Claims (1)
- 測距光を出射し、測定対象物表面で反射した測距光を受光して前記測距光の前記測定対象物表面の照射点までの距離を測定する測距部と、望遠鏡の基準方向からの角度を検出する測角部と、前記望遠鏡を回転させるモータとを備えた表面形状測定機において、
所定平面内にX軸を取り、前記平面と直交方向にZ軸を取ったXZ座標系で、X軸上の選択した点を通り前記所定平面に垂直な直線と前記平面上に配置された測定対象物表面との交点の予想座標値を算出する予想座標算出手段と、前記予想座標値の点に前記望遠鏡を向けるための前記望遠鏡の回転角を算出する回転角算出手段と、前記回転角だけ前記望遠鏡を回転させる望遠鏡回転手段と、前記予想座標値の点に向けて測距光を出射させて前記照射点までの距離測定を行う距離測定手段と、前記照射点までの距離及び前記測角部で検出した角度から前記照射点の座標値を算出し、前記照射点と前記選択した点との間のX座標値の差を算出するX座標差算出手段と、前記X座標値の差が所定範囲内のときに、前記予想座標値を選択した点を通り前記所定平面に垂直な直線と前記測定対象物表面との交点の座標値として記憶する座標記憶手段とを備え、
前記予想座標算出手段は、
測定対象物を所定水平面内でメッシュに区切り、所定水平面内において選択した交点と表面形状測定機の真下の点を通るようにX軸を取り、表面形状測定機を通るように鉛直方向にZ軸を取ったXZ座標系で、
1回目の測定は、選択した交点の座標を交点の真上の盛土表面の予想座標の点P1と仮定し、2回目の測定があれば、交点の真上で盛土表面における測距光の照射点Q1と同じ高さの点P2の座標を予想座標とし、3以上のn回目の測定があれば、照射点Qn―2と照射点Qn―1の座標値から、照射点Qn―2と照射点Qn―1の間での盛土表面の平均勾配を求め、交点を通る鉛直線と照射点Qn―2と照射点Qn―1を通る直線の交点Pnの座標を予想座標とすることを特徴とする表面形状測定機。
