Popis:	A projection is a mapping between linear spaces, which preserves collinearity, and whose restriction to any line is injective or constant. Motivated by applications in photogrammetry, we prove that any projection from a subset M of a (little) Desarguesian projective space to another such space is a product of a central projection and an isomorphism, provided M is not too small and the image of M is not contained in one line.
