PROBLEM TO BE SOLVED: To appropriately grasp a road surface shape with a small calculation amount in a device that grasps a road surface shape using data measured by a measurement device or the like.SOLUTION: A road surface shape measurement device of the present invention comprises a road surface information acquisition unit and a road surface shape determination unit. The road surface information acquisition unit acquires, for a plurality of points on road surface, road surface information consisting of a road surface position that is the position of a road surface on a reference plane SF that is separated into a plurality of divided areas G1-G87 and a road surface height that is the height of a road surface at the road surface position. The road surface shape determination unit estimates a surface shape for each of the divided areas using the road surface information included in the divided areas G1-G87 and thereby determines the shape of the whole or part of a road surface.SELECTED DRAWING: Figure 4 【課題】測定装置などにより測定したデータを用いて路面形状を把握する装置において、少ない計算量で適切に路面形状を把握する。【解決手段】路面形状測定装置は、路面情報取得部と、路面形状判定部と、を備える。路面情報取得部は、路面上の複数の点について、複数の区画領域Ｇ１〜Ｇ８７に分けられた基準平面ＳＦ上における路面の位置である路面位置と、当該路面位置における路面の高さである路面高さと、からなる路面情報を取得する。路面形状判定部は、区画領域Ｇ１〜Ｇ８７に含まれる路面情報を用いて、当該区画領域ごとに表面形状を推定することにより、路面の一部または全体の形状を判定する。【選択図】図４
