摘要
应用IMAQVision将机器视觉技术和虚拟仪器技术相结合,可以快速、准确地进行齿轮在线测量。介绍了基于IMAQVision,应用图像直方图分析和LUT变换、几何变换、边缘检测、亚像素精度、模式匹配等图像处理技术的齿轮几何参数测量方法,分析了其中主要IMAQVision函数的算法。在LabVIEW平台上开发了实用的齿轮测量机器视觉系统。
Using IMAQ Vision, by c ombining machine vision and virtual instrument techniques, can make quickly and accurately online gear measurement. This article presents the technique of gear measurement based on machine vision. Analysis of image histogram, lookup table ( LUT)transformation, geometry transformation, edge detection, sub-pixel accuracy, pattern match, etc. have been used in gear measurement, as well as the algorith m of major functions used in gear measurement is analysed. A practical machine v ision gear measurement system was developed in the LabVIEW environment.
