Method and device for Chinese character recognition

Abstract

The invention provides a device and a method for Chinese character recognition. The device comprises a first recognition unit, an error detection unit, an error correction unit and a second recognition unit, wherein the first recognition unit is used for dividing and recognizing document images to obtain recognition information, the error detection unit is used for obtaining position information of image units and recognition code information in the recognition information by the aid of the first recognition unit to detect mistakenly divided image units, the error correction unit is used for correcting the mistakenly divided image units detected by the error detection unit, and the second recognition unit is used for recognizing the image units corrected by the error correction unit to obtain corresponding recognition code information. By the aid of the recognition code information and the position information of the image units in the recognition information obtained after recognizing the document images, the mistakenly divided image units are detected and corrected, recognition accuracy can be improved, and the problems of the prior art are solved.

Description

technical field [0001] The invention relates to Chinese character recognition technology, in particular to a Chinese character recognition method and device. Background technique [0002] With the improvement of the correct rate of Optical Character Recognition (OCR: Optical Character Recognition), its application is becoming more and more extensive, for example, it is widely used in office automation. [0003] figure 1 It is a structural schematic diagram of an optical recognition engine in the prior art; figure 2 It is a schematic diagram of the image unit after the text image is segmented by the segmentation module 101 of the optical recognition engine; image 3 is a schematic diagram of selecting the segmented image unit; Figure 4 It is a schematic diagram of standard Chinese characters with a left-right structure. [0004] Such as figure 1 As shown, the optical recognition engine mainly includes: a segmentation module 101 and a recognition module 102; wherein, th...

Problems solved by technology

But in the process of realizing the present invention, the inventor finds that the defect of the above-mentioned technology is: as Figure 4 As shown, for a standard Chinese character with a left-right structure, such as "outside", and the left part and right part of the standard Chinese character with a left-right structure are both standard Chinese characters, namely "Xi" and "Bu", the optical recognition engine (OCR) will The Chinese characters with the left and right structure are segmented into two image units, even if the above-mentioned segmentation error correction method is used, the above-mentioned segmentation error problem cannot be solved, which eventually leads to recognition errors
