Problems solved by technology

Existing 3D scene rendering methods usually use panoramic pictures instead of 3D models, which causes the picture to be stretched into 3D space, and the clarity will be greatly reduced, resulting in distortion of the application effect

Embodiment Construction

[0016] The preferred embodiment of the present invention will be described in detail below in conjunction with accompanying drawing:

[0017] like figure 1 Shown is based on the 3D scene presentation method of 720 degree panorama VR, it comprises the following steps:

[0018] (a) Take panoramic video shooting along the direction that needs to roam, and establish a digital virtual scene; in the direction of roaming, you can choose a regular line to shoot at a uniform speed, or choose an irregular line to shoot at a non-uniform speed according to your needs; specifically It can be: process the laser data and mileage data obtained by the shooting robot with the slam algorithm to obtain a grid map in .pgm format, and then manually set the moving route and moving parameters on the grid map;

[0019] (b) Set two virtual image acquisition cameras to work in a digital virtual scene (to form a stereo camera group), so that the captured images are output as panoramic images; the images...

Abstract

The invention relates to a 3D scene presentation method based on 720-degree panoramic VR. The method comprises the following steps: (a) performing panoramic video shooting along a direction in which roaming is required, and establishing a digital virtual scene; (b) setting two virtual image collection cameras in the digital virtual scene for working, wherein collected images are output as panoramic images; (c) constructing two mapping spheres by using a 3D engine, and setting a virtual image output camera at the center of each mapping sphere; (d) respectively mapping the panoramic images ontothe two mapping spheres, and outputting mapping video streams having parallax via the virtual image output camera; and (e) combining the two groups of mapping video streams, and then displaying the combined mapping video streams via a video display. In this way, the panorama and virtual reality experience effect can be improved.

Description

technical field [0001] The invention belongs to the field of virtual reality and relates to a 3D scene presentation method, in particular to a 3D scene presentation method based on 720-degree panoramic VR. Background technique [0002] A 720-degree panorama is an image whose viewing angle exceeds the normal viewing angle of a person; the panorama is actually just a plane image generated by mapping the surrounding scene with a certain geometric relationship, and can only become a 3D panorama through the correction processing of the panorama player. The 720-degree panorama fully displays all the scenery within the double 360-degree spherical range. In the example, you can press and hold the left mouse button and drag to view all directions of the scene; and most of the 3D panoramas are obtained by stitching together photos The image retains the authenticity of the scene to the greatest extent; in the effect of horizontal 360-degree and vertical 360-degree viewing, although the...
