ALTITUDE DIFFERENCE DETECTION METHOD, ALTITUDE DIFFERENCE DETECTION SYSTEM, AND ALTITUDE DIFFERENCE DETECTION PROGRAM
To enable a repair point that requires repair to be accurately specified at commencement of repair work.SOLUTION: An altitude difference detection method pertaining to the present invention comprises: a point cloud data acquisition step for acquiring, by a laser beam irradiated from a three-dimensional scanning device installed at a known point, the three-dimensionalized point cloud data of each point in a prescribed region of road surface at commencement of repair work; a base level data acquisition step for acquiring plan level data that indicates a repair plan level when the prescribed region is repaired; and an altitude difference calculation step for calculating an altitude difference for each of the same level position within the prescribed region on the basis of the point cloud data acquired in the point cloud data acquisition step and the plan level data acquired in the base level acquisition step.SELECTED DRAWING: Figure 1
【課題】補修起工時において補修が必要である補修箇所を正確に特定可能にする。【解決手段】本発明の標高差検知方法は、既知点に設置された３次元走査装置から照射されるレーザ光により、補修起工時における路面の所定領域内の各点について３次元座標化された点群データを取得する点群データ取得ステップと、所定領域を補修する際の補修計画面を示す計画面データを取得する基準面データ取得ステップと、点群データ取得ステップで取得された点群データと基準面取得ステップで取得された計画面データとに基づいて、所定領域内の同一の平面位置ごとに標高差を算出する標高差算出ステップとを備える。【選択図】図１
