Abstract

S. Ullman's classical (1979) results on motion/structure from orthographic views are revisited. Specifically, two results are presented: (1) two orthographic views allow an uncountably infinite number of solutions to motion/structure of a rigid body, and (2) a linear algorithm for solving motion/structure from four point correspondences over three views.
