Precision of laser data

[Moon light]

Hello everyone,

I have Two laser data from different sources
and i want to check the precision of these data using cloudcompare
Can you help me with the workfolw?
I tried to use the tool of (compute geometry feature) but I don’t think that I didn’t in the right way.

How do you define 'precision' here? Do you mean accuracy? And is one of the point cloud more accurate than the other maybe? (you could then compare the other one to this one, by computing distances between the 2 for instance). Or if you know some particular dimensions you can use either the Primitive fitting tools (sphere, cylinder, etc.) or Ground Control Points, etc.
