In some optional implementations, in terms of detecting whether the photographic subject falls within an iris recognition range of the mobile terminal, the processor is specifically configured to:
acquiring the distance between the shooting object and the mobile terminal and the facial posture of the shooting object based on the face image; detecting whether the distance between the shooting object and the mobile terminal falls into a preset distance range and whether the facial posture of the shooting object meets a preset facial posture condition; when the distance between the shooting object and the mobile terminal is detected to fall into a preset distance range and the facial posture of the shooting object meets a preset facial posture condition, the shooting object is detected to fall into the iris recognition range of the mobile terminal.

inquiring prompt information corresponding to the opening of the iris recognition mode; and outputting the prompt information, wherein the prompt information is used for prompting that the biological recognition mode which is started by the mobile terminal of the shooting object at present is an iris recognition mode.
Referring to fig. 2, fig. 2 is a schematic flow chart of an iris recognition mode starting method according to an embodiment of the present invention, and as shown in fig. 2, the iris recognition mode starting method according to the embodiment of the present invention includes the following steps:
s201, the mobile terminal acquires a face image corresponding to a shooting object in a shooting range of the mobile terminal;
s202, the mobile terminal detects whether the shot object falls into the iris recognition range of the mobile terminal or not based on the face image.
In the existing biometric identification mode, both the face identification mode and the iris identification mode belong to non-contact biometric identification technologies. For the face recognition mode, the distance between a face and a mobile terminal is generally required to be more than 10 cm and less than 70 cm, and the angle between the face and a camera of the mobile terminal is required to be less than 50 degrees; for the face recognition mode, the distance between the face and the mobile terminal is generally required to be greater than 20 centimeters and smaller than 40 centimeters, and the angle between the face and a camera of the mobile terminal is required to be smaller than 15 degrees. Therefore, the condition for turning on the iris recognition mode is satisfied, and the condition for turning on the face recognition mode is also satisfied. Although the iris recognition mode has a higher security level than the face recognition mode, the iris recognition mode requires less light than the face recognition mode because of the infrared supplementary lighting; moreover, the iris recognition mode requires the user to look directly at the camera for a longer time than the face recognition mode.
Here, a specific implementation manner of the mobile terminal detecting whether the photographic subject falls within the iris recognition range of the mobile terminal is as follows: the mobile terminal detects the distance between the photographic subject and the camera and whether the facial posture of the photographic subject (namely the angle between the photographic subject and the camera) falls within the iris recognition range.
S203, the mobile terminal starts an iris recognition mode when detecting that the shooting object falls into the iris recognition range of the mobile terminal and detecting that the face image meets a preset condition.
Specifically, when the mobile terminal detects that the shooting object falls into the iris recognition range of the mobile terminal, whether the obtained face image meets the preset condition or not can be continuously detected. Whether the face image meets the preset condition or not is detected, and then whether the mobile terminal is suitable for starting an iris recognition mode or a face recognition mode is judged.
And S204, otherwise, the mobile terminal starts a face recognition mode.
Therefore, the iris identification mode starting method provided by the embodiment of the invention has the advantages that the mobile terminal obtains the face image corresponding to the shooting object in the shooting range of the mobile terminal; detecting whether the shooting object falls into an iris recognition range of the mobile terminal or not based on the face image; the shooting object is detected to fall into the iris recognition range of the mobile terminal, and when the face image meets the preset condition, the iris recognition mode is started, so that the safety management diversity of the mobile terminal is promoted.
In some optional implementations, the mobile terminal may further perform the following operations:
detecting whether the system state of the mobile terminal meets a preset condition or not;
and when the system state of the mobile terminal is detected to meet the preset condition, executing the step of acquiring the face image corresponding to the shooting object in the shooting range of the mobile terminal.
Specifically, the detection that the system state of the mobile terminal satisfies the preset condition may be, for example, an unlocking request for a desktop, an unlocking request for an application, an unlocking request for a file, an authentication request for login, payment, and the like of a payment application, and is not limited herein. The desktop unlocking request refers to an unlocking request for locking a screen desktop; the unlocking request for the application refers to an unlocking request for specific operation of the application, such as application starting, application deleting and the like; the unlocking request for the file refers to an unlocking request for the file, such as an unlocking request for a target file; the authentication request for payment refers to an authentication request for payment of applications such as a payment bank and a mobile phone bank, for example, when the payment bank is used for payment and the mobile phone bank is used for transfer.
The unlocking request can be specifically triggered by touch operation, pressing operation, voice operation and the like of a user, and can also be triggered by a current interface of the mobile terminal, for example, if handheld operation of the mobile terminal in a screen-off standby state is detected, the unlocking request for a desktop can be understood to be detected; when the mobile terminal is in the payment interface, it may be understood that an authentication request for payment is detected, and the like, and the trigger condition is not limited herein.
In some optional implementations, a specific implementation manner of detecting whether the photographic subject falls within an iris recognition range of the mobile terminal may be:
acquiring the distance between the shooting object and the mobile terminal and the facial posture of the shooting object based on the face image;
detecting whether the distance between the shooting object and the mobile terminal falls into a preset distance range and whether the facial posture of the shooting object meets a preset facial posture condition;
when the distance between the shooting object and the mobile terminal is detected to fall into a preset distance range and the facial posture of the shooting object meets a preset facial posture condition, the shooting object is detected to fall into the iris recognition range of the mobile terminal.
The specific implementation manner of acquiring the facial pose of the photographic object based on the face image is as follows: and acquiring the angle of the shooting object relative to the mobile terminal.
In some optional implementation manners, a specific implementation manner of acquiring the face image corresponding to the photographic object within the shooting range of the mobile terminal may be:
acquiring at least two face images corresponding to the shot object within a preset time period;
the specific implementation manner of detecting that the face image meets the preset condition may be:
acquiring relative offset of pupils in the at least two face images based on the face images;
detecting whether the relative offset is smaller than a preset threshold value or not;
and when the relative offset is detected to be smaller than a preset threshold value, the detected face image meets a preset condition.
Specifically, the mobile terminal continuously acquires at least two face images within a preset time period (a short time), and if it is detected that the relative offset of the pupils of any two face images is greater than a preset threshold value in the at least two face images (as shown in fig. 2-1 and 2-2), it indicates that the line of sight of the shooting object is offset within the preset time period and does not look directly at the camera, so that the face images are not full of the preset condition and the iris recognition mode is not started. If the relative offset of the pupils of any two face images in the at least two face images is detected to be smaller than the preset threshold, the fact that the visual line of the shooting object is not obviously changed in the preset time period is indicated, and the camera is directly viewed (or approximately viewed as the direct view) so that the face images meet the preset condition, and the iris recognition mode is started.
The relative shift amount of the pupil may be a shift amount of the pupil with respect to the edge (corner) of the glasses to be photographed.
In some optional implementation manners, a specific implementation manner of detecting that the face image meets the preset condition may be:
acquiring environment information of an environment where the shooting object is located based on the face image, wherein the environment information comprises illumination information;
detecting whether the environment information meets the condition of starting an iris recognition mode;
and when the environment information is detected to meet the condition of starting the iris recognition mode, the face image is detected to meet the preset condition.
Specifically, the mobile terminal analyzes the illumination condition of the environment where the photographic object is located based on the acquired face image, and since the requirement on the illumination condition of the environment is weaker than that of the face recognition mode in iris recognition, the iris recognition mode is started when the illumination of the environment where the photographic object is located is detected to be smaller than a preset illumination intensity threshold. As shown in fig. 2-3, when it is detected that the illumination of the environment where the photographic subject is located is greater than a preset illumination intensity threshold, a facial recognition mode is started; as shown in fig. 2 to 4, when it is detected that the illumination of the environment where the photographic subject is located is less than the preset illumination intensity threshold, the iris recognition mode is turned on.
In some optional implementations, the mobile terminal may further perform the following operations:
inquiring prompt information corresponding to the opening of the iris recognition mode;
and outputting the prompt information, wherein the prompt information is used for prompting that the biological recognition mode which is started by the mobile terminal of the shooting object at present is an iris recognition mode.
After the mobile terminal starts the iris recognition mode, the mobile terminal can input prompt information corresponding to the start of the iris recognition mode so as to remind a user of biological recognition of which mode is required currently. The prompt information may be a vibration prompt, a ring prompt, or a color of a breathing light or a flashing number prompt light, which is not limited in the embodiments of the present invention.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating another iris recognition mode starting method according to an embodiment of the present invention, consistent with the embodiment shown in fig. 2. As shown in fig. 3, the method for starting an iris recognition mode in the embodiment of the present invention includes:
s301, the mobile terminal detects whether the system state of the mobile terminal meets a preset condition;
s302, when the mobile terminal detects that the system state of the mobile terminal meets a preset condition, the mobile terminal acquires a face image corresponding to the shot object;
s303, based on the face image, the mobile terminal obtains the distance between the shooting object and the mobile terminal and the face posture of the shooting object;
s304, the mobile terminal detects whether the distance between the shooting object and the mobile terminal falls into a preset distance range and whether the facial posture of the shooting object meets a preset facial posture condition;
s305, when the distance between the shooting object and the mobile terminal is detected to fall into a preset distance range and the facial posture of the shooting object meets a preset facial posture condition, the mobile terminal acquires the relative offset of pupils in the at least two facial images based on the facial images;
s306, the mobile terminal detects whether the relative offset is smaller than a preset threshold value;
s307, when the relative offset is detected to be smaller than a preset threshold value, the mobile terminal starts an iris recognition mode.
S308, the mobile terminal inquires prompt information corresponding to the opening of the iris recognition mode;
s309, the mobile terminal outputs the prompt information, and the prompt information is used for prompting the shooting object that the currently started biological recognition mode of the mobile terminal is the iris recognition mode.
