OCR SYSTEM EVALUATION METHOD, APPARATUS AND DEVICE, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/100452
Kind Code:
A1
Abstract:
Provided are an OCR system evaluation method, apparatus and device, and a readable storage medium. The method comprises: obtaining a training image, inputting the training image into an initial OCR system, so as to train the initial OCR system, and to obtain a corresponding OCR system after the training of the initial OCR system is completed (S10); inputting an image to be recognized into the OCR system to determine a character recognition result corresponding to the image on the basis of the OCR system (S20); and determining a character recall rate corresponding to the OCR system and a character recognition accuracy rate corresponding to the OCR system on the basis of the character recognition result and actual annotation data corresponding to the image, and calculating an evaluation index of the OCR system on the basis of the character recall rate and the character recognition accuracy rate so as to evaluate the performance of the OCR system on the basis of the evaluation index (S30). The problem in the prior art that character detection and character recognition are separately and independently evaluated, and consequently evaluation indexes cannot objectively reflect the overall performance of an OCR system is solved.
