How to find corresponding points between target and source point clouds? #58

Closed mirickmi closed 2 years ago

mirickmi commented 2 years ago

Hi,

is there a way to access a matrix with indices that tells me which point from the target corresponds to which point from the source?

I wouldn’t usually use it that way. Instead, i would usually use one point cloud as the template and then wherever the points land on the target after registration those are the new points for the target. This guarantees one-to-one point correspondences. And If you want to register many point clouds together they all have this perfect correspondence to the one template.
