Abstract

The invention relates to the technical field of artificial intelligence, and discloses a character recognition method and device based on a real plate, computer equipment and a storage medium, and themethod comprises the steps: starting a preset infrared light generator and a visible light generator; performing image acquisition processing on the real plate to obtain a first image; if the color value contrast of the second character pattern in the first image is greater than a preset contrast degree threshold, obtaining a second text; turning off the infrared light generator, and turning on apreset ultraviolet light generator; performing image acquisition processing on the real plate to obtain a second image; if the color value contrast of the first character pattern in the second imageis greater than a contrast degree threshold, obtaining a first text; and combining the first text and the second text to obtain a final character recognition result. Therefore, the accuracy of character recognition is improved. In addition, the invention also relates to a blockchain technology, and the character recognition model can be stored in the blockchain.

Description

technical field [0001] This application relates to the technical field of artificial intelligence, in particular to a method, device, computer equipment and storage medium for character recognition based on real boards. Background technique [0002] Text recognition is an important content in image and graphics processing in the field of artificial intelligence technology, mainly to recognize the text in the image as text. Existing text recognition schemes perform poorly in recognizing real boards with mixed text (such as house plates, license plates, etc.), for example, when performing text recognition on real boards with mixed Chinese characters and letters, the computational resources spent Many, the recognition accuracy is low, so the recognition accuracy of existing text recognition schemes for real plates needs to be improved. Contents of the invention [0003] The main purpose of this application is to provide a character recognition method, device, computer equipm...
