I am busy working on my masters thesis which uses drones to track something down below using time lapse images. I.e. take the photo into AutoCAD and scale based on its height.
What i’m finding is that the Geo-tagged photos seem to drift around quite a bit, ±0.5m. I was wondering who else has a similar application and if there is any papers/case studies on the drone geotagging rather than taking the entire set and generating a photogrametric model (which i assume smooths out the error over all of the photos in the set to get a much better accuracy than the drone GPS).
