Abstract :
In his work on motion analysis, Ullman (1979) showed that for the orthographic case, four-point correspondences over three views are sufficient to determine motion and structure of the four-point rigid configuration. However, his method is nonlinear and the conditions of uniqueness and convergence of his algorithm are not made clear. A simple linear algorithm to solve Ullman´s problem of determining motion and structure from three orthographic views is presented. Necessary and sufficient conditions of a unique solution are also given
