To solve the problem that there are many cases of causing portions that cannot be measured by three-dimensional measurement using measuring equipment installed on heavy machine used in conventional construction work.SOLUTION: A three-dimensional information processing device includes: an acquisition unit that generates a plurality of three-dimensional point cloud data from a plurality of three-dimensional measurement results; an extraction unit that extracts identical feature points between the plurality of three-dimensional point cloud data; a synthesis unit that aligns the plurality of three-dimensional point cloud data based on the identical feature points and generates one three-dimensional point cloud composite data; a generation unit that generates three-dimensional mesh data from design drawing data to which position coordinate values are set; an import unit that sets position coordinate data in the three-dimensional point cloud composite data; an identification unit that generates pre-difference-calculation data that identifies difference data between the three-dimensional mesh data and the three-dimensional point cloud composite data; a calculation unit that performs calculation processing based on information of the pre-difference-calculation data to generate difference data; an output unit that outputs a difference calculation result based on the difference data; and a display unit that displays the difference calculation result.SELECTED DRAWING: Figure 3 【課題】従来の施工に用いる重機に設置した計測機器による３次元計測だけでは計測不能箇所が発生するケースが多い。【解決手段】３次元情報処理装置に、複数の３次元計測結果から複数の３次元点群データを生成する取得部と、前記複数の３次元点群データ間の同一特徴点を抽出する抽出部と、前記同一特徴点を基に前記複数の３次元点群データ間を位置合わせし一つの３次元点群合成データを生成する合成部と、位置座標値を設定した設計図面データから３次元メッシュデータを生成する生成部と、位置座標データを前記３次元点群合成データに設定する取込部と、前記３次元メッシュデータと前記３次元点群合成データ間の差分データを特定した差分算出前データを生成する特定部と、前記差分算出前データの情報に基づき演算処理し、差分データを生成する演算部と、前記差分データを基に差分算出結果を出力する出力部と、前記差分算出結果を表示する表示部と、を備えた。【選択図】図３
