SYSTEM FOR SPECIFYING BANKING STRUCTURE FORM WITH HIGH ACCURACY AND BANKING STRUCTURE CONSTRUCTION METHOD WITH HIGH ACCURACY
To provide means to specify a form of a banking structure using a GNSS with higher accuracy than a conventional technique.SOLUTION: When constructing a banking structure, an operator operates a construction vehicle to bulldoze and spread material, and compacts the material. A server device receives a three-dimensional coordinate (first coordinate) indicating the position measured by a GNSS unit 12D installed on the construction vehicle during construction of the banking structure from the GNSS unit 12D. The server device first calculates a coordinate (second coordinate) of a work point at which the construction vehicle contacts the surface of the banking structure from the first coordinate without considering the inclination α of the construction vehicle. The server device specifies a flat surface to approximate many second coordinates that were previously calculated. Subsequently, the server device calculates the coordinate (third coordinate) of the work point in consideration with an inclined direction of the specified flat surface from the first coordinate. The server device specifies the flat surface to approximate many third coordinates calculated in such a manner as the flat surface that expresses the current finished form of the banking structure correctly.SELECTED DRAWING: Figure 8
【課題】ＧＮＳＳを用いて従来技術と比較し高い精度で盛土構築物の形状を特定する手段を提供する。【解決手段】盛土構築物の構築において、作業者は工事車両を操縦して材料を撒出し、敷きならし、締固め等を行う。サーバ装置は盛土構築物の構築が行われる間に工事車両に設置されたＧＮＳＳユニット１２Ｄが測位した位置を示す３次元座標（第１の座標）をＧＮＳＳユニット１２Ｄから受信する。サーバ装置は、第１の座標から、まずは工事車両の傾きαを考慮せずに、工事車両が盛土構築物の表面と接する作業点の座標（第２の座標）を算出する。サーバ装置は過去に算出した多数の第２の座標を近似する平面を特定する。続いて、サーバ装置は、第１の座標から、特定した平面の傾斜方向を考慮して、作業点の座標（第３の座標）を算出する。サーバ装置は、そのように算出した多数の第３の座標を近似する平面を、盛土構築物の現状出来形を正しく表す平面として特定する。【選択図】図８
