Abstract

The invention relates to the field of finger vein image acquisition, and discloses a miniature portable finger vein real-time image acquisition and recognition device, which includes a housing and a finger vein image acquisition authentication component for acquiring finger vein images and performing finger vein image recognition; The finger sensing component is used to detect the presence of a finger and output a control signal to the finger vein image acquisition authentication component; the prompt component is used to receive the control signal and output a prompt signal. The invention has the effect of improving the accuracy of image acquisition.

Description

technical field [0001] The invention relates to the technical field of finger vein image acquisition and recognition, in particular to a miniature portable finger vein real-time image acquisition and recognition device. Background technique [0002] At present, finger vein recognition is an advanced biological internal feature living body recognition technology. This technology irradiates the finger with near-infrared light, takes an image of the finger vein, and then uses a specific algorithm to extract feature data from the image. The extracted feature data is stored during registration, and the extracted feature data is compared with the stored feature data during identification. Compare, give the result of identification and comparison, so as to achieve the function of precise identification. [0003] When the existing finger vein image acquisition device collects the finger vein, the person to be collected places his finger on the finger vein image acquisition device, ...
