摘要：

A new method is proposed to detect circular arcs. The detection of a circular are includes the determination of its center, radius, length, and midpoint. The Hough transform is applied to detect circular arcs by using center and radius as parameters. A peak value in the parameter space of the Hough transform indicates the existence of a circular are. The center and radius of the circular are are given by the coordinates of the peak. The are points are separated from the remaining edge points of the image. Then, the near-peak Hough transform data of the are points is analyzed to determine the are length and midpoint.
