The point cloud contains a row of continuous trees. I want to segment individual trees. Kindly help. I tried it by distance, there are death trees inbetween.

Can you define the data in the IAS and CSV files? What does each column mean?

Hello,
I understand you have point cloud data for a row of trees and would like to segment the individual trees and extract their attributes.
I’ve attached an example which describes the segmentation process below.
Note that you will have to convert the unorganized point cloud data to organized point cloud.
In case you would like to use the unorganized pcd, you can try the following steps as a workaround.
- Use statistical measures like ‘min’ of data to manually remove ground data points and apply “pcsegdist” function to get better segmentation results.
- Classify the segments into dead trees by comparing statistics like ‘mean’ of height, or ‘std variance’ of width.
- In case using “pcsegdist” once is not yielding good results, you could try applying it again on the obtained segments but with finer value of ‘minDistance’ parameter.
Please refer to the following documentation link for further information on “pcsegdist” function.
I hope this helps.
