摘要
从图像处理的角度出发,介绍了求取圆和椭圆特征参数的算法——最小二乘拟合法。对圆形零件特征的计算,还提出了面积法和周长法。通过对计算结果的比较,得到拟合圆和面积法是比较有效的计算方法。
In the image processing, the algorithm for characteristic parameters of circle and ellipse can be evaluated by means of least square fitting. Besides, the algorithm of characters of circular sections can also be realized by the area method and perimeter method. The comparison of the results show that the least square circle and area method are effective ways.
