A Camera That Sees Around Corners Could Help Improve Self-Driving Cars
“Many of today’s self-driving cars use automated systems that work in tandem with a collection of sensors and cameras. For example, Tesla’s Autopilot relies on radar and other sensors as well as a suite of eight cameras. However, none of these cameras can tell the driverless car what’s around a corner — an ability that researchers from the Massachusetts Institute of Technology (MIT) have developed with a new camera system they call CornerCameras.
In a study published online, these researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) described the algorithm behind CornerCameras. Where regular vision, whether it be biological or mechanical, relies on light, CornerCameras captures subtle changes in lighting. Specifically, they spot what the researchers called “penumbra” — a shadow created by a small amount of light that’s reflected on the ground directly at the camera’s line of sight from objects obscured around a corner…”
