Page turning anomaly detection method

Abstract

The invention discloses a page turning abnormality detection method, comprising: setting and selecting a page number area type; intercepting a page number area image; optical character recognition; extracting candidate page numbers; filtering candidate page numbers; generating preliminary recognition results; smoothing and confirming processing; judging And mark the page turning exception type. The page turning anomaly detection method of the present invention can deal with complex situations such as the position change of the page number in the document, the confusion between the page number and the text number, and the failure or error of the optical character recognition algorithm, and automatically find and mark the abnormal situation in the document scanning, It provides convenience for subsequent manual verification and supplementary scanning, effectively improves the performance of automatic page-turning scanners, and ensures the quality and integrity of scanning results while reducing manpower and improving efficiency.

Description

technical field [0001] The invention relates to the technical field of page turning scanning, in particular to a method for detecting abnormal page turning. Background technique [0002] It is a significant and arduous project to digitize a large number of books and documents. In order to save manpower and improve efficiency, the automatic page-turning scanner has been developed and applied. The automatic page-turning scanner is an automatic device that can automatically flip through well-bound book documents and take them into electronic pictures page by page; automatic page-turning scanning Through the automatic page turning and shooting device, the instrument can efficiently complete the electronicization of paper documents without or with minimal manual intervention. [0003] In the prior art, automatic page-turning scanners often have abnormal situations such as missing pages and repeated pages during the working process, resulting in incomplete scanning results and in...

Problems solved by technology

However, the inventor found through research that this solution not only increases the hardware cost, but also the parameters of the detection device are not easy to set due to the different paper conditions, so it is still difficult to completely avoid abnormal situations such as missing pages or repeated pages, and cannot guarantee the integrity of the scanning results However, manual verification is still required page by page
