Hi Robert, I would try deleting control points that are not near the likely seam position. This seems counter intuitive, but these pixels will not end up in your final image.
Important, if you do this the optimiser can find all sorts of crazy solutions for the a, b & c lens distortion parameters. To prevent this you need to either: only optimise angle of view, or create lots of vertical control points to properly calibrate the lens distortion (I would create the vertical points). I would also delete any close control points, ie. The floor might look like a great calibration source, but using it will amplify any parallax problems caused by the slight offset between lenses. Also, these circular fisheye images are very unlikely to be central in the frame, so you need to optimise d & e parameters separately for each side. -- Bruno On Sat, 22 Nov 2025, 22:37 Robert Grübler wrote: > My workflow “poor man's street view” with the Samsung Gear 360 (2017) > works quite well, the only annoying thing is the sometimes noticeable > breaks in building lines.
