Embodiment 1

[0052] Such as image 3 As shown, the first embodiment of the present invention proposes a fingerprint simulation method, which includes the following steps:

[0053] S300, collecting fuzzy fingerprint images of the user multiple times.

[0054] Specifically, the fuzzy fingerprint image of the user is collected by the fingerprint collection module of the mobile terminal. After M times of collection, M fuzzy fingerprint images are obtained.

[0055] refer to Figure 5 As shown, it is a schematic diagram of collecting the fuzzy fingerprint image by the mobile terminal. The fingerprint collection module displays a fingerprint collection area on the touch screen of the mobile terminal. When the user touches the fingerprint collection area with a finger (such as the right thumb), the fingerprint collection module detects the fingerprint of the finger. information, generating the fuzzy fingerprint image according to the fingerprint information.

Embodiment 2

[0071] like Figure 4 As shown, the second embodiment of the present invention proposes a fingerprint simulation method. In the second embodiment, steps S400-S408 of the fingerprint simulation method are similar to steps S300-S308 of the first embodiment, except that the method further includes steps S410-S416.

[0072] The method includes the following steps:

[0073] S400, collecting fuzzy fingerprint images of the user multiple times.

[0074] Specifically, the fuzzy fingerprint image of the user is collected by the fingerprint collection module of the mobile terminal (see Figure 5 shown). After M times of collection, M fuzzy fingerprint images are obtained.

[0075] S402. Calculate a feature vector of each fuzzy fingerprint image.

[0076] Specifically, after M fuzzy fingerprint images are collected, each of the fuzzy fingerprint images is first divided into N small squares (see Figure 6 shown). For each fuzzy fingerprint image, the feature vector of the fuzzy fin...

Embodiment 3

[0106] like Figure 7 As shown, the third embodiment of the present invention proposes a mobile terminal 7 . The mobile terminal 7 includes a memory 70 , a processor 72 , a fingerprint collection module 74 and a fingerprint simulation system 76 .

[0107] In this embodiment, the fingerprint simulation system 76 includes:

[0108] The receiving module 700 is configured to receive fuzzy fingerprint images collected multiple times by the fingerprint collecting module 74 .

[0109] Specifically, the user's fuzzy fingerprint image is collected by the fingerprint collection module 74 (see Figure 5 shown). After M times of collection, M fuzzy fingerprint images are obtained. The receiving module 700 receives M fuzzy fingerprint images from the fingerprint collection module 74 .

[0110] Calculation module 702, configured to calculate the feature vector of each fuzzy fingerprint image.

[0111] Specifically, after the receiving module 700 receives the M fuzzy fingerprint images...

Abstract

The invention discloses a fingerprint simulation method and a corresponding mobile terminal, belonging to the technical field of fingerprint identification. The method includes: collecting fuzzy fingerprint images of users multiple times; calculating feature vectors of each of the fuzzy fingerprint images; dividing the calculated feature vectors into test set A and training set B according to a preset ratio; using Wiener The filter restoration algorithm processes the training set B to obtain the restored training set C; compares the test set A with the restored training set C to obtain a benchmark difference value as a judgment standard for subsequent fingerprint verification . As a result, the user can directly use the fingerprint recognition function of the mobile terminal more conveniently when the fingerprint is blurred.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint simulation method and a corresponding mobile terminal. Background technique [0002] At present, fingerprint identification technology has been changing with each passing day, and more and more mobile phones have integrated fingerprint identification systems. But, the fingerprint identification system in the existing mobile phone still has some functional defects. For example, assuming that there is a user whose fingerprint is blurred due to an accident, and the original complete fingerprint of the finger cannot be obtained. At this time, when the user is using the mobile phone, there is no way to use the fingerprint identification Function. Contents of the invention [0003] The main purpose of the present invention is to provide a fingerprint simulation method and a corresponding mobile terminal, aiming at solving the problem that it is diff...
