Twelve 90fps VGA cameras pointing in every direction are used to guide the drone to it's target - hovering above the free floating target drone. Rapere says that detecting a free floating object which is well illuminated and far from any other visible object is easy. The counter-drone can burn lots of watts on the onboard computer, because of the short intercept flight time, which also simplifies the work.
With drones and anti-drones both using many cameras, it appears that image sensor market is set for a new explosive growth.
