Abstract

The invention discloses a 3D holographic imaging device, which comprises a first projection assembly, a second projection assembly, a third projection assembly and a fourth projection assembly, wherein the first projection assembly, the second projection assembly, the third projection assembly and the fourth projection assembly are telescopically connected in sequence. When the projection surfaceof the first projection assembly, the projection surface of the second projection assembly, the projection surface of the third projection assembly and the projection surface of the fourth projectionassembly are unfolded, the first projection assembly, the second projection assembly, the third projection assembly and the fourth projection assembly form a tetrahedron which is communicated up and down. The 3D holographic image scene is convenient to assemble and store, and the portability is high.

Description

technical field [0001] The invention relates to the technical field of 3D images, in particular to a 3D holographic image device. Background technique [0002] In order to realize holographic images, a deep-field projection booth is usually composed of a curtain and multiple light sources. However, the existing deep-field projection environment usually requires a lot of manpower and material resources to build, and the projection booth is not easy to carry. Every time it is applied to a different scene, it needs to be rebuilt, which is inefficient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a 3D holographic image device to improve the portability of the projection booth. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A 3D holographic image device, comprising a first projection assembly, a second projection as...
