Abstract

A new method named Landmark-based Qualitative Reference System (LBQRS) is introduced to express qualitative positional information in this paper. LBQRS provides a dynamical positional framework. Under LBQRS, Qualitative Coordinates (QC) is defined based on cardinal directional relations between target objects and one or several landmarks adjacent to it. Formal model of LBQRS based on cognitive view of landmark position are presented. Formal description and representation method are provided.
