Title:
FINGER VEIN IMAGE ACQUISITION DEVICE AND INTELLIGENT LOCK
Document Type and Number:
WIPO Patent Application WO/2019/024321
Kind Code:
A1
Abstract:
A finger vein image acquisition device and an intelligent lock. The finger vein image acquisition device comprises a trigger generating module (101), a finger accommodating space (102), at least one light source module (103) and a plurality of image acquisition modules (104) which are separately connected to the trigger generating module (101). A center point of the projection of the finger accommodating space (102) on a vertical plane facing the user is determined. At least one light module (103) and the plurality of image acquisition modules (104) are evenly distributed around the center point on the projection on the vertical plane. Therefore, when finger vein image acquisition is to be performed, a finger to be acquired is placed in the finger accommodating space (102), so that the plurality of image acquisition modules (104) provided around the finger accommodating space (102) respectively acquire plane vein images of the finger at different angles. A three-dimensional vein image of the finger is generated by the trigger generating module (101) according to the plane vein images of the finger at different angles, so that the acquisition of the three-dimensional vein image of the finger is implemented. The recognition efficiency of finger vein images and the safety of the recognition are improved.
