Render a Image on a ArucoBoard with OpenCV + Python + OpenGL

My Goal is to render an Artpiece on top of a Aruco Board I am holding in my hand or lay on top of a Desk. You can find sample pictures attached. I have managed to do this using 4 markers. The issue is that the Webcam has to detect all 4 corners at once in order to render the image. What I am looking for: - Render webcam or video stream (OpenCV's VideoCapture) - Detect the ArucoBoard with in that webcam/video (OpenCV's ArucoBoard feature) - Render an Image that spans the entire ArucoBoard Here is the source code of someone who has already kind of done it using a single marker but my experience with OpenGL is limited to be able to do it myself: [login to view URL] If you have any questions I am happy to elaborate further. Thank you very much in advance.
