How is that increased confidence defined? I get an RMS with 3, 4, or 8 points. Is there a way to show or express the increased confidence with the more points I have?

Hello, I am trying to align my point clouds as accurately as possible. What is the difference between using 3 vs 4 equivalent points for cloud alignment. I see questions regarding both but I don't know what the difference is. Older versions of CC seem to require minimum of 3 while new versions seem ...

Hi Daniel, I am trying to conduct a volumetric change detection from my two point clouds. I have used the volume tool with CC but I am also interested in using the M3C2 and exporting the raster to analyze in R. When looking at the M3C2-PM I am getting a lot of noise (ranging from -10 to 10m of chang...

Sorry, subtracting is the wrong term with M3C2, but calculating the difference between two clouds. How do you limit the noise? Is there a step in running M3C2 that I can take? I have tried increasing the diameter of the normals and projection but I get the same thing.

Thanks

Hello, I am subtracting two point clouds and am finding some extreme errors in my M3C2 subtraction where there are no points located in the original point clouds. Here is the M3C2 difference between the two clouds. This projection is using the mesh 2.5D best fit with 1m max edge length to visualize ...
