Problems solved by technology

Since the user’s finger needs to press the fingerprint identification area during the fingerprint entry process under the screen, the cleanliness of the screen will affect the accuracy of fingerprint entry, which in turn will affect the False Rejection Rate (FRR) during the fingerprint identification process.

Embodiment Construction

[0024] Fingerprint identification technology corresponds a person with his fingerprints, and by comparing his fingerprints with pre-saved fingerprints and identifying them through the detailed feature points of different fingerprints, his true identity can be verified. Feature points refer to breakpoints, bifurcation points and turning points where fingerprint lines often appear interrupted, bifurcated or turned. Each person's fingerprint lines are unique in their patterns, breakpoints, bifurcation points and turning points. And its uniqueness is invariable throughout life. It is by virtue of this uniqueness and stability that we can create fingerprint recognition technology. Fingerprint recognition technology has the advantages of fast recognition speed, convenient collection and low price, and is widely used in image processing, pattern recognition, computer vision and many other disciplines. Such as figure 1 as shown, figure 1 A schematic diagram of collecting fingerprin...

Abstract

The embodiment of the invention discloses a fingerprint input method and a related device which are applied to electronic equipment, the electronic equipment comprises a display screen and an under-screen fingerprint module set relative to a preset area of the display screen, the method comprises the steps of displaying a fingerprint input setting interface in the display screen,wherein the fingerprint input setting interface comprises a fingerprint adding function button; when a selection operation for adding the fingerprint function button is detected, collecting at least one screen image under the condition that the finger of the user does not press the fingerprint recognition area through the under-screen fingerprint module, the fingerprint recognition area comprising a preset area; displaying a fingerprint input guide interface in a display screen, and collecting a plurality of fingerprint images under the condition that the finger of the user presses a preset area through a fingerprint module under the screen; And according to the at least one screen image and the plurality of fingerprint images, generating a fingerprint template to complete a fingerprint input process. According to the embodiment of the invention, the accuracy of fingerprint input of the electronic equipment is improved, and the false rejection rate FRR of fingerprint identification is reduced.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a fingerprint entry method and a related device. Background technique [0002] In the current off-screen fingerprint entry scheme of mobile phones and other electronic devices, the entry process is basically the same as that of traditional capacitive fingerprints, that is, the final fingerprint template entered into the system is formed by collecting fingerprint images when fingerprints are pressed several times. Since the user's finger needs to press the fingerprint identification area during the fingerprint entry process under the screen, the cleanliness of the screen will affect the accuracy of fingerprint entry, which in turn will affect the False Rejection Rate (FRR) during the fingerprint identification process. Contents of the invention [0003] Embodiments of the present application provide a fingerprint entry method and a related device, in order...
