Text recognition method of electrical equipment nameplate based on improved similarity

In the text recognition on the electrical equipment nameplate, Chinese characters are very special. As pictographic characters, there are a lot of typographic characters in Chinese characters, which have a certain difficulty in recognition. Therefore, this paper proposed a CRNN and string text similarity calculation of electrical equipment nameplates identification method. In addition, the similarity algorithm is improved according to the characteristics of Chinese characters. Finally, the electrical equipment nameplates under different illumination are collected as experimental samples, and the electrical nameplate recognition system designed in this paper is used for recognition. The experimental results show that this method has strong practicability.
