Application fields of naked-eye 3D projection

　　Common 3D holographic imaging is divided into: 180°, 270°, and 360°. 180° is suitable for single-sided display, generally used in holographic projection on stages with a larger 3D imaging area, and can achieve interaction; 360° can project the image into the mid-air of a real scene, forming a sense of depth, allowing viewers to watch from any angle. The emergence of naked-eye 3D projection technology not only solves the problem that 3D projection technology must wear glasses to watch the display design, but also improves the shortcomings of holographic projection technology that cannot be fully omnidirectional without blind spots.

　　Currently, naked-eye 3D projection technology is widely used in various fields. In the military field, 3D holographic projection technology can simulate battlefield environments, thus providing support for analysis, decision-making, and actions, realistically and portably; in the education field, it can break through the limitations of time and space, using dynamic, temporal, and narrative virtual images to showcase history, truly achieving student participation and experience, and achieving the integration of education and entertainment; in the film and television field, 3D holographic imaging technology can give people a stronger sense of reality. In ultra-large screen cinemas, without wearing special glasses, the ultra-large stereoscopic picture combined with surround stereo sound effects can make the audience feel immersive; in stage effects, it allows the audience to directly see the three-dimensional virtual characters and objects on the stage, thus creating a visual atmosphere that is both illusory and real, with a super strong visual impact.
