基于熵函数的点云变形可靠性评价指标确定

摘要

In this paper,the range,angle and registration error are analyzed.The error entropy model was constructed according to the concept of information entropy.The reliability index of deformation extraction was determined according to the relationship between error entropy and error limit.Eventually,the effectiveness of the method was validated according to the simulating and real landslide.%本文对三维激光扫描测距、测角及配准误差进行分析,利用信息熵的定义给出误差熵模型,并根据误差熵和误差极值的关系,确定变形提取可靠性评价指标.最终通过边坡变化状况进行分析,确定该方法的有效性.
