  Real time, high resolution 3D reconstruction of scenes hidden from the direct
field of view is a challenging field of research with applications in real-life
situations related e.g. to surveillance, self-driving cars and rescue missions.
Most current techniques recover the 3D structure of a non-lineof-sight (NLOS)
static scene by detecting the return signal from the hidden object on a
scattering observation area. Here, we demonstrate the full colour retrieval of
the 3D shape of a hidden scene by coupling back-projection imaging algorithms
with the high-resolution time-of-flight information provided by a single-pixel
camera. By using a high effciency Single-Photon Avalanche Diode (SPAD)
detector, this technique provides the advantage of imaging with no mechanical
scanning parts, with acquisition times down to sub-seconds.
