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

[0035]

[0036] Such as figure 1 , the virtual display space of the present invention is composed of four small-pitch display screens, and the small-pitch display screens have the following characteristics: self-illumination, not limited by ambient light; high color saturation of the display screen, seamless splicing between display screens, and long service life . A plurality of infrared cameras are placed in the space corners of the small-pitch display screen; the number of cameras can be from at least 3 to more, depending on specific requirements, preferably, the number of cameras is eight. There are several infrared markers attached to the empty frame glasses. In addition, four independent 3D-channel rendering servers, multi-channel control servers, motion capture computers, infrared tracking systems, and network switches are required. The multi-channel control server is used to receive the position information of the user's eyes, and generate picture control signals f...

Abstract

The invention discloses a CAVE system display method adopting small-spacing LED screens. The method includes the following steps that an infrared tracing system collects the coordinate positions of infrared mark points on glasses; the positions of the eyes of a user are estimated according to the coordinate positions; the positions of the eyes of the user are sent to a multi-channel control server; the multi-channel control server conducts calculation according to the positions to obtain picture control signals of four channel rendering servers and sends the picture control signals to the four channel rendering servers respectively so that calibrated pictures can be displayed on the small-spacing LED screens. By means of the technical scheme, the small-spacing LED screens emit light themselves, making the method not limited by ambient light; the displayed pictures are high in color saturation, and the display screens are seamlessly spliced, have a long service life and are easy to transport due to the detachability. If the method is applied to a CAVE system, the limitations of various types of terminal display in the existing CAVE system can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of data display, in particular to a CAVE display system and method using small-pitch LED screens. 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. [0003] There are two common CAVE systems in the prior art. [0004] (1) CAVE system based on rear projection wall [0005] The virtual display spac...
