C3DC

List of commands

Description

C3DC is used for Automatic Matching from Culture 3D Cloud project. The C3DC command is the command that compute automatically a point cloud from a set of oriented images.

Syntax

The global syntax for C3DC is :

mm3d C3DC EnumeratedValues FullName Orientation NamedArgs

Allowed commands

• Ground
• Statue (ZoomF=2 (high preset with less noise), [[1]])
• Forest
• TestIGN
• QuickMac (ZoomF=8 (low preset 1pt/64px), [[2])
• MicMac (ZoomF=4 (medium preset 1pt/16px), [[3])
• BigMac (ZoomF=2 (high preset 1pt/4px), [[4])
• MTDTmp

Help

You can access to the help by typing :

mm3d C3DC -help

Mandatory unnamed args :

• string :: {Type in enumerated values}
• string :: {Full Name (Dir+Pattern)}
• string :: {Orientation}

Named args :

• [Name=Masq3D] string :: {3D masq for point selection}

• [Name=Tuning] bool :: {Will disappear one day ...}
• [Name=Purge] bool :: {Purge result, (Def=true)}
• [Name=DownScale] REAL :: {DownScale of Final result, Def depends on mode}

• [Name=ExpImSec] bool :: {Export Images Secondair, def=true}
• [Name=OffsetPly] Pt3dr :: {Ply offset to overcome 32 bits problem}

QuickMac

The QuickMac uses the MMInitialModel as matcher, which is quite fast on CPU.

Example

For example, in the Mur Saint Martin dataset, you can launch :

mm3d C3DC MicMac "IMGP.*JPG" MEP-Terrain Masq3D=AperiCloud_MEP-Terrain.ply Out=C3DC_MicMac_MurSaintMartin.ply
