LOCATION ESTIMATION SYSTEM AND A METHOD OF A MOVING OBJECT CAPABLE OF ACCURATE LOCATION TRACKING THROUGH A CURRENT PROCESS STEP RECOGNITION OF A USER

摘要

PURPOSE: A location estimation system and a method of a moving object are provided to accurately estimate a current location of a moving object by correcting current location information of a moving object based on the obtained current location of a user after obtaining a current location of a user based on the recognized process step.;CONSTITUTION: A moving object(10) accesses a location estimation server(20) through a wireless internet network(S10), and transmits login information for permission of a user to the accessed location estimation server(S12). An absolute location estimation unit of the moving object calculates an initial reference location of the moving object according to the absolute location estimation method(S14). A relative location estimation unit calculates relative location variation according to movement of the moving object(S16). A current location estimation unit estimates a current location of itself based on the initial reference location provided from the absolute location estimation unit(S18). A process recognition unit obtains current absolute location information of the moving object by searching for database(S26). A location correction unit corrects a current location of the moving object(S30). A current location estimation unit sets up the corrected current location of the moving object as the reference location(S32), and estimates a current location of itself based on the set reference location and the relative location(S34).;COPYRIGHT KIPO 2013;[Reference numerals] (10) Moving object; (20) Location estimation server; (S10) Access; (S12) Login information; (S14) Calculate an initial reference location; (S16) Calculate a relative location; (S18) Estimate the current location; (S20) Authenticate a user; (S22) Set a process; (S24) Recognize the current process step of the user; (S26) Obtain the absolute location information of the moving object; (S28) Absolute location information of the moving object; (S30) Correct the current location of the moving object based on the absolute location information of the moving object; (S32) Set the corrected current location of the moving object as a reference location; (S34) Estimate the current location
