algorithm to detect the edge of the image circle points, and multiple linear regression equation of the ellipse obtained, and then follow

根据圆弧上多点的实测数据，拟合计算圆心坐标和圆的半径(According to the measured data of multiple points on the arc, the coordinates of the center of the circle and the radius of the circle are calculated and fitted.)
