Description
Technical Field
The utility model relates to a palm vein recognition technical field especially relates to a but non-contact palm arteries and veins recognition device of outdoor use.
Background
In the field of biometric identification, currently applied technologies include fingerprint identification, face identification, palmar vein identification, voiceprint identification, auricle identification, iris identification, gait identification, and the like. At present, the face recognition technology is widely applied, but the face recognition technology cannot meet the practical requirements in special situations. Especially, in the case of public health crisis, people are required to wear protective articles such as masks and goggles when entering or exiting public places or specific places due to the need of epidemic prevention and control, and the face recognition is difficult to play a role. And the other widely used fingerprint identification mostly needs to be scanned by pressing and contacting with fingers to obtain fingerprint information, but the contact mode is not favorable for epidemic prevention and control.
Therefore, compared with the biometric identification technologies such as fingerprints and human faces, the palm vein identification technology has the advantages that: the palm vein identification technology can carry out identity authentication in a non-contact mode, people can shoot and obtain a palm vein image through the palm vein image camera as long as a palm is naturally stretched to be close to an identification area, contact is not needed, and the requirement of epidemic situation prevention and control is met; the veins of the palms of the human bodies are hidden under the epidermal tissues, belong to the internal characteristics of the living bodies, are not easy to steal, copy and interfere, and have extremely high safety, accuracy and reliability.
In order to stably acquire a high-quality palm vein image, a palm fixing bracket or a supporting bracket is often adopted in a conventional palm vein image acquisition or identification device. In the utility model patent with the publication number CN 204181622U: the palm vein recognition device support frame, the palm vein recognition device and the identity recognition device disclose a palm vein recognition device support frame, namely a locator in a C shape, wherein one end of the locator is a finger locating part, and the other end of the locator is a wrist locating part.
