The visibility concept is related to many application fields such as robot navigation, computer graphics and telecommunication systems. In this paper we propose a new qualitative model for visibility relations based on properties of the projective space.

Abstract

The visibility concept is related to many application fields such as robot navigation, computer graphics and telecommunication systems. In this paper we propose a new qualitative model for visibility relations based on properties of the projective space. Within the model we present a set of seven ternary relations among convex regions. Our model is capable to determine the visibility relation between a primary object A with the respect to a “region of view” C and an obstacle B. We developed the reasoning system, which allows the prediction of ternary relations between specific regions.
