Abstract

The invention discloses an infrared LED finger vein collecting device with adjustable brightness, and belongs to the technical field of finger vein collection. The infrared LED finger vein collectingdevice comprises a box body, a finger fixator, a DSP controller, digital potentiometers and infrared light source arrays. Installation slots are arranged at the top of the box body. The infrared lightsource arrays are installed in the respective installation slot through lifting handles. The digital potentiometers are arranged on the lifting handles. Interface slots are arranged at the side of the box body. Laying grooves are arranged between the interface slots and the installation slots. Arc grooves are arranged between the laying grooves and the installation slots. Spiral adjustment knobsare arranged at the side of the box body. The invention solves the problem that the image of the finger vein collected by using a common light source in the prior art is unclear and cannot meet the requirement, can adjust the position of the finger relative to a CMOS camera and the infrared light source arrays, and is convenient for finger vein image collection.

Description

technical field [0001] The invention relates to a finger vein collection device, in particular to an infrared LED finger vein collection device with adjustable brightness, belonging to the technical field of finger vein collection. Background technique [0002] With the development and progress of society, information technology has gradually integrated into people's work and life. While bringing convenience to human society, it also puts forward higher and newer requirements for information security and confidentiality. However, at present Commonly used identity authentication methods, such as passwords, passwords, keys, ID cards, etc., have problems such as easy damage, forgetting, theft, and deciphering, which bring a lot of trouble to people's daily life, and even cause major property and life safety. Hidden dangers, therefore, human body biometrics has become a research hotspot in this century to meet the needs of the times, and it has also brought a huge economic marke...
