PEDESTRAIN POSITION INFORMATION SYSTEM AT GPS NON-ACCEPTING REGION USING LOW-COST INERTIA SENSOR AND A METHOD OF ACQUIRING LOCATION INFORMATION

摘要

PURPOSE: A pedestrian position information system at GPS non-accepting region and a method of acquiring position information are provided to confirm its own position on map using presumed position information with laptop and display device and share multilateral position information using wireless telecommunication.;CONSTITUTION: A position data acquiring sensor part(110) comprises GPS(Global Positioning System)(111), and an acceleration sensor(112), a gyro sensor(113), a terrestrial magnetism sensor(114), and an altitude sensor(115). A position data acquiring sensor part acquires position information of pedestrian using sensors and outputs the acquired position information to position data estimating unit(120). A position information estimating operation unit comprises a posture estimator(121), a directional angle estimator(122), a height estimator(123), a walk detecting and step estimator(124) and a digital filter. A position data display part(130) indicates position information of pedestrian presumed from a position information estimating operation unit at the map. A position data communication part(140) shares position information of several pedestrians by wirelessly communicating position information presumed position information of pedestrian and a position information map displaying unit.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Position data acquiring sensor; (112) Acceleration sensor; (113) Gyro sensor; (114) Terrestrial magnetism sensor; (115) Altitude sensor; (120) Acquired position information estimating and calculator; (121) Posture estimator; (122) Directional angle estimator; (123) Height estimator; (124) Walk detecting and step estimator; (125) Digital filter; (130) Position data display part; (140) Position data communication part
