Partial Overlap Reference

[SmirkyMcFace]

Hello,

First of all, I have been using CC for my study and this software is super useful. I just want to say thank you to anyone who has contributed to this. Thank you so much!

I am trying to understand more about the theory/mechanics behind the "final overlap" function in the registrations. They worked well for my applications but I don't understand why. I found something called "Trimmed ICP" but I am not sure if it is the same thing. Is the "final overlap function" based on some journal articles? Or is there any resources that someone can kindly share with me?

Thank you again!

We haven't developed it following any article at least. But in a way it's a subcase of 'trimmed ICP' I guess.

We simply ignore the X% of points that are farther from the reference entity at each iteration (where X = 100 - overlap%).

Ah ok, thank you for the clarification.

Then can you please point me to the section of GitHub where I can look at the exact algorithm you used to implement the partial overlap ICP?

Thank you again!
