Automatic Life Jacket Detection For Drones 85

Posted by samzenpus from the eye-in-the-sky dept.
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.'"

  • 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.

      Well, unless NASA isn't telling us something, there's not a whole lot of ocean on Mars. Spotting a static object without a major time limit isn't exactly the same as having to spot a moving object in choppy seas before the person drowns or freezes, while keeping enough fuel to return to base. (Yes, I watch too much Deadliest Catch.)

      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.

      That's right I made a boob joke, go ahead and mod me down, it was worth it.

      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.

    Nice positioning. Search and rescue staff will still fly around in helicopters with mk1 eyeballs because they don't trust the drone. However, while trying to sell the image-recognition package as a bolt-on to a heli will fail due to pushback from observers, selling in a drone package will be considerably more palatable, psychologically.

      Search and Rescue also fly around with pigeons [susanscott.net] which are trained to peck at a button when they see life-jacket orange. They hit at a 90% rate compared to a human's 38%. Humans in helicopters? If your floating in the drink I think you'd be better off with a drone. Granted, a rescue chopper could pick you up as soon as they saw you, but at nearly a 2/3 chance of being missed?
    • Helicopters will full rescue crew are expensive to build and operate. I would imagine the best use of these drones would be to blanket the search grid. Instead of a handful of planes and helicopters doing lawnmower patterns over thousands of square miles of ocean, you could put a drone over every few dozen square miles. Use them to supplement the human search (or vice versa), and have the rescue helos check out any positive hits the drones report.

          Advanced technology is usually done for military purposes, not humanitarian ones.

  • High visibility is relative, in the IR band a speedboat full of pirates is high visibility. The military value of this could be huge. Regardless it looks like all coast guard and search and rescue ships will need to carry drones.

    • What about just having the drones based on land, flying around high-risk areas (possibly only when an alarm is raised), and when someone is found in the water, we send out a helicopter? I don't know about the economics, but my guess is that the drone fleet is reasonable enough in comparison to having a load of helicopters sent out each time a mayday is heard.

          I'd imagine a helicopter could get there pretty quick, as the drones have a limited operating range and are flying in a search pattern rather than a bee-line to the victim. OTOH, I wonder how well the small drones will operate in stormy weather, when most ships run into trouble...

          • Drones can be built to handle worse weather than a human pilot could. Drones don't have the squishy-body limitation on sudden accelerations. You could do things like kick in a rocket engine for 2 seconds and do a 20 gee ballistic exit from a death spiral, etc.

            Drones are cheap to fly. One vision of their use is to have the USCG maintain 24/7 patrols of the coast, with the drone on patrol and the rescue helicopter both dispatched to the scene when a mayday is received. The drone would usually arrive first a

You then have to search a potentially huge area to try and find them.

        Responding to mayday calls is never a matter of budget. It is always a matter of saving lives as quickly and safely as possible. While scrambling UAVs to search would be good to assist, you would still want to scramble a staffed rescue helicopter at the same time.

        • The response to an individual call may not be but the availiable resources are. At a high level someone will have to decide what resources to spend the money available for search and rescue on. Someone else will have to decide how best to deploy those resources to the calls that are coming in at any moment.

      • Seems like a fleet of drones operating from a ship would be one way of dealing with the Somali pirate problem. Drones are cheap enough to operate that 24/7 high altitude surveillance of the pirate coast is possible, with other surveillance drones dispatched as needed to track any potential pirate boats. Armed drones could intercept a possible pirate boat that was approaching another vessel, and could sink the damn thing if it began to fire on its victim.

    Hell, I bet the drone could even act as a WiFi hotspot or wireless repeater. You wouldn't get pulled out of the water right away, but you could sure as hell post all about it on Facebook.
