Palm vein image acquisition device

Technical field

The utility model relates to an identity acquisition device, in particular to a palm vein image acquisition device for recognizing user palm information.

Background technique

With the development of society, more and more occasions require identification, and the types of authentication technologies are increasingly diversified. At present, the main identification methods include RF card authentication and fingerprint authentication, which are widely used in information centers, financial departments, star-rated hotels, and intelligent communities. Moreover, with the rapid spread of mobile payment in recent years, in order to ensure the security and privacy of users in mobile payment, the use of identity recognition is the most effective solution.

The palm vein image recognition technology, as a newer identification technology, is based on the existing palm vein image acquisition device mainly by acquiring the vein image of the user's palm and sending the relevant image to the background server. The server matches the image with the pre-stored image to implement the user's identification. However, since the existing palm vein image acquisition device often fails to image due to the user's palm shaking during imaging, the device often needs to perform multiple imaging to successfully identify the user's identity, thus extending The time used for identification has greatly affected the user's experience. How to accurately image the user's palm and shorten the time it takes to identify is the current problem to be solved.

Utility model content

The object of the present invention is to provide a palm vein image acquisition device capable of avoiding imaging failure caused by palm shaking when acquiring a vein image of a user's palm, thereby shortening the time taken for identity recognition and improving the user experience.

In order to achieve the above object, the present invention provides a palm vein image acquisition device, comprising a base, a hand vein identifier disposed on the base for acquiring an image of a palm vein of a user, and the a power data line connected to the MPG;
