摘要
Abstract
A detection method suitable for circular component center point is designed to achieve the positioning of valve guides,blind cover holes,protective sleeve holes and other components through Machine Vision.Firstly,it uses threshold segmentation,dilation,corrosion and other algorithms to preprocess the image and filter out the region where circular components are located.Secondly,it finds the center of the area where the circular component is located,uses this center as the measurement center for the circular caliper tool,sets the detection radius and dynamic measurement range of the caliper,so that the measurement range covers the outer contour of the circular component.It uses the caliper measurement operator to find the intersection point set between the circular contour and the caliper grid.Finally,the center point of the circle is obtained using the method of least squares arc approximation to locate the circular component.Research has shown that this method has strong robustness,high accuracy,and improves the accuracy of assembly.关键词
