I’m just a newbie in computer vision but I try to improve myself
I’m currently facing a problem and I don’t know how to deal with it.
I have a target picture that I want to project (homography) on a paper board containing aruco markers. (just something like what can be seen on this site https://learnopencv.com/augmented-reality-using-aruco-markers-in-opencv-c-python)
However I have a strong constraint that only allows me to have 2 markers instead of 4.
One of the marker is at the top left corner and the other one is somewhere between the 2 right corners of the ABCD frame I want to project to (see picture below)
What kind of operation should I use to get my 4 frame points in the camera preview from the markers ref points knowing that I of course know the distance between the markers and the points A, B, C, D on my sheet of paper?
Hope my question is clear …
Thanks in advance
