Amid the continued spread of coronavirus, extra care is being taken by just about everyone to wash hands and wipe down surfaces, from countertops to groceries. To spotlight potentially contaminated surfaces, hobbyist Nick Bild has come up with Deep Clean, a stereo camera system that flags objects that have been touched in a room. The device can be used by cleaning crews at hospitals and assisted living facilities or anyone who'd like to know what areas need special attention when trying to prevent disease transmission. Deep Clean uses an NVIDIA Jetson AGX Xavier developer kit as the main processing unit to map out a room, detecting where different objects lie within it. Jetson helps pinpoint the exact location (x,y-coordinates) and depth (z-coordinate) of each object.
