Artificial Compound Eye Improves 3D Object Tracking

Flies are fast-reacting creatures and can sense movement quickly. Researchers have now used flies as their inspiration by developing an aThe development can be used with a camera for applications like the creation of 3D location systems for robots, self-driving cars and unmanned aerial vehicles. "Imitating the vision system of insects has led us to believe that they might detect the trajectory of an object based on the light intensity coming from that object rather than using precise images like human vision," said Le Song, a member of the research team from Tianjin University in China. "This motion-detection method requires less information, allowing the insect to quickly react to a threat." [snip]


"This uniform light receiving ability of our bio-inspired compound eye is more similar to biological compound eyes and better imitates the biological mechanism than previous attempts at replicating a compound eye," explained Song.rtificial insect inspired compound eye that can sense a moving object and its trajectory with an astonishing speed.
