Embodiment 1

[0040] Such as figure 1 As shown, this embodiment provides a 3D display method, including:

[0041] Step 101, acquire the user's left eye position coordinates and right eye position coordinates.

[0042] In this embodiment, the process of obtaining the left eye position coordinates and right eye position coordinates in step 101 may include: firstly acquiring the real-time image of the user; then performing image recognition on the real-time image to obtain the user's left eye position coordinates and right eye position coordinates . Wherein, the real-time image of the user can be obtained by a digital camera that includes an image sensor; in particular, in order to ensure the update rate of data, the output frame rate of the digital camera is above 60 frames per second, and the digital camera uses a wide-angle lens.

[0043] In this embodiment, in addition to the image processing methods described above, methods such as active target marker assistance can also be used to obt...

Embodiment 2

[0057] Such as figure 2 As shown, an embodiment of the present invention provides a 3D display device, including:

[0058] A human eye positioning unit 201, configured to acquire the user's left eye position coordinates and right eye position coordinates;

[0059] The parameter calculation unit 202 is connected to the human eye positioning unit, and is used to calculate the parameters of the two cameras in the virtual scene displayed in 3D according to the left eye position coordinates and the right eye position coordinates obtained by the human eye positioning unit;

[0060] The parameter adjustment unit 203 is connected to the parameter calculation unit, and is used to adjust the two cameras respectively according to the parameters calculated by the parameter calculation unit;

[0061] The graphics rendering unit 204 is connected to the parameter adjustment unit, and is used to render the viewports of the two cameras whose parameters have been adjusted by the parameter adj...

Abstract

The invention discloses a 3D display method and device, relates to the field of virtual reality, and aims at solving the problem of insufficient performance of trueness of a virtual scene in the prior art. The technical scheme disclosed by the embodiment comprises the steps that S10, the left eye position coordinates and the right eye position coordinates of a user are acquired; S20, the parameters of two cameras in a 3D display virtual scene are respectively calculated according to the left eye position coordinates and the right eye position coordinates; S30, the two cameras are respectively adjusted according to the parameters; S40, rendering is performed on the viewports of the two cameras of which the parameters are adjusted so that rendered images are obtained; and S50, the rendered images are transmitted to a 3D displayer which is connected in advance so that the 3D displayer is enabled to process the rendered images and then display the rendered images. The scheme can be applied to a virtual reality system.

Description

technical field [0001] The invention relates to the field of virtual reality, in particular to a 3D display method and device. Background technique [0002] Currently, commonly used 3D display technologies include non-flicker 3D display technology, shutter 3D display technology and naked-eye 3D display technology. In the prior art, the 3D display technology includes: outputting two sets of virtual scene images corresponding to the left and right eyes of the user to the eyes respectively, the left eye can only see the virtual scene images corresponding to the left eye, and the right eye can only see the virtual scene images corresponding to the right eye. 3D display of the virtual scene image. [0003] However, since the two sets of virtual scene images output to the left and right eyes are unchanged when the user is in different positions, the realism of the virtual scene is insufficient. Contents of the invention [0004] The invention provides a 3D display method and d...
