Holographic projection technology is one of the hotspots in the field of display. Using holographic projection technology, the human eye can directly see the three-dimensional image in space, which is considered to be the best solution for naked-eye 3D display. This paper introduces the development history of holographic projection technology, elaborates the basic principle of holographic projection technology and its advantages and technical difficulties, and analyzes the characteristics of holographic projection of air projection, laser beam projection and 360-degree projection. It has broad application prospects in the fields of military, education, medical care, display, film and television. With the increasing exposure of holographic projection technology, the application of holographic projection technology to life is getting stronger and stronger. Everyone wants to use holographic projection technology at home, especially for those who love technology and fashion. Although the holographic projection technology has been relatively mature, the effect of production is more dazzling, but if you want to apply it to your home, the road ahead is still very long, and there are many technical difficulties that need to be broken. With the IMAX theater now in place, IMAX movies can cover most of the viewer's viewable area, and despite the shocking visual experience, there is still an unreal feeling. Therefore, if holographic projection technology wants to exceed IMAX, it must have 360-degree fidelity, and it can be intelligently sensed, that is, it can sense the distance between the viewer and itself, and adjust the distance and size of the image according to the distance of the viewer. The visual shift of the viewer is that the picture will also be offset. When multiple video sources are displayed at the same time, there must be perfect stitching between the pictures, and a high stitching technique is required. People's ability to distinguish sounds exceeds vision. Holographic projection technology is necessary to ensure that viewers have a real experience. Therefore, not only immersive audio but also different directions or sound fields are required, and the effects heard by the audience are different. When a person in a holographic projection touches an object, the viewer can also feel the object, which requires the invention of the sensor, so that the viewer feels really touched. The best way to ensure that the holographic platform works properly is to achieve CPU and GPU memory sharing. Although technology is developing very fast, it takes a long time to achieve millions of parallel processing at the same time. To use millions of computers to synchronize all images, videos and other content that guarantees the authenticity of the holographic platform, the problem is that we need millions or even more host-level computers, which means that we have to wait until the holographic platform is commercially available. When it is operational, the originals we use will not have such a large order of magnitude and energy consumption. It is conceivable that the development of the application of holographic projection technology is very difficult. From the resource, it is a big investment. If the holographic projection technology is realized, how many people are willing to spend such a large amount of money to purchase, whether it has market competition. What about force? Although the holographic projection platform suffers a lot, the development of it is still going on, and the holographic projection platform will eventually appear.
