Problems solved by technology

[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

Embodiment 1

[0053] figure 1 It is a flowchart of an identification method of a social security card of the present invention, such as figure 1 As shown, the identification method of the social security card includes:

[0054] S101, acquire the image to-be-recognized area of ​​the card and its corresponding pixel size; wherein the image to-be-identified area is the actual area of ​​the entire card, similar to taking a photo, using this method to identify the area where the card is located, The image clipping method of the present invention is static clipping, that is, the image is clipped after the image has been shot to obtain useful parts of the image. In the actual detection process, the social security card is generally placed on a desktop with a large contrast for image The shooting of the image facilitates the subsequent processing of the image. After determining the area to be identified in the image (that is, the image where the card is located), the pixel size of the image identi...

Embodiment 2

[0073] Figure 4 The present invention also provides a module block diagram of an identification system of a social security card, such as Figure 4 As shown, the identification system of the social security card includes: a size acquisition unit, which is used to acquire the image to be identified area of ​​the card and its corresponding pixel size; The distance of the card and the pixel size determine the actual size of the card; the feature acquisition unit is used to acquire the feature information of the card in a preset area when the actual size is the same as the target size of the social security card , wherein the preset area is configured as an area capable of showing the type of the social security card; an information input unit is configured to input the feature information into a preset character recognition model, and obtain the output of the character recognition model Text information; a data acquisition unit for obtaining the target printing data of the card...

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...
