Point Clouds to Surface

[roycastanares]

Hello Everyone, 

 

I am now working on a project that requires me to extract surface from point cloud data gathered with FARO, can someone share insights on how to do this the easy way.

 

 

Right now, what am I doing is digitize this point clouds through Bentley Microstation. It's tiresome, so can anyone share process or software I can use that automatically recognize features such as walls and support columns.

 

 

Thanks in advance.

this is lidar data right?

 

you can use LAS tool in arcgis or ENVI to automation make surface data from point height data

@Lurker,

 

 

The data I have now is in .pts .pod or .xyz extension.  I've seen some software like meshlab, geomagic, etc. Can you recommend one that will suit in extracting parts of a building. Like extracting window/ walls and columns, thanks.

so this is a LAS data for what object? building ?

[roycastanares]

Yes, here's a reference,

We need to extract its dimension, like detailed engineering design, and to do so we need to make the surface first, from outside to inside. Maybe a tool that will let us build its inner and outer surface automatically will be of great help.

something like object extraction i guess, oh geez , it's more civil CAD rather than GIS

Many thanks for the advice, Yes I also tried CAD feature extraction.

@mark312. Will look forward on your suggestion. Thank you very much.

You can use some workflows, for example:

 

1. Automatic surfacing http://www.geomagic.com/en/community/videos/geomagic-studio-2013-automatic-surfacing/

2. Exact surfacing http://www.geomagic.com/en/community/videos/geomagic-studio-12-exact-surfaces/

3. Other approach is followed:

a. You have to create mesh

b. You can use repotology techniques,  for example:

You can use SAGA GIS.

 

I have managed to create DTM from point cloud using that software.

I'm beta testing http://www.LidarToDxf.com, it may or may not do what you want.
