Using Created (never classified) in Classify Ground Points
« on: August 04, 2021, 03:55:18 PM »
Context: I'm trying to reclassify ground points without doing Reset Classification.

My assumption: Using "Created (never classified)" as source ("From") in "Classify Ground Points" should do the same job as "Reset Classification" and selecting source as "Any Class"

Output: This setting tries to classify ground points on top of previously classified points instead of doing a fresh new classification.

Please clarify if my assumption is correct or if this is a bug.
My requirement is to do "Reset Classification" in Python API but I don't see a function to perform this action. So, I used "Created (never classified)" as source points. But output is not what I expected it to be.

Hello srivatsa_s,

If you would like to start the classification with the new parameters from scratch, you should reset previously acquired classification results. Via Python it can be done using the following command, which assigns "Created (Never classified)" class to all the points in the active dense cloud:
Code: [Select]
chunk.dense_cloud.assignClass(0)
