Contact network detection method

The invention provides a contact network detection method, which belongs to the technical field of electrified railway equipment state performance detection, and comprises the following steps: obtaining contact network detection data; performing color correction on the contact network detection image; performing contrast enhancement on the color correction image; performing weighting processing on pixel features and channel features by using a convolutional neural network for constructing space attention and channel attention calculation branches; extracting an effective edge of the image by using a Canny operator; carrying out image annotation, and making a sample data set; and carrying out detection model training by using the positive sample data set and the negative sample data set, and carrying out detection to obtain a detection result. According to the method, the detection image data obtained in a severe environment can be enhanced in a targeted manner, the use efficiency of the detection data is impr
