Zusammenfassung:To acquire an effective measurement result to an operator while using three-dimensional point group data in construction limit measurement that targets a building or the like.SOLUTION: A vehicle type 3D model M1 being a three-dimensional graphic model is created and prepared in a database DB, and three-dimensional measurement is performed by using a laser scanner LS from above a station PF. A rail track data RM is determined in a three-dimensional image obtained from the three-dimensional point group data, and the vehicle type 3D model M1 is arranged on the rail track RM. A construction limit space area N1 is defined by the vehicle type 3D model M1 arranged on the rail track RM, and a separation distance between the construction limit space area N1 and the station PF (an edge part of a roof PM in particular) is calculated. Then, information of the separation distance is made into an image to the three-dimensional measurement image from a visual point that can overview the entire construction limit space area N1 (vehicle type 3D model M1), and a superimposed visualization image is displayed.SELECTED DRAWING: Figure 1 【課題】建物などを対象とする建築限界測定において、3次元点群データを利用しながら、オペレータに対して有効な測定結果を得るようにする。【解決手段】3次元グラフィックモデルである車両型3DモデルM1をデータベースDBに作成、用意し、駅PFの上からレーザスキャナLSを用いて3次元計測を行う。3次元点群データから得られる3次元計測画像において、線路データRMを定め、車両型3DモデルM1を線路RMの上に配置する。線路RM上に配置された車両型3DモデルM1によって建築限界空間領域N1が規定され、建築限界空間領域N1と駅PF(特に、屋根PMの縁部分)との離隔距離が求められる。そして、建築限界空間領域N1(車両型3DモデルM1)全体を俯瞰できる視点からの3次元計測画像に対し、離隔距離の情報をイメージ化し、重ね合わせた可視化画像を表示する。【選択図】 図1
