Nuage2Ply

List of commands

Description

Nuage2Ply is used to convert a depth map (or DEM when applicable) to a point cloud in ply format. The color of an image can be projected to the points (option "attr"). In case of a DEM (classically computed by "Malt Ortho"), the ortho-image mosaic computed by Tawny can be used.

Syntax

The global syntax for Nuage2Ply is
mm3d Nuage2Ply XMLFile NamedArgs

Help

You can access to the help by typing :
mm3d Nuage2Ply -help

Mandatory unnamed args :

• string :: {Name of XML file}

Named args :

• [Name=Sz] Pt2dr :: {Sz (to crop)}
• [Name=P0] Pt2dr :: {Origin (to crop)}
• [Name=Out] string :: {Name of result (default toto.xml => toto.ply)}
• [Name=Scale] REAL :: {Do change the scale of result (def=1, 2 mean smaller)}
• [Name=Attr] string :: {Image to colour the point}
• [Name=Comments] vector<std::string> :: {Commentary to add in the ply file (Def=None)}
• [Name=Bin] INT :: {Generate Binary or Ascii (Def=1, Binary)}
• [Name=Mask] string :: {Supplementary mask image}
• [Name=SeuilMask] REAL :: {Theshold for supplementary mask}
• [Name=Dyn] REAL :: {Dynamic of attribute}
• [Name=DoPly] INT :: {Do Ply, def = true}
• [Name=DoXYZ] INT :: {Do XYZ, export as RGB image where R=X,G=Y,B=Z}
• [Name=Normale] INT :: {Add normale (Def=false, usable for Poisson)}
• [Name=NormByC] INT :: {Replace normal (Def=0, 2=optical center 1=point to center vector)}
• [Name=ExagZ] REAL :: {To exagerate the depth, Def=1.0}
• [Name=RatioAttrCarte] REAL
• [Name=Mesh] bool :: {Do mesh (Def=false)}
• [Name=64B] bool :: {To generate 64 Bits ply, Def=false, WARN = do not work properly with meshlab or cloud compare}
• [Name=Offs] Pt3dr :: {Offset in points to limit 32 Bits accuracy problem}
• [Name=NeighMask] string :: {Mask for neighboors when larger than point selection (for normals computation)}
• [Name=ForceRGB] bool :: {Force RGB even with gray image (Def=true because of bug in QT)}

Example

For example, with the Ramses dataset, you can launch :
mm3d Nuage2Ply NuageImProf_STD-MALT_Etape_8.xml Attr=../Ortho-MEC-Malt/Ortho-Eg-Test-Redr.tif RatioAttrCarte=2 Scale=2
