For example, fingerprint identification technology has become the standard matching of the flagship model of the mainstream mobile terminal manufacturer. The fingerprint identification process comprises the following steps: extracting features, saving data and image matching. After the original fingerprint image of the human fingerprint is read by the fingerprint identification module, the characteristic point matching is carried out on the fingerprint image and a pre-stored registered fingerprint template; and unlocking after the matching is successful.
The speed of the unlocking time directly affects the efficiency of the user for using the equipment, and the speed of the unlocking time becomes a bright point of product competition of various manufacturers at present, and how to shorten the unlocking time so as to improve the unlocking efficiency is an important direction for the research of technicians in the field.

The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
In order to better understand the unlocking control method and the mobile terminal disclosed in the embodiments of the present invention, the embodiments of the present invention are described in detail below.
Referring to fig. 1, fig. 1 is a diagram illustrating a fingerprint unlocking control method according to an embodiment of the present invention, where the fingerprint unlocking control method includes:
s101, when the mobile terminal detects touch operation of a fingerprint identification module aiming at the mobile terminal, judging whether the current time is in a preset quick unlocking time period;
the current time may be a system time of the mobile terminal, the mobile terminal is in a screen-off state or a screen-on and screen-locking state, and the preset fast unlocking time period may be, for example, 6 to 7 am, 7 to 8 am, and the like. In specific implementation, before the mobile terminal detects a touch operation of the fingerprint identification module for the mobile terminal, the mobile terminal may determine a preset fast unlocking time period through, for example, the following two schemes.
Firstly, the mobile terminal counts a historical time period when the mobile terminal is successfully unlocked, and determines a time period in which the number of times of successful unlocking in the historical time period is greater than a preset threshold value as a preset quick unlocking time period;
in a specific implementation, the mobile terminal may count time periods corresponding to successful unlocking of the mobile terminal in a preset time range such as one month and one quarter, where the time periods corresponding to successful unlocking in three months are shown in the following table:
if the preset threshold is 120, the mobile terminal can determine that the preset quick unlocking time period is as follows:
the time period set is composed of time periods "6 to 7", "11 to 12", "12 to 13", "17 to 18", and "22 to 23".
Secondly, the mobile terminal acquires quick unlocking time period setting information and determines the unlocking time period contained in the quick unlocking time period setting information as the preset quick unlocking time period.
In a specific implementation, the mobile terminal may display a setting interface for setting a preset fast unlocking time period on the display screen, and provide a time period drop-down list for the user to select, thereby determining the unlocking time period included in the generated time period setting information as the preset fast unlocking time period. Of course, the implementation manner of the mobile terminal acquiring the quick unlocking time period setting information may be various, and the embodiment of the present invention is not limited uniquely.
In the two ways of determining the preset quick unlocking time period, the former way of using machine learning is automatically completed, and after the historical time periods are accumulated, the successful times of screen-off fingerprint unlocking in different historical time periods can be accurately determined, so that the method is accurate and convenient; in the latter mode, the user can set specific time intervals which are regarded as the preset quick unlocking time intervals, so that the user subjective cognition can be better embodied, and the method is more suitable for certain specific users. The two implementation manners are both used for determining that the mobile terminal is considered to be an application environment with higher frequency when the user uses the mobile terminal in some time period, and accordingly the faster unlocking control method provided by the embodiment of the invention can be used for improving the user experience; if other ways are adopted to achieve the technical purpose, the implementation of the embodiment of the present invention is not affected, and therefore the above examples should not be construed as the only limitations to the embodiment of the present invention.
S102, if the current time is in the preset quick unlocking time period, the mobile terminal acquires fingerprint data, generates a fingerprint image according to the fingerprint data, extracts the characteristic points of the local image of the fingerprint image, and compares the characteristic points with a reference fingerprint template;
it can be understood that the specific implementation manner of the above-mentioned mobile terminal acquiring the fingerprint data may be various, and the embodiment of the present invention is not limited only.
In an embodiment, a specific implementation manner of the mobile terminal acquiring the fingerprint data is as follows:
the mobile terminal obtains n bottom layer data values through n induction electrodes of the fingerprint identification module, the n bottom layer data values are the fingerprint data, and n is a positive integer.
In another embodiment, the specific implementation manner of the mobile terminal acquiring the fingerprint data is as follows:
the mobile terminal passes through n2 bottom data values are obtained to n2 normal response electrodes of fingerprint identification module, n2 bottom data values are fingerprint data, the response electrode array of fingerprint identification module includes n1 unusual response electrodes with n2 normal response electrodes, n1, n2 are positive integer.
In a specific implementation, the implementation manner of generating the fingerprint image by the mobile terminal according to the fingerprint data is as follows:
determining n1 reference bottom layer data values corresponding to n1 abnormal sensing electrodes according to n2 bottom layer data values acquired by n2 normal sensing electrodes of the fingerprint identification module;
generating a fingerprint image from the n2 underlying data values and the n1 reference underlying data values.
The implementation manner of determining the n1 reference bottom layer data values corresponding to the n1 abnormal sensing electrodes according to the n2 bottom layer data values acquired by the n2 normal sensing electrodes of the fingerprint identification module is as follows:
determining an average of the n2 underlying data values;
and determining n1 reference bottom layer data values corresponding to the n1 abnormal sensing electrodes as the average value.
Or,
acquiring coordinate values of each abnormal induction electrode in n1 abnormal induction electrodes;
performing an average processing on each abnormal sensing electrode according to the coordinate value of each abnormal sensing electrode and the n2 underlying data values to obtain n1 reference underlying data values corresponding to n1 abnormal sensing electrodes;
the averaging process includes: determining x sensing electrodes of which the distance from the coordinate value of the abnormal sensing electrode processed by the current mean value is smaller than a preset distance in the n2 normal sensing electrodes, calculating the mean value of x bottom layer data values corresponding to the x sensing electrodes, and determining that the mean value is the reference bottom layer data value of the abnormal sensing electrode processed by the current mean value, wherein x is a positive integer.
S103, if the matching of the characteristic point and the reference fingerprint template is successful, the mobile terminal is unlocked.
The unlocking method of the mobile terminal comprises the following implementation modes:
loading a system application desktop of the mobile terminal; or,
loading an application interface of an application interrupted by the previous screen-off operation of the mobile terminal; or,
and loading an application interface of a preset application associated with the fingerprint data.
It can be seen that, in the embodiment of the present invention, when detecting that the system time of the user touching the fingerprint identification module is in the preset fast unlocking time period, the mobile terminal can acquire the fingerprint data, generate the fingerprint image according to the fingerprint data, extract the feature points of the local image of the fingerprint image, compare the feature points with the reference fingerprint template, and finally unlock the mobile terminal when the matching is successfully compared.
Optionally, in the embodiment of the present invention, the reference fingerprint template includes all feature point data or part of feature point data of a reference fingerprint image that is acquired and set in advance.
Optionally, in this embodiment of the present invention, after generating the fingerprint image according to the fingerprint data, the mobile terminal further performs the following operations:
and the mobile terminal cuts the fingerprint image according to a preset image cutting strategy to obtain a local image of the fingerprint image.
The preset image clipping policy may be, for example, an edge-first clipping policy, that is, preferentially clipping edge pixel points of a fingerprint image. If the fingerprint image comprises 1800 pixel points, the area of the pixel region corresponding to each pixel point is the same, the outermost insulating layer of the fingerprint image comprises 200 pixel points, the second outer edge layer comprises 160 pixel points, if the area ratio of the local image to the fingerprint image is preset to be 0.8:1, 360 pixel points need to be cut out, the mobile terminal can cut out 360 pixel points of the outermost edge layer and the second outer edge layer of the fingerprint image according to an edge priority cutting strategy, and therefore the local image of the fingerprint image is obtained. Obviously, the number of pixel points contained in the cut local graph is reduced, and the corresponding feature point information is also reduced.
