【摘要】 无协作目标电子全站仪无需反射目标而能测定待测点空间位置 ,利用其这一特点 ,对难以安置反射棱镜或反射片的建筑物立面 ,采用自由设站法测定墙面均匀分布的点位 ,经过坐标变换拟合出墙面的平面方程 ,能够直观地评定墙面的质量以及变化情况。实践证明该方法快速、准确 ,在建筑物立面等的检测中有良好的应用前景更多还原

【Abstract】 Reflectorless total station can measure 3D coordination without any reflector.For those building surface which is difficult to set sheet or prism on it,we can solve the problem according to the following steps.Firstly, get coordinates of the points which located evenly on the wall using Free Station method.Secondly, obtain the plane equation after the coordination transformation and coincidence-least square.Finally we can directly appraise wall quality and change from the difference between real value and coincidence value in the direction which is normal to the building vertical surface. Practice proved that this method is quick and accurate and has a bright application future in the building quality check such as building vertical surface.更多还原
