List of commands

Description

AperiCloud is used for generating a visualization of and sparse 3D model and cameras position, computed by Tapas for example.

Syntax

The global syntax for AperiCloud is :

mm3d AperiCloud FullName Orientation NamedArgs

Results

AperiCloud, generate a sparse 3D cloud (".ply") with the position and orientation of each camera. If you don't use "Out" option, the file will be stored in your working directory at the name : AperiCloud-Ori_Name.ply. You can use MeshLab to visualize the file.

Workflow

AperiCloud is a tool dedicated to visualization of orientations. So you can use it every times you process a orientation. When you have processed the final orientation, you can define a 3D mask with the ".ply" file generated by AperiCloud (SaisieMasqQT).
Previous Command : Tapas,GCPBascule,Campari
Next Command : SaisieMasqQT.

Help

You can access to the help by typing :

mm3d AperiCloud -help

Mandatory unnamed args :

• string :: {Full name (Dir+Pattern)}

Example

In example, you can launch this command in the Mur Saint Martin dataset :

mm3d AperiCloud «.*JPG » Out=MEP 

Known limitations

AperiCloud doesn't support 64 bits ply

Due to this limitations, it is recommended to use local or truncated coordinate. Or not to use AperiCloud after georeferencement in a projected coordinates system. Look to thread for an example and further information.
