Perspective angle transform - shape from angle

Abstract

This paper derives the perspective angle transform as a relation between the angle in the three-dimensional space and its perspective projection. The properties of the transform are discussed, together with its application to the scene interpretation. A problem is considered in which the gradient information should be recovered for three segments separated in the three-dimensional space. An algebraic solution is shown. The solution is determined using the concept of virtual intersection and the perspective angle transform, based on the perspective moving coordinate.
