| Abstract: | In the application of acquiring digital terrain model,extracting buildings and road with LIDAR points,the filtering of LIDAR data is necessary,which means segmenting ground points and non-ground points.In a narrow plot,ground can be hypothesized a planar plane,so the planar constraint can be used to acquire planar points.The next processing is classifying planar points into ground points and non-ground points with the help of planar points'height statistic,and finally,DTM is interpolated by ground points. |
