摘要:
针对在核电蒸发器传热管涡流检测过程中,需要提高管板爬行器找到待检测传热管管孔中心精度的问题,迁移采用机器视觉定位技术,提出一种基于霍夫梯度圆和最小二乘法的视觉定位方法来精确定位传热管管孔中心并拟合出管孔圆。首先对待测图像进行 Canny 边缘检测和霍夫梯度圆检测,然后依次遍历 Canny 边缘图中的每个边缘点,根据计算该边缘点到所有霍夫梯度圆圆心的距离来判断计算结果与该霍夫梯度圆半径之间的差距是否在误差范围之内进行投票,遍历完毕后取票数最多的霍夫梯度圆下的边缘点为有效边缘点集,最后通过最小二乘法拟合出圆中心及半径。通过和传统霍夫梯度圆检测方法的对比实验,结果表明所提方法的定位精度高、抗干扰能力强及泛化能力强,具有现场环境下高精度、高效率的定位检测功能。
Abstract:
In the process of eddy current testing in the heat transfer tubes of nuclear power evaporators , there is a need to improve the accuracy of the crawlers in locating the center of the heat transfer tube holes to be tested.This paper proposes a machine vision positioning method based on the Hough gradient circle and least squares fitting to accurately locate the center of the heat transfer tube hole and fit the hole circle.The method first performs Canny edge detection and Hough gradient circle detection on the test image , and then iterates through each edge point in the Canny edge map.Based on the distance between the edge point and the center of all Hough gradient circles , the method determines whether the calculated result is within the error range of the radius of the Hough gradient circle and casts a vote accordingly.After iterating through all the edge points , the effective edge point set is determined based on the Hough gradient circle with the highest number of votes , and the circle center and radius are finally fitted using the least squares method.Compared with the traditional Hough gradient circle detection method , the experimental results show that this method has high positioning accuracy , strong anti-interference ability , and strong generalization ability , and has the function of high-precision and efficient positioning detection in field environments.
