Problems solved by technology

[0010] In technology (2), the CAVE system based on LCD 3D splicing screen or large-size LCD screen does not require excessive ambient light and has higher color saturation than the rear projection wall, but long-term use will cause Inconsistent brightness and color attenuation between units, and cannot be restored
In addition, there are physical seams between the LCD screens, which affect the viewing effect
Large-size LCD screens are still difficult to transport

Embodiment Construction

[0037]

[0038] 3D glasses mainly achieve 3D effects by increasing the fast refresh rate of the picture (usually up to 120Hz), which belongs to active 3D technology, also known as time-sharing shading technology or liquid crystal time-sharing technology. When the 3D signal is input to the display device (such as a monitor, projector, etc.), the image is generated alternately in the frame sequence format to achieve left and right frames, and these frame signals are transmitted through infrared transmitters, bluetooth and other wireless methods, responsible for receiving 3D The glasses are refreshed synchronously to realize the corresponding images viewed by the left and right eyes, and maintain the same frame number as the 2D video. The two eyes of the audience see different images that switch rapidly, and create an illusion in the brain (the camera cannot shoot the effect), You can watch stereoscopic images.

Abstract

The invention discloses a CAVE screen display system and method adopting an LED 3D screen. The method comprises the following steps: collecting a coordinate position of an infrared marking point on a 3D glasses; estimating positions of double eyes of a user by using the coordinate position; performing calculation to obtain two groups of images displayed relative to the 3D glasses; alternatively displaying the two groups of images on the LED 3D screen; and switching left and right lens switches of the 3D glasses, wherein the switching frequency is matched with the switching frequency of alternative display of the two groups of images. By adoption of technical scheme disclosed by the invention, being different from the existing CAVE system, a virtual display space is suitable for environments with relatively strong light, the CAVE screen display system and method can be actually applied to bright indoor environments and even outdoor environments; the color saturation of the virtual display space is high, the display screens are seamlessly spliced to bring a very good viewing effect; and the service life is long.

Description

technical field [0001] The invention relates to the technical field of data display, in particular to a CAVE display system and method using an LED 3D screen. Background technique [0002] The CAVE system can be applied to any virtual simulation application field that requires immersion. For example, virtual design and manufacturing, virtual demonstration, collaborative planning, etc., are widely used. In most existing CAVE systems, the walls of the virtual display space are usually composed of rear projection walls. In addition to rear projection, the display of the ground part can also be projected onto the ground by placing a projector above the display space. With the development of technology, the technology of replacing projection display by LCD 3D splicing screen or large-size LCD 3D screen has also appeared. But still missing the way to use the LED 3D screen as a display for the CAVE system. [0003] There are two common CAVE systems in the prior art. [0004] (...
