Projection control method, device and system

Abstract

The present application provides a projection control method, device and system. In the scene where holographic projection needs to be realized, N independent imaging devices will be transported to the corresponding site and then spliced ​​and combined, so that the N imaging devices under the spliced ​​structure , the corresponding subspace projection imaging areas can form a holographic projection imaging area, and the relative position information between the N imaging devices under the current splicing structure can be determined according to the identification information on the N imaging devices, so as to combine N The projection relationship between the imaging device and the projection device is to control the projection device to project the three-dimensional image to be projected to the N imaging devices, and the sub-projection images under different viewing angles to ensure that the currently formed holographic projection imaging area can realize the projection to be projected 360-degree rendering of three-dimensional images. There is no need to carry a bulky box, and the equipment is conveniently transported, which greatly reduces the requirements for the holographic projection display site.

Description

technical field [0001] The present application mainly relates to the field of electronic technology, and more specifically relates to a projection control method, device and system. Background technique [0002] Holographic projection technology (front-projected holographic display) is a virtual imaging technology that uses the principle of interference to record and reproduce real three-dimensional images of objects, bringing people a new visual enjoyment. [0003] In practical applications, the reflection of the object to be projected is usually projected onto the surface of the inclined high-transparency film glass used for imaging, and the observer can see the three-dimensional image floating inside the glass through reflection, such as figure 1 Schematic diagram of the scene shown. It can be seen that in order to realize holographic projection in the prior art, a box with a volume equal to or greater than the cube of the imaging area is often required, which has a huge...

Problems solved by technology

It can be seen that in order to realize holographic projection in the existing technology, a box with a volume equal to or greater than the cube of the imaging area is often required. The structure is huge, which has great limitations on the holographic projection display site, and the transportation is also very inconvenient.
