Abstract
Provided is an information processing method for generating accurate map data by loop closing even when map elements where a loop is detected in a real space are close to each other. The method includes selecting a map elements group including at least one map element on each movement path, the at least one map element including sensor information included in each map element used to detect that the moving object has reached a location near a point a plurality of times, acquiring a relative position and orientation of at least one set of map elements in the map elements group, acquiring a relative position and orientation of the sensor between map elements corresponding to each movement path where the moving object has reached the location near the point the plurality of times, and correcting position and orientation information about the sensor included in each of the map elements.
