Embodiment Construction

[0018] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, it is a schematic diagram of an embodiment of the spherical display-based multi-projector overlay system of the present invention. A multi-projector overlay system based on a spherical display, including a ball screen 1, a computer 6, a first projector 4, and a second projector 5, the first projector 4 corresponds to the first fisheye lens 2, and the second projector 5 Corresponding to the second fisheye lens 3; an opening is arranged at the lower end of the ball screen 1, and the fisheye lens is arranged in the middle of the opening. The light emitted is projected onto the ball screen 1 through the fisheye lens 2, and the light emitted by the projector 5 is projected onto the ball screen 1 through the fisheye lens 3; the computer 6 is connected with the first projector 4 and the second projector 5 respectivel...

Abstract

The invention provides a system and a method for superimposing multiple projectors on the basis of stereoscopic display. Brightness is strengthened by a multi-projector superimposing mode, and pictures projected by each projector to a spherical screen are processed in advance, so that the pictures projected by the multiple projectors to the spherical screen are perfectly coincided, and purposes of strengthening the display brightness of the large spherical display and lowering cost are achieved. In addition, the system is simple in installation and debugging, and requirements on manufacture of displayed materials are low. The system comprises the spherical screen, a computer and two or more projectors; each projector is provided with a fish-eye lens; an opening is arranged at the lower end of the spherical screen; the fish-eye lenses are arranged in the center of the opening, and light emitted by the projectors are respectively projected to the spherical screen via the fish-eye lenses; and the computer is connected with each projector and used for controlling the pictures projected from the projector to the spherical screen, so that images projected from the projectors to the spherical screen are completely coincided.

Description

technical field [0001] The present invention relates to the technical field of projection display, in particular to a multi-projector overlay system and method based on spherical display. Background technique [0002] At present, due to the large surface area of ​​large spherical display products, the brightness of a single ordinary projector is not enough, and the price of high-brightness projectors is very expensive, and the procurement cost is too high. Therefore, a solution to achieve high-brightness projection by superimposing multiple projectors came into being to achieve higher brightness and clarity. The existing technology is usually achieved by splicing and merging multiple short-focus lens projectors. The screen to be displayed is divided into several parts, which are projected by several projectors respectively. The joint parts are simply spliced ​​or partially overlapped. The brightness of the overlapping part will be higher than other places, and the brightnes...
