| titleOfInvention | A method for detecting the bad state of the hexagonal nut falling off of the double-sleeve connector of the high-speed rail catenary based on the cascade classifier |
| abstract | The invention discloses a method for detecting the bad state of a hexagonal large nut of a double-sleeve connector part of a high-speed rail catenary based on a cascade classifier. It includes the following steps: first, establish a sample library about the double-sleeve connector parts, extract the HOG features of the samples to train the cascaded AdaBoost classifier, and train the support vector machine classifier on this basis to realize the location of the double-sleeve connector parts. Second, the Hough transform is used to extract the inclination angles of the flat and oblique wrists connected by the double casing in the target image, and the flat wrists are rotated to the horizontal direction, so as to realize the segmentation of the flat and the connectors; The wrist arm is rotated to the vertical direction to realize the separation of the inclined wrist arm and the connector. During fault determination, in the extracted connector image, the horizontal baseline is set according to the position of the light spot, and its horizontal grayscale singular value is detected to make accurate judgment on the failure of the double-sleeve connector hexagonal large nut falling off. |
