Abstract: A three-dimensional point cloud densification device includes: an obtainer that obtains a plurality of three-dimensional points, each of which indicates a three-dimensional position of at least one object, and auxiliary information for creating a polygon; and a densifier that: identifies the polygon having, as vertices, at least three three-dimensional points among the plurality of three-dimensional points, based on the auxiliary information; and generates a new three-dimensional point inside the polygon.
