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。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 for-ward.Setting laser scanning data of Beijing Shanghai high speed road as an example,correcting results of the lay-out 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.
