*This abstract for appeared for patent application  number 17687375 Titled 'INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND STORAGE MEDIUM'

==Simplified Explanation==

The abstract describes an information processing apparatus that generates a map element based on the position and orientation of an image capturing apparatus and three-dimensional position information of a feature point in an image. It then generates three-dimensional map information using multiple map elements at different positions and orientations. The apparatus corrects the position and orientation of the image capturing apparatus and the three-dimensional position information to minimize the reprojection error of a common feature point in a first group of map elements. It also corrects the position and orientation using a second group of map elements to further minimize the reprojection error of the common feature point.


==Original Abstract Submitted==

An information processing apparatus generates a map element that is based on a position and orientation of an image capturing apparatus and three-dimensional position information about a feature point included in an image, generates three-dimensional map information based on a plurality of map elements at a plurality of different positions and orientations, corrects, in such a way as to make smaller a reprojection error of a common feature point in a first map element group, at least one of a position and orientation of the image capturing apparatus and the three-dimensional position included in the first map element group, and corrects, in such a way as to make smaller a reprojection error of the common feature point with use of a second map element group, at least one of a position and orientation of the image capturing apparatus and the three-dimensional position information included in the second map element group.
