Abstract
We propose a novel passive procedure to estimate the 3D location of non-line-of-sight objects by measuring the light field of scattered long-wavelength infrared radiation. By scanning an infrared camera in a horizontal plane, the scattered light is collected as a light field cube. We introduce mathematics that separate the weak information-bearing signal in the light field cube from residual scattered light and utilize this information to determine highly precise object locations. Finally, we experimentally demonstrate the 3D localization procedure in a life-sized hallway consisting of diffusive walls using human-temperature non-line-of-sight objects.
