Embodiment Construction

[0019] The method of the present invention provides a method for generating a three-dimensional panoramic space stereoscopic image for a panoramic stereo playback system, thereby improving the immersion and impact of the projection display system, and realizing a multi-dimensional display while ensuring a wider viewing angle and a higher resolution. User, multi-field of view experience.

[0020] The concrete workflow of the inventive method is as figure 1 Shown:

[0021] Step 1: Establish a 4π solid angle space, initialize a sphere 1 with 0 as the origin and R as the radius, where R is a positive number;

[0022] Step 2: Divide the sphere 1 into m parts by the latitude lines of the sphere, and divide it into n parts by the longitude lines of the sphere, wherein m and n are integers, and four adjacent longitude lines intersect with the adjacent two latitude lines to obtain four A plane quadrilateral is formed by these four intersection points, and a triangle is obtained at th...

Abstract

The invention relates to a generation method of a three-dimensional panoramic space stereo image, and belongs to the fields of computer image processing technology and electro-optic display technology. Aiming at the characteristics (an oversized field angle, namely the angle in the horizontal direction and the angle in vertical direction are both 360 degrees and far larger than a human eye field angle) of a panoramic (4 pi stereo angle space) display system and the problem of large-size stereo display, the generation method of the three-dimensional panoramic space stereo image based on stereo visual angle division is provided. An existing stereo image generation method is broken through, and through the building of the models such as longitude and latitude division, partial special angle range calculating and the like, the generation of a high-immersion panoramic stereo image is achieved. The generation of a large-visual-field high-resolution stereo image of a 4 pi space stereo angle is achieved, the needs that stereo observation is carried out simultaneously in multi-user and multi-angle modes in the fields including industrial design, virtual manufacturing, military simulation, astronomy and weather, studio entertainment and the like are met, and meanwhile, the generation method of the three-dimensional panoramic space stereo image can be popularized to the application of the generation of other large-visual-field-angle and high-immersion images.

Description

technical field [0001] The method of the invention relates to a method for generating a three-dimensional panoramic space stereoscopic image, and belongs to the fields of computer image processing technology and photoelectric display technology. Background technique [0002] High-resolution, high-brightness panoramic display systems are more and more widely used in scientific computing visualization, virtual assembly, military training, simulated driving, cultural entertainment and other fields. In order to achieve more visual impact and immersive experience, stereoscopic display technology has also been gradually introduced into these fields, becoming a research hotspot at home and abroad in recent years. At present, the resolution of most display devices is usually only a few million pixels. A single device cannot meet the requirements of high definition and large field of view. It is necessary to use a large-screen display form of seamless splicing of multiple projectors ...
