Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without any inventive step, are within the scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a control method of a mobile terminal according to an embodiment of the present invention, and is applied to a mobile terminal having a first biometric unlocking function and a second biometric unlocking function, as shown in fig. 1, including the following steps:
step 101, if a first biological characteristic which is input by a user and used for a first biological characteristic identification unlocking function is received, acquiring a target image of the first biological characteristic input this time.
In the embodiment of the present invention, if the currently-started biometric unlocking function of the mobile terminal is the first biometric unlocking function, the mobile terminal may receive the first biometric used for the first biometric unlocking function, and acquire the first biometric input this time, that is, the received image of the first biometric, as the target image.
For example: if the currently started biometric feature recognition unlocking function of the mobile terminal is the fingerprint recognition unlocking function, when the mobile terminal receives a fingerprint input by a user, the mobile terminal can acquire an image of the fingerprint input by the user as the target image.
The first biometric unlocking function may be any function that unlocks the mobile terminal by biometric identification such as fingerprint identification, face identification, iris identification, and the like, and is not limited herein.
And 102, determining an unlocking accuracy evaluation value of the first biological feature recognition unlocking function based on the target image.
In this embodiment of the present invention, if the target image is obtained in step 101, the mobile terminal may determine, based on the target image, an unlocking accuracy evaluation value in the current input with the first biometric unlocking function, so that the mobile terminal may obtain, each time the input biometric is received, an unlocking accuracy evaluation value when the currently-turned-on biometric unlocking function receives the input.
The unlocking accuracy evaluation value is any value which can represent the accuracy of identifying the first biological characteristic input by the user to realize unlocking when the mobile terminal receives the input. For example: if the target image is a fingerprint image, the mobile terminal may segment the grain image in the fingerprint image and the images except the grain image by an image segmentation method, determine the grain image as a foreground image, determine the images except the grain image as a background image, and calculate the definition of the foreground image and the definition of the background image.
Step 103, if the unlocking accuracy evaluation value of the first biometric unlocking function is smaller than or equal to the unlocking accuracy evaluation value of the second biometric unlocking function, controlling the currently started biometric unlocking function of the mobile terminal, and switching the first biometric unlocking function to the second biometric unlocking function.
In an embodiment of the present invention, if the step 102 determines the evaluation value of the unlocking accuracy of the first biometric unlocking function, the mobile terminal may compare the evaluation value of the unlocking accuracy of the first biometric unlocking function with the evaluation value of the unlocking accuracy of the second biometric unlocking function, and if the evaluation value of the unlocking accuracy of the first biometric unlocking function is less than or equal to the evaluation value of the unlocking accuracy of the second biometric unlocking function, the mobile terminal may control the currently-opened biometric unlocking function, and switch the first biometric unlocking function to the second biometric unlocking function.
For example: if the first biometric unlocking function is a fingerprint unlocking function, the second biometric unlocking function is a face unlocking function, and the mobile terminal determines that the unlocking accuracy evaluation value of the input fingerprint unlocking function is greater than or equal to the current unlocking accuracy evaluation value of the face unlocking function, the mobile terminal switches the currently-started biometric unlocking function to the face unlocking function.
The second biometric unlocking function is any biometric unlocking function of the mobile terminal except the first biometric unlocking function, and one biometric unlocking function is closed when the other biometric unlocking function is opened.
In addition, the evaluation value of the unlocking accuracy of the second biometric unlocking function is the evaluation value of the unlocking accuracy of the second biometric unlocking function determined when the mobile terminal starts the second biometric unlocking function before the current time and receives the second biometric used for the second biometric unlocking function last time. Of course, if the mobile terminal does not receive the second biometric input by the user before the current time and used for the second biometric unlocking function, the unlocking accuracy evaluation value of the second biometric unlocking function may be an initial unlocking accuracy evaluation value of the second biometric unlocking function set in advance.
In this embodiment of the present invention, the mobile terminal may be any mobile terminal having at least two biometric unlocking functions, for example: a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
In the control method of the mobile terminal in the embodiment of the invention, if a first biological characteristic which is input by a user and used for a first biological characteristic identification unlocking function is received, a target image of the input first biological characteristic is obtained; determining an unlocking accuracy evaluation value of the first biological feature recognition unlocking function based on the target image; and if the unlocking accuracy evaluation value of the first biological feature recognition unlocking function is smaller than or equal to the unlocking accuracy evaluation value of the second biological feature recognition unlocking function, controlling the currently started biological feature recognition unlocking function of the mobile terminal, and switching the first biological feature recognition unlocking function to the second biological feature recognition unlocking function. Therefore, the mobile terminal can switch the currently opened biological characteristic identification unlocking function in time according to the unlocking accuracy evaluation value of each biological characteristic identification unlocking function, so that the identification accuracy of the biological characteristics is high during unlocking, the identification accuracy is not required to be improved by simultaneously opening various biological characteristic identification unlocking functions, and the power consumption of the battery is reduced.
Referring to fig. 2, fig. 2 is a flowchart illustrating a control method of a mobile terminal according to an embodiment of the present invention, as shown in fig. 2, including the following steps:
step 201, if a first biological characteristic input by a user and used for a first biological characteristic recognition unlocking function is received, acquiring a target image of the first biological characteristic input this time.
The implementation process and beneficial effects of this step can be referred to the description in step 101, and are not described herein again.
Step 202, calculating the image matching degree of the target image and the pre-recorded image.
In this embodiment of the present invention, if the target image is obtained in step 201, the mobile terminal may perform feature matching on the target image and a pre-recorded image through an image recognition technology, and calculate an image matching degree between the target image and the pre-recorded image. The pre-recorded image is an image pre-stored in the mobile terminal, and may be an image of a fingerprint for configuring the fingerprint identification unlocking function, which is received by the mobile terminal and input by a user, or an image of a fingerprint for configuring the fingerprint identification unlocking function, which is received by the mobile terminal last time and input by the user, and the like.
For example: if the target image is a fingerprint image, the mobile terminal can perform fingerprint feature matching on the fingerprint image and a pre-recorded fingerprint image through an image matching technology, and calculate the image matching degree between the fingerprint image and the pre-recorded fingerprint image.
It should be noted that, the above-mentioned mobile terminal performs feature matching on the two images through an image recognition technology, and calculates a process of obtaining an image matching degree between the two images, which is well known to those skilled in the art and will not be described herein again.
And step 203, determining an unlocking accuracy evaluation value of the first biological feature recognition unlocking function according to the image matching degree.
In this embodiment of the present invention, if the image matching degree between the target image and the pre-recorded image is obtained in step 202, the mobile terminal may determine the unlocking accuracy evaluation value of the first biometric unlocking function when the current input is received according to the image matching degree.
The unlocking accuracy evaluation value of the first biometric unlocking function determined according to the image matching degree when the input is received may be an initial unlocking accuracy evaluation value of each biometric unlocking function stored in the mobile terminal, and the product of the initial unlocking accuracy of the first biometric unlocking function and the image matching degree is determined by the mobile terminal as the unlocking accuracy evaluation value, which may be set according to the user requirement.
For example: if the first biometric unlocking function is a fingerprint unlocking function and the image matching degree is 90%, and if the initial unlocking accuracy of the fingerprint unlocking function is 90%, the mobile terminal determines that the unlocking accuracy evaluation value is 81.
Optionally, before step 201, the method may further include: receiving a first biometric input by a user for configuring a first biometric unlocking function; determining an image including a first biometric feature for configuring a first biometric feature recognition unlocking function as a pre-recorded image; and determining an initial unlocking accuracy evaluation value of the first biological characteristic identification unlocking function according to the image quality of the pre-recorded image.
In this embodiment, when configuring the first biometric unlocking function, if receiving a first biometric feature input by a user and used for configuring the first biometric unlocking function, the mobile terminal may determine the received image of the first biometric feature as a pre-recorded image, so that when the biometric unlocking function currently started by the mobile terminal is the first biometric unlocking function, the matching degree between the pre-recorded image and the target image is calculated, so that reference targets for calculating the unlocking accuracy evaluation value are consistent, and the accuracy of the unlocking accuracy evaluation value is improved; in addition, an initial unlocking accuracy evaluation value of the first biological feature recognition unlocking function is determined according to the image quality of the pre-recorded image, so that the obtained initial unlocking accuracy evaluation value is more referential, and the operation is convenient and time-saving.
The determining of the initial unlocking accuracy evaluation value of the first biometric authentication unlocking function according to the image quality of the pre-recorded image may be that the mobile terminal evaluates the pre-recorded image according to the image quality and the image information amount respectively through an image processing technology, and determines an evaluation value obtained according to the image quality of the pre-recorded image and a comprehensive value of evaluation values obtained according to the image information amount of the pre-recorded image as the initial unlocking accuracy evaluation value.
For example: taking a pre-recorded image as a fingerprint image as an example, the mobile terminal can compare the definition of the fingerprint image with the definition of a preset reference image by adopting an image processing technology, calculate to obtain a definition ratio, and take the product of the definition ratio and a reference evaluation value as an evaluation value of the image quality of the fingerprint image; and using a preset value of the grain characteristics of the fingerprint in the fingerprint image as an evaluation value of the image information amount of the fingerprint image, such as a preset evaluation value of 48 when the fingerprint grain is annular, a preset evaluation value of 45 when the fingerprint grain is arcuate, and a preset evaluation value of 42 when the fingerprint grain is spiral, thereby using the sum of the evaluation value of the image quality of the fingerprint image and the evaluation value of the image information amount as an initial unlocking accuracy evaluation value thereof, such as a definition ratio of 0.9, a reference evaluation value of 50, and an annular fingerprint grain, thereby obtaining an initial unlocking accuracy evaluation value of 93.
It should be noted that the mobile terminal may configure the plurality of biometric unlocking functions, respectively obtain the pre-entered images and the initial unlocking accuracy evaluation values of the plurality of biometric unlocking functions, and use the biometric unlocking function with the highest initial unlocking accuracy evaluation value as the biometric unlocking function that is started first.
Further optionally, step 203 may include: determining an unlocking accuracy evaluation value of the first biological characteristic identification unlocking function according to the image matching degree and the initial unlocking accuracy evaluation value of the first biological characteristic identification unlocking function; or determining the unlocking accuracy evaluation value of the current first biological feature recognition unlocking function according to the image matching degree and the last determined unlocking accuracy evaluation value of the first biological feature recognition unlocking function.
In this embodiment, the unlocking accuracy evaluation value of the first biometric unlocking function is determined according to the image matching degree and the initial unlocking accuracy evaluation value of the first biometric unlocking function, and the product of the image matching degree and the initial unlocking accuracy evaluation value may be used as the unlocking accuracy evaluation value of the first biometric unlocking function by the mobile terminal, so that the complexity of calculation is low, and the efficiency of acquiring the unlocking accuracy evaluation value of the first biometric unlocking function by the mobile terminal is improved.
For example: if the first biometric unlocking function is a fingerprint unlocking function, the initial unlocking accuracy evaluation value is determined to be 95 through the pre-recorded image of the fingerprint unlocking function, and the matching degree between the target image and the pre-recorded image is 96%, the mobile terminal can acquire the unlocking accuracy evaluation value of the fingerprint unlocking function of this time to be 91.2.
In addition, the unlocking accuracy evaluation value of the current first biometric unlocking function is determined according to the image matching degree and the last determined unlocking accuracy evaluation value of the first biometric unlocking function, and the mobile terminal may determine the product of the image matching degree and the last determined unlocking accuracy evaluation value of the first biometric unlocking function as the current unlocking accuracy evaluation value of the first biometric unlocking function, so that the association exists between the current unlocking accuracy evaluation value of the first biometric unlocking function and the last determined unlocking accuracy evaluation value of the first biometric unlocking function, and the current unlocking accuracy evaluation value of the first biometric unlocking function is more accurate.
For example: if the previously determined unlocking accuracy evaluation value of the fingerprint identification unlocking function is 90% and the above image matching degree is 98%, the mobile terminal may determine that the unlocking accuracy evaluation value of the present fingerprint identification unlocking function is 88.2.
It should be noted that, if the first biometric feature received by the mobile terminal for the first biometric unlocking function at this time is the first biometric feature input by the user for the first time after the first biometric unlocking function is configured, the mobile terminal needs to determine the unlocking accuracy evaluation value of the first biometric unlocking function according to the image matching degree and the initial unlocking accuracy evaluation value of the first biometric unlocking function.
And 204, if the unlocking accuracy evaluation value of the first biological feature recognition unlocking function is smaller than or equal to the unlocking accuracy evaluation value of the second biological feature recognition unlocking function, controlling the currently started biological feature recognition unlocking function of the mobile terminal, and switching the first biological feature recognition unlocking function to the second biological feature recognition unlocking function.
The implementation process and beneficial effects of this step can be referred to the description in step 101, and are not described herein again. Optionally, the first biometric unlocking function and the second biometric unlocking function are any two of a fingerprint unlocking function, a face unlocking function, a palm unlocking function and an iris unlocking function, so that the diversity, safety and unlocking accuracy of the unlocking mode of the mobile terminal are improved.
The control method of the mobile terminal of the embodiment of the invention comprises the steps of calculating the image matching degree of the target image and the pre-recorded image; and determining the unlocking accuracy evaluation value of the first biological feature recognition unlocking function according to the image matching degree, so that the obtained unlocking accuracy evaluation value is more accurate, and the mobile terminal can switch the currently started biological feature recognition unlocking function more timely.
