Advances towards next-generation flexible multi-projector display walls

Multi-projector displays provide a large-scale and a high-resolution view at the same time. Today, projectors are commodity products, making such displays are affordable, but several challenges must be overcome in order to make this technology available to everyday users. We present several advances in the area of multiprojector displays. These employ projectors with enhanced capabilities, methodologies for efficiently and inexpensively calibrating and maintaining displays composed of these units, and the ability to handle imperfect and uncalibrated devices when performing geometric and photometric registration of imagery across multiple projectors. These are the first steps in realizing the goal of truly ubiquitous pixels, where users can be completely oblivious to the type and number of devices providing the display.
