altizure (dose that work with phantom 3?) might be a go.
i think angled gimbal shots will work better than straight down.
you will also want to change heights. don’t do everything at the same altitude.
I haven’t really had time to do too much experimenting with shooting patterns with uav. but I’m interested in solutions for setting up flights paths, so feel free to let me know once you have found a good one.
jarrad,
for the alignment to work well you need to see the same object in the start and end of a loop of photos. this seems to work best if they are smaller areas, and more of them. rather than big long sequence before you see the start again.
also you will need to experiment with some alignment settings like, image overlap, max feature per image, detector sensitivity.
