PROBLEM TO BE SOLVED: To provide a high speed and effective map extention method in an extended reality sensing system.SOLUTION: On a plurality of vide frames picked up by a camera 120, a feature group in which a map point group in a three-dimentional space is projected is determined, and a histogram of the determined feature group is generated for a plurality of areas in the frames. On the basis of the generated histogram, one of the plurality of areas is determined as a non-observation area. On the basis of the size of the non-observation area, the frames are selected. |
