I'm trying to deskew an image that contains an element of known size. Here's a test image:
I can use
aruco::estimatePoseBoard which returns rotation and translation vectors. Is there a way to use that information to deskew everything that's in the same plane as the marker board? (Presumably by using the rotation and translation vectors to create a transformation matrix to pass to
I know how to deskew the marker board itself. What I want to be able to do is deskew the other things (in this case, the cloud-shaped object) that are in the same plane as the marker board. I'm trying to determine whether or not that's possible and, if so, how to do it.
I can already put four individual markers around the object I want to deskew and use the detected corners along with the known distance between them as input to
getPerspectiveTransform. That works very well. But for our real-world application it may be difficult for the user to place markers exactly. It would be much easier if they could place a single marker board in the frame and have the software deskew the other objects.
