The 3D textured mesh will be generated using the point cloud. The resultant point cloud is then post-processed to extract mapping data, roadside asset In both the above cases, the 3D point cloud data captured is very dense and huge in size along with the photographs. Filtering Point Cloud Filtering the point cloud into ground and non-ground returns is the core component of a lidar data processing software. To decrease interpolation errors, a few researchers have presented other algorithms for processing the LIDAR raw data point cloud to generate a DTM. Why is that? The main reason is that the points themselves are not all that useful to most people. Use FME to process and integrate point clouds with the rest of your data. The photogrammetric point cloud consists of slightly over 13 million points, and for the Lidar point cloud this number is nearly ten million. Data processing can also introduce additional errors into a point cloud, but generally it will bring a point cloud into a much higher level of accuracy than the originally captured point cloud, depending on the applied processing procedures.
