Embodiment Construction

[0031] Those skilled in the art understand that in the existing fingerprint recognition scenarios, the recognition of collected fingerprints needs to occupy more computing resources, the recognition speed is slow, and the calculation amount of the computer is huge.

[0032] The inventors of the present application found through analysis that the reason for the above problems is that the existing fingerprint identification scheme needs to identify each collected fingerprint image, which requires a large amount of calculation.

[0033] With the development of fingerprint recognition technology, the concept of multi-fingerprint recognition has also emerged as the times require. The multi-fingerprint recognition refers to: collecting fingerprint images of multiple fingers of the user at the same time. When the fingerprint images of the multiple fingers are successfully recognized , to determine that the identification of the user is successful.

Abstract

The invention discloses a fingerprint identification method and device, a storage medium and a terminal. The method comprises the steps of collecting a to-be-identified fingerprint image of a to-be-identified fingerprint; extracting prior data from the to-be-identified fingerprint image, wherein the prior data comprises an outer contour of the to-be-identified fingerprint; comparing whether the priori data is consistent with standard data or not, wherein the standard data comprises an outer contour of a standard fingerprint; and when the comparison result is consistent, identifying the to-be-identified fingerprint at least based on the to-be-identified fingerprint image. Through the scheme provided by the invention, the fingerprint identification efficiency can be improved, the calculationamount is reduced, and computer resources are saved.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification method and device, a storage medium, and a terminal. Background technique [0002] With the rapid development of science and technology, the application of biometric technology is becoming more and more extensive. Among them, the development and application of fingerprint recognition is the most popular. [0003] The process of the existing fingerprint identification scheme mainly includes: collecting the user's fingerprint data; comparing with the pre-entered fingerprint data in the background database; identifying the user's fingerprint according to the comparison result. [0004] However, in the existing fingerprint recognition scenarios, the recognition of the collected fingerprints needs to occupy more computing resources, the recognition speed is slow, and the calculation amount of the computer is huge.
