Abstract :
To realize the online automatic measure the parameter of seals inner and outer diameter, the measure technology base on machine vision was researched; the main parts of measure system were introduced. To solve the problem that the lightness of light source is deficient, which affects the result of image disposing in machine vision system, it leads to measure precision low. According to the theory of photometry, the ring light source that is composed of many LED was designed, and the luminosity of LED was calculated and analyzed; the control circuit on light source brightness was designed and analyzed, the relative parameter was calculated in circuit. Through experiment, the designed light resource can meet the need, the image that camera gather is very clear, which is favor to image disposing and analysis. The result shows that the designed measure is feasible, and the measure precision has obvious increased.
