Export mean density of point cloud

Post by fcoud »

Hello,

I am trying to export the density values of my point cloud.
I found the following tool " Tools->Other->Density", which returns a scalar field containing local densities (number of points per m3 if I am not mistaken, with r=1).

But I am looking for a mean density of the cloud, not local densities. Therefore, I want to export the scalar field density to try and compute a mean of these values. I tried saving my cloud as a ".laz", but when I open it again, I cannot find the density values...

Could anyone tell me how to export this scalar field density ?
If any of you were to know a better method to compute a mean density of my point cloud, I would be very interested.

Thanks
daniel

You can simply use the 'Edit > Scalar fields > Compute stat. params' and choose the Gaussian/Normal distribution. You'll get the average value (among other parameters).

And to export all values, simply export the cloud as an ASCII/text file. You'll be able to load it easily in another tool (Excel, Matlab, etc.)
