Abstract

The invention discloses a label detection method, device and equipment and a computer readable storage medium, and the method comprises the steps: carrying out the preprocessing of a to-be-detected image, and obtaining a vertical histogram based on a pixel value; carrying out interception conversion processing on the binarized image according to the vertical histogram to obtain a target grayscale image; according to the matching template of the target label, carrying out standard square deviation matching processing on the target grayscale image to obtain an actual position of the target label in the to-be-detected image; and according to the actual position of the target label in the to-be-detected image, judging whether the target label is correctly pasted or not. Compared with the prior art that the gray histogram of the label is used as the retrieval template and is matched with the to-be-detected solar cell panel, the detection result accuracy is higher, the detection accuracy of the label position is improved, and the pasting effect of the target label is ensured.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a label detection method, device, equipment and computer-readable storage medium. Background technique [0002] In order to distinguish each solar panel, a label that can uniquely identify the solar panel is attached to the fixed position of the solar panel. During the production process of the solar panel, it is necessary to check the correctness of the label on the solar panel. [0003] At present, the inspection of labels on solar panels generally uses the grayscale histogram of the label as a retrieval template to match with the solar panel to be inspected, but the accuracy of this inspection method is not high, and in most cases only the label can be identified Whether the appearance is defective, it is impossible to accurately identify the effect of label application. Contents of the invention [0004] This application provides a label detection m...
