Title:
FINGER VEIN IMAGE ACQUISITION DEVICE AND INTELLIGENT LOCK
Document Type and Number:
WIPO Patent Application WO/2019/024320
Kind Code:
A1
Abstract:
A finger vein image acquisition device and an intelligent lock. The finger vein image acquisition device comprises a light source module (101), an image acquisition module (102), and a finger in-place monitoring module (105). The light source module (101) and the image acquisition module (102) are provided opposite to each other. A finger accommodating space (103) is formed between the light source module (101) and the image acquisition module (102). The finger in-place monitoring module (105) is provided on the surface in the finger accommodating space (103) that is in contact with the fingertip of a finger. The position of the finger located in the finger accommodating space (103) is monitored by means of the finger in-place monitoring module (105). The light source module (101) is triggered to emit infrared light radiated to the finger accommodating space (103) only when the finger reaches a preset position, and meanwhile, the image acquisition module (102) is woken up to acquire a vein image of the finger located in the finger accommodating space (103). Thus, the position and angle of the finger can be relatively fixed each time a finger vein image is acquired, so that the image acquisition module (102) may acquire a stable and reliable vein image, thereby improving the recognition rate of the vein image.
