Scientists from South Korea have developed a new computer vision system for robots and drones that imitates the unique features of a cat's eye. Systems with such vision are able to work both in bright daylight and in conditions of poor visibility, demonstrating better efficiency in recognition of objects compared to existing technologies.
Researchers from the Gwangju Institute of Science and Technology (GIST) have created a system that uses a slit aperture, similar to the vertical pupil of a cat, such a technical solution allows you to filter excessive lighting and focus on important objects.
In addition, the system is equipped with a special reflective layer that imitates tapetum — a special layer of the choroid of the eye, which improves visibility in the darkness.

It is worth emphasizing that traditional computer vision systems often fail in conditions with poor lighting.

«Standalone cameras usually have difficulty in detecting objects on filled or masked backgrounds, especially in changing lighting. The new system solves this problem by allowing robots to filter out unnecessary details and focus on meaningful objects», — scientists claim.
It is noted that "cat’computer vision" is energy efficient, as it is based on the optical design of the lens, and not on resource-intensive computer processing. Such technology will find application in various fields, from search and rescue operations to industrial monitoring.
