Title: FINGER VEIN ACQUISITION METHOD AND DEVICE
Abstract:
The present application provides a finger vein acquisition method and device. The acquisition method comprises: a finger sensing unit receives a first trigger instruction and sends a generated sensing signal to a control unit; after receiving the sensing signal, the control unit controls a first light source and a second light source in multi-angle light sources to be separately turned on or off; an image acquisition unit obtains at least two finger vein images when different light sources are turned on or off; an image fusion unit splices and fuses the finger vein images acquired by the image acquisition unit; and an image storage unit stores the spliced finger vein image obtained after fusion. Hence, by acquiring finger vein images from different angles and performing feature matching, fusion, and splicing, the finger vein acquisition method and device provided by the present invention can effectively solve the problem of rotation of a finger during a vein acquisition process.
