Event Camera Helps Drone Dodge Thrown Objects
Watch this drone not get hit by a soccer ball
Davide Scaramuzza’s Robotics and Perception Group at the University of Zurich pioneered the use of event cameras on drones. We first wrote about event cameras back in 2014: These are sensors that are not good at interpreting a scene visually like a regular camera, but they’re extremely sensitive to motion, responding to changes in a scene on a per-pixel basis in microseconds. A regular camera that detects motion by comparing one frame with another takes milliseconds to do the same thing, which might not seem like much, but for a fast-moving drone it could easily be the difference between crashing into something and avoiding it successfully.
In a paper recently accepted to IEEE Robotics and Automation Letters, Davide Falanga and Suseong Kim from Scaramuzza’s group take a look at exactly how much of a difference it can make to use an event camera on drones moving at high speeds. And to validate their research, they hurl soccer balls at a drone as hard as they can, and see if it can dodge them.
