Example Sentences

By doing that, they proved that these animals have stereopsis—that is, their brains can work out how far away objects are by comparing the slightly divergent images perceived by each of their eyes.

Wardill and his colleague, Rachael Feord at Cambridge University, realised they could test whether cuttlefish use stereopsis by getting them to wear 3D glasses and playing them some juicy 3D shrimp movies.

Prof Jenny Read, a professor of vision science at Newcastle University, who last year discovered evidence for stereopsis in praying mantises, said the work proved there are different ways of achieving stereopsis: “Creatures like cuttlefish or mantises may seem outlandish, but understanding them will help us come up with varieties of machine vision which are most appropriate for different situations, say for a flying drone versus a robot vacuum cleaner versus a security camera. They are amazing examples of evolved engineering, and we have so much to learn from them.”

That process, known as stereopsis, computes distance by comparing how each eye sees objects in slightly different positions.

“The process of stereopsis has cropped up multiple times throughout evolution, but each time the neural circuitry and its capabilities are a little different.”
