Fingerprint registration method, device and electronic terminal

Abstract

An embodiment of the present application provides a fingerprint registration method and apparatus, and an electronic terminal. The fingerprint registration method includes: obtaining, according to a plurality of input fingerprint images, a plurality of registration evaluation data corresponding to multiple fingerprint images respectively, where the registration The evaluation data comprises at least one of the following: the image quality data of the fingerprint image and the fingerprint area data in the fingerprint image; calculating a variation range of a plurality of the registration evaluation data; and judging whether the variation range and a preset amplitude variation threshold. In the method, fingerprint registration is performed according to the determination result to determine whether the fingerprint image can be registered by calculating the relationship between the variation amplitude of the plurality of registration evaluation data and the preset amplitude variation threshold. The success rate of fingerprinting registrations for difficult-to-register populations increases the experience of such groups.

Description

technical field [0001] The embodiments of the present application relate to the technical field of fingerprint identification, and in particular to a fingerprint registration method, device and electronic terminal. Background technique [0002] With the development of fingerprint identification technology, more and more electronic terminals have applied devices and functions related to fingerprint identification to improve the security of electronic terminals through fingerprint identification technology. [0003] An important part of fingerprint recognition is fingerprint registration. In the prior art, when fingerprint registration is performed, a finger needs to be pressed onto the fingerprint recognition sensor of the electronic terminal to record fingerprint images, and fingerprint registration is performed according to the recorded fingerprint images. There are preset registration standards for fingerprint images inside the electronic terminal. If the entered fingerpri...

Problems solved by technology

[0004] However, there are still some people who have difficulties in fingerprint registration in real life, for example, because the fingerprint images entered have not met the registration standards because of dry fingers, shallow fingerprint lines, thin fingers, etc., people who cannot successfully register fingerprints

These people who have difficulty in fingerprint registration cannot use the fingerprint recognition function in electronic terminals, making the user experience poor
