Exception point of skeleton data

[pengssy1]

Hi,

I got the skeleton data using your methods. But for some individual tree skeleton data, I found some exception point. For example, the point at the red arrow. My original point cloud has not these exception point. The reason from Laplcian or else?

Cross fingers!

My first guess is that some points get contracted to some centers. I have also encountered the same behavior. My quick hack was too just delete points which all have the same coordinate (Mostly this are 100 of points in the same little region or all in (0,0,0)). What position do your points have?

[pengssy1]

These are position of exception point. So, accually, only mannualy remove these points?

You could also use open3d's remove statistical outlier function to remove these points.

ok. Thanks!
