| 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 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. |
