Abstract

The invention is suitable for the technical field of graphic processing, and provides an identification card edge detection method and device, and a storage medium. The method comprises the steps of obtaining a to-be-processed target frame in a target video; according to the position of the target frame, obtaining first key point information of an adjacent frame adjacent to the target frame, and the first key point information comprising corner point information of the identification card; inputting the first key point information and the target frame into a preset key point position trackingmodel to obtain second key point information of the target frame and judgment information of the target frame, the judgment information being used for representing whether the target frame contains anidentification card or not; and determining a first identification card detection result of the target frame according to the second key point information and the judgment information. The identification card edge detection method provided by the embodiment of the invention is less influenced by the complex background and / or fuzzy edge of the to-be-detected video frame, and the detection error issmall. The invention also relates to the field of digital medical treatment, and is used for quickly identifying patient identity documents.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a card edge detection method, device and storage medium. Background technique [0002] With the extensive use of various cards such as ID cards, social security cards and bank cards, related card identification services also follow. Among them, the edge (frame) detection of various cards is a very important part of card identification. [0003] The current card edge detection mainly uses neural network or traditional edge detection algorithm to find all the edge information in the image, and then sets various conditions to filter out some edge information to obtain the edge information of the card. [0004] The above method is prone to misjudgment in the case of complex background or blurred edges, resulting in edge detection errors and affecting the subsequent operation of other services such as card information extraction. On the other hand, the ...
