Structure from motion of rigid and jointed objects

Abstract

A method for structure from motion is presented. The method makes a motion assumption about the objects being viewed. The motion assumption is that all motion consists of translations and rotations about a fixed axis. Parallel projection is also assumed. This makes it possible to interpret the motion of as few as two rigidly connected points. The method works for both rigid and jointed objects. Results of a test of this method on Johansson's data are presented. 1
