Problems solved by technology
[0007] The existing single-sided projection systems all adopt the method of ceiling installation of the projector, which needs to be installed with fixed connectors to the floor, which will have a force impact on the floor, and the installation is quite difficult, and it will also affect the appearance of the overall environment after installation
[0008] In addition, due to the problem of the installation position, the projector cannot be adjusted before and after the height, resulting in picture errors or blurred pictures
[0009] Professional projection equipment is expensive and fragile equipment, and it is easy to be dusty when placed on the ceiling for a long time
The virtual reality system equipment is all active high-power equipment, which has relatively high requirements for power supply. Due to the special installation location, it is difficult to install the power supply line, and there are great potential safety hazards
[0010] The existing technology also has certain defects in the installation method of the projection screen. At present, the installation of the screen is exposed, and the rear projection environment behind the projection screen is easily affected by the ambient light, which seriously affects the image quality.

Description
technical field [0001] The invention relates to a projection imaging device, in particular to a projection device with a box structure and a multi-box projection system for 3D stereo imaging technology, industrial simulation, and immersive virtual reality environment to realize virtual reality. Background technique [0002] Virtual reality technology was born in the 1950s, and the basic concept of virtual reality was gradually formed in the 1980s. At present, virtual reality technology has been gradually developed and perfected, and virtual reality laboratories and virtual reality environments have gradually increased and are widely used. In the fields of scientific research, education and high-end industry. Virtual reality systems mainly include virtual reality generators, sound synthesizers, sound localizers, head-eye-hand tracking devices, touch-sensing systems, and helmet-mounted displays. [0003] Existing virtual reality labs are all stacked, with a variety of hardwar...
