Title: Camera precalibration
Post by: AVisser on August 17, 2015, 05:22:45 PM
I recently did a survey using a precalibrated camera. When processing in Photoscan, however, when I fix the calibration under Tools->Camera calibration the results are way worse than when I do not fix the calibration. The difference in error is about one order of magnitude.
I suspect this is because if you fix the calibration Photoscan has less degrees of freedom moving things around to obtain a proper fit. Thus, is it better to precalibrate and get large errors, or do not precalibrate and basically do not know what changed?

Did you ever get any response from this question AVisser? I have just started using agisoft and have the same concern.
