The embodiment of the invention also does not limit the response speed of the chip or the server on the display for acquiring the actual position parameters, and each acquisition can be a real-time continuous response, a millisecond-level response or a microsecond-level response.
In another embodiment of the present invention, the acquiring the actual position parameter between the display and the human face includes: receiving a face image monitored by a camera of the display; recognizing the face image to form face data; and analyzing the face data to obtain the first actual offset distance.
Specifically, a camera is calibrated in advance to determine a functional relationship f between the distance between any two image points in an image formed by the camera and the distance between two corresponding object points, the camera monitors the face image and then sends the face image to a chip or a server of a display, the chip or the server recognizes the face image by using an image recognition technology to obtain face data (such as coordinates of two eyes), coordinates of a center point of two eyes in the face image can be determined based on the face data, the distance X 'from the center point of two eyes in the face image to the first preset reference line L1 is further analyzed, and then the chip or the server can calculate the first actual offset distance X according to the functional relationship f and the distance X'.
In another embodiment of the present invention, the acquiring the actual position parameter between the display and the human face includes: receiving the second actual offset distance monitored by a distance sensor of the display.
It should be understood that the distance sensor is used to monitor the distance between the display and the center point of the eyes, and the embodiment of the present invention is not limited to a specific type of distance sensor, and may be an infrared distance sensor or an ultrasonic (sonar) distance sensor.
Specifically, when the user is located within a certain area in front of the display, the distance sensor on the display may monitor a second actual offset distance Z between the display and the center point of both eyes, and finally the distance sensor sends the second actual offset distance Z to the chip or the server.
In another embodiment of the present invention, the acquiring the actual position parameter between the display and the human face includes: receiving a face image monitored by a camera of the display; recognizing the face image to form face data; and analyzing the face data to obtain the third actual offset distance.
Specifically, based on the calibrated functional relationship F, after the camera monitors the face image and sends the face image to a chip or a server of a display, the chip or the server recognizes the face image by using an image recognition technology to obtain face data (such as coordinates of two eyes), determines coordinates of center points of two eyes in the face image according to the face data, further determines a distance Y 'between the center point F of the two eyes in the face image and a second preset reference line L2, and then the chip or the server calculates a third actual offset distance Y according to the functional relationship F and the distance Y'.
It should be understood that the third actual offset distance Y may be a change in the height of the head of the user, or a change in the angle between the head of the user and the horizontal plane at a certain height (i.e. looking up or looking down), in other words, when the angle between the head of the user and the horizontal plane is continuously changed, the distance between the center point of the human eye and the second preset reference line of the display is also continuously changed.

Specifically, based on the calibrated functional relationship f, firstly, after the camera monitors the face image and sends the face image to a chip or a server of a display, the chip or the server recognizes the face image by using an image recognition technology to obtain face data (such as coordinates of two eyes), determines coordinates of center points of two eyes in the face image according to the face data, further analyzes the coordinates to obtain a distance X 'from the center points of two eyes in the face image to the first preset reference line L1, and then the chip or the server calculates a first actual offset distance X according to the functional relationship f and the distance X'; secondly, a distance sensor on the display can monitor a second actual offset distance Z, and the distance sensor sends the second actual offset distance Z to the chip or the server; finally, the chip or the server calculates the actual offset angle theta by using the tangent function relation between the first actual offset distance X and the second actual offset distance Z.
It should be noted that the area range in which the user is located may not be infinite, the area range is determined according to the camera and the distance sensor of the display, and the user only needs to be located in the area range that can be monitored by the camera and the distance sensor.
In another embodiment of the present invention, the acquiring the target position parameter between the display and the face comprises: receiving an actual vision value input by a user; acquiring different preset visual force values and preset corresponding relations between different preset distances from the display to the face in the second direction; and determining the preset distance corresponding to the actual visual force value as a second target distance in the second direction according to the preset corresponding relation.
It should be understood that actual vision values refer to the user's own vision values that the user manually enters into the display; the preset vision value refers to a plurality of known vision values between 1.0 and 2.0 in increments, such as 1.0, 1.2, 1.4, 1.6, 1.8, and 2.0, and so on; the preset distance is a distance between the face and the display when the user can clearly view the display under the preset visual force value, and the preset corresponding relationship is a one-to-one corresponding relationship between the preset visual force value and the corresponding preset distance.
Specifically, the chip or the server receives an actual visual force value input by a user, reads a preset corresponding relationship between different preset visual force values and corresponding preset distances, which are stored in the memory in advance, and finally determines the preset distance corresponding to the actual visual force value according to the read preset corresponding relationship, and takes the preset distance corresponding to the actual visual force value as the second target distance in the second direction.

It should be understood that the specific value of the first target distance is not limited in the embodiments of the present invention, and the first target distance may be zero (i.e., the center point of the two eyes coincides with the first preset reference line) or may be close to zero (i.e., the center point of the two eyes is close to the first preset reference line).
In another embodiment of the present invention, the acquiring the target position parameter between the display and the face comprises: and acquiring a third target distance between a second preset reference line of the display and the face in a third direction perpendicular to the horizontal plane.
Specifically, the chip or the server reads a preset distance between a second preset reference line of the display and the face in a third direction perpendicular to the horizontal plane, which is stored in a memory in advance, and the preset distance is used as a third target distance.
It should be understood that the specific value of the third target distance is not limited in the embodiments of the present invention, and the third target distance may be zero (i.e., the center point of the two eyes coincides with the second preset reference line) or may be close to zero (i.e., the center point of the two eyes is close to the second preset reference line).

For adjusting the position of the display in the direction of S2, specifically: when the chip or the server obtains a second actual offset distance and a second target distance, the chip or the server firstly compares the second actual offset distance with the second target distance to determine whether the actual horizontal distance value needs to be adjusted (if the second actual offset distance is different from the second target distance, it indicates that the second actual offset distance needs to be adjusted), and when the second actual offset distance is different from the second target distance, the chip or the server adjusts the second actual offset distance to the second target distance to adjust the position of the display in the direction of S2, where the position of the display is the position where the user can clearly view the display.
For adjusting the position of the display in the direction of S1, specifically: when the chip or the server acquires a first actual offset distance and a first target distance, the chip or the server firstly compares the first actual offset distance with the first target distance to determine whether the first actual offset distance needs to be adjusted (if the first actual offset distance is different from the first target distance, it indicates that the first actual offset distance needs to be adjusted), and when the first actual offset distance is different from the first target distance, the chip or the server adjusts the first actual offset distance to the first target distance to adjust the position of the display in the direction of S1, where the position of the display is the position where the first preset reference line L1 coincides with the center point of the eyes of the user.
