I use this code run on iPad ,but the result only is background frame,the three-dimensional coordinates and Quadrilateral don't have on screen. I use the code CameraCalibration(2.4656738184245560e+003, 2.4696085211324871e+003, 1.3580461718453680e+003, 1.0434397075976763e+003) run on iPad
2 ,but also don't appear he three-dimensional coordinates and Quadrilateral,why?
