Drone tracks vanished forest walkers – New Technology

       

The Swiss and Italian researchers have developed a software that enables the drone to navigate ground in the woods and seek out persons reported as missing after an excursion in the woods or in the mountains. Only in Switzerland, rescue thousand alarms per year for bad or misguided forest walkers.

The drone could easily and cheaply be able to assist the search party chains that are being put into the search for people who strayed into the deep forests, and thus shorten the search time and increase the chances for an injured person to get treatment in time.

Researchers at the Dalle Moll Institute for AI and the University of Zurich has developed AI software to learn a little quadro Copts to independently find and follow the trail in the forest.

the drone flying autonomously at higher elevations are already commercially available, but it is much more difficult to develop drones who make their way in complex environments like dense forest, where minimum navigation error knocks out the craft.

the Swiss drones equipped with some small cameras, similar to those found in cell phones. In sets of advanced sensors using drones powerful AI algorithms to interpret the images taken and identify a track, and know then follow this track.

Such a task can be difficult for a human tracker. Researchers use neural networks where the drone computer learns to solve problems on the basis of training examples. To learn drones devoted scientists long periods spent looking track in the Alps and took over 20,000 pictures with cameras mounted on their helmets.

The result was successful: When drones were tested following the traces of the past in followed so found neural network right direction in 85 percent of cases, compared with people who got the same task and guessed right 82 percent of the time.

Although much practical work remains before a swarm of drones go out into the woods to look for missing people so scientists are still convinced of the usefulness of these small craft artificial flying sniffer dogs.

Professor Davide Scaramuzza at the University of Zurich says that now that drönar has learned to find and follow the trail in the woods so scientists must teach them to detect people.
