In the dark, bats "see" using echolocation or sonar. Their high-frequency squeak is reflected from
The bulging, compound eyes of flies give them a nearly 360-degree field of view, despite the fact that their eyes have a fixed focal length. This makes it difficult for them to see objects from afar.
Inspired by the arrangement of flies and bats,The team developed the CLIP system, a high-performance 3D camera with advanced features. During experiments, the researchers showed that the system "sees" hidden objects that are not detected by conventional 3D cameras.
The camera also uses lidar technologymeasuring distance with a laser. It scans the surroundings to create a 3D map of the area. The researchers showed how a camera system can show a complex 3D scene with multiple objects at different distances.
"If you close one eye and look atmug behind your laptop, you may not see it because the laptop blocks the view,” explained Liang Gao, one of the authors of the development. - But if you look with both eyes, the view will be better. This is how our system works, but we use compound insect eyes.”
Gao says CLIP helps camera arraysimilarly understand what is hidden. Combined with lidar, the system is able to achieve the effect of bat echolocation: a hidden object can be detected by how long it takes for light to reflect back into the camera.
