Autel Evo Max 4t GCP Error


I recently purchased an Autel Evo Max 4T aircraft, acquired 3000 images, and am post-processing them using Pix4d Mapper.

21 GCP points and 8 checkpoint points were applied, and initial processing and re-optimization were repeated.

The reason for repeating is that GCP errors occur in XYZ from as little as 50cm to 1m.

Because anti-aircraft markings were used, marking errors could not occur, and there were no problems at all in the process of acquiring GCP value data.

Are there any cases of this kind of error occurring during the optical image processing of Autel Evo Max 4T?

It hasn’t been resolved for several days.

Please help…

Thank you.
