partial registration algorithm

Post by fblue »

Hello,
I'm on a project of doing registration on several point clouds which have one part in common for each. For example: as showed in the pictures, the first cloud has a cylinder and a cone; the second one has a cone and a sphere; the third one has a sphere and a box. The task is to register the three ones to one cloud which has a alignement of the shapes (cylinder, cone, sphere, box).

What kind of algorithms are often used or efficient in such case? I've tried ICP but the result is not so good.

I'm new in the domain of registration. So please give some key words or reference links and that could also help to guide me.
Thanks in advance!

Hum, not sure... To use ICP you would indeed have to roughly align the shapes and then set the 'overlap' parameter correctly.

But otherwise, I don't know...
