Abstract

Spatial information services in indoor space are an important application area of GIS as in outdoor space. In this paper, we propose a framework for tracking moving objects in indoor symbolic space with RFID sensors. First, we introduce the concepts of indoor symbolic space and tracking in indoor symbolic space, and define the accessibility graph for trackable indoor symbolic space. Second, we propose a deployment method of RFID readers and a construction algorithm of accessibility graph for trackable indoor symbolic space and a tracking method in indoor space with RFID sensors. Finally, we present an implementation example and the result of experiment with real data to validate the proposed method.
