I am looking for a way to have the homography between the ground plane and the camera plane to warp the image from the camera in the bird eye view plan and reversely.\r\nI would like to know if I can have this homography directly or if it is possible to put a calibration pattern like a chessboard on the road ? \r\n\r\nThanks.
