Automatic Life Jacket Detection For Drones 85
garymortimer writes "Sentient, an Australian company that makes drone software, has given UAVs the ability to search for small, high visibility objects such as life jackets. From the article: 'Kestrel Maritime is a software solution that processes electro-optical (EO) and infrared (IR) full motion video (FMV) from manned and unmanned vehicles (UAVs). The Life Jacket Detection enhances Kestrel Maritime EO capability to automatically detect small, high visibility objects whilst searching wide maritime areas.'"

I think a bigger point to this than that is that as the cost of UAVs comes down and the practicality of running them off solar power increases, that these would allow for significantly improved searches for people that are lost at sea. In much of the world, the reality is that this is probably going to be more useful for recovering bodies than for picking up people that are still kicking, but there will be exceptions. A person just does not last very long in 40 degree water.

I'd be surprised if in the next 20 years it doesn't become common for a cruise ship to have one or two of these just in case.
A good immersion suit [google.com] can keep you alive for several hours, at least. There are documented survival times of over 24 hours at around 40 degrees F.
Cruise ships are more likely to have UAVs designed to watch for terrorist / pirate activity rather than purely personnel rescue. I've heard of (but not seen) this being actively researched. Having a humanitarian aspect might make them more palatable.

It's already possible. A company makes an elongated RC blimp called the Hyperblimp that has already demonstrated solar-powered flight. These things are quite agile and have a decent payload - I think 6lbs has been done on the 30ft model, although I don't know what the solar panels themselves weigh.

It's news because in addition to detecting for objects such as life jackets, breakthroughs in analyzing software also has the ability to search for pairs of concentric circles located on anyone in a visible area, and prioritize them by size.

This can't be the first software of its kind... Five years ago, NASA was using much more subtle feature detection software in detecting interesting rocks and regions from satellite imagery of Mars. It seems like life jacket detection in oceans would be a much simpler reduction of that problem.
In WWII, they used pigeons to do this. Simply train them to pick a button when they see an orange spot somewhere. Then reward them with some food. I wonder how this compares to the software, in price and performance.

Accuracy isn't the only improvement drones could make. Speed is important too because obviously the faster you go the more area you can cover in a given time. Survival times in cold sea are not good so finding people quickly is vital to getting them out alive.
Higher altitude + more speed + better detection rates = more survivors, and the humans still get to be the heroes who pull people out of the water. Win-win?
