| 2013-11-01 08:40:09 -0600 | asked a question | Find point coordinate in a projected rectangle Hello OpenCV users. I'm in front of a thought-it-was-simple problem, and as I am quite rusty concerning geometry and mathematics, I would like to request your help. On the image below you can see a picture representing the problem This entire image represent the picture I get from my camera. In this image I suceed to detect 4 points (A,B,C,D), forming a rectangle. -I know the coordinates(in pixels) of these 4 points in my camera view. -I also know the real dimensions of the rectangle I'm trying to detect. Considering a point F in my camera view, I would like to calculate its coordinate in the frame formed by A,B,C,D. How to do this with openCV ? |
