Finding correspondences

nenadpol
This post was updated on .
Hi,

This is task description:

I have two clouds, source (with n_s number of points, about 1000 points) and target (with n_t
number of points, about 1000 points).

Source and target have nr common points , where nr is >3 but nr is low
number  ca 5-10 points.

What would be best approach to find nr points, in other words,
correspondeces between two clouds?

It is important to say that between two clouds exists significant rotation
about all three axis and translation, in other words, position of two clouds
are totaly different.

Appriciate any help

thaks
Nenad

Re: Finding correspondences

Sérgio Agostinho
My naive approach would be tackle the problem as a registration problem
first (with unknown correspondences) and then extract correspondences at
the end.

So first step explore everything in the registration module.

Cheers
