CIVIL ENGINEERING STRUCTURE FINISHED SHAPE EVALUATION SYSTEM, FINISHED SHAPE EVALUATION METHOD AND PROGRAM
PROBLEM TO BE SOLVED: To improve accuracy and efficiency of a civil engineering structure finished shape evaluation by using three-dimensional measurement data.SOLUTION: A civil engineering structure finished shape evaluation system 2 evaluates a finished shape on the basis of three-dimensional coordinate data consisting of a point group measured from a surface of the finished shape of a target civil engineering structure. The civil engineering structure finished shape evaluation system 2 comprises: a memory device 6, which preliminarily stores design data 30 of a three-dimensional design configuration of the target civil engineering structure; and an evaluation part 20, which provides attributes representing deviation from the design configuration to each element point of the point group. The evaluation part 20 defines an attribute value of the attribute on the basis of the result of determining whether or not the element point is included in a space sandwiched between two boundary surfaces that are formed by moving the design configuration surface in parallel in one direction and the other direction of a predetermined direction by predetermined off-set distance.SELECTED DRAWING: Figure 1
【課題】３次元測量データを用いて土木工事の出来形評価の精度、効率の向上を図る。【解決手段】土工出来形評価システム２は土木工事の工事目的物の出来形の表面から計測された点群の３次元座標データに基づいて出来形を評価する。土工出来形評価システム２は、工事目的物の３次元の設計形状についての設計データ３０を予め記憶する記憶装置６と、点群の各要素点に、設計形状からの乖離を表す属性を付与する評価部２０とを有する。評価部２０は、設計形状の表面を所定方向の一方向きと他方向きとにそれぞれ所定のオフセット距離ずつ平行移動した２つの面を境界面として、当該境界面に挟まれる空間内に要素点が含まれるか否かの判別結果に応じて属性の属性値を定義する。【選択図】図１
