摘　　要：针对变形监测场景中存在大量的平面特征,提出一种基于阈值判别变形和正态分布模型提取变形相结合的点云特征面变形分析算法,给出了算法的实施步骤。通过模拟实验验证了算法的可行性,结果表明,该算法提取结果精度较理想,在对具有平面特征的变形监测应用上有一定的应用空间。An analytical algrithom is represented based on de- formation discriminated by threshold and determined by nor- mal distribution models and the detailed process is also clari- fied.The feasibility of this algrithom is ioroven through sim- ulation experiment indicating the result is precise and thus deformation monitoring with plane features.
