Embodiment 1

[0060] In Embodiment 1, the monocular rendering resolution is the same as the screen resolution. For the video image processing method based on virtual reality technology provided in Embodiment 1, see figure 2 As shown, including steps 201-207:

[0061] Step 201: Determine the screen resolution and monocular rendering resolution in the virtual scene.

[0062] Step 202: Determine the scaling ratio according to the screen resolution and the monocular rendering resolution.

[0063] Step 203: Send the zoom ratio to the two-dimensional image processor, and notify the size to be zoomed.

[0064] Step 204: the decoder decodes the video, and acquires video frames of the decoded video data.

[0065] Step 205: call the two-dimensional image processor to perform scaling processing on the video frame.

[0066] Step 206: Send the scaled video frame to the 3D image processor, and synthesize the scaled video frame and the corresponding virtual scene.

[0067] Wherein, the scaled video f...

Abstract

The invention discloses a video image processing method and apparatus based on a virtual reality technology. The method comprises the following steps: determining curtain resolution and ocellus rendering resolution in a virtual scene, wherein the curtain resolution in the virtual scene is consistent with video resolution in ocellus display in terms of size; according to the curtain resolution and the ocellus rendering resolution, determining a zooming proportion; obtaining video frames of video data after decoding, and according to the zooming proportion, performing zooming processing on the video frames; and sending the zoomed video frames to a three-dimensional image processor, and according to the zoomed video frames and the virtual scene, performing texture mapping. According to the method, by use of a professional two-dimensional image engine preset in a chip of a chip factory, after decoding, the video frames are zoomed first and then are sent to the three-dimensional image processor as texture display, and thus the purpose of saving three-dimensional image processing resources is realized.

Description

technical field [0001] The present invention relates to the field of virtual reality technology, in particular to a video image processing method and device based on virtual reality technology. Background technique [0002] Virtual reality technology (VR) is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. , immersing the user in that environment. The principle of stereoscopic imaging is to make the content seen by the left and right eyes different, so that the two eyes have parallax, and a three-dimensional illusion will be formed in the human brain due to parallax. Specifically, the left-eye image and the right-eye image are respectively provided by the 3D device. What the user's left eye sees is the image corresponding to the left eye, and what the right eye sees is the image corresponding to the right eye. Stereoscopic image. Virtual reality technology has experienced from being unknow...
