Abstract

The invention discloses a finger vein recognition device based on three-dimensional image acquisition. The finger vein recognition device comprises an LED lamp. A detection area is arranged at the lower end of the LED lamp, and a camera device is arranged below the detection area; the image sensor is connected with the three-dimensional display device and the processor through the control unit, and the processor is connected with the storage device. The essence of the three-dimensional image recognition method of the device is to collect and transmit three-dimensional dot matrix information instead of picture information, so that the accuracy of image recognition is higher; the three-dimensional entity scene display effect of the veins is achieved through the brightness and hue changes of the dot matrix, and the changes and details of the veins can be more effectively observed; therefore, the real three-dimensional entity activity graph of the scene can be observed at any visual angle, and the display effect is better.

Description

technical field [0001] The invention relates to a finger vein recognition device based on three-dimensional image acquisition. Background technique [0002] With the advent of the information age, the security and confidentiality of information has aroused people's general attention. At present, compared with iris, face and other recognition technologies, fingerprint recognition technology is a relatively mature identity authentication technology in biometrics recognition technology, but it has some unavoidable shortcomings, such as fingers are too wet, too dry or appear Damage such as peeling of the finger, or dirt on the finger will affect the recognition effect. Finger vein recognition technology is a kind of biometric identification technology, which uses the vein distribution image in the finger for identity recognition. This technology can completely overcome many of the above shortcomings and make identity authentication more convenient and quick. Therefore, it is v...
