Operate Ransac on tree

Post by guysadot »

Hey all
My cloud contain combined ALS and TLS point cloud.
My goal is to segment the stem, floor and the rest (suppose to be the leaf) with Ransac.
I tried and got much more then one cylinders and planes.
Does anyone have experience with the parameters needed to be fill before?
Picture Added for reference.

Thanks!

You can maybe play with the minimum number of points? (depending on how dense is your cloud of course)

Hey Daniel, sorry for the late answer
In my case, the point density varies a lot. the lower side is much denser than the higher.
I tried to set Min Radius, and it helped a bit but still, the output is not good enough.
have you familiar with the parameters on the right side?
Thanks again!
