MOVING BODY POSITION TRACKING APPARATUS AND MEHTOD OF SENSOR NETWORK BASE USING A POSITION DETECTING SENSOR

摘要

PURPOSE: A moving body position tracking apparatus and method of sensor network base are provided to enhance the accuracy of position tracking while reducing calculation time by efficiently selecting a plurality of distance measured values even if a plurality of sensors exists in a space.;CONSTITUTION: A plurality of sensor nodes(101-108) senses a signal transmitted from a moving body and transfers distance information with the moving body. An effective position calculating unit(1121) classifies the plurality of sensor nodes into an individual group and calculates location information of the moving body based on location information of the plurality of sensor nodes corresponding to the individual group. The effective position calculating unit calculates effective position information in the location information of the moving body. A position tracking unit(1122) estimates an error of the effective position information and calculates a Karman estimating and conversing value based on the error. The position tracking unit calculates location information of the moving body based on the Karman estimating and conversing value.;COPYRIGHT KIPO 2012
