Abstract

The invention discloses vena digitalis dorsalis and finger dorsum line combined acquisition recognition device and method. The device comprises an outer shell, a multi-band light source, a broad bandpass filter, an image acquisition device and a main processing module, wherein a finger slot is formed in the top of the outer shell; the multi-band light source comprises a visible light and an infrared light, and is arranged on the outer shell above the finger slot, and light faces the finger slot; the board band pass filter, the image acquisition device and the main processing module are all arranged in the outer shell, the broad band pass filter is arranged right below the finger slot in a horizontal direction, the image acquisition device comprises a lens and an image sensor, only one setof image acquisition device is arranged, the lens is arranged on a light path behind the broad band pass filter, the image sensor is arranged on the light path behind the lens, and the multi-band light source and the image sensor are respectively electrically connected with the main processing module. The invention solves the problem in the prior art that one camera cannot acquire vena digitalisand finger dorsum line at the same time as one image for combined recognition, the device volume is reduced, and power consumption is reduced.

Description

Technical field [0001] The invention relates to the technical field of human body biometric identification, in particular to a device and method for joint collection and identification of dorsal finger veins and fingerprints. Background technique [0002] Biometric identification technology uses personal characteristics to identify or verify the identity of users. Finger vein and fingerprint recognition technology is a relatively advanced biometric identification technology. Finger vein recognition technology uses the vein distribution image in the finger for identification. The vein feature is a living feature that is difficult to forge and remains unchanged for a long time. The finger vein is located deep under the skin and has higher stability and anti-counterfeiting. [0003] To perform multi-modal identity authentication and recognition for finger prints and finger veins, the prior art requires two or more cameras to collect the finger print images and finger vein images respe...
