The television camera tracks and collects identity information of each user.
Step S20, determining the relative position information of the target user and the display screen;
specifically, in this embodiment, taking the television as the display terminal, the camera of the television reports the collected identity information of all users in front of the display screen to the television terminal. In addition, in order to avoid the situation that the intelligent adjustment of the display screen cannot achieve the expected effect caused by multiple target users, a single-person mode can be set. And in the single-person mode, according to the target user information captured by the external camera of the television, comparing the target user information with the target user information prestored in the television, locking the target user, and calculating the relative position information of the target user and the display screen.
And step S30, adjusting the visual angle of the display screen based on the relative position information.
Specifically, in this embodiment, the television MCU performs real-time processing according to the relative position of the collected target user and the display screen and the left and right data (if the moving position of the target user needs a certain limit, the difference is too small, and the camera may not be recognized, resulting in no response at the television end), and sends a command to the motor through the curved screen bending/base rotation control module, so as to automatically adjust the left-to-right rotation or the center position of the television base, adjust the curvature of the screen according to the distance between the target position and the television screen, where the curvature is large when the distance is close and small when the distance is far, and data processing here assumes that the user obtains the best and healthier viewing effect.

step S101, collecting image information of a plurality of users in front of a display screen;
specifically, in this embodiment, after the television is turned on to start the screen adjustment function of the smart television, the external camera of the television starts to capture the facial image of the user in front of the display screen, and it should be noted that if the smart television captures a plurality of facial images of the user at the same time, the facial feature information corresponding to the plurality of recognized facial images is distributed.
Step S102, determining one of the users as a target user.
Specifically, in the present embodiment, the television terminal identifies facial feature information of a plurality of users captured by the camera, where the facial feature information includes: the system comprises a terminal, a left eye characteristic information module, a right eye characteristic information module, a nose characteristic information module, a mouth characteristic information module, a face contour characteristic information module, a pupil characteristic information module and the like, wherein the face characteristic distribution of a plurality of users is compared with the face characteristic information of target users prestored in the terminal, and one of the users is determined to be the target user.
Further, referring to fig. 4, the step S102 further includes:
step S1021, comparing the image information of the plurality of users with the image information of a pre-stored target user;
specifically, in this embodiment, the television terminal uploads images captured by an external camera of the television terminal to a UI application layer of the television terminal, the UI application layer compares, one by one, the identity information of a target user, which is stored in the television terminal by the user in advance, with the acquired image information, and the user matched with the pre-stored identity information of the target user is taken as the target user; in order to embody the intelligence of the adjusting scheme of the viewing angle of the display screen to the greatest extent, in this embodiment, a single-target user mode is adopted, that is, if the multiple users captured by the television camera include multiple target users who already have pre-stored identity information in the television system, in this case, the television terminal determines a unique "target user" according to the relative position information of the multiple "target users" and the television. That is, the television terminal determines the "target user" whose position relative to the display screen is optimal as the target user.
Step S1022, determining a user matched with the pre-stored target user image information among the multiple users as a target user.
Specifically, in this embodiment, facial feature information of multiple users captured by an external camera of the television is compared with identity information of target users stored in advance in the television system, where the content of comparison includes, but is not limited to: left eye feature information, right eye feature information, nose feature information, mouth feature information, face contour feature information, and pupil feature information.
In this embodiment, when there are multiple users in front of the display screen, in order to make the intelligent adjustment effect of the display screen better, a single-user mode is adopted in this embodiment, and the user who stores the identity information in the terminal system in advance is determined as the target user, so that the display screen performs view angle adjustment according to the position information of the target user more intelligently and pertinently, and the target user has an exclusive optimal view angle.
Further, referring to fig. 5, a third embodiment of the method for adjusting the viewing angle of the display screen according to the present invention is proposed based on the above-mentioned embodiment, and in this embodiment, referring to fig. 5, the step S102: after tracking the position of the target user in front of the display screen, the method further comprises the following steps: step S103, judging whether the image information of the plurality of users is consistent with the image information of the pre-stored target user;
step S104, if yes, position information acquisition is carried out on the target user;
and step S105, if not, guiding the user to store the identity information.
Specifically, in this embodiment, for the facial image information of the current user on the display screen captured by the camera of the television, it is determined whether the facial image information of the current user matches the facial information of the target user pre-stored in the television system, and if the facial image information matches the facial information of the target user pre-stored in the television system, the position information of the current user is further acquired, so as to obtain the relative position relationship between the target user and the display screen; if the identity information does not match with the preset identity information, the television system does not have the identity information prestored by the user, a prompt box pops up, and the user is guided to acquire and store the identity information through the prompt box.
In the embodiment, image information of a plurality of users in front of a display screen is collected; determining one of the plurality of users as a target user; comparing the image information of the plurality of users with pre-stored target user image information; determining a user matched with the pre-stored target user image information in the plurality of users as a target user; judging whether the image information of the plurality of users is consistent with the image information of the pre-stored target user; if so, acquiring position information of the target user; and if not, guiding the user to store the identity information. Therefore, when a plurality of users exist in front of the display screen, the user with the pre-stored identity information is selected as the only target user, the intelligence of the adjustment of the display screen and the adaptability of the target user are effectively improved, and the optimal and healthier watching effect is provided for the target user to the maximum extent.
Further, referring to fig. 6, a fourth embodiment of the method for adjusting the viewing angle of the display screen according to the present invention is proposed based on the above-mentioned embodiment, and in this embodiment, referring to fig. 6, the step S20: determining the relative position information of the target user and the display screen further comprises:
step S201, collecting the current position information of the target user;
specifically, in this embodiment, still using the television set in embodiment 1 as an example of the display device, after the television system determines the target user watching the television through the external camera, the external camera of the television set collects the position information of the target user.
Step S202, obtaining the relative position information of the target user and the display screen according to the current position information of the target user and the position information of the display screen.
Further, step S202 further includes:
step S2021, establishing a coordinate system with the center position of the display screen, and obtaining a position deviation between the target user face position and the display screen with the target user face position as a reference point.
Specifically, in this embodiment, a spatial rectangular coordinate system is established with the center position of the display screen of the television, and the position deviation between the face position of the target user and the display screen of the television is calculated with the face position of the target user as a reference point. Further, the position deviation between the target user and the display screen of the television can be further determined according to the facial feature information of the target user, for example, the relative position information between the target user and the spatial rectangular coordinate system is obtained by calculation according to the position information of the pupils of the user in the spatial rectangular coordinate system, so that the position deviation between the target user and the center position of the display screen of the television is obtained by calculation. Specifically, when the horizontal line of the binocular pupils of the target user is detected to be lower than the middle horizontal line of the display screen, controlling the television base adjusting mechanism to move the display screen downwards until the horizontal line of the television display screen is obtained to be coincident with the horizontal line of the pupils of the target user; otherwise, when the horizontal line of the binocular pupils of the target user is detected to be higher than the middle horizontal line of the display screen, the television base adjusting mechanism is controlled to move the display screen upwards until the horizontal line of the television display screen is obtained to be coincident with the horizontal line of the pupils of the target user.
In a third embodiment, a method for adjusting a viewing angle of a display screen includes: collecting current position information of the target user; obtaining the relative position information of the target user and the display screen according to the current position information of the target user and the position information of the display screen; and establishing a coordinate system by using the center position of the display screen, and obtaining the position deviation between the target user face position and the display screen by using the target user face position as a reference point. In the embodiment, a spatial rectangular coordinate system is established through the center position of the display screen so as to calculate the position deviation between the target user and the display screen. Therefore, the efficiency of adjusting the visual angle of the display screen and the accuracy of adjusting are improved, and the target user obtains the optimal watching effect.

Specifically, in the present embodiment, the television terminal captures and determines a target user through an external camera, and determines a relative positional relationship between the target user and the display screen. That is, when the target user is at the left side of the display screen, the television system sends a control instruction to the motor MCU according to the collected position information of the target user, so that the driving motor performs the rotation of the television base and the adjustment of the curvature of the display screen according to the content of the control instruction, so that the adjustment of the viewing angle of the display screen is more intelligent, and because the target user stores the identity information in the television system in advance, the information includes the optimal viewing angle data of the user, in addition, the television system can adjust the display screen of the television according to the optimal viewing angle data pre-stored by the target user and the relative position relationship between the current user and the display screen, so that the viewing angle data of the adjusted display screen relative to the target user matches the optimal viewing angle data pre-stored by the target user.
And S302, adjusting the curvature of the display screen according to the distance between the target user and the display screen, wherein the curvature is large when the distance is short, and the curvature is small when the distance is long. Specifically, in this embodiment, that is, if the target user is located farther away from the display screen, in order to satisfy the viewing effect of the target user with a longer distance, the degree of curvature of the display screen needs to be larger, that is, the degree of curvature of the flexible display screen is not only related to the slope between the position information of the target user and the middle position of the display screen, but also related to the distance between the target user and the display screen.
In addition, in order to enhance the humanized design of a display device product, the linear distance between the target user and the display screen can be monitored, and when the linear distance between the target user and the display screen is smaller than the preset healthy distance, the user can be reminded to pay attention to the watching distance in a popping-up prompt box or sending an acousto-optic alarm lamp mode.
In this embodiment, according to the position deviation between the face of the target user and the display screen and the data information of the optimal viewing angle pre-stored in the system by the target user, the screen curvature and the current position of the display screen are adjusted on the current display screen, so as to achieve the purpose of quickly adjusting the relative position of the smart television and the user.
