Abstract
An information processing device, including: a three-dimensional information generating section for obtaining position and attitude of a moving camera or three-dimensional positions of feature points by successively receiving captured images from different viewpoints, and updating status data using observation information which includes tracking information of the feature points, the status data including three-dimensional positions of the feature points within the images and position and attitude information of the camera; and a submap generating section for generating submaps by dividing an area for which the three-dimensional position is to be calculated. The three-dimensional information generating section obtains position and attitude of the camera or three-dimensional positions of the feature points by generating status data corresponding to the submaps not including information about feature points outside of a submap area for each of the generated submaps and updating the generated status data corresponding to the submaps.
