Abstract
A method of creating an indoor environment map includes acquiring encoded position information by detecting revolutions of wheels when a mobile unit travels using encoders to predict a position of the mobile unit based on the encoded position information, acquiring a measured distance from the mobile unit to an object existing in a surrounding environment using the distance measuring sensor, predicting a position of the mobile unit to be moved, estimating a distance from the mobile unit to the object at the predicted position of the mobile unit, determining whether the estimated distance is matched with the measured distance, correcting the predicted position of the mobile unit to estimate a position of the mobile unit to be moved by the matching of the predicted position with the measured position, and creating the indoor environment map using the corrected position and the measured distance.
