At present, there are many scenes that a user needs to record a face image by himself/herself using a terminal, for example, the scenes are used for verifying whether the face image of the user is acquired, unlocking the face of the terminal, and acquiring the face image of an entry person when some examinations are entered. In some scenes, the user needs to record the face image according to the specified requirements, such as a dot and a blink, a face needing to be within the specified range, and the like. Even in some scenarios, the user is required to record a face video for a period of time, and the user is required to perform different actions, such as nodding the head first and blinking the eye. In the case that the user is required to record the face video for a certain period of time, the user is sometimes required to perform some operation, for example, to perform the next operation. In order to enable a user to record a facial image meeting requirements quickly and accurately, the conventional terminal generally displays prompt information in the process of recording the facial image, for example: if the face of the user is recognized to be out of the specified range, prompt information of 'please place the face in a frame' is displayed.
However, for users with impaired vision (for example, near-sighted users), if the users need to remove vision aids or vision correction tools such as glasses during the recording process, the existing prompting method may cause that the users cannot obtain the prompting information within the distance range meeting the recording requirement, if the users are close to the terminal to watch the prompting information, other situations that the recording requirement is not met may occur, and the prompting information may also be changed, thereby increasing the difficulty of recording face images by users with impaired vision and prolonging the recording time.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of an information acquisition method according to an embodiment of the present invention, where the method is applied to a terminal, and includes:
step 11: the method comprises the steps that in the process of acquiring face information, a terminal determines whether the acquired face information meets a preset condition;
step 12: if the face information collected by the terminal does not meet the preset condition, the terminal determines whether the eyes of the user have visual impairment which causes the user to be incapable of acquiring at least part of information displayed on the terminal;
step 13: if the vision disorder exists in the eyes of the user, the terminal outputs first prompt information, and the first prompt information can be acquired by the user with the vision disorder, so that the acquired face information meets the preset condition.
In the embodiment of the invention, in the process of acquiring the face information, if the terminal determines that the eyes of the user have visual impairment (which easily causes the user to be unable to acquire the prompt information displayed on the terminal), the first prompt information aiming at the user with visual impairment is output under the condition that the acquired face information does not meet the preset condition, so that the user with visual impairment can acquire the prompt information (namely the first prompt information), and adjust the shooting posture and perform corresponding operation according to the prompt information, for example, the face is over against a camera, the relative position between the user and the terminal is adjusted so that the face in the acquired face image is located in a specified area, and a shooting completion confirmation button is clicked, and the like. Therefore, the user with visual impairment can quickly and accurately complete the human face information acquisition process according with the preset conditions.
The terminal may collect the face information by using a currently common visible light image collecting device, may also collect the face information by using an infrared image collecting device, or may collect the face information by using another face information collecting device, which is not limited herein. In addition, the preset condition may include at least one of: the human face needs to be in a designated area, the user needs to nod the head in the acquisition process, the user needs to shake the head in the acquisition process, the user needs to blink in the acquisition process and the like, and certainly, other preset conditions can be included, and the method is not exhaustive.
The above steps will be exemplified below.
In some embodiments of the invention, the step of determining whether the user's eyes have visual impairment which results in the user not being able to access at least part of the information displayed on the terminal comprises:
the terminal acquires the eye information of the user according to the acquired face information;
and the terminal determines whether the eyes of the user have visual disorder according to the eye information.
In the embodiment of the invention, in the process of acquiring the face information, the terminal can acquire the eye information of the user in real time according to the acquired face information, then accurately determine whether the eyes of the user have visual disorder according to the acquired eye information, and if the eyes of the user have visual disorder, output first prompt information aiming at the user with visual disorder when the acquired face information does not meet the preset conditions, so that the user with visual disorder can adjust the shooting posture and/or execute corresponding operations and the like according to the first prompt information, and further the face information acquired by the terminal meets the preset conditions.
Optionally, the step of obtaining the eye information of the user according to the collected face information includes:
the terminal acquires the eye information when the user wears the glasses and the eye information when the user does not wear the glasses;
the step of determining whether the vision disorder exists in the eyes of the user according to the eye information comprises the following steps:
and the terminal determines whether the eyes of the user have visual impairment according to the eye information when the user wears the glasses and the eye information when the user does not wear the glasses.
Further optionally, the eye information includes:
the size information of the user pupil can be specifically area or diameter;
and/or the presence of a gas in the gas,
information of a maximum distance between upper and lower eyelids or information of an area enclosed by the upper and lower eyelids.
As shown in FIG. 2, in the human eye, the cornea has positive spherical aberration, the lens has negative spherical aberration, and the two spherical aberrations neutralize each other, so that the light can generate a sharp focus and a clear image on the retina. The positive spherical aberration generated by the cornea itself remains basically unchanged in the life of a person, but the lens cannot be completely freely adjusted in a near-sighted state, as shown in fig. 3, the positive spherical aberration of the cornea and the negative spherical aberration of the lens cannot be counteracted, objects at a far distance are blurred, the lens is adjusted through the pupil, and the size of the pupil influences the adjusting function of the lens. Under the state of myopia, the pupil is enlarged, the lens spherical aberration is reduced, and the negative spherical aberration is increased; the pupil is reduced, the spherical aberration of the lens is increased, and the negative spherical aberration is reduced, so that the pupil is reduced within a certain limit for more clearly seeing objects after the glasses are taken off. Therefore, when the face information is collected, if it is detected that the user wears glasses, as shown in fig. 4, a polygon close to the area of the front view of the pupil is formed by selecting enough points at the edge of the pupil and connecting adjacent points, and then the actual area of the polygon is calculated as the actual area of the pupil according to the spatial depth information (i.e., the depth of field) (denoted as S1). And then, if the fact that the user removes the glasses is detected, calculating the actual area (marked as S2) of the pupil of the user after the user removes the glasses by the same method, finally calculating the difference value between S1 and S2, and if the difference value exceeds a certain threshold value, determining that the eyes of the user are short-sighted. In order to improve the accuracy, the actual pupil area of the user wearing the glasses may be obtained multiple times, and then the weighted average value is taken as S1, and similarly, the actual pupil area of the user with the glasses removed may be obtained multiple times, and then the weighted average value is taken as S2.
In addition, if the glasses are taken off by the myopic people when the glasses are worn, the myopic people can squint the eyes to see in order to see surrounding fuzzy objects clearly, and at the moment, light rays entering the eyes are reduced, so that some useless light rays are shielded. Therefore, whether the user is near-sighted can be determined by detecting the distance between the upper eyelid and the lower eyelid when the user wears the glasses and does not wear the glasses or the difference value of the enclosed areas of the upper eyelid and the lower eyelid. Specifically, referring to the method for measuring the pupil area, the shape of the eye of the user wearing glasses and the shape of the eye of the user removing glasses are described by selecting enough points on the edge of the eyelid and connecting adjacent points, then the maximum distance between the upper eyelid and the lower eyelid or the enclosed area is calculated according to the spatial depth information, finally the difference between the maximum distance between the upper eyelid and the lower eyelid of the user wearing glasses and the upper eyelid with glasses removed or the enclosed area is calculated, and when the difference is greater than a certain threshold, the myopia of the user is determined. For example, if the difference between the maximum distance between the upper and lower eyelids when the user wears the glasses and after the glasses are removed is 1mm or more, it is determined that the user's eyes are myopic.
In still other embodiments of the present invention, the step of determining whether the user's eye has a vision disorder comprises:
the terminal determines whether the user wears the glasses and then takes off the glasses according to the acquired face information;
if the user wears the glasses and then takes off the glasses, the terminal determines that the eyes of the user have visual disorder.
That is, if it is detected in the process of recording the face image that the user wears the glasses at first and then takes off the glasses, it is determined that the eyes of the user are visually impaired, and in the case that the prompt information needs to be output, the first prompt information for the visually impaired user should be output. The method for determining whether the eyes of the user have visual impairment is simple, the calculation complexity is low, and the calculation burden of a processor can be reduced.
In other embodiments of the present invention, the step of determining whether the user's eyes have visual impairment comprises:
the terminal acquires the setting information of a user;
and the terminal determines whether the eyes of the user have visual impairment according to the setting information.
That is, the terminal may provide a setting item for the user to select whether there is a vision disorder (e.g., myopia), and if the user selects that there is a vision disorder, the terminal outputs the first prompt information for the vision disorder user if the prompt information needs to be output. Specifically, the user may set whether there is visual impairment before starting to collect the face information, or may set whether there is visual impairment in the process of collecting the face information. The method for judging whether the user has the visual disorder is simpler, the calculation complexity is further reduced, and the method is not limited by whether the user wears glasses or not.
Optionally, the first prompt message includes: text information; the step of outputting the first prompt message includes:
displaying the character information on a display screen of the terminal by adopting a specified character size;
and/or the presence of a gas in the gas,
the first prompt message comprises: audio information; the step of outputting the first prompt message includes:
and broadcasting the audio information.
When the first prompt message comprises text information, the character size of the text information displayed on the display screen of the terminal is larger.
Optionally, after the step of determining whether the user's eyes have visual impairment that causes the user to be unable to acquire at least part of the information displayed on the terminal, the method further includes: and if the eyes of the user do not have vision disorder, outputting second prompt information, wherein the second prompt information cannot be acquired by the user with the vision disorder but can be acquired by the user without the vision disorder. The second prompt message also includes the character message, but the character size of the second prompt message is smaller than that of the character message of the first prompt message. For example, the side length (or area) of the font of the text information of the first hint information is 1.5 times or 2 times the font of the second hint information.
The second embodiment of the invention provides an information acquisition method, which comprises the following steps:
the first step is as follows: in the process of acquiring the face information, the terminal determines whether the acquired face information meets preset conditions, for example, whether the face is in a preset range, and whether actions such as nodding, shaking, blinking and the like exist.
The second step is that: and under the condition that the collected face information does not accord with the preset condition, the terminal acquires the eye information of the user according to the collected face information.
The third step: the terminal determines whether the user wears the glasses before and does not wear the glasses (takes off the glasses) according to the obtained eye information of the user.
The fourth step: when the user wears glasses first and then does not wear glasses, the areas of the pupils (the diameter of the pupils, the maximum distance between the upper and lower eyelids of the user, or the area enclosed by the upper and lower eyelids) of the user when wearing glasses and when not wearing glasses are obtained respectively.
The fifth step: if the area of the pupil of the user is obtained when the user wears the glasses and when the user does not wear the glasses, the difference value between the area of the pupil of the user when the user wears the glasses and the area of the pupil of the user when the user does not wear the glasses is obtained (if the diameter of the pupil, the maximum distance between the upper eyelid and the lower eyelid of the user or the area enclosed by the upper eyelid and the lower eyelid is obtained, the difference value between the value when the user wears the glasses and the value when the user does not wear the glasses is also calculated).
And a sixth step: and if the difference calculated in the fifth step is larger than a preset threshold, determining that the eyes of the user have visual disorder, wherein the value of the preset threshold can be obtained according to big data statistics. Of course, if the pupil diameter of the user, the maximum distance between the upper and lower eyelids of the user, or the enclosed area of the upper and lower eyelids is obtained, the preset threshold value needs to be adjusted accordingly.
The seventh step: under the condition that the vision disorder of the eyes of the user is determined, outputting first prompt information; and in the case that the user is determined that the vision disorder does not exist in the eyes of the user, outputting second prompt information. The second prompt message only comprises character messages, the first prompt message not only comprises the character messages but also comprises audio information, and the character size of the character messages of the first prompt message is larger than that of the character messages of the second prompt message.
