System, method and device for screen projection

Abstract

The embodiment of the invention discloses a system, a method and a device for screen projection. The system comprises a display screen and at least two groups of projectors, wherein the display screen is of a fully-sealed or partially-sealed casing structure; the inner wall of the casing structure is used for providing continuous images with viewing angles of 180 to 360 degrees in the horizontal direction; each group of projectors comprises at least one projector; the two groups of projectors are distributed in the center axis direction of the display screen by layers; each group of projectors is respectively projected onto one part of the inner wall of the display screen, the light paths of the two groups of projectors are kept away from audiences and seats, and the center axis is an axis which passes through a center point of the display screen, so that the display screen is arranged in a left and right symmetric way about the axis; each group of projectors is used for projecting transversely divided auxiliary display images of the to-be-displayed image according to the different projecting areas, and the auxiliary display images are spliced to form the complete to-be-displayed image. The system has the advantage that the projection light paths are not shielded by the audiences, so that the system can be applied to multiple types of screens.

Description

technical field [0001] The invention relates to the display field, in particular to a screen projection system, method and device. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] The development trend of human information communication technology is to continuously reduce the value of information entropy, and finally make the value of information entropy close to zero, that is, to reproduce the real world as realistically as possible. Since the appearance of movies, display devices have been constantly changing, improving and updating. [0004] Traditional screens are mostly single-plane screens, but in practical applications, the size of the plane screen is limited and cannot provide the audience with a feeling of no border. The border between the picture displayed on...

Problems solved by technology

[0008] However, when the orthogonal projection method is adopted, in order to ensure that the light path of the projector is not blocked by the audience, the audience seats need to be installed behind the projection light path of the projector, but when the shape of the screen is not a regular spherical shape, the audience seats should be installed At the back of the projection light path, it is impossible to guarantee that the audience can obtain a full-angle display image
