Abstract

The invention provides a method and a device for fingerprint identification. The fingerprint identification method comprises steps: a to-be-identified fingerprint image is acquired; the fingerprint image is divided into multiple regions, and according to a fingerprint matching algorithm corresponding to any region in the multiple regions, fingerprint features in the any region are matched with features in a corresponding region of a reference fingerprint image; and according to the matching rate of the fingerprint features in the any region, whether the to-be-identified fingerprint image is successfully matched with the reference fingerprint image is determined. According to the technical scheme of the invention, through carrying out different region dividing on the acquired fingerprint image, a different algorithm is adopted to process a different region, the fingerprint identification can be quickly carried out, the fingerprint information utilization rate during the fingerprint identification process can be improved, and the success rate and the accuracy for fingerprint identification can be further improved.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification method and a fingerprint identification device. Background technique [0002] At present, fingerprint identification technology, as a relatively mature biometric identification technology, has been widely used in many fields. However, fingerprint identification usually needs to collect fingerprint images first. During the collection process of fingerprint images, since the orientation of each printing is not exactly the same, different focus points will bring different degrees of deformation. Therefore, how to process the collected fingerprint images will be difficult. Affects the accuracy of the entire fingerprint recognition. [0003] In the related art, for the processing method of fingerprint image, it is usually to generate an image smaller than the original image (such as figure 1 102) to reduce the amount of relevant finger...
