The invention discloses a finger
vein recognizing
system which belongs to the technical field of biometric identification. The invention further discloses equipment which comprises a finger
vein image collecting device, an
image processing device and an image recognizing and storing device. The image collecting device is connected with the
image processing device through a
USB interface, and the
image processing device is connected with the mage recognizing and storing device through the
USB interface. The finger
vein recognizing
system comprises two
modes: an
authentication mode and a recognition mode, wherein, the
authentication mode is used for verifying whether a person to be verified is a designated person or not, that is, a user first selects a corresponding user number when the
system verification is performed; after finger vein images of the person to be verified are collected, a comparison is made between the finger vein images and the template which is stored in a
database and corresponds to the user number, so that whether the user is valid or not can be determined; the recognition mode is used for verifying which registered person the person to be verified is, that is, a comparison is made between finger vein image characteristics of the user and the template of the user in the
database; and then a template number with the greatest similarity is found, so as to determine the identity of the person to be verified.
