Now, for a new problem space: plant identification.
There are a few challenging plant groups to identify in the US. Among the ones I heard about in freshman biology: sedges (think: like grasses but with triangular stems and other distinguishing features), willows, and hawthorns (or Crataegus). A colleague of mine, John Reinier, has mastered the sedges to the point where I joke he can identify them in the dark with his eyes closed (where most people need a dichotomous key, 5 years of training, and a hand lens). He has started to botanize Crataegus, which require a season of observing flowers and fruit, collecting and carefully preparing the stones called pyrenes within them and observing their shape.
So, a question he asked was: can we photograph these and reconstruct them in OpenDroneMap? Then the 3D models we could send to experts to review and voucher without having to ship the actual pyrenes (or in advance of sending the physical vouchers).
Voila! It’s not a bad first pass. We will do some more testing, and maybe try scanning with a camera attached to a microscope as well.
