Immersive three-dimensional rendering projection system and method for moving view point on curved screen

Abstract

The invention relates to an immersive three-dimensional rendering projection system and method for a moving view point on a curved screen. The method is based on an immersive three-dimensional rendering projection system for a moving view point on a curved screen. The method comprises the following steps: acquiring user information: tracking user's head position and posture information, and estimating user's binocular positions and sight direction; setting three-dimensional rendering parameters: according to the estimated user's binocular positions and sight direction, adjusting a three-dimensional camera in real time to perform three-dimensional rendering of the moving view point on the parameters; performing dynamic parallax adjustment: performing post processing on the parallax of the rendered three-dimensional image according to the relative position relation between the user and the screen and the geometric shape information of the projection screen, so that the user views comfortable and correct three-dimensional images at his position; optimizing user perception: for user's head posture and eyeball movement, further optimizing the image respectively after the dynamic parallax adjustment; and projecting a three-dimensional scene: watching a virtual roaming three-dimensional scene by the user wearing a pair of three-dimensional glasses.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic projection, and in particular relates to an immersive stereoscopic rendering projection system and a method thereof for moving a viewpoint on a curved screen. Background technique [0002] With the advent of the information age in the 21st century and the maturity of digital technology, the rapid development of virtual reality technology and augmented reality technology, the cultural entertainment industry has undergone tremendous changes in the past 20 years of continuous exploration. The contents, methods, means and carriers of entertainment are all integrated with new ideas and high technology. As a result, participatory entertainment facilities that integrate many of the latest technologies continue to emerge in places such as exhibition halls, expo halls, and science and technology museums in many cities in our country. As the basis of virtual reality technology and augmented reality te...

Problems solved by technology

[0008] In order to solve the above problems, the present invention overcomes the fact that the stereoscopic projection system in the prior art cannot render the scene image in real time from the perspective of the user's observation, and cannot allow the user to observe the virtual image of the scene/object from different angles by moving, so that the scene/object really exists in the physical environment. The illusion of the world, the problem of poor user experience and sense of existence, provides an immersive stereoscopic rendering projection system and method for moving the viewpoint on a curved screen, by tracking the position of the user's eyes, and
