I think ICP (Iterative Closest Point) is typically used to compare two
point clouds if they are not too dissimilar.

Subject: [ros-users] How to compare two point clouds?
Hello everybody,
I have general question about 3D point cloud perception, since I am not
really familiar in processing point clouds. I would like to measure the
similarity of two point clouds ... a kind of fitness score between a
reference point cloud and another point cloud.
Currently I am checking the literature, however I couldn't find a
"basic" algorithm. The only common way I found, is the alignment of both
points clouds by their center of mass. Afterwards one of the point cloud
is rotated till a best fit is achieved with the other point could.
Is there maybe some other approach or technique?
Thanks for any comment.
Christian
