3D display device and method linking elliptical ground screen with elliptical ring screen

Abstract

The invention relates to a 3D display device and method linking an elliptical ground screen with an elliptical ring screen. The device comprises a virtual simulation unit used for establishing a virtual digital model according to an actual environment, the virtual digital model comprises a 360-degre elliptical ring screen and the elliptical ground screen, the 360-degre elliptical ring screen and the elliptical ground screen are vertically arranged, and a virtual object is arranged at the center of the elliptical ground screen; a primary rendering unit used for obtaining a rendering resolution according to an actual projection resolution and primarily rendering the virtual digital model; a camera setting unit used for establishing two visual cameras and a top end camera in the virtual digital model, the visual field of the visual camera covers a part of the elliptical ground screen and the 360-degre elliptical ring screen, and the top end camera is located above the scene of the virtual digital model; and a final rendering unit used for completing final rendering according to the sequence rendered by the top end camera. Compared with the prior art, the 3D display device and method provided by the invention have the advantages of having better audio-visual effect and being simple and intuitionistic, etc.

Description

technical field [0001] The present invention relates to a 3D projection technology, in particular to a 3D display device and method in which an elliptical ground curtain and an elliptical ring curtain are linked. Background technique [0002] In the current exhibition industry, commonly used sand table display methods include physical sand table and digital projection sand table. The traditional sand table shows its static and monotonous functional limitations in the display: first, due to space constraints, the performance of local details is limited; second, the characteristics of its objects are not easy to update and load new information; third, the function is single , the amount of information expressed is limited, and commentators and other supporting support are often required. The audience can't get an immersive look and feel. This way of information expression shows more and more limited shortcomings in the rapidly developing information age. [0003] In recent ...

Problems solved by technology

[0007] The existing patent application 2014100479834 discloses a 3D projection display method of an L-shaped vertical screen, but this display method can only show the performance carrier seen in front of the eyes, and the best viewing area is only in the center, so both the display effect and the viewing effect exist. insufficient
