The invention discloses a method for recognizing the state of a square pressure plate of a power distribution cabinet based on hough transform image processing, including image acquisition, collecting an image of a square pressure plate of a power distribution cabinet, and backing up and saving it in a picture format; image correction, identifying four corners of a calibration line The pixel coordinates of the point in the image, and image correction based on this pixel coordinates; image cutting, the number of image arrays of the corrected square pressure plate of the power distribution cabinet obtained through the observation of the human eye; sign removal: in each cut In the image of the small switch area, the identification plate of the independent area where each small switch is located is cut off; the color extraction is performed on the independent area where the small switch is located according to the threshold value of the image color, and the target recognition is used for the foreground part of the small switch. The canny function performs edge line detection, and the detection and recognition results are output in matrix form.
Description
technical field [0001] The invention belongs to the technical field of electrical equipment image recognition, in particular to a method for recognizing the state of a square pressure plate of a power distribution cabinet based on hough transform image processing. Background technique [0002] With the development of the power system, in the field of power equipment fault detection, there are more square platen subsystems in the electrical control cabinet, which play an important role in the safety of power operation. Due to the large number of pressing plates in one inspection process and the wide distribution area, the current method is mainly manual inspection, which is accurate but inefficient, which is not conducive to rapid troubleshooting and causes waste of human resources. Contents of the invention [0003] The purpose of the present invention is to provide a method for recognizing the state of a square pressure plate of a power distribution cabinet based on hough...
