车载激光扫描数据控制点布设方案研究

Study on Layout Scheme of Control Points in Vehicular Lidar Data

摘要:

该文以提高车载激光扫描数据高程精度为出发点，分析了扫描数据的误差来源。该文提出多种控制点布设方案，以京沪高速部分路段激光扫描数据为例，统计并分析各个控制点布设方案改正结果，为以后车载激光数据外业控制点布设提供参考。

Abstract:

On the basis of improving the elevation precision of vehicle laser scanning data, deviation sources of scanning system have been analyzed. In this paper, a layout scheme of a variety of control points has been put forward. Setting laser scanning data of BeijingShanghai high speed road as an example, correcting results of the layout scheme of each control point have been statisticed analyzed. It will provide some references for the layout of control data in the field of vehicle laser scanning data.
