CN105652582A - Multi-perspective naked eye three-dimensional projection technique - Google Patents

Abstract

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

Various visual angles bore hole stereo projection technology

Technical field

The invention belongs to bore hole 3d projection field.

Background technology

Conventional stereo image display technology, such as stereoscopic television etc., what have needs wearing Special stereoscopic glasses, and some viewing numbers are restricted, and some third dimensions are strong, and definition is not high, and breadth is little, and cost is high. Spectators can not be given with good experience, thus limiting the development of three-dimensional film.

Summary of the invention

The present invention adopts the general projectors of more than 3, one group of various visual angles stereoscopic series image overlap is projected to surface and mounts in the screen of 3 D grating, by the blocking property of 3 D grating or refrangibility, the left eye and the right eye that make people can only be respectively seen the image that wherein a certain projector is play, thus producing third dimension.

It has the advantage that

1. need not wear special anaglyph spectacles.

2. many people can watch, visible angle width, be suitable for large-scale movie theatre.

3. third dimension is strong, because its employing is physics compound display method, it does not have pixel limits.

4. definition is high, because have employed multiple projector, and each broadcasting is high definition image.

5. breadth is big, and the viewing area with conventional projector is the same, and area is up to tens square metres.

6. cost is low, because it uses common projector and conventional 3 D grating.

Accompanying drawing explanation

Fig. 2 uses the structural representation of individual grating when being from front projection. Multiple stage projector is put in the surface of beholder or underface.

Detailed description of the invention

1. one layer of 3 D grating of uniform fold in screen, optional narrow gap grating, column mirror grating or round dot grating.

2. projection pattern has front projection and rear projection two kinds, and front projection refers to that projector is placed on the positive front upper place of screen or positive front lower place, and rear projection refers to that projector is placed on the dead astern of screen. During rear projection, it is necessary to again mount last layer at the back side of screen and there is the 3 D grating of identical parameters, so just all mount 3 D grating on the two sides of screen. Multiple stage projector is inline or matrix arrangement.

3. adjust the projected position of projector, make all of viewing area all completely overlapped together.

4. all projectors play one group of various visual angles stereoscopic series image simultaneously.

5. beholder is from front it is seen that stereoscopic image.

Claims (1)

1. various visual angles bore hole stereo projection technology, it is characterized in that: adopt the projector of more than 3, various visual angles stereoscopic series image projecting is mounted in the screen of 3 D grating to surface, projection pattern comprises front projection and rear projection, 3 D grating as above, it is primarily characterized in that: light can selectively be blocked or reflects, containing chequered with black and white transparent film grating, the column mirror grating of lens refractive Iy and round dot grating.
