A Way to Prevent Optical Interference of Multi-projector Display System

Abstract

Abstract:

In the 360° fully enclosed multi-projection display system, in order to reduce the interference between projections by light diffuse reflection from

projection screen, correction scheme based on digital image processing technology is used to preprocess the image of frame buffer. Correction scheme by proprocessing is enforced

by analysing the difference between pre-interference and pro-interference image, then the model relationship among the image of frame buffer, the image of pre-interference

projection and the image of pro-interference projection image is established. Proved by the experiment, the technology has good effect on solving the problem of image contrast

droped by light interference in totally closed multi-projection display system.

Key words: close, multi-projection, diffuse reflection, optical interference
