Abstract
The application relates to the technical field of character recognition in the technical field of artificial intelligence, in particular to the technical field of optical character recognition, and provides a text recognition method, which comprises the following steps: obtaining a text image to be recognized, each character in the text image extending along a single direction; obtaining an image feature sequence according to the text image, wherein the image feature sequence comprises 1*n features, and n is a natural number; recognizing a text line orientation according to the image feature sequence; and recognizing each character in the text image according to the image feature sequence and the text line orientation. Image feature sequence image feature sequence. The technical scheme provided by the application can recognize the text in the text image with an arbitrary angle of the text line orientation through the image feature sequence, and can reduce the operation amount of recognition, thereby improving the efficiency of recognizing the text.
