Hi!

&nbsp;

I would like to ask you for information about georeferencing.  
With pix4d I was able to reconstruct an orthophoto, but when I apply georeferencing to the project the resulting orthophoto is distorted.

How is it possible?  
Am I doing something wrong?

Waiting for your answer.

&nbsp;

Best regards.

Hi Federica,

&nbsp;

Could you please post here&nbsp;the&nbsp;quality report of your project and some screenshot of the&nbsp;distorted&nbsp;orthomosaic so we can better understand in the issue?&nbsp;

&nbsp;

By georeferencing are you referring to adding GCPs?

&nbsp;

Thanks,

Ina
