Today, in the field of projection display, holographic projection is undoubtedly the hottest topic. After years of continuous research and development, the application of holographic projection technology can now allow people to see three-dimensional images in space with the naked eye, without the need for 3D glasses. This is Naked-eye 3D projection A major advance.
With the increasing application of holographic projection, its magical and shocking visual experience has made many people fall in love with it, hoping that it can be widely applied to all aspects of life. However, if we want to popularize and apply holographic projection to every corner of life, there are still many technical difficulties to overcome.
1. 360-degree visual coverage area
Take the current IMAX theaters as an example. IMAX movies can cover most of the audience's visual area. Although they provide a shocking visual experience, there is still a sense of unreality. Therefore, if holographic projection technology wants to surpass IMAX, it must have 360-degree fidelity and intelligent sensing, that is, it can automatically sense the distance between the audience and itself, and adjust the distance and size of the image according to the distance of the audience. When the audience's vision shifts, the image will also shift. When multiple video sources are displayed simultaneously, the images must be perfectly spliced, requiring high splicing technology.
2. The audience requires a realistic scene atmosphere and a true feeling of the object
When 3D holographic projection When a person in the projection touches an object, the audience also needs to feel the object. This requires the invention of sensors to make the audience feel like they are really touching it.
3. How to ensure realistic sound effects
People's ability to distinguish sounds exceeds their vision, 3D holographic projection If the technology wants to give the audience a realistic experience, it must ensure the authenticity of the sound. Therefore, not only immersive audio should be adopted, but also the effect heard by the audience should be different in different directions or sound fields.
4. Efficient memory allocation and super image processing capabilities
To ensure the normal and stable operation of the holographic platform, the best method is to achieve CPU and GPU memory sharing. Although technology is developing rapidly, it will still take a long time to achieve millions of parallel processing simultaneously.
