DEVICE AND METHOD FOR PURCHASING LOCATION

摘要

A device and a method for chasing location are provided to chase the position of the target object in real-time by combining an inertia measuring instrument with a wireless sensor network, and to perform the position prediction by the Kalman filter. A wireless sensor network predicts the present position of a moving body through the wireless communication. An inertia measuring instrument predicts the moving trace corresponding to the movement of the moving body. A position calculating instrument generates the state propagation movement equation by using the output signal outputted from the inertia measuring instrument and offers the present position information predicted from the communication instrument based on wireless sensor network to the state propagation movement equation, so that the correction is performed and the position change is chased. The position calculating instrument comprises a position observation part(53) for finding position information from the signal generated by the wireless sensor network. A state propagation movement equation acquisition part(51) calculates the movement equation by processing the signal from the inertia measuring instrument. A movement equation correction and propagation part(52) offers the present position information to the state propagation movement equation and corrects and propagates.
