Is the holographic image of this year's Spring Festival Gala on the stage or on TV?

At present, holographic projection is completely immature. There are still many technical problems that have not been overcome. Even naked-eye 3D live holographic projection is not so simple in terms of environment and air. Now this aspect is in the experimental stage. Can only be done with certain substances in the air.

The method of the Spring Festival Gala is to synthesize the 3D software of the computer and the real-time live images, and then synthesize the set electrical signals through the transmission of the camera.

It can be said that this kind of synthesis can only be seen on the electronic equipment at the output end of the electric signal, but not on the spot audience.

Another 3D technology is to use transparent projection film. This technology is very mature now. However, this kind of projection film has 3D projection effect at a certain angle, but it can't realize holographic projection. It can be said that this is a kind of pseudo-3D. Actors must rehearse the interactive 3D projection in advance, giving the audience a pseudo-3D, which will cause the visual illusion of the audience.

According to this, it can be understood that the stage of the Spring Festival Evening is completely unsuitable for transparent projection film. The audience's angle coverage is too wide and the angle is incorrect.

Then, the 3D projection of the Spring Festival Evening is the synthesis of the later TV pictures.
