I recently installed a 3.97mm lens on my GoPro. Unfortunately, the results with this new, supposedly “distortion free” lens are even worse than with the stock GoPro lens.
The fisheye GoPro images typically produced a severely “bowed” model in RealityCapture unless using “division” alignment and “high” detector sensitivity, and even then the results didn’t look as accurate as the same photos processed in Photo-Scan with the fisheye parameters or with calibration specific to the GoPro.

The subject of the photographs is a flat beach and coastline. The same photos aligned without issue in other photogrammetry software tests, are there some settings I can tweak in RC to get it working?
