Hi,
Recently I got bunch of images from x amount of different cameras(GoPro, handheld and drone). I managed to get decent model. Only drone images had gps data (M300 and M3E), not sure how accurate. I get no GCPs and there is no way to verify accuracy, but looking at the RC map it all looks fine.
Registration and Georeferencing accuracy report showed me this for 28 images.
What exactly does it means and how that relates to other images and accuracy of the 3d model?
The values in the last columns are deviations of the calculated coordinates that you get from the alignment from the initial imported coordinates. So if the initial coordinate value is 500.5, and the calculated is 500.2, the deviation will be 0.3.
The accuracy of the GPS measurement has to be taken into account too. If your GPS setup gets 0.05m accuracy, then any deviation above that will be considered inaccurate—just as you can see in your values. This inaccuracy doesn’t have to be visible on the model since there are other factors taken into consideration during the alignment (intrinsic parameters, distortion, etc.), and the report is used to showcase the georeferencing information.
Great explanation @kumateCR . Thanks
