摘　　要：将地面三维激光扫描技术运用于城市特定建筑物的面倾斜变形监测中,解决了传统观测手段监测速度慢的问题。完成点云数据的曲面拟合,运用GMT绘制面变形矢量图,顾及点云测量精度的影响,其倾斜变形趋势与传统测量方法所得结果保持一致。Using terrestrial laser scanning technology in the city specific building surface tilt deformation monitoring,can improve the efficiency of traditional monitoring methods.We completed the surface fitting through point cloud at first,and then used GMT method to draw the surface deformation vector drawing.The results of surface monitoring obtained by TLS were consistent with the results obtained by the traditional method.
