Motion and Structure from Orthographic Projections

T. S. Huang, C. H. Lee

Research output: Contribution to journalArticlepeer-review


Ullman's classical results on motion/structure from orthographic views are revisited. Specifically, we present two results: 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.
