The invention relates to a 3D scene vision spatial resolution enhancing method and system. The method comprises: rendering a specific 3D scene, and obtaining different visual angle metagraphs of the 3D scene, wherein the different visual angle metagraphs form a light field plane; obtaining the rendering information of the high frequency part of the projection light of the light field plane, and obtaining the rendering frames of high resolution; decomposing the rendering frames of high resolution into the subsequence frames of low resolution; and displaying the subsequence frames of low resolution in a high refresh rate. The method and system decompose the rendering frames of high resolution of the 3D scene into the subsequence frames of low resolution, display the subsequence frames of low resolution in a high refresh rate, utilize eye integral characteristics to fuse the subsequence frames, and enhance 3D scene vision spatial resolution and provide realistic simulating 3D effects under the condition of not increasing hardware cost.
Description
technical field [0001] The present invention relates to the technical field of 3D display, in particular to a method and system for enhancing visual spatial resolution of a three-dimensional scene. Background technique [0002] The objects seen by the human eye in nature are all 3D representations, but currently widely used displays can only provide flat images and cannot provide a real visual experience. With the continuous development of 3D vision technology, stereoscopic display is increasingly becoming the key to the development of future display technology. The human eye can perceive three-dimensional space from the retinal image of the two-dimensional space plane to generate depth intuition, which relies on the hint of depth cues. Currently commonly used 3D scene display methods include stereoscopic imaging technology based on binocular parallax, holographic imaging technology, and integrated imaging technology. [0003] The technical implementation and hardware requ...
