3D map generation system, 3D map generation method and 3D map generation program

摘要

A three-dimensional map generation system (500) generates three-dimensional map information (11) by using measured data acquired by a measurement vehicle (200) moving in a measurement area (50). A determination unit (120) determines, from the measurement area (50), a data shortage area where measured data for generating the three-dimensional map falls short, based on first measured data (20) transmitted from the measurement vehicle (200). A generation unit (130) generates interpolated data which interpolates three-dimensional map information of a defective area with a NURBS curve so that a lateral G, which is centrifugal force in a lateral direction applied to a traveling vehicle traveling a road in the defective area at a traveling speed, is equal to or less than a predefined threshold (12).
