Abstract

The invention discloses a fingerprint registration method and system and electronic equipment. The fingerprint registration method comprises that a fingerprint sensor obtains a first image of first fingerprints, the first image is analyzed to obtain a standard feature library of the first fingerprints, the standard feature library comprises N standard feature points, and N represents a natural number; when fingerprints are verified, the fingerprint sensor obtains an image of the fingerprints to be verified, the image of the fingerprints to be verified is analyzed to obtain information of the fingerprints to be verified, the information of the fingerprints to be verified is compared with the standard feature library, and whether fingerprint verification succeeds is determined; and when fingerprint verification succeeds the image of the fingerprints to be verified is analyzed to obtain feature points different from the N standard feature points are obtained and serve as new standard feature points, and the new standard feature points are added to the standard feature library. According to the invention, the fingerprint can be registered and verified at the same time, and a function corresponding to fingerprint verification is implemented therefore.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, and more specifically, to a fingerprint registration method, a fingerprint registration system and electronic equipment. Background technique [0002] With the development of science and technology, various electronic devices are more and more widely used in people's work and daily life, bringing specific convenience to people's work and daily life, improving people's quality of life and Work efficiency has greatly accelerated the development of society.
