Social security card identification method and system

Abstract

The embodiment of the invention provides a social security card identification method and system, and belongs to the technical field of identification and verification. The social security card identification method comprises the following steps: acquiring an image to-be-identified area of a card and a corresponding pixel size; determining the actual size of the card based on the distance between the device for capturing the image of the card and the card and the pixel size; when the actual size is the same as the target size of the social security card, obtaining feature information of the card in a preset area, and the preset area is configured to be an area capable of showing the type of the social security card; inputting the feature information into a preset character recognition model to obtain character information output by the character recognition model; obtaining target printing data of the card from a social security card manufacturing system; and when the character information output by the character recognition model is matched with the target printing data, determining that the card is qualified. According to the method, whether the production of the social security card is qualified can be detected, the graphic characters of the social security card under different backgrounds can be identified, and the identification result is more accurate.

Description

technical field [0001] The invention relates to the technical field of identification and verification, in particular to an identification method and system for a social security card. Background technique [0002] With the development of intelligent manufacturing, the manufacturing industry is developing in the direction of unmanned workshops. For the production or inspection institutions of social security cards, unmanned has not been fully realized in the process of production or verification. After issuing a social security card, how to check whether the copied information on the top is correct, whether the size is qualified, and whether the content meets the character requirements. The entire proofreading process still requires manual detection and management. At this stage, the technology of Chinese character recognition is also disclosed. However, when the background pattern on the social security card changes (the background of the social security card in different r...

[0002] With the development of intelligent manufacturing, the manufacturing industry is developing in the direction of unmanned workshops. For the production or inspection institutions of social security cards, unmanned has not been fully realized in the process of production or verification. After issuing a social security card, how to check whether the copied information on the top is correct, whether the size is qualified, and whether the content meets the character requirements. The entire proofreading process still requires manual detection and management. At this stage, the technology of Chinese character recognition is also disclosed. However, when the background pattern on the social security card changes (the background of the social security card in different regions is different), it will become extremely difficult to recognize the graphic text on the social security card
