Characteristic point coordination system, characteristic point coordination method, and recording medium

摘要

Provided is a characteristic point associating system including: a set creating unit to receive a plurality of characteristic point groups to be compared, and to create a plurality of characteristic point pair sets by grouping together characteristic point pairs that are close to one another in terms of local conversion parameter into sets; a set selecting unit to select a characteristic point pair set that contains many elements out of the plurality of characteristic point pair sets; and a corresponding characteristic point determining unit to determine out of characteristic point pairs contained in the selected characteristic point pair set, a pair of characteristic points to be associated with each other as correct corresponding characteristic points so as to be output. Thus, the characteristic point associating system associates correct pairing combinations of characteristic points that exist between the compared groups of characteristic points.
