基于迟滞阈值分割的瓶口缺陷检测方法

随着工业机器人和现代化工业的快速发展,人们对工业机器人的性能要求越来越高,为了提高工业生产的效率和产品的质量,智能、高速、高精度是工业机器人的必备要求。国内基于机器视觉的智能啤酒瓶口缺陷检测方法中,高速、高精度仍是一个亟待解决的问题。为此,提出了一种基于随机圆拟合评估的四圆周定位法,大大提高了瓶口检测区域的定位精度,并提出了基于投影特征的分区域磁滞阈值分割的智能瓶口缺陷检测方法。对采集的488幅灰度图像进行测试,检测正确率为99.4%,检测平均速度为38 ms,算法的检测速度快,检测精度高,可以很好地应用到高速、高精度的现代化工业机器人中。

Bottle mouth defect detection method based on hysteresis thresholding segmentation

With the development of industrial robots and modern industrial,the more performance requirements for industrial robots are needed.To improve production efficiency and product quality,intelligent,high speed and high precision are essential requirements for industrial robots.In summary of domestic intelligent beer bottle mouth defect detection method based on machine vision,high-speed and high-accuracy is still a problem to be solved.This paper presents the four-circle positioning method based on circle fitting assessment method,which greatly improves the accuracy of bottle mouth detection area,and the smart bottle mouth defects detection method based on sub-region hysteresis thresholding segmentation of projection features.Collected 488 image tests,the detection accuracy is 99.4％,the average speed of detection is 38 ms.The algorithm proposed in this paper has high detection speed and high detection precision,it can be well applied in the modern industrial robot with high speed and high precision.
