Greetings, I found the following comment regarding camera calibration that questions the accuracy and limited paramaters used in the Browns model:
"I should also say that Agisoft has fewer parameters in its lens model than does ADAMTech. For many applications this is fine, but for high-accuracy geomatics work it's crucial, in my opinion, to have all lens parameters activated and long floating point representations of the parameters (many programs appear to truncate the values)."
Is this true that the Browns model does not accurately model all of the needed lens distortion parameters if the appropriate floating point representations are used?
