Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth to illustrate, but are not to be construed to limit the scope of the invention.

However, when some users use the desktop virtual reality system, a feeling of vertigo may occur, and vertigo cannot be effectively prevented by means of increasing screen resolution, refreshing frequency and the like, based on which the present embodiment provides a method for preventing vertigo, the method comprising:
and S1, determining the position data of the left eye of the user according to the position data of the center point of the left lens of the 3D glasses and the preset offset, and determining the position data of the right eye of the user according to the position data of the center point of the right lens of the 3D glasses and the preset offset.
It should be noted that the preset offset is an offset between an eyeball and a lens, and when a user wears the 3D glasses, the lens of the glasses and the eyeball of the user are not completely overlapped, as shown in fig. 2, a certain distance exists between the eyeball and the lens, and this distance is an offset D. The position data of the left and right eyes of the user can be obtained by adding the offset to the position data of the central points of the left and right lenses respectively.
Since different users have different facial structures, the offset can be set according to actual requirements. For example, the offset may be d 0.025m, which is determined by the distance between the normal eyeglasses and the eyeball being 2-3 cm.
It should be understood that, in order to obtain the position data of the center points of the left and right lenses of the 3D glasses, mark points may be set on the 3D glasses in advance, and since the positions of the mark points are fixed on the 3D glasses, the positions of the mark points relative to the center points of the left and right lenses are also fixed, so that after the position data of the mark points are identified, the position data of the center points of the left and right lenses may be calculated according to the position data of the mark points.
For example, as shown in fig. 3 and 4, 3 mark points may be set on the frame of the left lens by taking the center point of the left lens as the center, and then the position of the center point of the left lens in three-dimensional space can be determined by these 3 mark points, and the right lens may also be set with mark points in the same way.
Specifically, the left camera picture and the right camera picture can be obtained by shooting the 3D glasses through the binocular infrared camera on the 3D display, as shown in fig. 5, assuming that the point P is a mark point on the 3D glasses, the coordinate of the point P in the camera space is (X, y, z), and first, the coordinates of the point P projected on the left camera picture and the right camera picture are obtained, respectively (X, y, z)left，Yleft) And (X)right，Yright) Since both cameras are head-up cameras, Yleft＝YrightAnd Y, obtaining the following relation according to the intrinsic parameter focal length f of the camera:
and B is the base line distance of the binocular infrared camera.
From this, the coordinates (x, y, z) of point P in camera space can be calculated:
according to the above formula, the coordinates of all mark points on the 3D glasses can be calculated, and then according to the coordinates of all mark points and the position relationship between the coordinates and the center points of the left and right lenses, the position coordinates of the center points of the left and right lenses, namely the position data of the center points of the left and right lenses, can be obtained.
It can be understood that the image of the glasses can be subjected to image recognition processing, and after the image is subjected to expansion, binarization, filtering and other processing, a contour map of the 3D glasses can be obtained, so that the position data of the center points of the left and right lenses can be determined by an image positioning method.
It can be understood that the 3D glasses can be additionally provided with the attitude sensor, the position data and the attitude data of the 3D glasses are obtained in real time, and the position data of the central points of the left lens and the right lens of the 3D glasses are obtained through calculation according to the position data and the attitude data.
And S2, obtaining the posture data of the left eye and the right eye of the user according to the position data of the left eye and the right eye of the user.
It should be noted that, because the left and right cameras in the virtual scene in the 3D display simulate the eyes of the user and their distances and positions are fixed, their attitude angles are consistent with the attitude angle of the head of the user, and the attitude matrices of the left and right eyes of the user can be obtained by transforming the position data of the left and right eyes of the user into the world space.
It should be understood that if the position data of the 3D glasses is acquired by recognizing the mark point, the posture data of the left and right eyes of the user can be obtained by combining the world space coordinate system of the 3D glasses.
It should be understood that if the position data of the 3D glasses is obtained through the posture sensor, after the position data of the left and right eyes of the user is obtained, the posture data of the left and right eyes of the user can be calculated according to the posture data of the 3D glasses.
And S3, assigning the posture data of the left eye and the right eye of the user to a left camera and a right camera in a virtual scene in the 3D display respectively, and updating the virtual scene in real time according to the eye position of the user.

Optionally, in some embodiments, the scale, length, shape, and pattern of virtual objects within the virtual scene are the same as real objects within the real scene.
It should be noted that part of human perception of objects in a virtual environment is from the accumulation of knowledge about real objects in reality, and the visual experience is affected by too large or too small a virtual object relative to a real object. Therefore, the size of the object in the virtual scene should be as large as possible and the unit should be the same as the real object in the case of creating the model, and the material and texture of the model should be as similar as possible to those of the real object in the case of creating the virtual model, and the appearance of bright straight lines in the scene should be avoided. This also serves to assist in anti-glare.
Optionally, in some embodiments, the virtual scene is located within a preset region of the 3D display centered on the zero disparity plane.
In the current 3D imaging technology, the convergence effect of both eyes is used to form an image at a spatial point, so that a virtual object jumps out of or sinks into a screen, thereby forming a sense of depth and space. When the virtual object goes out of the screen or enters the screen, convergence and focus adjustment are inconsistent, and eyes continuously balance and adjust and adapt to each other, so that visual fatigue symptoms such as blurred vision, dry eyes, dizziness, nausea, vomiting and the like can be caused after a certain time. The zero parallax plane is a plane with only the convergence and focus consistent, and the farther away from the plane, the greater the convergence and focus difference is, the more fatigue and dizziness are easily generated.
Therefore, the virtual scene is displayed in the preset area of the 3D display with the zero parallax plane as the center, the user can be effectively prevented from being dazzled, and the size of the preset area can be set according to actual requirements.
Preferably, the virtual scene is arranged in this embodiment in a relatively comfortable area of a cube 0.13 meters in front and 0.3 meters behind the zero disparity plane position with respect to the virtual display.
By displaying the virtual scene in the area, better display effect can be obtained, and simultaneously, eye fatigue and dizziness of the user can be reduced.
It is to be understood that some or all of the steps described in the embodiments above may alternatively be included in some embodiments.
