Equipment nameplate information identification method, system and equipment

The invention relates to an equipment nameplate information identification method, system and equipment, nameplate positioning, cutting and correcting are carried out on images obtained under different shooting angles and backgrounds according to nameplate corner positioning processing and image correcting processing, the influence caused by shot image inclination, background information and the like can be reduced, and the equipment nameplate information identification efficiency is improved. The difficulty of nameplate text detection and recognition is effectively reduced, and the robustness of nameplate text detection is improved. And through text detection and text recognition, high-precision text information extraction and recognition are realized. According to the method, automatic identification of the equipment nameplate information is realized, the adaptability to equipment nameplate text detection is relatively high, and the detection precision is relatively high. The method is especially suitable f
