UAVs create 3D model of the Matterhorn
eBee drones from Sensefly, which are equipped with a 16 MPixel camera and Postflight Terra 3D-EB mapping software, were used to autonomously create a 3D model of the Matterhorn Mountain.
Sensefly, the creator of the lightweight, vision-enabled eBee unmanned aerial vehicle (UAV), or drone, has teamed up with Drone Adventures—a non-profit company which promotes the potential use of drones in drones in civilian applications—to autonomously map the entire Matterhorn Mountain.
eBee drones have a 37.8 inch (96cm) wingspan and weight less than 1.5 lbs. (0.7kg ). The foam airframe drones are equipped with a rear-mounted propeller and feature a 16 MPixel camera which is electronically integrated and controlled. eBees can travel in the air for more than 45 minutes and feature USB connectivity for interfacing with the camera and on-board autopilot. The UAVs also come with Postflight Terra 3D-EB mapping software that runs off a desktop computer or laptop and processes aerial imagery into 2D maps and 3D models.
In order to map the 14,692 ft. (4,478 m) mountain, which is on the border between Switzerland and Italy, members from Drone Adventures scaled the mountain and hand-launched one drone from the top. Five other UAVs took care of mapping the lower parts of the mountain, according to IEEE Spectrum.
By setting an outline of a map on Google maps prior to launch, flight planning software enables the eBees to do their own 3D flight planning, even taking into account any mountains or obstacles that may come into play. Up to 10 drones can be used and controlled from a single base station during one mission. Each one of them will autonomously avoid airborne collisions, even going as far as to coordinate individual landing times.
