Embodiment Construction
[0018] 1. Evenly cover a layer of three-dimensional grating on the screen, and you can choose slit grating, lenticular grating or dot grating.
[0019] 2. There are two projection methods: front projection and rear projection. Front projection means that the projector is placed directly above or directly below the screen. Rear projection means that the projector is placed directly behind the screen. During rear projection, it is necessary to mount a layer of three-dimensional grating with the same parameters on the back of the screen again, so that the two sides of the screen are all mounted with three-dimensional gratings. Multiple projectors are arranged in-line or in a matrix.
[0020] 3. Adjust the projection position of the projector so that all display areas overlap completely.
[0021] 4. All the projectors play a group of multi-view stereo images at the same time.
[0022] 5. The viewer can see the stereoscopic image from the front.

The invention provides a multi-perspective naked eye three-dimensional projection technique and belongs to the field of naked eye three-dimensional projection. Three or more ordinary projectors are adopted, a group of multi-perspective three-dimensional series images are projected on a silver screen with the surface framed with three-dimensional grating, and through the shading property or refractivity of the three-dimensional grating, the left eye and the right eye of the human body can only see images played by one of the projectors respectively, so that the three-dimensional feeling is generated. The multi-perspective naked eye three-dimensional projection technique has the advantages that no special three-dimensional spectacles are needed to be worn, the visual angle is large, the three-dimensional feeling is high, the definition is high, the displayed breadth is large, and cost is low; when projection is conducted from the back side, the double surfaces of the silver screen cover the grating, and when projection is conducted from the front side, the single surface of the silver screen covers the grating; lenticular grating, slit grating and dot-lenticular can be selected for the three-dimensional grating.
Description
technical field [0001] The invention belongs to the field of naked-eye 3D projection. Background technique [0002] Traditional 3D image display technologies, such as 3D TV, some require special 3D glasses, some have a limited number of viewers, some do not have a strong three-dimensional effect, low definition, small format, and high cost. Can not give audience with good experience, thereby has limited the development of stereoscopic film and television. Contents of the invention [0003] The present invention adopts more than 3 ordinary projectors to superimpose and project a group of multi-view stereo series images onto a screen with a three-dimensional grating mounted on the surface, and through the shielding or refraction properties of the three-dimensional grating, the left and right eyes of a person can only You can see the images played by one of the projectors separately, thus creating a three-dimensional effect. [0004] It has the following advantages: [000...
