Acquisition method and device of character recognition model, computer equipment and storage medium

Abstract

The invention relates to a character recognition model obtaining method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a to-be-processed picture group, a character position labeling group, a character table and character fonts; obtaining a plurality of groups of expected character strings according to the character table and the character fonts, and converting the plurality of groups of expected character strings into a plurality of character string pictures; according to the character position labeling group, fusing each to-be-processed picture in the to-be-processed picture group with a corresponding character string picture in the plurality of character string pictures to obtain a plurality of fused pictures, and based on the character position labeling group and the plurality of groups of expected character strings, obtaining a plurality of fused character position labels; and training based on the to-be-processed picture group, the plurality of fused pictures, the plurality of fused character position labels and a preset character recognition model to obtain a character recognition model. By adopting the method, the number of samples can be increased, and the character recognition accuracy of the obtained character recognition model is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a method, apparatus, computer equipment and storage medium for acquiring a character recognition model. Background technique [0002] With the development of character recognition requirements, the requirements for the efficiency and accuracy of character recognition are getting higher and higher. In the existing acquisition methods of character recognition models, the character recognition models are mostly obtained by training about 100 pictures with annotations. [0003] However, in industrial scenarios, the industrial characters that need to be recognized are mostly component information or serial numbers. For the acquisition of character recognition models, it is often difficult to collect pictures containing all the characters expected to be recognized, or only a small number of pictures can be collected for training. In addition, professionals are r...

Problems solved by technology

[0004] Based on this, it is necessary to provide a character recognition model that can improve the accuracy of character recognition in view of the problem that the accuracy of character recognition is not high when there are only a small number of sample pictures or incomplete characters in the existing methods for obtaining character recognition models.
