Embodiment Construction

[0025] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are given in conjunction with the embodiments.

[0026] See figure 1 , figure 1 It is a system schematic diagram of a 3D projector according to an embodiment of the present invention. The projector 10 of the present invention includes a data processing module 1 and an OSD module 2 . In practical applications, for example, in a DLP-based projector, the data processing module 1 can be integrated into a DLP chipset.

[0027] The data processing module 1 is used for detecting 3D video and audio data and converting it into a 3D format picture signal. The OSD module 2 includes a switch component 21 for controlling a synchronization signal in the 3D format picture signal, wherein the synchronization signal is used to trigger the 3D viewing device One of the left eye light valve and the right eye light valve is opened. In ...

Abstract

The invention provides a projector and an immersive projection system and method. The immersive projection system comprises a 3D viewing device, a first projector and a second projector, the first projector and the second projector are used for splicing projection, the first projector emits a first synchronization signal, the second projector closes a second synchronization signal, and the 3D viewing device receives the first synchronization signal of the first projector for 3D display synchronization. According to the projector, the function of a 3D synchronous signal switch is added in the OSD, and the projector has higher elasticity to select and guarantee normal use of the 3D function. According to the immersive projection system and method provided by the invention, the 3D synchronization signals of one part of projectors in the system are closed, and the 3D synchronization signals of the other part of projectors are shared, so that the problem that 3D watching equipment in an immersive system cannot be normally synchronized can be solved.

Description

technical field [0001] The present invention relates to projection display technology, in particular to a projector, immersive projection system and method which can be used in virtual reality applications. Background technique [0002] At present, immersive interactive projection refers to projecting the projection screen onto a large or multi-sided projection screen through multi-channel projection fusion technology, so that the audience feels like they are in the film. Immersive projection can fully cover the audience's perspective, and the audience is completely immersed in a high-level virtual simulation environment surrounded by stereoscopic projection pictures (for example, including five groups of left, middle, right, upper and lower pictures), obtaining an immersive experience. three-dimensional audio-visual images and interactive experience of the environment. The CAVE immersive system is a highly immersive virtual reality system, which organically combines high-r...
