Abstract:
A fingerprint identification method, includes: collecting a first fingerprint image according to a sampling parameter; determining a collection environment of the first fingerprint image according to the first fingerprint image and a pre-stored reference image, wherein the reference image is a fingerprint image obtained under a reference light environment; processing the first fingerprint image according to a processing parameter corresponding to the collection environment; and performing fingerprint identification according to the processed first fingerprint image. By pre-storing the reference image, the present application can quickly judge the collection environment of the fingerprint by collecting only one fingerprint image, which saves time for collecting the fingerprint image and judging the collection environment, and improves the identification efficiency of the fingerprint effectively.
