Hi, I'm doing my first steps in lens calibration. Currently I'm trying to get distortion correction data from Hugin.
What I've noticed is that working with different images I get different values for a, b, c. As Hugin seems to average all values for individual focus lengths (???) I did not keep track of the values, only noticed the change. Example values: a; b;c; computed using 4 images: 0,032214; -0,105173; 0,069074 computed using only one of the images: 0,031828; -0,100712; 0,058477 Is this normal or an indication of bad images used for calibration? Is there a simple way to test (aka see in action) the computed values? I tried it through Gimp + GimpLensfun, but my entry ./local/share/lensfun/test.xml doesn't get included in the lens list. The file itself gets loaded - I get an error message, when it contains garbage (but only if before <lensdatabase>). TIA, Oliver ------------------------------------------------------------------------------ _______________________________________________ Lensfun-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/lensfun-users
