Abstract：For industrial inspection speed and accuracy requirements of elastomers conduction band width, the use of industrial cameras, lenses, computers and professional image processing software to build a set of machine vision systems and design a elastomer for the conduction band of the shallow groove width measurement device based on the image processing algorithms. Firstly, using the standard part to calibrate measurement system, the calibration values of the imaging system is calculated. Then the two visual measurement method are used to measure the upper and lower groove width of the 16 elastomers conduction band, and the groove width is calculated by corresponding calculation. Finally the actual measured values of the 16 parts and the three coordinate measuring results are compared. The results show that the measurement accuracy of the system can reach to micron level, which can meet the requirements of the measurement accuracy of elastomers conduction band width, and the measurement results are not influenced by the subjective factors.
