Hi Alexey,

thanks for your reply.

My aim is to compare the MetaShape calibration and the external calibration.

I have done the calibration in MetaShape using the same dataset and found that the K parameters show too much correlation. Additionally, the external software can only determine K1-3. Therefore, I have decided to omit K4 altogether.

I understand that MetaShape approximates the K1-4 parameters on import. Does that mean the conversion is not done by a straight forward equation? I was assuming the conversion just calculates pixel values from the mm values. As mentioned above, my parameters are generated in VMS (not Australis).

Can you provide conversion equations? I could calculate my own values and feed them directly into the camera calibration window without using the conversion tool.

Thank you,

Johannes
