‘Spectacular’ finding: New 3D vision discovered in praying mantis

Miniature glasses have revealed a new form of 3D vision in praying mantises that could lead to simpler visual processing for robots. Publishing their latest research in Current Biology, the Newcastle University team have discovered that mantis 3D vision works differently from all previously known forms of biological 3D vision. 3D or stereo vision helps us work out the distances to the things we see. Each of our eyes sees a slightly different view of the world. Our brains merge these two views to create a single image, while using the differences between the two views to work out how far away things are.
