THREE-DIMENSIONAL MAP GENERATION SYSTEM, THREE-DIMENSIONAL MAP GENERATION METHOD, AND COMPUTER READABLE MEDIUM

A three-dimensional map generation system () generates three-dimensional map information () by using measured data acquired by a measurement vehicle () moving in a measurement area (). A determination unit () determines, from the measurement area (), a data shortage area where measured data for generating the three-dimensional map falls short, based on first measured data () transmitted from the measurement vehicle (). A generation unit () 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 ().
