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 : not supported for now
  • Statue : stereoscopic (strictly epipolar mode (ie. best stereographic pairs)) with ZoomF=2, ie. high preset 1pt/4px (with less noise) [[1]]
  • Forest : stereoscopic (strictly epipolar mode (ie. best stereographic pairs)) with ZoomF=4, ie. medium preset 1pt/16px
  • TestIGN : not supported for now
  • QuickMac : multistereoscopic with ZoomF=8, ie. low preset 1pt/64px, [[2]]
  • MicMac : multistereoscopic with ZoomF=4, ie. medium preset 1pt/16px, [[3]]

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 :
