Problems solved by technology

[0005] 1) A single image is directly split through the screen splitter, and it cannot be based on the actual physiological parallax of the viewer (due to wearing equipment, due to interpupillary distance, etc.), stably and truly restoring the difference between the binocular images;
[0006] 2) The image captured by a single camera is ultimately from one observer origin, while the images of two observer origins obtained by dual cameras will introduce parallax ghosting due to the target object, and the elimination of ghosting depends on external equipment;
[0007] 3) The synchronization between the two images after binocular acquisition is directly related to whether the user is dizzy, and the difference in color, saturation and exposure of the two images will also reduce the perception of virtual reality;
[0008] 4) The content of the traditional binocular view is fixed parallax and cannot be changed

Embodiment 1

[0069] Embodiment 1 (virtual reality immersive entertainment)

[0070] In virtual reality immersive entertainment such as roller coasters, deep sea tours and games, if the acquisition device is a single camera or synthesized and spliced ​​into a single image data source, the present invention can perform virtual active parallax compensation rendering on the virtual device side to give users Provides the best immersive entertainment experience with low ghosting and high image quality.

Embodiment 2

[0071] Embodiment 2 (360-degree panoramic live broadcast)

[0072] When performing 360-degree panorama acquisition and live broadcast of sports events or concerts, multi-channel image arrays usually perform image fusion in real time, thus losing the unique perspective of multi-cameras. Through the present invention, virtual active Parallax compensation rendering to provide users with the best panoramic live broadcast experience with low vertigo and ghosting and high image quality.

Abstract

The present invention provides a binocular rendering method and system for virtual active parallax computation compensation. The method comprises: active parallax computation: performing binocular rendering adaptation on an initial user to obtain a dedicated adaptive parallax synchronization matrix corresponding to the user; image parallax compensation and cropping: using the dedicated adaptive parallax synchronization matrix of the user as a cropping factor for virtual active parallax compensation, cropping a complete image into left and right eye groups; and binocular rendering: pre-rendering dichoptic images of the same monocular camera on a waiting overlay canvas of a next scene, and rendering and projecting, according to a fixed time sequence period, a composite image of the prepared overlay canvas on a target display hardware layer in one pass. In the present invention, a single camera is used as basic image acquisition hardware, and ghosting causing dizziness is reduced since, after software-based parallax computation compensation, the effect approaches one in which a wearer directly observes natural objects with their own eyes. Optimal adjustment of parallax is actively achieved, and a cropped single view source is reversely compensated, achieving a more immersive visual effect.

Description

technical field [0001] The present invention relates to the technical field of virtual reality image processing, in particular to a binocular rendering method and system for virtual active parallax calculation compensation. Background technique [0002] There is a certain distance between the two eyes of people, so when observing a three-dimensional object, because the two eyes are horizontally separated at two different positions, the observed object images are different, and there is an aberration between them, due to this The existence of aberration, through the human brain, can feel the stereoscopic effect. How to use the method of virtual active parallax to compensate rendering so as to enhance the perception of virtual reality is the key point of the present invention. [0003] The imaging foundation relied on in virtual reality is based on simulating two different images with aberrations seen by binoculars in the natural environment, while monocular camera acquisitio...
