| 摘 要： | 将三维激光扫描技术应用到变形监测中，对三维激光扫描测距、测角、光斑及配准误差进行分析，给出点云误差椭球模型。利用得到的误差椭球半轴长度和点位误差极限值的关系，推导点云变形可监测性指标。最终通过模拟的滑坡实验，验证了该变形可监测性指标的可行性。

| Abstract: | In this paper, the range, angle, spot and registration error are analyzed, and the point cloud error ellipsoid model is given. According to the relationship between the error ellipsoid half shaft and limit value of point error, the deformation monitorable indicator is deduced. The proposed method is verified according to the simulated landslide. |
