Abstract

The invention relates to an automatic nameplate recognition method and device, computer equipment and a storage medium. The method comprises the steps: obtaining a to-be-identified nameplate image; performing perspective transformation processing on the nameplate image to obtain a corrected image; extracting a character region in the corrected image to obtain a text image; based on convolutional recurrent neural network processing, performing conversion processing on the text image to obtain character information. According to the method, the perspective correction is performed on the nameplate image in the preprocessing stage to obtain the corrected image, and the accuracy of subsequent text recognition is improved. The text image in the corrected image is extracted through the text extraction box, the subsequent recognition range is narrowed, and the retrieval efficiency is improved. The convolutional network and the recurrent neural network are used to effectively identify the intrinsic context information in the text, convergence in detection is faster, and the recall rate of text detection and the accuracy of word-level detection box segmentation are improved.

Description

technical field [0001] The present application relates to the technical field of nameplate recognition, in particular to a nameplate automatic recognition method, device, computer equipment and storage medium. Background technique [0002] The substation system is very complex, and there are many types and quantities of substation equipment. Therefore, in inspection and maintenance, it is often necessary to identify the nameplate of the substation equipment to determine the model and manufacturer of the equipment, and then carry out targeted maintenance. At present, in most cases of power transformation enterprises, the nameplate of the equipment is identified manually. However, by manually identifying the nameplate, on the one hand, the labor cost will be increased. On the other hand, in the case of recognizing human fatigue, the accuracy of human recognition will drop significantly. [0003] Nowadays, with the promotion of intelligent detection and recognition, intellige...
