The initial position of the terminal equipment is also determined based on the distance and the direction between the first camera/the second camera and the target characteristic point. The target feature point in this step refers to an object in a real environment, such as a pen, a table, and the like. Wherein the initial position of the virtual screen refers to: and when the virtual screen is launched for the first time, the position of the virtual screen is located. The initial position of the terminal device is as follows: the location of the terminal device when the virtual screen is first launched. Specifically, when determining the positions of the two, the feature points may be used as an origin to establish a rectangular coordinate system, so as to determine the position coordinates of the two respectively.
Step S102, determining the current position of the terminal equipment;
in this step, the current position of the terminal device is also determined based on the current distance and the current direction between the first camera/the second camera and the target feature point. The current position of the terminal device refers to the position of the terminal device after the virtual screen is launched for a period of time. Specifically, a rectangular coordinate system may be established with the feature point as an origin, so as to determine the position coordinates of the terminal device.
Step S103, acquiring a position deviation value based on the initial position of the terminal equipment and the current position of the terminal equipment;
in this step, the variation of the two positions can be calculated by the initial position of the terminal device and the current position of the terminal device after movement determined in the above two steps, that is, the position deviation value is calculated and obtained by the initial position coordinate and the current position coordinate of the terminal device.
Step S104, determining a target position of the virtual screen according to the position deviation value and the initial position of the virtual screen, so as to adjust the position of the virtual screen to the target position.

In this step, the terminal device is an AR glasses, as shown in fig. 3, the first camera a and the second camera B are symmetrically disposed on the glasses on both sides of the perpendicular bisector along the horizontal direction with the perpendicular bisector of the glasses as a symmetry axis (i.e., disposed on both sides of the left and right eyes of the AR glasses), and the first camera and the second camera may specifically be fisheye cameras. The two fisheye cameras A and B respectively have own visual space ranges (such as sector areas in FIG. 3), then spatial feature point detection is carried out in the respective visual space ranges, a common spatial feature point is found out after the two fisheye cameras A and B are overlapped to be used as a target feature point C, then the distance between a central point and a spatial feature point between the two fisheyes is found out by combining an IMU (inertial measurement unit) and an algorithm, a virtual screen is placed on a connecting line between the central point D1 of the two fisheyes and the target feature point C, the initial position of the virtual screen is determined, and F in FIG. 3 is the initial position of the placed virtual screen.

After the target feature point C is determined, the position information of the first camera A or the second camera B relative to the target feature point C can be determined by taking the target feature point C as a reference object. Specifically, a plane coordinate system can be established by using the origin of the target feature point, so as to determine the position coordinates of the first camera or the second camera, and thus determine the initial position of the terminal device.
Step S203, determining a second relative position of the first camera or the second camera relative to the target feature point when the terminal equipment is located at the current position; and determining the current relative position of the central point between the first camera and the second camera relative to the target characteristic point according to the second relative position and the first distance so as to obtain the current position of the terminal equipment.

Step S204, acquiring a position deviation value based on the initial position of the terminal equipment and the current position of the terminal equipment;
in this step, after the initial position coordinates D1 and the current position coordinates D1' of the terminal device are determined, the position deviation value of the terminal device can be calculated.

In this embodiment, after the virtual screen is dropped at the target position F ', the distance between the virtual screen and D1 ' may be adjusted according to actual conditions, that is, when there is an obstacle between the virtual screen F ' and D1 ', the distance between the virtual screen F ' and D1 ' may be reduced, that is, the virtual screen is dropped at a position close to D1 ' along the direction of the connection line between F ' and D1 '.
In a specific implementation process of the embodiment, the virtual screen position can be adjusted according to an adjustment signal by receiving the adjustment signal for adjusting the virtual screen position; for example, the operation of adjusting the position of the virtual screen is started by manually triggering the repositioning interactive mode, and specifically, the operation can be completed by triggering a button arranged on the terminal device, triggering a mouse, a keyboard hot key, and the like.
Of course, the present invention may also detect the usage time of the virtual screen, compare the usage time with a preset time, and adjust the position of the virtual screen when the usage time reaches the preset time. Namely, the position of the virtual screen is automatically adjusted after the virtual screen is thrown to the preset time by detecting the throwing time of the virtual screen. Or whether the terminal moves is detected in real time, and the position of the virtual screen is automatically readjusted after the terminal moves, so that the position of the virtual screen is timely adjusted, and the user experience is improved.

The virtual screen is used for displaying the screen on the virtual screen, so that people can be personally on the scene, the user can neglect the surrounding situation and cannot notice the surrounding obstacle information, and danger is easy to occur.
In the embodiment of the invention, whether the orientation of the terminal device (AR glasses) rotates or not can be detected, when the orientation of the terminal device (AR glasses) rotates, the rotation angle of the current position of the terminal device relative to the initial position is determined, and the rotation angle of the virtual screen is determined according to the rotation angle, so that the throwing position of the virtual screen is determined, and the position is adjusted.
