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.
