Classify point cloud by color
I am a long time Global Mapper user but new to Version 17 and the LiDAR module.
We are looking ways to classify point clouds created with drone based photogrammetry.
I would like to be able to classify points according to colour.... the long way to achieve this would be to complete a series of RGB value searches to refine my selection to a specific spectrum.
The problem with this is that I need to know the range of RGB values in advance.
What would be nice would be able to select a point and a "tolerance" to find points of "similar" color.
I haven't been able to find this functionality yet?
Am I missing something here??
If it's not currently part of GM, has anyone written a script that does something similar??

I too would like to classify by color.
In a related question, I would like to remove points based on color. In the Filter points option in auto classification, I see a way to keep points with certain color values. How can I do the reverse? -
As another uav operator doing Photogrammetry, this is very interesting. Has it been implemented?

me too.
