this paper. Geometry and Color Correction Techniques Hereld et al. have developed a technique for quickly and accurately assessing and correcting the alignment and distortion of the tiled array using a commodity digital camera [1]. In our approach we take a few pictures of test patterns covering of the entire display. Automatic analysis of these extracts a detailed geometrical mapping to subpixel accuracy of projector pixels to the display surface coordinates. We use the mapping to remove the distortions from the image by applying a piecewise bilinear warp
