By sensing tiny changes in shadows, a new system identifies approaching objects that may cause a collision.

Massachusetts Institute of Technology engineers have created a system that captures tiny fluctuations in ground shadows to ascertain whether an unseen object is coming around a corner.

Massachusetts Institute of Technology (MIT) engineers have created a system that captures tiny fluctuations in ground shadows to ascertain whether an unseen object is coming around a corner.

MIT's Daniela Rus said, "The big dream is to provide 'X-ray vision' of sorts to vehicles moving fast on the streets."

The ShadowCam system employs computer vision to detect and categorize changes to such shadows.

The system receives sequences of video frames from a camera focused on a specific area, and identifies changes in light intensity over time, image to image, that may signal something approaching or moving away; ShadowCam classifies each image as containing a stationary or moving object, and reacts accordingly.
