Classify ground points
« on: October 13, 2014, 03:49:09 PM »
Hi,

Does anyone know how to use the Classify ground points functionality from python?

I can't seem to find anything about it in the manual...

Hello MINE,

Dense cloud classification function has been implemented in Python in PhotoScan v 1.1 build 1982:
Code: [Select]
chunk.dense_cloud.classifyGroundPoints(max_angle=15.0, max_distance=1.0, cell_size=50.0)

To build model based on certain classes optional [classes] argument in chunk.buildModel() function should be used, where indices of the point classes should be specified.

Can you give an example of what this looks like?

Hello tforward2,

Using classes argument with the list of class indices works in the following way:
Code: [Select]
chunk.buildModel(classes = [3,5])It means that only Low Vegetation and High Vegetation class points will be used for the mesh generation.
