摘要:

背包式三维激光扫描系统具有效率高和精细度高等优势,该文从该系统的组成出发,深入分析了背包点云数据的误差来源,并通过设计实验对点云误差的分布进行了统计分析。结果发现,该系统中存在系统误差,其影响因素多且相互叠加。为解决该问题,该文基于多元线性回归算法,构建了附加系统参数的误差补偿模型,通过实例分析验证,该模型能够有效削弱系统误差对背包点云的影响,显著提高了背包点云的精度,为建筑物点云的后续处理提供了可靠的保障。

Abstract:

Backpack 3D laser scanning system has the advantages of high efficiency and accuracy. This paper studies from the composition of the system, analyzes the error sources of the backpack point cloud data in depth, and statistically analyzes the distribution of the point cloud error by designing experiments.It is found that there is systematic error in the system which influencing factors are many and superimposed on each other. In order to solve this problem, this paper constructs an error compensation model with additional system parameters based on multiple linear regression algorithm. Example analysis verifies that the model can effectively weaken the influence of the systematic error on the backpack point cloud, effectively improve the accuracy of backpack point cloud, and provide reliable guarantee for subsequent processing of building point cloud.
