Abstract

The invention provides a character recognition method and device. The method comprises the following steps: acquiring at least one frame of character image to be recognized in a video; cutting the to-be-recognized character image to obtain a to-be-recognized character area; correcting the character area to be recognized through a classification network and a space transformation network; performing feature extraction on the corrected character area to be recognized through a feature extraction network; and inputting the extracted features into a CTC network to obtain a recognition result of the to-be-recognized character. According to the invention, the character recognition rate and recognition accuracy can be greatly improved.

Description

technical field [0001] The present invention relates to the technical field of machine learning, in particular to a character recognition method, a character recognition device, a computer device, a non-transitory computer-readable storage medium and a computer program product. Background technique [0002] In intelligent experimental scenarios, it is necessary to automatically recognize the digital display on the electronic balance to determine whether the weight displayed on the electronic balance is within the specified range. [0003] Affected by factors such as the uncertain position of the electronic balance, the uncertain length of the number, and the indoor lighting environment and camera angle, the use of traditional identification methods will cause problems such as low recognition rate and low recognition accuracy. Contents of the invention [0004] To solve the above technical problems, the present invention provides a character recognition method and device, w...
