For the conventional VR headset, because the distance between the display terminal placed on the VR headset and the head of the user is shorter in the embodiment, the moment caused by the display terminal is reduced, so that the traction tension on the head of the user is reduced, that is, the embodiment of the invention can effectively reduce the head weight burden of the VR headset user.
In this embodiment, the fixing manner between the preset terminal fixing portion and the display terminal is a detachable fixing manner, and the detachable fixing manner may be any detachable fixing manner as long as the display terminal can be detachably fixed to the preset terminal fixing portion, and the fixing manner is not specifically limited herein.
It is understood that the above-mentioned posture difference specifically includes a posture difference and a position difference, that is, a posture difference and a position difference between the above-mentioned preset terminal fixing part and the conventional terminal fixing part.
In a specific embodiment, an included angle between a plane where the preset terminal fixing portion is located and a plane where the top portion or the bottom portion of the apparatus main body is located is 0 °.

Step S13: and when the display picture of the display terminal placed on the preset terminal fixing part is acquired, performing corresponding image picture output operation on the display picture by using the converted image output matrix.
It can be seen that, in the embodiment of the present invention, the terminal fixing portion for fixing the display terminal is located at the top or the bottom of the device main body of the VR headset, and the terminal fixing portion of the conventional VR headset is located at the front of the device main body, compared to the conventional VR headset, because the distance between the display terminal placed on the VR headset of the embodiment of the present invention and the head of the user is shorter, the moment caused by the display terminal is reduced, so that the pulling force applied to the head of the user is reduced, that is, the weight burden on the head of the VR headset user is effectively reduced. Moreover, after the terminal fixing part is optimized, the conventional image output matrix is transformed according to the pose difference between the terminal fixing part of the VR headset and the terminal fixing part of the conventional VR headset, so that the visual experience effect of a user using the VR headset in the embodiment of the present invention is the same as the visual experience effect of the user using the conventional VR headset, and therefore, the embodiment of the present invention can reduce the head weight burden of the user using the VR headset, and can not conflict with the conventional VR visual experience effect of the user.

wherein, predetermine the terminal fixed part and be located VR head-mounted device's the equipment subject's top or bottom, traditional terminal fixed part is located the front portion of traditional VR head-mounted device's equipment subject.
In this embodiment, the first coordinate system and the second coordinate system created based on the preset coordinate system creation rule are both rectangular spatial coordinate systems, as shown in fig. 3. Specifically, the coordinate system creating rule may be that a plane where the terminal fixing portion is located is an X Y plane, that is, a plane where the display terminal mounted on the terminal fixing portion is located is an XY plane, and a direction perpendicular to the plane where the terminal fixing portion is located is a Z-axis direction, where fig. 4 shows a self coordinate system of the display terminal already placed on the terminal fixing portion, that is, the self coordinate system of the terminal fixing portion.
Step S22: determining a posture difference in the pose difference according to the difference of coordinate axes between the first coordinate system and the second coordinate system; transforming a rotation matrix in the traditional image output matrix according to the posture difference in the posture difference to obtain a rotation matrix in the transformed image output matrix;
that is, the present embodiment may specifically determine the difference between the two coordinate axes in the attitude according to the difference between the two coordinate axes, and perform corresponding rotation on one of the two coordinate axes according to the difference in the attitude, so as to obtain the other coordinate axis.

For example, assuming that the first coordinate system needs to be sequentially rotated 90 ° counterclockwise along the Z axis, rotated 90 ° counterclockwise along the Z axis again, and then rotated 90 ° counterclockwise along the X axis, so as to change into the second coordinate system, based on the posture difference, the corresponding three rotation matrix units shown as follows can be determined:
then, multiplying the three rotation matrix units to obtain a corresponding posture transformation parameter matrix as follows:
assuming that the conventional image output matrix is specifically shown in fig. 5, it should be noted that [ 0001 ] in the last row in fig. 5 is added to form a 4 × 4 square matrix, which facilitates subsequent calculation. In fig. 5, the rotation matrix in the conventional image output matrix M is as follows:
wherein the sum of the squares of the three elements in each row of the above rotation matrix is 1. In this embodiment, the above-mentioned attitude transformation parameter matrix is multiplied by the rotation matrix in the conventional image output matrix, so that the transformation of the rotation matrix in the conventional image output matrix can be realized. Namely:
step S23: determining a position difference in the pose difference according to a difference between a central area position on the preset terminal fixing part and a central area position on the traditional terminal fixing part; and transforming the position matrix in the traditional image output matrix according to the position difference in the pose difference to obtain the position matrix in the transformed image output matrix.
The step of transforming the position matrix in the conventional image output matrix according to the position difference in the pose difference may specifically include:
determining a corresponding position transformation parameter matrix according to the position difference in the pose difference; and correspondingly transforming the position matrix in the traditional image output matrix by using the position transformation parameter matrix.
For example, in fig. 6, point a represents the position of the central area on the predetermined terminal-securing part, point B represents the position of the central area on the conventional terminal-securing part, and from point a to point B, it is necessary to move 0.02 m along the negative direction of the Y axis first, and then move 0.02 m along the negative direction of the Z axis, and the difference between points a and B can be represented by (0, -0.02, -0.02). Assume that the position matrix in the conventional image output matrix is the position matrix shown in FIG. 5, i.e., [ x ]1,y1,z1]TThen, based on the difference (0, -0.02, -0.02) between the points A and B, the corresponding position transformation parameter matrix [0, -0.02, -0.02 ] can be determined]TThen using the position transformation parameter matrix [0, -0.02]TFor the above position matrix [ x1,y1,z1]TPerforming transformation to obtain the following transformed graphPosition matrix [ x ] in image output matrix2,y2,z2]T：
As can be seen from the above, after performing corresponding transformation processing on the conventional image output matrix shown in fig. 5 according to the pose difference between the preset terminal fixing part and the conventional terminal fixing part of the VR headset, the following transformed image output matrix will be obtained:
step S24: and when the display picture of the display terminal placed on the preset terminal fixing part is acquired, performing corresponding image picture output operation on the display picture by using the converted image output matrix.
