Hello Salman and Laurent,

 

Thanks for the help. I read what you have suggested and I guess that's it what I was asking for. I'll try the same.

 

Greetings,
Samay

Subject: Re: [cgal-discuss] How to filter noise of point cloud

Dear Samay,

first of all thank you for being interested in CGAL.
So the answer to your question is yes! And guess what
you can get it in CGAL :-)

It is called the Point Set Processing package:
This Cgal package [1] implements algorithms to analyze and process
unorganized 3D point sets. The input is an unorganized 3D point set,
possibly with normal attributes (unoriented or oriented). The point
set can be analyzed to measure geometric properties such as average
spacing between points and their k-nearest neighbors. It further
offers functions devoted to the simplication, outliers removal,
smoothing, normal estimation and normal orientation.

The processing of point sets is often needed in case of 3D point
clouds extracted by dense multi-view stereovision or being
acquired through laser devices.

And i basically use it personally for passive multi-view stereo
point clouds which are rather far from the range scan quality...

So please if you encounter any kind of problems i'd be glad to provide
some help.

Best,

Nader Salman
