The Washington Post reported last week that the U.S. government is in talks with Facebook, Google and other tech companies about using anonymous location data to combat the coronavirus, including tracking whether people are keeping at safe distances from one another.

Their technique uses single-photon detectors combined with a unique computational imaging algorithm that achieves super-high-resolution images by knitting together the sparsest of data points. The big advantage of this kind of active imaging is that the photons reflected from the subject return to the detector within a specific time window that depends on the distance.

But even while the gating and infrared lasers greatly increase the density of captured photons and reduce the noise in comparison to other methods, the amount of points captured by the camera is still too low to generate a detailed image on their own.

Desktop applications designed to do so are publicly available online, and give anyone access to a virtual map, on which you can travel from place to place, from city to city, and from country to country, while seeing the exact location of cruising men that share their distance online.
