Sigh...
The M210 is *not* a 'consumer drone' - It's part of DJI's enterprise range and starts at just North of £7K.
Whilst this is a big improvement on the existing optical tracking algorithms, it's not exactly new. DJI have included Active Track in their actual consumer drones for around two years now. Unlike this algorithm, their version runs on a cheap processor running in the drone itself. Admittedly, it's easily fooled, but this shows that improvements are possible (and ultimately probably don't need ten grand's worth of equipment to run).
