To provide a construction gauge measuring device capable of measuring a construction gauge with high accuracy.SOLUTION: A construction gauge measuring device includes: a data acquisition unit for acquiring three-dimensional point group data in that a shape of an object existing in a periphery of a track is shown by a three-dimensional point group and track center line data of rails scanned by a laser scanner provided on a measurement vehicle in a traveling direction of the measurement vehicle traveling on two rails; an area storage unit for storing area data showing a two-dimensional construction gauge area of a determination target vehicle when it is arranged on the three-dimensional data; an area arrangement unit for sequentially arranging a plurality of construction gauge areas according to the track center line data based on the area data of the area storage unit; an area change unit for changing the construction gauge areas arranged based on additional information of the rails associated with the track center line data; a connection area generation unit for generating a connection area connecting the plurality of construction gauge areas changed by the area change unit; and a detection unit for determining whether or not the three-dimensional point group data acquired by the data acquisition unit is included in the connection area so as to detect an obstacle with respect to the traveling of the determination target vehicle.SELECTED DRAWING: Figure 2

    【課題】精度の高い建築限界の測定が可能な建築限界測定装置を提供する。【解決手段】建築限界測定装置は、2本の軌条を走行する計測車両の走行方向において、計測車両に設けられたレーザスキャナからスキャンニングした軌道周辺の物体の形状を3次元点群で表す3次元点群データおよび軌条の軌道中心線データを取得するデータ取得部と、3次元点群データ上に配置する場合の判定対象車両の2次元の建築限界領域を示す領域データを記憶する領域記憶部と、領域記憶部の領域データに基づいて建築限界領域を軌道中心線データに従って順次複数配置する領域配置部と、軌道中心線データに関連付けられている軌条の付加情報に基づいて配置された建築限界領域を変更する領域変更部と、領域変更部により変更された複数の建築限界領域を連結した連結領域を生成する連結領域生成部と、判定対象車両の走行に対する障害物を検出するために連結領域内にデータ取得部で取得した3次元点群データが含まれる否かを判断する検出部とを備える。【選択図】図2
