hi @JakubVanko, thanks for the great tutorial. I have a question.

After registering my GCPs and re-align, i still get a large difference between the GCP coordinates and the Actual Position Coordinates (particularly in Z, that is around 5m). The alignment report however shows very small deviations (0.1m). This difference in altitude is also reflected when i export the model in OBJ, where the 3d Model is lower than what it should (by approximately 5m).

Appreciate your support on this.

Regards,

Hi OdysseasSeam,
what kind of images are you using? Have you tried to set the Prior pose of the images to Unknown and then georeference your data just using the GCPs?
