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

Embodiment Construction

[0050] At present, a new type of display screen has appeared, and the new type of display screen is a fully enclosed or partially enclosed shell structure, and the interior of the shell structure is used to provide a viewing angle of 180 degrees to 360 degrees in the horizontal direction. consecutive images. The shell structure includes a cylindrical portion, and the side wall of the cylindrical portion is arranged in a smooth arc or in a straight line in an axial section. The shell structure further includes one or two end portions, and the one or two end portions are connected to the cylindrical portion in a smooth transition manner. For example, see image 3 , in this figure, the cylindrical part of the display screen is a cylinder, the side wall of the cylinder is arranged in a straight line in the axial section, and both ends are hemispherical structures. The viewer is located in the cylindrical part, facing the direction of the hemisphere to watch the display picture. ...

Abstract

The embodiment of the present invention discloses a screen projection system, method and device. The system includes a display screen. The display screen is a fully enclosed or partially enclosed shell structure. The inner wall of the shell structure is used to provide Continuous images with a viewing angle of 180 degrees to 360 degrees, the system also includes: at least two groups of projectors, each group of projectors includes at least one projector; the at least two groups of projectors are arranged in layers in the direction of the central axis of the display screen Each group of projectors is projected on a part of the inner wall of the display screen, and the optical paths of the at least two groups of projectors are kept away from the audience and the seats. The central axis passes through the center point of the display screen and makes it Axis of symmetry; each group of projectors projects horizontally divided sub-display images of the image to be displayed according to different projection areas, and the sub-display images are stitched together to form a complete image to be displayed. The projection light path of the present invention is not blocked by the audience and can be applied to various 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...
