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 present application discloses a fingerprint entry method and related devices, which are applied to electronic equipment. The electronic equipment includes a display screen and an off-screen fingerprint module set relative to a preset area of ​​the display screen. The method includes: displaying on the display screen The fingerprint entry setting interface, the fingerprint entry setting interface includes the add fingerprint function button; when the selection operation for the add fingerprint function button is detected, at least one screen image of the user's finger not pressing the fingerprint recognition area is collected through the under-screen fingerprint module , the fingerprint identification area includes a preset area; the fingerprint entry guide interface is displayed on the display screen, and multiple fingerprint images when the user's finger presses the preset area are collected through the fingerprint module under the screen; according to at least one screen image and multiple fingerprint images Fingerprint image, generate fingerprint template to complete the fingerprint entry process. The embodiments of the present application are beneficial to improving the accuracy of fingerprint entry of electronic devices and reducing the rejection rate FRR of fingerprint recognition.

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...
