Survey on screen calibration for multi-projector tiled display wall
多投影显示墙画面校正技术综述*

Multi-projector tiled display walls made of a set of projectors are the best choice for high performance and low cost large rendering system.In order to create perfect projection screen,it must make efforts to pre-compensate the output images' geometry distortion and color non-uniformity by the different characters of projectors. Based on their studies,the paper gave an overview of the research work done in the field of multi-projector tiled display wall,including existing problems,computation of geometry transform matrix,color model estimation and global color calibration.Finally,discussed existing problems,which need the further study and the further development of multi-projector tiled display wall.
