摘　　要：针对图像处理技术在产品生产过程中的特点及技术要求,根据LabVIEW的功能特点及其强大的函数库,利用机器视觉技术,以LabVIEW为开发环境,应用视觉开发模块,采用图形化设计思想,为解决人工在检查产品过程中带来的缺陷,设计一种基于LabVIEW的模式匹配方法。实验结果表明,利用该软件实现的产品检测方法运行可靠,易于使用,能够实现模糊和对比度低的图像的匹配检测,提高了匹配性能。According to the characteristics of the image processing technology in the production process and to meet technical re- quirements, based on the feature of LabVIEW and its powerful function library, machine vision technology was applied, in the LabVIEW development environment, visual development module and graphical design ideas were used, and a pattern matching method was designed to solve the defects caused by human in the process of checking product. The experimental results show that the proposed method is operational reliable and easy to use, it can also achieve matching detection on blurring and low con- trast images, improving the matching performance.
