Abstract

We explore the consequences of using only lines as our object in computer vision. We show a new constraint, which we call the prismatic line constraint. This constraint is based on the reconstruction of local shape using line measurements and rotation only, which is a new reconstruction in computer vision. We show that the point trilinear constraint can be broken down into the epipolar constraint and constraints on lines, which are thus the only constraints which need to be considered in computer vision.
