Projector, immersive projection system and method

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...

AI Technical Summary

Problems solved by technology

However, in the application of the above-mentioned CAVE immersive system, multiple projectors with different focal lengths are often required to complete splicing and fusion, and the differences in the design of different types of projectors will cause a large deviation between the arrival time of the signal edge of the synchronization pulse signal and the ideal time , so the 3D glasses receive different synchronization pulse signals at the same time, which makes the synchronization timing of the light valves of the left and right eyes confused and makes it impossible to realize the 3D display effect
