Two-dimensional image processing method and apparatus for approximating circular arc configuration of an object |
摘要 |
Two-dimensional image data of an object is processed to inspect a circular arc configuration of the object. Initially, the two-dimensional image data is subjected to a data extraction process in which image edge points of the circular arc configuration of the object are extracted from the two-dimensional image data. The image edge points are then applied to a process to approximate the circular arc configuration of the object by defining a circle which minimizes a mean value of a fourth power error of the image edge points relative to the circle, the thus defined circle being used to approximate the circular arc configuration of the object.
