Problems solved by technology

[0003] At present, the cost of palm vein collection devices is relatively high, and the performance is mainly restricted by the two major elements of the emission light source and the camera. The palm vein images collected in different environments will have problems such as shadows, bright spots, and image blur.
The collected palm vein images will seriously affect the accuracy of the entire palm vein recognition system.

Abstract

The embodiment of the invention provides a palmar vein acquisition apparatus and a palmar vein identification system. The palmar vein acquisition apparatus illuminates a palmar vein acquisition area through a lighting module, a near infrared camera module completes palmar vein image acquisition, and the palmar vein image is uploaded through an image transmission module. The apparatus can control the working state of the lighting module and the working state of the near infrared camera module through a control module, wherein the lighting module sleeves the near infrared camera module and comprises a plurality of near infrared LED lamps which are uniformly distributed on the periphery of the near infrared camera module to light up the image acquisition area. The near infrared camera module is placed in an inner box, which is embedded in an outer box. The cost is reduced, and real-time and stable acquisition of palmar vein images can be realized.

Description

technical field [0001] The invention relates to the technical field of biometric identification, in particular to a palm vein collection device and a palm vein recognition system. Background technique [0002] In the prior art, authentication systems based on passwords and knowledge (eg, based on mobile phone numbers, passwords, etc.) are easy to be stolen or cracked. Therefore, authentication systems based on biometric features are increasingly favored by people. Biometrics include fingerprints, veins, etc. Today, most devices are unlocked with a fingerprint. Compared with fingerprint identification technology, the security of vein biometric identification technology is better. The current vein biometric recognition technology is mainly divided into: finger vein recognition technology, hand vein recognition technology and palm vein recognition technology. Compared with finger veins, the palm vein network is more complex and has more texture feature information; compared...
