Fig. 7From: Learning-based active 3D measurement technique using light field created by video projectorsSamples of eigenvectors visualized in image format (eigenimages) for grid patterns. The top row images are eigenimages for a grid pattern to use one projector, the middle row images are for grid patterns by two projectors, and the bottom row images are for grid patterns by three projectors. From left columns to right, the 2nd, 3rd, 11th, and 12th eigenimages in the order of eigenvaluesBack to article page
