A Circle-shape is an important figure in most small rule mechanical parts, and usually be measured to get the radius or used as a stand calibration mark. In this paper, a 2-D circle measurement system for small rule mechanical parts based on machine vision is designed and built. The basic components and work principle of the machine vision measurement system are introduced, and the measurement produce is designed and discussed. An available algorithm for circle contour detected and fitted is described. Using this algorithm, the measurement software flow and architecture are built and the software system realized in the Microsoft visual studio program platform. Certainly, the calibration of machine vision system is introduced also. Using the system and method introduced above, an experiment is designed to measure the outer ring radius of one certain model bearing. The measured data is processed and analyzed. Through the experiment and result, it can be found that the measurement system can get relatively high precision and the measurement method is relatively steady, and the system precision and speed can be suit for the demand of on-line and real-time circle measurement.

In recent years, with the research intensity of machine vision in universities are increased ceaselessly, the achievement in machine vision’ field is gradually applied to all walks of life. This paper mainly discusses how the theory of machine vision applied in the practical measurement, and develops the overall measurement platform. Through the program operating in the computer, finally realizes the control of platform operation. It can collect multiple images; what’s more realize image processing and world coordinate calculation, providing a platform for the future research and application.
