Cloth Simulation method for DTM point classification
« on: February 25, 2017, 03:45:49 PM »
You should implement Cloth Simulation method for point classification. This is especially good for classification ground and non-ground points like in high density city to create DTM.

Scientific paper: "An Easy-to-Use Airborne LiDAR Data Filtering Method Based on Cloth Simulation" Zhang W, Qi J, Wan P, Wang H, Xie D, Wang X, Yan G.: http://www.mdpi.com/2072-4292/8/6/501

+1, I've been using it on raw point cloud exports with great success, this point classification method is a gem.
Best regards.

Would there be a way to incorporate this as a python script? This sounds like something I would be very interested in

Hello CamMakoJ,
Wuming Zhang, the leader of the team that developped CSF, posted the Python script on Github.

Make sure to follow his amazing project on ResearchGate!
Best regards.

Thats awesome thanks! - Is this script runnable from within Agisoft? i have tried all of the python scripts in that folder. I only ask because once we take a dense cloud out of agi i cant put it back in to create a model.

I too would like to know if this can be ran in agisoft, and if so how, are there any instructions anywhere ?

The "cloth" method seems like a fantastic tool for determining bare earth points.  However, Agisoft doesn't seem too interested for reasons they have not mentioned.  But it has been asked for.

+1 for cleaner DTMs
