OCR (Optical Character Recognition) intelligent recognition and management system for bacillus calmette guerin inoculation records

The invention relates to the technical field of image processing, in particular to a bacillus calmette guerin inoculation record OCR intelligent recognition and management system which comprises an image acquisition module, an image feature acquisition module, an enhanced image acquisition module and an image character recognition management module. The acquisition module is used for acquiring a gray-scale image of a to-be-identified BCG inoculation record; the extension degree and the writing logic factor of each character area pixel point in the gray level image; according to the extension degree of the target pixel point and the writing logic factor, obtaining an enhancement demand parameter of the target pixel point; correcting all character region pixel points in the gray level image according to the enhancement demand parameters, and obtaining an enhanced image of the to-be-identified bacillus calmette guerin inoculation record; and performing character recognition on the to-be-recognized bacillus calme
