Ring screen projection is also called ring screen projection system, including ring screen system and ring screen projection. The ring screen projection system is divided into a three-dimensional ring screen projection system and a multi-channel three-dimensional ring screen projection system.
The ring screen (stereo) projection system is a highly immersive virtual simulation display environment. It uses a ring projection screen composed of multiple projections (channels). The ring screen radius usually ranges from 100 to 360 radians. Due to its large screen radius, the audience's vision is completely surrounded, and with the surround sound system, the participants can fully experience a highly immersive three-dimensional audio-visual experience and obtain a highly immersive virtual simulation visual environment. It is unmatched by traditional flat-screen display equipment. The most important application of ring-screen projection is stereoscopic projection system.
Stereo projection active and passive vertical rest. The passive stereoscopic projection system is enough to use two projectors, one projecting the image for the left eye and the other projecting the image for the right eye. The left and right eye images are projected onto the screen at the same time. A polarizer is installed in front of the projector lens to make the projected light into polarized light. The stereoscopic glasses worn by the audience are also polarizers, and the polarizer of the left eye is the same as the projection of the left eye. The polarization direction of the polarized light of the projector of the pavilion image is the same, and the polarization direction of the polarizer of the right eye is the same as that of the projector projecting the right eye image, so that the left eye image can only pass through the left eye lens, The right eye image can only pass through the right eye lens, So that the audience can see a three-dimensional image. The general projection method is to drive a projector by a graphics channel. In a multi-projector system, multi-projection channels are needed to support it. This is a multi-channel three-dimensional ring screen system.
Ring screen projection core technology
Due to the huge curvature and display characteristics of the display screen of the multi-channel ring screen projection system, its implementation technology is more complicated, and it needs a variety of core technologies as the overall support: such as digital geometric correction technology, multi-channel visual synchronization technology, edge fusion technology, Thereby forming a digital three-dimensional stereoscopic image with extremely high resolution without any distortion.
