How to achieve 3D effect of large screen projection?
I have seen sci-fi blockbusters many times, and after taking 3D glasses in a good position, every moment is extremely instigating. The popopo sound surrounds the ear, overlooking the earth or looking up at the starry sky, or descending rapidly to the magnificent building, until you can't help yourself, reaching out to touch and feel the shock, then you can find your self.
However, for those who are engaged in the audio-visual field, while realizing a large screen, creating a 3D effect, or adding other viewing effects, etc., do a good job in each step of technology realization and sharing, and bring more shock to the public who like 3D viewing. Enjoy, is our ultimate Purpose.
First Troubleshoot the Problem
The realization of passive 3D technology is mainly related to polarizing plates, curtains and 3D glasses, so the troubleshooting is mainly from these aspects.
1. If the polarized is installed incorrectly or the polarized is damaged, there will be no 3D effect at the end or a bad 3D effect.
2. The 3D effects of the projector's superimposed screens are not completely overlapped.
3. The poor quality of the curtain, that is, the insufficient gain of the curtain will also cause the 3D effect to be poor. It is necessary to consult the professional in advance 4. Is the polarization of the 3D glasses filtered?
Pay attention to key points when doing passive 3D.
Pay attention to the gain of the curtain, it is recommended to control the gain value to about 2.1, which will not be dazzling, nor will it violate the visual comfort.
3D Polarized Placement
Generally, the placement of polarizing plates is divided into: positive and negative and sequential placement. Therefore, when doing passive 3D projectors
, whether it is using positive or negative placement or sequential placement, it is necessary to pay attention to the position of placement, avoiding reversal or disorder.
3D polarized and glasses should be unified
If the polarized is rounded, then the glasses must also be rounded, with the same line.
Pay attention to the selection of projection hanger
Due to the different on-site environments, the requirements for the overall environmental aesthetics, as well as the position and space of the projector, the smoothness of the operation, etc., are selected. The positioning is accurate, the distance and angle are adjusted, and no correction is needed for the next use.
