The invention discloses an OCR Recognition effect evaluation method and device. The OCR recognition effect evaluation method provided by the invention comprises the following steps: performing optical character recognition on a specific evaluation sample image through a to-be-evaluated OCR recognition model to obtain model recognition result data output by the to-be-evaluated OCR recognition model; comparing the model identification result data with standard identification result data; and when the model recognition result data is closer to the standard recognition result data, taking that the recognition effect of the OCR recognition model is better. Therefore, the recognition effect evaluation result of the OCR recognition model is obtained, and the influence of subjective factors on the evaluation result is avoided. And the technical problems of inaccurate evaluation result and long evaluation period of an existing OCR Recognition algorithm evaluation mode are solved without a stage of use experience.
Description
technical field [0001] The present application relates to the field of technical optical character recognition, in particular to a method and device for evaluating OCR recognition effects. Background technique [0002] OCR technology (Optical Character Recognition, Optical Character Recognition) is currently widely used in related fields such as handwriting recognition, print recognition, and text image recognition. It can be as small as document recognition, license plate recognition, bank card recognition, ID card recognition, bill recognition, invoice recognition, etc., as large as advertisement and poster content recognition. The invention of OCR technology has greatly simplified the way we process data. [0003] OCR can be divided into two categories: handwriting recognition and printed recognition. According to the current OCR recognition ability, the recognition accuracy of printed characters is much higher than that of handwritten characters. Although the OCR reco...
