INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND STORAGE MEDIUM - A simplified explanation of the abstract

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

Simplified Explanation

This 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 of the feature point to minimize reprojection errors in a first map element group. It also corrects the position and orientation using a second map element group to further minimize reprojection errors 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.
