An optical flow-based learning process developed by researchers at the Netherlands' Delft University of Technology (TU Delft) and Germany's Westphalian University of Applied Sciences lets robots calculate distances through the visual appearance of objects in view.

This approach boosts the navigation skills of small aerial drones by mimicking flying insects' intelligence.

TU Delft's Guido de Croon said enabling robots to interpret optical flow, as well as the visual appearance of objects in their environment, would eliminate certain limitations to optical flow.

The solution involved the drones inducing optical flow oscillations to perceive distances to objects in the scene via visual cues.

Westphalian's Tobias Seidl said, "The presented learning process forms a novel hypothesis on how flying insects improve their navigational skills, such as landing, over their lifetime."
