The embodiment of the invention provides an image generation method and an image generation apparatus applied to realistic near-to-eye display, the method comprises the following steps: converting a space imaging information of a to-be-displayed three-dimensional object to an eyepiece coordinate system from a world coordinate system to remove effect of an eyepiece on imaging; triggering a plurality of light rays at an exit pupil position, acquiring actual gray values of pixels respectively corresponding to the plurality of light rays in the converted imaging information, and thereby obtaininga first light field image reflecting a realistic image display effect of the three-dimensional object in human eyes; obtaining a second light field image through acquiring initial gray values of the pixels respectively corresponding to the plurality of light rays on a multi-layer display screen; correcting the gray values of the pixels in the second light field image according to the first light field image to obtain a third light field image. Thus, the third light field image is guaranteed to be more realistic than the first light field image reflecting the realism, and image display qualityis guaranteed.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an image generation method and device for realistic near-eye display. Background technique [0002] Compared with two-dimensional display, three-dimensional display can provide more intuitive visual experience and richer details, and is widely used in fields such as virtual reality and augmented reality. Recently, multilayer 3D displays have gained more and more attention in the field of 3D display. Generally speaking, a multilayer 3D display is formed by a plurality of parallel 2D display layers stacked along the thickness direction to produce a 3D visual effect. [0003] In some practical application scenarios, when people wear a 3D display such as a helmet-mounted 3D display, they often feel dizzy and uncomfortable. One of the main reasons for the discomfort is the image quality problem. Therefore, how to effectively generate more realistic and high-quality ...
