The invention is embodied in a block adjustment method and apparatus which simultaneously aligns a set of overlapping images in order to construct an image mosaic. For each one of the images of the set, the invention performs the alignment by determining ray directions relative to a 3-dimensional coordinate system at plural predetermined pixel locations in the one image. For each one of the plural pixel locations in the one image, ray directions are determined relative to the 3-dimensional coordinate system of the corresponding pixel location in each one of the other images overlapping the one predetermined pixel location of the one image. Then, incremental deformations of the overlapping images are computed which simultaneously minimize differences between the ray directions of plural pairs of the overlapping images which include the one image. The foregoing is performed for each of the plural predetermined pixel locations of the one image simultaneously. The images are warped in accordance with the incremental deformations and the process is repeated.
