How did Charlie and Teresa Teng sing together?

Holographic technology is an illusion, and illusion can sometimes produce a charm.

In this case, the commonly used holographic technology in business can be roughly divided into two categories: one is the rear projection method, in which the projector directly projects the image onto the holographic film.

The other is to reflect the projection or LED image onto the holographic film placed at 45 degrees by reflection.

The most important thing to choose which projection method is to consider the site environment.

How to do it:

Therefore, the virtual image of Teresa Teng in Jiangsu Satellite TV is realized by holographic projection technology, and the scene is invisible. Only the live TV broadcast is to superimpose the computer-generated image of Teresa Teng on the picture taken by the camera, and only the audience in front of the TV can see the duet of Charlie and Teresa Teng.

Holographic projection technology still needs scientific and technological iteration to develop, and it is believed that real holographic technology will appear in the near future.
