Scanning type full-angles naked eye 3D display technology

Abstract

The invention discloses a scanning type full-angles naked eye 3D display technology. The display technology comprises the following steps: software performs real-time scanning and automatic slicing processing on an object 3D model, thereby obtaining a sectional view of the 3D model; a high-speed reciprocated digital optical projection system projects the sectional view to a high-speed diffuse reflection film to reproduce the shadow of the cross section, a three-dimensional object shadow is displayed by using the transient vision of the human eye through the shadow reproduction of the cross sections at different heights within short time. By combining the mechanical structure and the high-speed projection technology, the scanning type full-angles naked eye 3D display method is provided, theequipment is cheap, the ornamental experience is improved, and the technology has important significance and application scene for the 3D display.

Description

technical field [0001] The invention relates to the field of 3D display, in particular to a scanning full-angle naked-eye 3D display technology. Background technique [0002] It is common to use 3D display technology to create interlaced visual effects between virtual and reality. However, traditional 3D display methods require the viewer's line of sight to be staggered from the projector lens, receive polarized light at a specific angle, and have a negative impact on lighting, environment, and viewing angle. The control requirements are extremely strict, and the viewing is limited. It can only produce pseudo 3D of visual deception through perspective, occlusion, parallax, and aggregation. Moreover, the current 3D display technologies such as VR and HoloLens have problems such as harsh operating environment, expensive equipment, not imaging in space, and single viewing angle. In addition, because the human eye usually focuses on the two-dimensional display screen, while the...

[0002] It is common to use 3D display technology to create interlaced visual effects between virtual and reality. However, traditional 3D display methods require the viewer's line of sight to be staggered from the projector lens, receive polarized light at a specific angle, and affect lighting, environment, and viewing angles. The control requirements are extremely strict, and the viewing is limited. It can only produce pseudo 3D with visual deception through perspective, occlusion, parallax, and aggregation.

Moreover, the current 3D display technologies such as VR and HoloLens have problems such as harsh operating environment, expensive equipment, not imaging in space, and single viewing angle.

In addition, because the human eye usually focuses on the two-dimensional display screen, while the three-dimensional picture is in front or behind the screen, this contradiction between convergence and focusing not only increases the burden on the human eye and brain, but also causes eye fatigue when watching for a long time and discomfort, and may even cause mental disorders, so the present invention proposes a scanning full-naked-eye 3D display technology
