Image playing system for playing 3D movies by single projector

Abstract

The invention discloses an image playing system for playing 3D movies by a single projector, and relates to a movie playing system, in particular to a 3D movie playing system. The system comprises a 3D polarizer, a polarization lens, projection equipment, a data processor and polarized glasses; the data processor alternately transmits left and right screen images to the projection equipment in fixed frequency, and the projection equipment acquires two images which are continuously changed and crossed and are not overlapped; a servo unit in the 3D polarizer drives the polarization lens to rotate so that left and right switching frequencies of the polarization lens are synchronous with the switching frequency of the two images, the polarization lens rotating synchronously totally separates the left and right screen images by adopting the optical polarization technology, and the separated left and right images are continuously and alternately projected on the metal screen; and the polarized glasses are worn by spectators to watch the 3D effect image. The system has the advantages of no need of expressive films, wide film source, simple manufacture, low cost, convenient installation, simple operation, no need of debugging, convenient movement, no limitation of use places and the like.

Description

technical field [0001] The invention relates to a movie playing system, in particular to a 3D movie playing system. Background technique [0002] The traditional three-dimensional film adopts a three-dimensional film camera to take pictures, images are formed on two discs of film, and are projected synchronously by two projectors, so that the pictures of the two films on the screen are close without overlapping, and the projector lens does not add a polarizer. With the rapid development of digital technology and the digitalization of film, this traditional technology can no longer meet the existing requirements. [0003] Another way to achieve stereo is: two projectors are placed in a certain way, the position is fixed, and the two pictures are projected on the same screen point-to-point and synchronously. A piece of polarizer must be added in front of the lens of each projector, one is a horizontal polarizer and the other is a vertical polarizer. The audience must also wea...

AI Technical Summary

Problems solved by technology

The disadvantage of this projection technology is that it needs to use two or more projectors, and the position is fixed and cannot be moved. It needs to be adjusted by professionals on a regular basis, and the cost is high. It can only be used in large theaters, which limits the scope of use.
