Paper Abstract

The measurement method of mechanical part based on computer vision is a new trend with high accuracy, high speed and automation, which plays a very important role in machining industry. In this paper, a new measurement method of circular hole of mechanical part is proposed based on the subpixel-precise thresholding and contour extraction. Under the base of the new measurement method, a computer vision system is designed to measure the position of hole, diameter of hole, circularity of hole, and the distance between relevant two holes with high speed, high efficiency and subpixel-precise. Good results have been got in the measurement experiment, which proves the validity of the new measurement method.
