Abstract

The invention relates to an arc-shaped finger vein recognition device. The arc-shaped finger vein recognition device includes a shell; a bottom cavity is formed in the bottom of the shell; a side cavity is formed in one side of the shell; an arc-shaped finger placing groove is formed in the shell; an optical filter located at the top of the bottom cavity is arranged below the arc-shaped finger placement groove; an infrared camera is arranged on one side of the interior of the bottom cavity, an inclined reflector is arranged on one side of a lens of the infrared camera and located below the optical filter, a vertical main board is arranged in the side cavity, an infrared lamp groove is formed in the top of the side cavity, and an infrared lamp located on one side above the arc-shaped fingercontaining groove is arranged in the infrared lamp groove. According to the invention, the user experience is improved, and the vein blood vessel image acquired by the finger vein recognition devicedoes not become shallow or disappear.

Description

technical field [0001] The invention relates to the technical field of finger vein recognition, in particular to an arc-shaped finger vein recognition device. Background technique [0002] The finger positioning groove (finger placement groove) of the traditional finger vein recognition device is set in a straight line. As a practitioner, I have deeply experienced that the finger joints will be very painful after using it too much. Because you need to straighten your fingers every time you use it, it will cause fatigue to the knuckles, and because of the straight state, the blood vessels in the fingers will also be squeezed to a certain extent. The slower blood flow will make the vein image acquired by the finger vein recognition device lighter or partly disappear. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technologies and provide an arc-shaped finger vein recognition de...
