Method and device for realizing character recognition, computer storage medium and terminal

The invention discloses a method and device for realizing character recognition, a computer storage medium and a terminal, and the method comprises the steps: obtaining a character image containing a preset number of characters based on a PDF document, and carrying out the multi-character recognition of the character image; and under the condition that the multi-character recognition result contains the preset number of characters, determining a final recognition result of the characters contained in the PDF document according to the multi-character recognition result. According to the embodiment of the invention, the characters in the PDF file are read and rendered, which character specifically corresponds to the character image in the PDF file can be determined, under the condition that the multi-character recognition result contains the preset number of characters, quick confirmation of missing detection or multi-detection is realized, and the character recognition accuracy is improved according to the mul
