Title:
FINGER VEIN IMAGE ACQUISITION DEVICE AND INTELLIGENT LOCK
Document Type and Number:
WIPO Patent Application WO/2019/024319
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 finger in-place monitoring module (105) is provided on the light source module (101) and used for monitoring the position of a finger (104) located in a finger accommodating space (103), triggering the light source module (101) to emit infrared light radiated to the finger accommodating space (103) when detecting that the finger (104) reaches a preset position, and waking up the image acquisition module (102) to acquire a vein image of the finger (104) under radiation of the light source module (101). According to the device, the position of the finger (104) is monitored by means of the finger in-place monitoring module (105), and the light source module (101) and the image acquisition module (102) are triggered to operate only when the finger (104) reaches the preset position; thus, the position and angle of the finger (104) 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.
