Problems solved by technology

This type of equipment generally has the problem of inconvenient operation. The operator needs to be very close to the display system to operate, and the screen is blocked during the operation.
In addition, stray light interference is caused between the surface of the ball screen and the display device

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the embodiments of the accompanying drawings.

[0033] In order to solve the limitation that the digital projector is exposed outside the spherical screen in the rear projection form of the existing spherical display system, and the space constraints for the arrangement of functional auxiliary facilities are limited, and to solve the problem that the center angle of the effective area of ​​the spherical screen in the front projection form of the spherical display system is relatively small Due to small limitations, a spherical display system based on a fisheye lens with a large field of view is designed. It can be configured as a single-channel orthographic projection; this system uses a fisheye lens with a large field of view. On a continuous image field, the image field has the same shape as the spherical curtain, and the image field can effectively cover the range of the center angle β of the s...

Abstract

The invention discloses a spherical display system based on a super-wide field angle fish-eye lens. The spherical display system comprises a hardware subsystem and a software subsystem, wherein the hardware subsystem is provided with a built-in server or a computer host, a digital projection machine provided with the super-wide field angle fish-eye lens, a spherical curtain and other functional auxiliary facilities; the software subsystem comprises a system control unit and a specific audio and video file unit; the system control unit is used for control through wired or wireless communication; the specific audio and video file unit comprises audio and video source files meeting requirements; the projection manner is a single-passage rear projection or single-passage orthographic projection manner; and the super-wide field angle fish-eye lens is used for mapping a virtual object scene onto a large spherical center spherical curtain or an approximately spherical curtain bearing continuous image fields, so that the picture stereoscopic impression and space sense are higher, and the facilities such as the projection machine can be hidden inside the spherical curtain.

Description

technical field [0001] The invention relates to a spherical screen projection display system, in particular to a spherical display system based on a fisheye lens with a super large field of view. A projection display system capable of projecting images onto a spherical screen with a range of central angles. Background technique [0002] In the field of digital projection, it has long been attempted to provide a digital image display system that can make the picture cover the entire spherical screen or spherical screen (hereinafter referred to as "screen"), or, further, the shape of the spherical screen It can be extended to more generalized shapes characterized by three-dimensional convex shapes in space with axes of symmetry. For example, ellipsoid, paraboloid, quadric, etc. Such a display system would have many different uses. For example, the back projection form can be used in planetary science, and the display system can be used to display information such as planeta...
