Hello,

 

I am new to CGAL and have been trying to adjust it for my own purpose. My aim is to detect all the reference spheres (with known size, radius =7.25cm) in a huge point cloud (40 millions). I use the efficient RANSAC functions in the Shape Detection Examples. However, I did not find out any method to define the size of the model. I added the following code into “Sphere.h” to select the radius within the range:

 

//****************************************

      if (radius > 0.08 || radius < 0.06) {

          this->m_is_valid = false;

          return;

      }

      //****************************************

 

With this code, I can only choose some spheres from the spheres who are already detected. Which means, I will still get the same results.

I would like to know, is there any possibilities in CGAL that I can detect a certain sized model? More like fitting a model to the point clouds.

 

Thanks in advance.

 

Regards.
