M310 nuclear power unit equipment label position number image identification method

Abstract

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 left upper corner, the right upper corner, the left lower corner and the right lower corner. The method can reduce the human factor fault probability of the nuclear power fieldworkers, and reduces the operation cost of the nuclear power plant.

Description

technical field [0001] The invention belongs to the technical field of image recognition, and in particular relates to an image recognition method for an M310 nuclear power unit equipment tag number image. Background technique [0002] Every piece of equipment in a nuclear power unit has a unique equipment tag corresponding to it. The complete M310 nuclear power unit equipment tag includes 1 unit identification number + 3 system identification numbers + 3 equipment serial numbers + 2 equipment type numbers. For example, 1CRF001PO represents the No. 1 pump of the circulating water system of Unit 1. The maintenance, operation, and management activities of the nuclear power site are all carried out around the equipment tag. Effective identification of equipment tag numbers can improve the efficiency of nuclear power production activities, and improving the accuracy of equipment tag identification can effectively prevent personnel errors from causing unpredictable personnel in...
