鼓风机转子工件尺寸和对称性的检测方法

针对工业生产中鼓风机转子工件的尺寸和对称性经常出现不符合标准的情况，本文利用转子工件图像，基于边缘检测技术设计一种转子尺寸和对称性的检测方法。为了减少原始图像的噪声点，本文方法基于高斯滤波对原始图像进行降噪和二值化处理，在此基础上，使用基于Canny算子的边缘检测算法和基于最小二乘法的圆拟合方法，对工件内部孔洞进行检测；同时，使用基于改进的Canny算法对工件外部边缘进行检测，获取较为连续的边缘像素点，设计比对方法和动态模拟实验对尺寸和对称性进行检验。实验表明本文提出的检测方法对转子工件的尺寸和对称性的检测效果良好。

Detecting Method for Workpiece Size and Symmetry of Blower Rotor

In view of the fact that the size and symmetry of the blower rotor workpiece often appear to be inconsistent with the standard in industrial production, this paper uses the rotor workpiece images to design a rotor size and symmetry detection method based on the edge detection technology. In order to reduce the noise point of original image, the method performs noise reduction processing and binarization processing on the original image based on Gaussian filtering. On this basis, the edge detection algorithm based on Canny operator and the round fitting method based on the least square method are used to detect the holes inside the workpiece. At the same time, the improved Canny algorithm is used to detect the outer edge of the workpiece to obtain relatively continuous edge pixel points, and the comparison method and dynamic simulation experiment are designed to test the size and symmetry. The experiments show that the detection method proposed in this paper has a good effect on the detection of the size and symmetry of the rotor workpiece.
