摘要
对变形的螺母进行人工决策,判断能否继续使用时,会存在很大的主观性,为此提出基于机器视觉的卡尺工具法实时检测系统。该检测系统首先通过CCD相机对螺母图像进行采集,再用Halcon算法库对采集的图像进行分析处理,实验提出基于卡尺工具的边缘检测方法对螺母内径进行圆拟合,通过测量拟合圆的直径对螺母进行检测,最后通过C#做出界面实现检测功能。经实验验证,该检测系统正确率高、测量精度可控,测量时间不超过60 ms。
It is very subjective to make a manual decision on the deformed nut and judge whether it can continue to be used.Therefore,a real-time nut measuring system based on machine vision caliper tool method was proposed.Firstly,the nut image was collected by CCD camera,and then analyzed and processed with Halcon algorithm library in the system.The edge detection method based on caliper tool was proposed to fit the nut inner diameter circle,and the nut was detected by measuring the diameter of the fitting circle.Finally,C# was used to realize the detection function.Experimental results show that the system has high accuracy and controllable measurement accuracy,and the measurement time does not exceed 60 milliseconds.
