This paper focus on dimension detection of mechanical parts and feasibility of non-contact measuring.Realize edge,mounting and location holes detection base on regular HOUGH transform.Through the method is introduced in this article can solve linear edge detection without Interference of discrete points,short segment and collinear un-link points.Also realize hole edge detection without Interference between holes.Through the experiment with the needle sewing on the board,this method can detect the needle plate long straight edges of rectangular hole and contour line and eliminate interference.This method also can detect needle plate on the edge of the hole and the outline of the needle plate.
