Two-wing holographic projection sand table device and projection method for 3D line model roaming

Abstract

The invention relates to a two-wing holographic projection sand table device for roaming three-dimensional line models. The first side and the second side are both rectangular surfaces, using high light-transmitting materials, and the bottom surface of the horizontal triangular prism is a rectangular surface. The lens of the first projector faces the first side of the horizontal triangular prism and can project toward the first Image projection is carried out on the side, the lens of the second projector faces the second side of the horizontal triangular prism and can carry out image projection to the second side, the first projector and the second projector project to the first side and the second side of the horizontal triangular prism The projection pictures on the two sides are synchronous pictures in space. The invention can form a holographic projection roaming effect on engineering lines.

Description

technical field [0001] The invention relates to the technical field of holographic projection, in particular to a two-wing holographic projection sand table device and a projection method for roaming a three-dimensional line model. Background technique [0002] Holographic projection technology is a technology that uses the principles of interference and diffraction to record and reproduce three-dimensional images of objects. The current holographic projection device mainly surrounds the cone transmission device with multiple or four sides. Based on the holographic synthesis effect formed by the refraction of light in the center of the cone, the audience can see from different sides of the cone as if from different angles. Project different sides of the model. Limited by the expression of the cone bounding box, the device can usually only perform holographic projection on a single model with a small volume, such as a person, a car or a building. Once the projected volume ex...

AI Technical Summary

Problems solved by technology

Limited by the expression of the cone bounding box, the device is usually only capable of holographic projection of a single model with a small volume such as a character, car or building. Once the projection volume exceeds the size of the projection device, such as a railway in a large scene Highway engineering, the projection effect will be seriously distorted

[0003] In addition, the model scene is limited by the size of the projection space, so that the scene can only be expressed in a static closed space, and the roaming expression effect required for linear engineering simulation cannot be achieved
