| Abstract: | The point clouds filtering based on scanning lines,which does not need to establish complex data structure,is not only simple in computation structure but also efficient in computation time.It is suitable for departing the terrain points and non-terrain points from the point clouds.In order to leave out the pre-processing before the filtering,a modified filtering of point clouds based on so called pseudo scanning lines by slope is proposed in this paper.The modified algorithm not only has the advantages of ... |
