METHOD FOR ASYNCHRONOUS REPROJECTION OF 3D-SCENE IMAGE Russian patent published in 2023 - IPC G06T19/20 G06V10/24 

Abstract RU 2792721 C2

FIELD: image processing.

SUBSTANCE: group of inventions relates to processing of 3D-scene images, in particular, to a method for asynchronous reprojection in a virtual reality system. The claimed method for image processing consists of following stages: data on chromaticity and depth of an initial 3D-scene image for an angle A is received; based on data on chromaticity, visual signs of the image and their weight values are determined, based on data on depth, their depth is determined; a low-polygon grid is formed; the image is reprojected for an angle B different from the angle A by displacement of nodes of the low-polygonal grid, depending on weight values and depth of visual signs of the image. The claimed method for provision of a frame rate of an image consists of following stages: a frame of an initial image is received from an image generation device; the initial image is processed; a frame of the reprojected 3D-scene image is shown to an observer before reception of the following frame of the 3D-scene image from the image generation device.

EFFECT: claimed group of inventions allows for provision of a high frame rate of 3D scenes with lack of performance of 3D-rendering system, reduction in image distortions appearing near borders of objects in reprojection, and reduction in a data volume of 3D-scene image, transmitted via a communication channel.
