ABSTRACT
Most existing calibration techniques for multi-projector display system require that the display configuration remain fixed during the display process. We in this paper present a new approach to continuously re-calibrate the projection system to automatically adapt to the display configuration changes, while the multi-projector system is being used without interruption. By rigidly attaching a camera to each projector, we argument the projector with sensing capability and use the camera to provide online close-loop control. In contrast to previous auto or continuous projector calibration solutions, our approach can be used on surfaces of arbitrary geometry and can handle both projector and display surface movement, yielding more flexible system configuration and better scalability. Experimental results show that our approach is both accurate and robust.

Calibrating multi-projector cylindrically curved displays for "wallpaper" projection
PROCAMS '08: Proceedings of the 5th ACM/IEEE International Workshop on Projector camera systemsThis paper presents a novel algorithm for calibrating multiple casually placed projectors, via a single uncalibrated camera, to produce a "wallpaper" projection, which is equivalent to printing a single image onto a flat sheet of paper and pasting it to ...
Easy Calibration of a Multi-projector Display System
In this paper, we present a method for the geometric calibration of a multi-projector display system. The method is such that in order to calibrate the system, the user is only required to place the projectors and capture a single image of the images ...
Scalable and view-independent calibration of multi-projector display for arbitrary uneven surfaces
AbstractMost existing systems for calibrating multi-projector display suffered from several important limitations such as dependence on point of view, restriction on the display surface and moreover the number of projectors and using obtrusive markers. In ...
