Hello everyone! I have been calibrated my camera using Matlab. After that, I use the calibrated parameter from Matlab to input in Camera calibration in Agisoft. When I align the photo, it gives me the inaccurate result. I notices that the Agisoft has the camera calibration function. Therefore, I conducted it. It gives me the acceptable result after finish alignment of photo. However, the result of calibration parameter is different. I want to know why it is different of calibration ? and how Agisoft determine the calibration parameter. My camera model is industrial camera IDS with 4mm focal length. Thank you very much.
