M310 nuclear power unit equipment label position number image identification method

The invention belongs to the technical field of image recognition, and particularly relates to an M310 nuclear power unit equipment label position number image recognition method. The method comprisesthe following steps of calling an open source computer vision library; collecting an image containing the BGR color mode of the equipment label on the M310 nuclear power site; storing the acquired image in a. Jpg or. png format; converting the BGR color mode into an HSV color mode; reading a maximum number of distribution conditions of all pixels of an HSV color mode picture in an HSV color spaceand yellow, green, red, blue and white tones, and judging the shading color of the sign; scanning the image in the HSV color mode in the S4 again to obtain a coordinate area where the color shading is located; carrying out pixel point interception and cutting on the obtained coordinate area to obtain an image of a BGR color mode of the equipment label; and analyzing the relative positions of thefour coordinates of the lef
