Problems solved by technology

[0003] The image formed by the above-mentioned 3D projection system on the metal screen is formed by the splicing / superposition of three beams, so there are strict requirements on the imaging position of the three beams, otherwise, once there is a misalignment between the beams, the viewing effect will be seriously affected
However, at present, most of them use manual correction for alignment, and the alignment accuracy is limited.

Abstract

The invention is suitable for the stereo projection technical field and provides a high-luminous-efficiency 3D system capable of carrying out image automatic correction. The high-luminous-efficiency 3D system comprises a polarization light-splitting assembly, a first reflected light beam direction adjusting assembly, a second reflected light beam direction adjusting assembly, a transmitted light beam adjusting assembly, motors from No.1 to No.5, a CCD camera and a control module. According to the invention, the CCD camera collects images formed on a metal curtain by each light beam, the control module automatically analyzes the deviation of each light beam, and then the corresponding motors are driven for adjustment, so that the images formed by all the light beams are totally superposed.

Description

Technical field [0001] The invention belongs to the technical field of stereo projection, and particularly relates to a high-light-efficiency 3D system capable of automatic image correction. Background technique [0002] At present, 3D projectors mostly use stereo projection technology with low throw ratio and high luminous efficiency. The principle is to divide the incident beam into three parts by using a polarization splitting component, namely two reflected beams and one transmitted beam, and then three beams are placed on a metal screen. The light is superimposed together. With this design, about 70% of the projector’s light can be converted into polarized light, thereby improving the light utilization rate of the stereo projection device and increasing the brightness of the projection screen. At the same time, it has the characteristics of small structure and low projection ratio. Suitable for projectors with a ratio of 1:1. [0003] The image formed by the above 3D projecti...
