Then, two methods are discussed which are point-circle transformation and circular curve fitting for inspecting the bearing's circularity, dimension and concentricity.
然后，着重讨论了用于轴承边界的圆度、尺寸和圆心度检测的两种计算方法—点—圆变换法和圆形曲线拟合法。

Point, line, circle, polygon and Interpolation curve programming.
可以编制点、线、圆、圆弧、多边形、多点拟合曲线。

This paper has proved that a plane curve cis a circle if and only ifc is the locus of a moving point that has a constant second power average of distances from n fixed points.
