Hello ppkong,

You are trying to classify the Dense Cloud class and not the existing dense cloud.
If there's a chunk (for example active chunk: chunk = PhotoScan.app.document.chunk) you should use chunk.classifyGroundPoints() function.

Hey

I was having the same problem so I tried what you suggested but had no luck.
I'm getting the following error:

Code: [Select]

AttributeError: 'PhotoScan.Chunk' object has no attribute 'classifyGroundPoints'
Any suggestions?
Thanks

Found the answer

Code: [Select]

chunk.dense_cloud.classifyGroundPoints(max_angle=max_angle, max_distance=max_distance, cell_size=cell_size)
