In general, when given a set of images and sufficiently many point correspondences, it’s possible to reconstruct the 3D object uniquely from these images. There are, however, some cases where such a reconstruction is not unique, these are called critical configurations.  We will show that all critical configurations consist of cameras and points lying on ruled quadric surfaces, and give a classification of all critical configurations for two cameras. We will also show how the different possible reconstructions are related.  This work is largely based on previous work by Richard Hartley and Fredrik Kahl.
