The following describes an exemplary method for capturing an image through an optical accessory according to an embodiment of the present invention, taking a terminal device as an example.

The method for acquiring the image through the optical accessory provided by the embodiment of the invention can be applied to scenes in which a user needs to use the optical accessory to work.

Example one

As shown in fig. 1, an embodiment of the present invention provides a method for acquiring an image through an optical accessory, which may include the steps of:

101. a first distance between the optical accessory and the camera is detected.

In an embodiment of the present invention, the terminal device may detect a first distance between the optical accessory and the camera.

As shown in fig. 2, a schematic structural diagram of the terminal device before the optical accessory is connected, and as shown in fig. 3, a schematic structural diagram of the terminal device after the optical accessory is connected, a camera 22 and a flash 23 are disposed on a first surface 21 of the terminal device, and an optical accessory 24 is disposed on the first surface 21 outside the camera 22, so that the camera 22 can capture an image of the optical accessory 24. The first surface 21 is another surface of the terminal device where the display screen is located, that is, if the surface where the display screen is located is the front surface of the terminal device, the first surface 21 is the back surface.

It should be noted that the optical accessory is used for assisting the terminal device to perform operations, such as: the optical accessory can be a microscope, a magnifier, an external long lens and the like, and the embodiment of the invention is not limited.

It should be noted that the optical accessory is physically connected to the camera on the terminal device, such as: the optical accessory and the camera can be connected through the magnet, the magnet is arranged in the optical accessory and the camera respectively, and when the optical accessory is close to the camera, the magnets in the optical accessory and the camera attract each other to realize the connection of the optical accessory and the camera; the optical accessory can be connected with the camera through a buckle, the base is arranged on the outer side of the camera, the buckle is arranged on the outer side of the optical accessory, and when the optical accessory is close to the camera, the buckle on the optical accessory can be buckled with the base on the camera, so that the optical accessory is connected with the camera.

Optionally, detecting the first distance between the optical accessory and the camera may include the following two optional implementations:

the implementation mode is as follows: if the camera is provided with the infrared distance sensor, the terminal equipment can control the infrared distance sensor to emit a first light pulse signal and receive a second light pulse signal obtained by reflecting the first light pulse signal; detecting the interval duration between the first optical pulse signal and the second optical pulse signal; and determining the distance between the optical accessory and the camera according to the interval duration and the speed of light.

It should be noted that the infrared distance sensor is one of the distance sensors, and is mostly applied to a terminal device. The infrared distance sensor detects the distance between obstacles by using the principle that infrared signals meet the obstacles at different distances and the reflection time is different. The infrared distance measuring sensor is provided with a pair of infrared signal transmitting and receiving diodes, the transmitting tube transmits an infrared signal with specific frequency, the receiving tube receives the infrared signal with the frequency, and when the detection direction of the infrared signal meets an obstacle, the infrared signal is reflected back to be received by the receiving tube.

Since infrared rays have a small refractive index when passing through other substances, they are not substantially diffused when they travel. When the infrared distance sensor is used for distance measurement, the distance can be calculated according to the time from sending to receiving of an infrared signal and the transmission speed of infrared rays, namely the round-trip transit time delta t of the infrared rays modulated by high frequency on the distance to be measured is utilized, and according to the transmission speed V of the infrared rays, a formula is combined

The distance D can be obtained.

Illustratively, when the optical accessory is close to the camera, a bundle of infrared ray can be launched to infrared distance sensor's in the camera transmitting tube, and this infrared ray is the rectilinear propagation in the air, when infrared ray touches optical accessory, will reflect, is received by infrared distance sensor's in the camera receiving tube. Assuming that the infrared distance sensor takes 0.32ns from the emission of infrared rays to the reception of reflected infrared rays, the propagation speed of the infrared rays in the air is 3 x 10⁸m/s, then substituting into the formula, can obtain

That is, it can be said that the distance between the camera and the optical accessory is 4.8 cm.

The implementation mode two is as follows: if the camera is provided with the Hall sensor and the optical accessory is provided with the magnet, the terminal equipment can acquire the magnetic field intensity between the optical accessory and the camera through the Hall sensor; and determining the distance between the optical accessory and the camera according to the magnetic field intensity.

It should be noted that the hall sensor uses the hall effect as the working principle, and is an integrated sensor composed of a hall element and an auxiliary circuit, and is used for detecting the magnitude of the magnetic field and the change of the magnetic field. The Hall semiconductor chip in the Hall sensor and the magnet generate a magnetic field, and under the action of the magnetic field, the constant current can be deviated when passing through the Hall semiconductor chip, so that Hall voltage is generated. The Hall voltage changes along with the change of the magnetic field intensity, and the stronger the magnetic field, the higher the voltage; the weaker the magnetic field, the lower the voltage.

For example, a magnetic field is generated between a hall sensor in the camera and a magnet in the optical accessory, so that the hall sensor in the camera can detect the magnetic field strength H and the current I between the hall sensor and the magnet through the hall effect, and then calculate the formula according to the magnetic field strength

The distance D between the optical accessory and the camera can be obtained through calculation, wherein K is a magnetic coefficient, is related to the magnet and is a fixed value.

102. And starting a target application program corresponding to the optical accessory on the terminal equipment.

In the embodiment of the present invention, if the first distance between the optical accessory and the camera is smaller than the first preset distance, the target application program corresponding to the optical accessory on the terminal device is started.

The first preset distance can be set in advance by the terminal device, and when the first distance is smaller than the first preset distance, it can be shown that the connection between the optical accessory and the camera is completed, and then the terminal device can start a target application program corresponding to the optical accessory on the terminal device.

The target application corresponds to the optical accessory. If the optical accessory is a microscope, then the target application may be a camera or microscope specific application; if the optical accessory is a magnifier, the target application may be a camera or magnifier-specific application; if the optical accessory is an external telephoto lens, the target application may be a camera.

Optionally, if a plurality of target applications corresponding to the optical accessory are provided on the terminal device, the terminal device may display application icons of the plurality of applications on the display screen, and output a prompt message for prompting the user to select a target application required by the user from the application icons of the plurality of applications, and the terminal device may respond to a touch operation of the user, determine an application corresponding to the application icon selected by the user as the target application, and start the target application.

For example, as shown in fig. 4, a sub-interface 41 is displayed in a display screen of the terminal device, and application icons 42 of a plurality of applications corresponding to the optical component are arranged and displayed in the sub-interface 41.

Optionally, the terminal device may also display application icons of the plurality of application programs in a floating manner on a display screen of the terminal device.

For example, assuming that the optical accessory is a microscope, the application corresponding to the microscope may include a system application (e.g., a camera application), and/or at least one third party application that may access a camera of the terminal device to acquire images. The terminal device may display the camera application and the at least one third party application on a display screen of the terminal device. Further, the terminal device may further display a prompt message "please select a desired application" to prompt the user to select, so that when the user clicks an application icon of a certain application, the terminal device may determine the certain application as a target application and start the certain application.

Further, when the terminal device displays application icons of a plurality of applications corresponding to the optical accessory, a search bar may be further provided so that the user can search for a target application in the search bar when the number of applications corresponding to the optical accessory is large.

For example, as shown in fig. 4, the terminal device may set a search bar 43, and the user may input an identifier (name, number, etc.) of the target application in the search bar 43 for searching the target application, so that when the number of applications corresponding to the optical accessory is large, the time for the user to search for the target application may be reduced.

Through the optional implementation mode, the terminal equipment can determine the target application program in a mode of outputting the prompt message to prompt the user to select from the plurality of application programs under the condition that the plurality of target application programs corresponding to the optical accessory exist, so that interaction between the terminal equipment and the user can be increased, operation can be performed according to the selection of the user, and the accuracy of the application program is improved.

Optionally, if a plurality of target applications corresponding to the optical accessory are provided on the terminal device, the method may further include: the terminal device acquires a history start record for a target application program, determines an application program which is started the most number of times after the optical accessory is connected as the target application program, and starts the target application program.

For example, assuming that the optical accessory is a microscope, the application corresponding to the microscope may be a camera and a miniature world, the miniature world may be connected to the camera, and the miniature world may display an image of the microscope captured by the camera. The terminal device may acquire a history start record for the camera and the mini-world, wherein the camera is started 4 times and the mini-world is started 15 times after the microscope is connected, and then the terminal device may determine the mini-world as the target application and start the mini-world application.

Through the optional implementation mode, the terminal device can select the application program with the largest starting times by acquiring the historical starting record to determine the target application program under the condition that a plurality of target application programs corresponding to the optical accessory exist, so that the terminal device can select the application program with the largest starting times according to the historical record, and the operation times of a user are reduced.

103. And acquiring an imaging picture of the optical accessory through the camera to obtain a target image, and displaying the target image in an interface of a target application program.

In the embodiment of the invention, after the optical accessory obtains the imaging picture, the terminal device can acquire the imaging picture of the optical accessory through the camera to obtain the target image, and the target image is displayed in the interface of the target application program.

The embodiment of the invention provides a method for acquiring an image through an optical accessory, wherein a camera is arranged on a first surface of a terminal device, the optical accessory is arranged on the outer side of the camera on the first surface, so that the camera acquires an imaging picture passing through the optical accessory, and the terminal device can detect a first distance between the optical accessory and the camera; if the first distance is smaller than the first preset distance, starting a target application program corresponding to the optical accessory on the terminal equipment; and acquiring an imaging picture of the optical accessory through the camera to obtain a target image, and displaying the target image in an interface of a target application program. Through the technical scheme, the terminal equipment can automatically start the application program corresponding to the optical accessory without touch operation of a user when detecting that the distance between the optical accessory and the camera is smaller than the preset distance, so that the operation times of the user can be reduced, and a module for data transmission does not need to be configured in the optical accessory and the terminal equipment, so that the cost of the optical accessory and the terminal equipment is reduced; in addition, data transmission is carried out between the optical accessory and the terminal equipment in a communication connection mode, so that data can be prevented from being lost or stolen under the condition of unstable signals, and the data transmission efficiency is prevented from being slow under the condition of unstable signals.

Optionally, acquiring an imaging picture of the optical component to obtain the target image may specifically include: continuously acquiring imaging pictures of a plurality of frames of optical accessories; comparing the imaging pictures of the multi-frame optical accessory to obtain a comparison result; and when the resident abnormal display area exists in the imaging picture of the multi-frame optical assembly according to the comparison result, repairing the resident abnormal display area according to the normal display area of the imaging picture of each frame of optical assembly to obtain the target image.

The resident abnormal display area is the same abnormal display area with the frequency higher than the frequency threshold value in the imaging picture of the multi-frame optical accessory.

It should be noted that, for an abnormal display area caused by dirt/cracks on a camera or an abnormal display area caused by dirt/cracks on a screen area corresponding to a camera under a screen, a difference between pixel values of the abnormal display area and adjacent areas of the abnormal display area is generally relatively large, so that a terminal device may identify an edge of each image area in an imaging picture of an optical accessory through an edge identification algorithm, after determining the edge of the image area, may compare the pixel value of the edge of the image area with a pixel value of an adjacent pixel point outside the edge of the image area, and if the difference between the pixel value of the edge and the pixel value of the adjacent pixel point is greater than a preset threshold, determine that the image area in the edge is the abnormal display area.

Further, after determining that the resident abnormal display area exists in the imaging picture of the multi-frame optical assembly according to the comparison result, the terminal device may further: determining the size of an inscribed circle of the resident abnormal display area and the size of an circumscribed circle of the resident abnormal display area; calculating a first ratio of the size of the inscribed circle to the size of the circumscribed circle; if the first ratio is smaller than the first ratio threshold, determining that the resident abnormal display area is caused by damage of the camera, or caused by damage of a screen area corresponding to the camera; and if the first ratio is larger than or equal to the first ratio threshold, determining that the resident abnormal display area is caused by the dirt of the camera or the dirt of the screen area corresponding to the camera.

It should be noted that, because the resident abnormal display area caused by general dirt is close to a circle, the difference between the sizes of the inscribed circle and the circumscribed circle of the resident abnormal display area is small, the resident display area caused by damage to the camera or the screen area corresponding to the camera is close to a linear shape, and the difference between the sizes of the inscribed circle and the circumscribed circle of the resident abnormal display area is large. The size of the circle involved in the embodiment of the present invention may be the area, radius or diameter of the circle.

In this optional implementation manner, the terminal device may detect whether an abnormal display area exists in an imaging picture of the currently acquired optical accessory, and if so, repair the abnormal display area, so that the terminal device may acquire a normal imaging picture of the optical accessory, and the terminal device may determine a reason for causing the abnormal display according to size information of the abnormal display area, which is more favorable for repairing the terminal device.

Example two

As shown in fig. 5, an embodiment of the present invention provides a method for acquiring an image through an optical accessory, which may further include the steps of:

501. a first distance between the optical accessory and the camera is detected.

502. And starting a target application program corresponding to the optical accessory on the terminal equipment.

503. And acquiring an imaging picture of the optical accessory through the camera to obtain a target image, and displaying the target image in an interface of a target application program.

In the embodiment of the present invention, for the description of steps 501 to 503, please refer to the detailed description of steps 101 to 103 in the first embodiment, which is not repeated herein.

504. An average luminance value of the target image is detected.

In the embodiment of the present invention, the terminal device may detect an average brightness value of the target image, where the average brightness value may be an average value of brightness values of each pixel in the target image.

505. And turning on the flash lamp.

In the embodiment of the present invention, if the average brightness value of the target image is smaller than the standard brightness value, it may be said that the brightness value of the target image is lower, and then the terminal device may turn on the flash lamp, so that the brightness value of the image acquired by the terminal device is increased.

It should be noted that the flash is used for providing a light source in a dark environment, and in the embodiment of the present invention, as shown in fig. 2 and fig. 3, the flash 23 and the camera 22 are disposed on the first surface 21 of the terminal device, and the flash 23 is avoided when the optical accessory 24 is connected with the camera 22, so that the flash 23 is not covered by the optical accessory 24, so as to achieve the purpose of providing a light source.

Optionally, after the flash is turned on, the method may further include: the terminal equipment acquires a first image through a camera; when the presence of a facial feature in the first image is detected, the flash is turned off.

In this implementation manner, after the terminal device turns on the flash, the camera may be further controlled to capture a current first image, and the first image is identified, if it is detected that the facial feature exists in the first image, it may be indicated that the user is facing the camera, and similarly, the terminal device may turn off the flash.

Through this optional implementation, terminal equipment can close the flash light when detecting that there is facial feature in the image that the camera was gathered, namely when the user openly faces camera and flash light, can avoid the user to look directly the flash light of opening like this, avoids user's eyes to receive the harm.

506. And detecting the parameter information of the terminal equipment.

In the embodiment of the invention, after the terminal device turns on the flash lamp, the parameter information of the terminal device can be detected.

Wherein, the parameter information of the terminal equipment comprises: at least one of an orientation of the flash, a turn-on duration of the flash, and a second distance between the optical accessory and an object in the photographic environment.

It should be noted that the orientation of the flash may be detected by a gyroscope in the terminal device, and the second distance may be detected by an infrared distance sensor in the optical accessory.

Alternatively, the gyroscope is also called an angular velocity sensor, the gyroscope measures the angular velocity of the terminal device during the yaw and the tilt, and the gyroscope can represent the current pose of the terminal device by X, Y, Z three parameters, wherein X, Y, Z three parameters represent three directions respectively. When the terminal equipment is in a static state, X, Y, Z all have 0 parameters; when the user uses the terminal device to turn over, X, Y, Z three parameters will change, so the gyroscope can obtain the pose change of the terminal device according to the three parameters, and the orientation of the flash lamp on the terminal device is obtained.

507. And if the parameter information of the terminal equipment meets the preset condition, turning off the flash lamp.

In the embodiment of the invention, if the parameter information of the terminal equipment meets the preset condition, the terminal equipment can turn off the flash lamp.

Optionally, if the parameter information of the terminal device meets the preset condition, turning off the flash lamp may include the following three optional implementation manners:

the implementation mode is as follows: and if the included angle between the orientation of the flash lamp and the gravity direction is larger than the preset included angle, closing the flash lamp.

If the terminal device detects that the included angle between the orientation of the flash lamp and the gravity direction is larger than the preset included angle through the gyroscope, it can be shown that the irradiation direction of the flash lamp is not the gravity direction, and the flash lamp deflects, so that the terminal device can close the flash lamp.

Illustratively, the preset included angle is assumed to be 45 °. If the terminal device detects that the included angle between the orientation of the flashlight and the gravity direction is 69 degrees and 69 degrees is larger than 45 degrees through the gyroscope, the terminal device can turn off the flashlight.

The implementation mode two is as follows: and if the starting time of the flash lamp is longer than the preset time, the flash lamp is turned off.

If the terminal device detects that the starting duration of the flash lamp is longer than the preset duration, it can be shown that the flash lamp is started for a long time, and heating of the terminal device may be caused, so that the terminal device can close the flash lamp.

For example, assume that the preset time period is 30 minutes. If the terminal device detects that the on-time of the flash lamp reaches 32 minutes, and the 32 minutes is more than 30 minutes, the terminal device can turn off the flash lamp.

The implementation mode is three: and if the second distance is greater than the second preset distance, the flash lamp is turned off.

If the terminal device detects that the second distance between the optical accessory and the object in the shooting environment is larger than the second preset distance through the infrared distance sensor, it can be shown that the optical accessory and the flash lamp are exposed in the air, and the flash lamp may irradiate the eyes of the user, so that the terminal device can turn off the flash lamp.

Illustratively, assume that the second predetermined distance is 50 cm. If the terminal device detects that the second distance is 60cm through the infrared distance sensor, and the second distance is larger than 50cm, the terminal device can turn off the flash lamp.

The implementation mode is four: judging whether the second distance is greater than a second preset distance; if the second distance is greater than the second preset distance, judging whether an included angle between the orientation of the flash lamp and the gravity direction is greater than a preset included angle; if the included angle between the orientation of the flash lamp and the gravity direction is larger than the preset included angle, judging whether the starting time of the flash lamp is larger than the preset time; and if the starting time of the flash lamp is longer than the preset time, the flash lamp is turned off.

In this implementation manner, if the parameter information of the terminal device includes: the orientation of the flash lamp, the opening duration and the second distance of the flash lamp, then the terminal equipment can detect the parameter information of the terminal equipment according to the sequence, firstly judge whether the second distance is greater than the second preset distance, if the second distance is greater than the second preset distance, judge whether the orientation of the flash lamp and the included angle of the gravity direction are greater than the preset included angle, if the orientation of the flash lamp and the included angle of the gravity direction are greater than the preset included angle, judge whether the opening duration of the flash lamp is greater than the preset duration, if the opening duration of the flash lamp is greater than the preset duration, then the terminal equipment can close the flash lamp.

Through the four optional implementation modes, the terminal equipment can close the flash lamp when the parameter information of the terminal equipment meets the preset condition, so that the flash lamp can be prevented from irradiating eyes of a user, the eyes of the user can be prevented from being damaged, the flash lamp can be prevented from being started for a long time, and the terminal equipment can be heated for a long time.

The embodiment of the invention provides a method for acquiring an image through an optical accessory, wherein when detecting that the distance between the optical accessory and a camera is smaller than a preset distance, a terminal device can automatically start an application program corresponding to the optical accessory without touch operation of a user, so that the operation times of the user can be reduced, and a module for data transmission is not required to be configured in the optical accessory and the terminal device, so that the cost of the optical accessory and the terminal device is reduced; in addition, data transmission is carried out between the optical accessory and the terminal equipment in a communication connection mode, so that data can be prevented from being lost or stolen under the condition of unstable signals, and the data transmission efficiency is prevented from being slow under the condition of unstable signals; when the average brightness value of the target image is lower, the flash lamp is started so that the terminal equipment can acquire the image with the standard brightness value; when the parameter information of the terminal equipment meets the preset condition, the flash lamp is turned off, so that the flash lamp can be prevented from irradiating eyes of the user, the eyes of the user are damaged, the flash lamp can be prevented from being turned on for a long time, and the terminal equipment can be heated for a long time.

Optionally, after the terminal device displays the target image in the interface of the target application, the method may further include: and the terminal equipment identifies the target image, and if the target image is detected to have no effective object displayed, a prompt message is output and used for prompting a user to adjust the optical accessory.

It should be noted that, if the terminal device detects that the target image is blank or completely black, that is, there is no valid object in the target image, it can be stated that the optical accessory is not correctly connected or the parameters of the optical accessory are incorrect, and then the terminal device can prompt the user to adjust the optical accessory.

Wherein the parameters of the optical accessory may include: magnification of optical accessory, position of observed object, ambient brightness, etc.

Through the optional implementation mode, the terminal equipment can prompt a user to adjust the optical accessory when the target image is abnormal, so that a correct target image is obtained, the working efficiency of the optical accessory can be improved, and abnormal images are prevented from being acquired for many times.

Optionally, after the terminal device displays the target image in the interface of the target application, the method may further include: the terminal device detects target content of the target image, acquires learning content corresponding to the target content, acquires personal information of the user, and outputs the learning content matched with the personal information.

It should be noted that, if the user is a student, the user may need the optical accessory to perform a biological experiment or the like, such as observing a specimen. The terminal device may detect the target content of the target image and search for the learning content corresponding to the target content, where the learning content may include: content explanation, exercise, content expansion and the like; when the terminal device searches a plurality of learning contents, the terminal device may obtain personal information of the user, where the personal information at least includes: user age, user grade; the terminal device may display the learning content matching the user grade on a display screen of the terminal device.

The optional implementation manner can be applied to a scene that a user observes a specimen by using the optical accessory, the terminal device can search and display the searched related learning content according to the content of the specimen, and when the learning content comprises a plurality of learning contents, the terminal device can display the learning content matched with the grade of the user according to the grade information of the user. Therefore, the terminal equipment can further output the content related to the target image after acquiring the target image, so that the terminal equipment is more intelligent.

Optionally, before detecting the first distance between the optical accessory and the camera, the terminal device may further obtain a plurality of learning contents, and determine, in response to a touch operation of the user, a target learning content matched with the grade and the subject of the user; acquiring a current image through a camera, and if an object matched with target learning content is detected to exist in the current image, determining that an optical accessory is arranged on the outer side of the camera and a sample to be observed is placed correctly; if it is detected that an object matched with the target learning content does not exist in the current image, it can be determined that the optical accessory is connected with the camera wrongly or the sample to be observed is selected wrongly.

It should be noted that the optional implementation manner is suitable for determining, when it is not determined whether the optical accessory is connected to the camera, that the optical accessory is disposed outside the camera and the sample to be observed is correctly placed, and then the terminal device may perform all the steps of the embodiment of the present invention.

For example, assuming that the current grade of the user is one higher and the user is learning the content related to the chloroplast, the user can determine that the target learning content is the content related to the chloroplast in the higher creature through a touch operation. At this moment, the camera can acquire the current image, and detect that the chloroplast exists in the current image, so that the optical accessory can be determined to be arranged outside the camera, and the sample to be observed is the chloroplast sample.

Through this optional implementation, terminal equipment can confirm whether optical accessories and camera are connected correctly to can detect whether the user will wait to observe the sample selection and place correctly, make terminal equipment more intelligent.

Through the optional implementation mode, the terminal device can determine the current learning progress of the user, output related learning content and exercise questions to the user, and send the learning progress and the exercise question completion conditions to the parent device, so that parents can know the learning progress and the mastering conditions of the user.

Optionally, after the terminal device displays the target image in the interface of the target application, the method may further include: the terminal equipment detects a first angle between the terminal equipment and a horizontal plane through a gyroscope, if the first angle is within a preset angle range, a face image of a user is collected through a front camera, a second angle of the face of the user relative to the terminal equipment is calculated according to the face image of the user, a head lowering angle of the user is calculated according to the first angle and the second angle, if the head lowering angle is larger than a standard angle, a prompt message is output, and the prompt message is used for prompting the user to adjust the sitting posture.

Illustratively, the preset angle range is assumed to be 0 ° to 45 °, and the standard angle is 35 °. As shown in fig. 6, if the first angle of the terminal device 61 to the horizontal plane is 30 °, that is, angle a is 30 °, and is between 0 ° and 45 °, the terminal device 61 collects the user face image, and analyzes the user face image, and can obtain that the second angle of the user 62 relative to the terminal device 61 is 105 °, that is, angle D is 105 °, then by the sum of the internal angles of the triangle is 180 °, that is, angle B + C + angle D is 180 °, and because angle a and angle B are the same-position angles, angle B is 30 ° as well as angle C-30 ° -105 ° -55 °, that is, the low-angle of the user 62 is 55 °, 55 ° is greater than 35 °, it can be said that the sitting posture of the user 62 is incorrect, and at this time, the terminal device 61 can prompt the user 62 to adjust the sitting posture.

Through the optional implementation mode, the terminal equipment can acquire the deflection angle between the terminal equipment and the horizontal plane through the gyroscope, then the angle of the face of the user relative to the terminal equipment is obtained through analysis according to the face image of the user, and the head lowering angle of the user can be calculated according to the relation that the sight line of the user, the horizontal plane and the terminal equipment are triangular, so that the obtained head lowering angle of the user is accurate; when the head-lowering angle is larger than the preset angle, the user is prompted to adjust the sitting posture, so that the bad sitting posture of the user can be detected in time, and the terminal equipment is more humanized and intelligent.
