D11, image segmentation is carried out to the 2D fingerprint image, obtains target fingerprint area image；

The characteristic point distribution of D12, the analysis target fingerprint area image；

D13, circular image interception is carried out to the target fingerprint area image according to a not concentric of M, obtains M circle Finger-print region image, the M are the integer greater than 3；

D14, target circle finger-print region image is selected from described M round finger-print region image, the target is round The quantity for the characteristic point that finger-print region image is included is greater than other round fingerprint regions in described M round finger-print region image Area image；

D15, the target circle finger-print region image is divided to obtain N number of annulus, the ring width of N number of annulus is identical；

D16, since N number of annulus the smallest annulus of radius, by N number of annulus successively with preset fingerprint template Carry out Feature Points Matching, and the accumulative matching value for having matched annulus；

D17, stop carrying out Feature Points Matching immediately when accumulative matching value is greater than preset matching threshold value, and export 2D and refer to The successful prompting message of print image fingerprint recognition.

Wherein, electronic equipment can carry out image segmentation to 2D fingerprint image, obtain target fingerprint area image, in turn, The characteristic point distribution for analyzing the target fingerprint area image justifies the target fingerprint area image according to a not concentric of M Shape image interception obtains M round finger-print region image, and M is the integer greater than 3, selects from M round finger-print region image Target circle finger-print region image, the quantity for the characteristic point that target circle finger-print region image is included are greater than M round fingerprint Other round finger-print region images in area image, divide target circle finger-print region image to obtain N number of annulus, N number of circle The ring width of ring is identical, since N number of annulus the smallest annulus of radius, N number of annulus is successively carried out with preset fingerprint template special Sign point matching, and the accumulative matching value for having matched annulus can by different location or not in this way, in fingerprint identification process Characteristic point with fingerprint is equivalent to and samples to entire fingerprint image, and the sampling can cover entire fingerprint for matching Region, thus, corresponding property feature up to standard can be found from each region to be used to match, when accumulative matching value is greater than Stop carrying out Feature Points Matching immediately when preset matching threshold value, and export the successful prompting message of 2D fingerprint image fingerprint recognition, It so, it is possible quick and precisely identify fingerprint recognition.
