Giving cops helicopters led to constant overflights in populated areas like L.A. and NYC. I don't feel like I'm under constant surveillance.That's because you're not. But the police would be able to fly hundreds of these for the same price, with no pilots needed.
Unless there is some odd definition of loitering that I don't know about that does not mean 'hovering in one place about 400 feet up for 20 minutes'.Try 14 hours, which is what a Predator can do.
Over recent years, much research has taken place in the fields of dismount detection and tracking in terms of persistent surveillance in general with success limited to simple perimeter intrusion detection or variations from learned, regular pedestrian traffic patterns. Even more intractable is the problem of detecting single dismounts in urban environments, associative tracking of individual dismounts, and analysis to determine dismount activity in data from multiple sensors. Success is needed in associative tracking of dismounts in urban environments and determination of patterns of adversarial intent once effective tracking has been established. The innovation here over previous work is the ability to not only perform associative tracking of individual dismounts in urban environments (meaning many dismounts going about their normal routines) but also to track long enough to recognize adversarial intent.They want to be able to nearly continuously track people as they get in to and out of vehicles, enter and leave shops and homes, etc. They were talking about using a 25 gigapixel camera for this, which means a handful of loitering UAVs could potentially cover an entire city the size of Los Angeles.
