Shape from perspective trihedral angle constraint

This paper defines and investigates a fundamental problem of determining the position and orientation of a 3 0 object using $ingle perspective i m g e view. The technique is based on the interpretation of trihedral angle constraid informution. A new closed form solution io the problem is proposed. The method also provides a general analytic technique for dealing with a class of problem of shape from inverse perspective projection by using "Angle to Angle Correspondence Information ". Simulation experiments show that our method is enective and robust for real application. t This research ispariially supported by ONR NooO14-91-J1306.
