Problems solved by technology

When the short-wave light emitted by the projector is close to the wavelength of ultraviolet light, defined as 10-400nm (nanometer), the ultraviolet light will diffusely reflect on the human body, causing harm to the human body.
[0003] Most of the base color of the traditional projection screen is white, and the 3D image reflected to the human eye is formed by integrating the misplaced projected image with the help of 3D glasses to form a three-dimensional effect. Not only is it inconvenient to wear glasses, but the imaging definition is low, and the color of the signal itself cannot be obtained The restoration, contrast and image depth of field are not enough, and cannot meet the standards of advertising media and other practical industries

Abstract

The invention relates to a method for directly experiencing a three-dimensional visual effect through a transparent ultraviolet-proof projection screen. The method includes the following steps that A, the transparent ultraviolet-proof projection screen is prepared; B, a to-be-projected image with the bottom color being purely black is prepared and put in a projector to be played, the area of the to-be-projected image is smaller than or equal to 50% of the projected image area, and a user can directly experience the three-dimensional visual effect with naked eyes. Compared with the prior art, the method is easier, more convenient and rapider to operate and implement and lower in invested cost, due to transparency of the projection screen and rayleigh scattering imaging of nano-particles, visual effects with different field depths can be generated when the user sees the projected image on the transparent ultraviolet-proof projection screen, the bottom color of the projected image is faded to be transparent, the projected image has a special stereoscopic sense, the 2.5D or 3D image effect is displayed, and the three-dimensional visual effect can be directly experienced on the transparent ultraviolet-proof projection screen with the naked eyes without the help of 3D glasses.

Description

technical field [0001] The invention relates to the field of three-dimensional images, in particular to a method for directly experiencing three-dimensional visual effects. Background technique [0002] Currently, overhead projectors and slide projectors are widely used as a way for speakers to display materials at conferences and the like, and among them, video projectors and movie projectors using liquid crystals are also widely used in ordinary homes. The projection method of these projectors involves modulating light output from a light source with a projection type liquid crystal surface or the like to form image light, and emitting the image light through an optical system such as a lens to be projected onto a screen. When the short-wave light emitted by the projector is close to the wavelength of ultraviolet light, defined as 10-400nm (nanometer), the ultraviolet light will diffusely reflect on the human body, thereby causing harm to the human body. [0003] Most of ...
