WebYou can use getOptimalNewCameraMatrix to compute the appropriate newCameraMatrix depending on your requirements. The camera matrix and the distortion parameters can be determined using calibrateCamera. If … WebJun 18, 2024 · Your choices are: You can keep it. This means that the warped image must have a larger area than the original one, so to show the "extra" field of view near the edges. But because there was more light at the corners than nearer to the side centers, you have to fill in the missing pixels with, say, black. The result is a warped image that has a ... kirkland organic chunky guacamole
