A revolutionary technology now makes it possible to see through barriers, revealing what lies behind walls, doors, or cars in 3D using just a single photograph.

The technology works by analyzing shadows with an algorithm and then constructing accurate, full-color 3D models of spaces out of view. Its potential applications could include preventing car accidents, aiding law enforcement, and enhancing military strategies.

The research is the first to achieve such a feat using an ordinary digital camera. Previous attempts required expensive and specialized equipment or produced low-quality 2D reconstructions.

Researcher: “We’re turning ordinary surfaces into mirrors to reveal regions, objects, and rooms that are outside our line of vision. We live in a 3D world, so obtaining a more complete 3D picture of a scenario can be critical in several situations and applications.”
