How to create intensity image using point cloud in FME software? I already generate using image rasterizer transformer but the quality still need to be improved. Is there any other transformer that can give better result? I attached sample between intensity image generated from TerraScan and FME. Intensity created from FME is not very smooth compare to intensity generate from Terrascan. I also having problem with contrast balance which I think can be solved at FME. intensity generate from Terrascan[![][1]]2

  • Can you edit the question to be clearer what you need? What do you mean by "quality still needs to be improved"? Are you trying to create a raster heatmap from PointCloud data? – GIS-Jonathan Apr 19 '16 at 9:09
  • PointCloudFilter is a good start safe.com/transformers/point-cloud-filter – Mapperz Apr 21 '16 at 13:57

Did you check Creating a Raster from a Point Cloud tutorial from FME Knowledge center? It gives information on how to smooth your output, if this is what you need.

The RasterDEMGenerator transformer might be a better fit here. It will interpolate values, whereas the NumericRasterizer is just setting a cell on/off depending on the presence of points in it.

Alternatively you could increase the spacing in the NumericRasterizer - to about 2x larger than the average spacing of points in the point cloud.

Hopefully one of those solutions will help.
