‘Bat-sense’ tech generates images from sound – Phys.org

By cleverly analyzing the results, the algorithm can deduce the shape, size and layout of a room, as well as pick out in the presence of objects or people. The results are displayed as a video feed which turns the echo data into three-dimensional vision.
One key difference between the team’s achievement and the echolocation of bats is that bats have two ears to help them navigate, while the algorithm is tuned to work with data collected from a single point, like a microphone or a radio antenna.
