Hi, I have an IR Image and I would like to register it with point cloud data. how would I do that using opencv ?

did you mean: making a pointcloud from your ir image, and then registering that to a 2nd point cloud ?

(please explain a bit more..)

yes thats what I mean. I have point cloud from depth image and I need to register it with the IR image onto a 2D plane

ah, sorry, misread it. i thought you had a depth, not an ir image.

Take a look at this paper. It doesn't rely on the color information, so there should be no difference for IR data. If that paper doesn't work for you, take a look at the references, search for it on google scholar and see who cites it, things like that.

@Tetragramm do you know if they provide somewhere the source code for this. I am trying to do something similar (register ir image to distorted rgb), though I am using simple homography extraction in order to obtain transformation matrices check here.
