An Approach of Generating Landmark Chain for Pedestrian Navigation Applications

Landmarks are predominant spatial features and play an important role in pedestrian navigation.This paper proposes a novel approach,landmark Chain,to include landmark information in pedestrian navigation applications.This approach is able to generate image sequences of landmarks for route guidance based on oriented visibility graph.An algorithm used for oriented visibility graph construction and landmark Chain generation is described.Results show that the proposed approach is able to provide guidance information by using image sequences with limited number of landmark images.
