Problems solved by technology
[0002] In related technologies, the text in the image can be recognized by methods such as neural networks. However, this method can only output one or several characters at a time according to the order of the text, and cannot output all characters at the same time. The recognition speed is slow and the operating efficiency is low. Low, and this method usually relies on the previous one or more characters as the recognition basis of the current character, therefore, this method has a long-term dependence problem, that is, the recognition of the current character is based on the character recognized many times before, causing the current character The recognition result is not accurate

Embodiment Construction
[0081] Various exemplary embodiments, features, and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numbers in the figures indicate functionally identical or similar elements. While various aspects of the embodiments are shown in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
[0082] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as superior or better than other embodiments.
[0083] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the term "at least one" herein mean...

The present disclosure relates to a character recognition method and device, electronic equipment, and a storage medium. The method includes: performing feature extraction processing on an image to be detected to obtain a semantic vector; predicting the number of characters in a character sequence in the image to be detected according to the semantic vector; Determine the position vector according to the number of characters; identify the character sequence according to the position vector and semantic vector. According to the character recognition method of the embodiment of the present disclosure, the position vector of the character sequence in the image to be detected can be obtained, and the character sequence can be recognized according to the position vector and the semantic vector, and all the characters can be recognized at one time based on the position vector, and processed The efficiency is high, and the method of recognizing all characters at one time does not rely on past recognition results, avoiding the problem of uncontrollable long-term dependence.
