摘　　要：为实现基于机器视觉的螺栓开口销防差错,设计了差错诊断程序架构,借助Vision Assistant搭建了图像采集、图像灰度处理、差错诊断脚本功能块,介绍了模式匹配、坐标系的配置及差错诊断检测流程。并在LabVIEW编程环境中采用NI Vision Builder和IMAQ Vison工具包下的NI私有函数模块,优化了检测结果等相关环节。检测程序能对人力、物力、财力进行有效分配,配合工件二维码可实时自动记录检测结果,减少人员记录时间,提高工作效率。采用模式匹配建立灰度图像坐标系原点方法,可作为故障诊断、尺寸测量前图像精确定位的最常用策略方法之一。In order to realize the error prevention of bolt cotter pin based on machine Vision,the architecture of error diagnosis program is designed.With the help of Vision Assistant,function blocks of image acquisition,image gray processing and error diagnosis script are built.The configuration of pattern matching and coordinate system and the routine detection process of error diagnosis are introduced.In the LabVIEW programming environment,NI Vision Builder and NI private function module under IMAQ Vison toolkit are used to optimize the detection results and other related links.The detection program can effectively allocate manpower,material resources and financial resources,and automatically record the detection results in real time with the workpiece two-dimensional code,reducing the recording time of personnel and improving work efficiency.The method of establishing the origin of gray-scale image coordinate system using pattern matching can be used as one of the most common strategies for fault diagnosis and accurate image positioning before dimensional measurement.
