摘要 针对弹体导带槽宽的工业检测速度和精度要求,采用工业相机、镜头、计算机及专业图像处理软件等搭建了一套机器视觉系统,并依据图像处理算法设计了一个针对弹体导带浅槽宽度测量装置。通过采用标准件对测量系统进行标定,计算出成像系统的标定值,采用两次视觉测量方法分别测量16个弹体导带槽的上下槽宽,进行相应计算得出槽宽值,对这16个工件的实际测量值与三坐标测量结果进行对比试验,其结果表明,该系统的测量精度能够达到微米级,可以满足弹体导带槽宽的测量精度要求,且测量结果不受主观因素的影响。

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.
