Electrode plate alignment degree detection method, device and equipment based on battery CT image and medium

Abstract

The invention discloses an electrode slice alignment degree detection method, device and equipment based on a battery CT image, and a medium. The method comprises the following steps: acquiring a region of interest in a battery CT image of a layer where a to-be-detected electrode slice is located; extracting positive line points in the region of interest on the basis of the gray value, and determining a positive line sequence according to the extracted positive line points; for each positive line, upwards searching an uppermost positive pole point and downwards searching a lowermost negative pole point according to the gray value; and calculating a left-right range according to the positive pole and the negative pole of each positive line so as to determine the alignment degree of the to-be-detected electrode plate. According to the method, the region of interest is determined in the battery CT image of the layer where the to-be-detected electrode plate is located, the positive pole and the negative pole are determined in the region of interest based on the gray value, and the electrode plate alignment degree is calculated according to the positive pole and the negative pole, so that the characteristics of the positive line point can be fully utilized, the influence of image noise on electrode line selection is avoided, and the detection accuracy is improved. Therefore, the accuracy of the alignment degree of the electrode plates can be improved.
