3 October 1995Automatic measurement of pinion-type gear profile using computer vision
A new method of automatic measurement of a pinion type gear's profile using computer vision is provided and the measurement principle is analyzed. Based on a tool maker's microscope, a CCD camera, a real-time image sampling board, and a computer a vision system is established. Through calibration, edge detection, and detection of pinion gear center two kinds of modes, i.e., centering measurement and non-centering measurement of profile error, are realized by special software. A new operator is provided to find the edge of the binary digital image and the results of edge detection by the operator are presented. Block gauge method is used in system calibration and the results show that the system resolution will reach 3.28 micrometer/pixel (horizontal) and 1.60 micrometer/pixel (vertical) if the 5 (Chi) objective is used. The measurement results of an involute pinion type gear's profile error is also given in the paper.
