Title: Difference in the final error with LOW and HIGH alignment parameters
Post by: tuffi on September 13, 2018, 10:52:11 AM

Hi,
I performed the aligment of one images dataset. Every images have camera position acquired with RTK GPS (with better than 5 cm accuracy in the 98.5% of photograms).

After the align phase with LOW parametres I obtained a total main error of about 7 cm.
The same dataset processing with HIGH parameters give me a error of 53 cm.

In attachment a screenshot of the report.

It's normal? I had about 70 GCP to put on the model...wich models is better?

Thank you...

Hello tuffi,
Have you performed the optimization of the camera alignment? Also have you checked the errors on validation points placing them after the alignment and optimization are finished?
