| 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. |
