Quick background: I’ve been experimenting with AutoGCP. The first time using it (2/25/2021) I flew a grid with 70° camera angle, but then read shots should be nadir, but it worked. I’m using Aeropoints, and had no issue using that state plane coordinate data imported during the data set import (pretty intuitive). The orthomosaic GCPs and their locations lined up perfectly.
I flew with Mission yesterday, good conditions and connectivity the whole time. This time flew a grid, 80/80, normal+, sunny, 200’ agl. First indication of issue was that only 2 of my 6 GCPs were found (and not many photos of each). I then noticed on the quality report the uncertainty ellipses were nothing like I’d seen before! While the orthomosaic looks good enough for its purpose, none of the GCPs aligned. I assume this was because of the uncertainty.
Looking through the quality control help, I’m trying to determine if moving construction traffic was to blame, or what exactly I should be chasing after (flying during less traffic, more GCPs, etc). Any help or input is appreciated.
