When supplying cropped images the remapping to stereographic goes wrong, if the wrong/not correctly chosen lens parameters are given. This happens in your example: the first pto file supplies a hfov of 77 deg (or a focal length of 31 mm; and this for a 10-17 mm lens) and does not account for the cropping with d/e parameters. So cpfind is not able for correctly remap the images to stereographic and therefore the cp finding goes wrong. This is clearly a case of garbage in - garbage out. When using better lens parameters (like in your second pto file, correct hfov and take cropping into account), cpfind is able to detect 5 cp (ok, if finds 8 cp, 3 cp are disregarded by the RANSAC step, so 5 remains) So the log output for default parameters: --- Find matches --- i0 <> i1 : Find Matches... i0 <> i1 : Found 8 matches. i0 <> i1 : RANSAC Filtering with Panorama model... i0 <> i1 : Removed 3 matches. 5 remaining. i0 <> i1 : Too few matches ... removing all of them. i0 <> i1 : Clustering matches... If you want to keep these five cp, add --minmatches=3 to the command line and cpfind will add 5 cp to your project.
