Method and system for double-camera registration adjustment for digital cinema projectors

Abstract

The invention discloses a method and system for double-machine overlap adjustment for digital movie projectors. The double-machine overlap adjustment system includes a screen, two digital movie projectors that have been installed, and a set of digital images for grabbing projected images on the screen. Acquisition system, a set of data analysis and processing system, a set of hardware processing system and a set of data transmission system, the method of realizing double-machine overlap adjustment is as follows: start the double-machine overlap adjustment system, automatically select and set the two digital cinema projectors One is the master, and the other is the slave; based on the test chart projected by the master, the lens parameters of the slave are automatically controlled, so that the test chart projected by the slave and the test chart corresponding to the master meet the coincidence requirements. It can conveniently perform fast and accurate coincidence adjustment on the projection screens of the dual projectors.

Description

technical field [0001] The invention relates to the automatic adjustment technology of digital cinema, in particular to a method and system for adjusting the coincidence of double projectors of digital cinema. Background technique [0002] Usually, due to the limitation of the maximum brightness that digital cinema projectors can provide, cinemas equipped with giant screens need to use two digital cinema projectors for joint projection to achieve standard projection effects. This requires that the pictures (images) projected by the two projectors on the screen can achieve high-precision positional coincidence and definition matching, so as to reduce the bad viewing experience brought by ghosting to the audience. However, in the process of use, with the increase of time, due to the drift of the projector support system, the vibration of the projector itself, the interference of the ventilation duct system, and accidental collision, the dual screen will be separated, so freque...

AI Technical Summary

Problems solved by technology

[0004] 1. For the dual-projector system, the image is blurred due to the separation of the dual-projector screens, and the 3D effect becomes poor, which affects the viewing experience;

[0005] 2. Frequent manual adjustments are required during daily screenings, which will interfere with the theater's film scheduling plan;

[0006] 3. System adjustment requires professional technicians, and general cinema projection personnel do not have the corresponding ability;

[0007] 4. System adjustment requires multi-person collaboration and repeated comparisons, which takes a long time
