Problems solved by technology

[0007] At present, the stand-alone 3D system uses one projector to realize 3D projection. Based on the principle of polarization, the polarizer will reflect a part of the light back. Since it does not have a light recovery system, this part of the reflected light is wasted, resulting in brightness ratio Low light recovery type 3D system and IMAX3D system

Abstract

The invention discloses a method and a device of image automatic calibration and optimization in a light recycling three-dimensional (3D) projection system. The method of the image automatic calibration and optimization in the light recycling 3D projection system comprises the following steps: (1) shielding a lower optical path, outputting an upper optical path, reducing a projection ratio automatically, enabling a collected image to be capable of filling a whole screen, adjusting a focal length, and adjusting the positions and heights of an X axis, a Y axis and an electronic support; (2) shielding the upper optical path, outputting the lower optical path, adjusting the collected image to magnify the image or reduce the image to enable the size of the optical paths to be identical. The device of the image automatic calibration and optimization in the light recycling 3D projection system comprises an image collecting and analyzing device, an image automatic calibration and optimization device and a projection device controlling and calibrating device. The method and the device of the image automatic calibration and optimization in the light recycling 3D projection system have the advantages of greatly reducing investing cost of a 3D movie projection system, reducing repairing and maintenance cost of devices in a later period, and effectively improving the adjusting accuracy of the 3D movie projection images.

Description

technical field [0001] The invention relates to an image automatic calibration and optimization method and device in a light recycling 3D projection system, belonging to the technical field of 3D projection. Background technique [0002] At present, the traditional IMAX3D movie projection system realizes high-brightness 3D projection by using two projectors, one of which plays the left-eye image, and the other one plays the right-eye image. Due to the use of two projectors, the brightness is doubled compared to a 3D system using one projector. [0003] However, due to the use of two projectors, there needs to be a certain distance between the two projectors, which will cause the size and position of the left and right images projected on the screen to be consistent, and the coincidence cannot be achieved. Therefore, it is necessary to perform image calibration on the left and right images so that the left and right images The images overlap exactly on the screen. [0004] ...
