The biggest issue in real life use cases is lens distortion - these alignment algorithms usually don't correct barrel, pin-cushion or more complex lens distortions, making the alignment imperfect.
- nullc 5y agoAny of the standard panorama software can solve for a standard simple lens distortion model, it just needs a few more alignment points to do so.
- zwieback 5y agoOpenCV, which is what the OP is using, has higher order camera calibration. There are functions to calibrate based on checkerboards or dot grids and undistort images using those calibrations. Sometimes it's better to match first, then undistort, though.
