摘要
由于已有的测量误差模型不能准确地表达激光扫描仪虚拟测方系统在空间数据采集和融合过程中的误差传播规律,在误差来源分析的基础上,研究设计了用于激光扫描仪虚拟测方系统及相似测量系统的误差传播模型,并结合实例讨论了影响测量精度的因子,得出了不同曲面构造方法的误差特征。
As the existing measurement error model cannot accurately express the error propagation of the laser scanner virtual volume-measuring system in the process of acquisition and integration of spatial data. Based on the error source analysis,an error propagation model is designed for the system,and is applied to the similar volume-measuring system.Factors affecting the measurement accuracy are discussed with examples, the error characteristics of different surface construct method are obtained.
