Assembly auxiliary equipment of 3D stereoscopic image projection playing system

Abstract

The present invention relates to a piece of assembly auxiliary equipment of 3D stereoscopic image projection playing system, comprising a hanger frame assembly, a polarized light projection device and a metal curtain. The hanger frame assembly has a main frame, wherein three layers of tray plates with adjustable front and back pitch angles are disposed on the main frame; the upper and middle layers of tray plates are respectively used for stacking and fixing two projectors up and down; horizontal slots and location screw holes for plug-in mounting and fixing a polariscope tray are disposed on the upper and lower layers of tray frames; the polarized light projection device comprises two polariscope trays combined with the upper and middle layers of tray plates in a plug-in mounting manner; a polariscope clamping slot is disposed at a front end of the polariscope tray; the metal curtain is a hard substrate or a flexible soft base cloth standing front of the hanger frame assembly; silver inks, sliver powders, reflecting powders, light stabilizers and the like are coated on the surface of the substrate or the base cloth to obtain a metal reflecting coating. The product has the advantages of simple structure, convenient splicing and mounting, good focusing effect of polariscope, good texture display performance of the curtain and the like.

Description

technical field [0001] The invention belongs to the technical field of image projection and playback equipment, and relates to an auxiliary equipment for assembly of a projection playback system for dual projectors to realize projection and playback of 3D stereoscopic images. Background technique [0002] Currently, there are two types of equipment for realizing 3D stereoscopic dual-projector playback. It is a kind of equipment that is temporarily scattered and freely assembled. It has many disadvantages such as messy assembly structure, easy damage to the machine, and polarized lens or polarized film is easy to be burned through at close range. The other is the packaged structure equipment that has been professionally assembled and designed, including the hanger package (generally referred to as the hanger), polarized light projection device and metal screen, etc. There is currently no unified industry standard for this equipment, and the hanger package part exists The str...

AI Technical Summary

Problems solved by technology

It is a kind of equipment that is temporarily scattered and freely assembled. It has many shortcomings such as messy structure, easy damage to the machine, and polarized lenses or polarized films that are easy to focus and burn through at close range.

The other is the packaged structure equipment that has been professionally assembled and designed, including the hanger package (generally referred to as the hanger), polarized light projection device and metal screen, etc. There is currently no unified industry standard for this equipment, and the hanger package part exists The structure is complex, the implementation steps are cumbersome, the splicing and installation are inconvenient, the projection angle of the projector is not easy to adjust and fix, etc.; the polarized light projection device correspondingly has polarized lenses or polarized films that cannot focus well and cannot achieve the best results, and even polarized lenses Or the problem that the polarizing film may be burned through; the defects of the metal screen are: the professional reflective metal screen is expensive and the cost of construction is high, while the metal screen with general substitutes can not achieve the best effect, and it is easy to damage
