Abstract

The invention discloses a method and a device for assisting with optical character recognition. The method comprises the following steps of: generating a format information string which is used for indicating the character type of a character string to be printed; saving the format information string; obtaining a character string image to be recognized corresponding to the character string to be printed, and obtaining the format information string; and segmenting the character string image to be recognized according to the format information string, and conducting optical character recognition to the segmented character string image to be recognized.

Description

technical field [0001] The present invention relates to the field of optical character recognition (Optical Character Recognition, OCR), in particular, to a method and device for assisting optical character recognition. Background technique [0002] The current optical character recognition system uses row segmentation and column segmentation to segment the character string image to be recognized into individual character unit image blocks one by one for recognition. It is necessary to find the feature data of the image block during segmentation and then process the segmentation, or rely on the character recognition feedback mechanism to improve the recognition rate. [0003] The current implementation method can refer to the following: [0004] For example, the patent application CN200810101591.6 discloses a method for segmenting radicals of Chinese characters by performing row and column segmentation on text images to obtain several character unit image blocks and identif...
