- defrost 9mo agoNot bad, but practically have you seen the underside of many trains? The spit up of grease, leaves, metal particulate from rail and wheel grind, etc gets pretty thick. The vision challenge is to cheaply and effectively keep a clean lens. There's a similar challenge in monitoring production conveyor belts in mineral processing - vibration, tempreture, rocks kick about, dust make for a savage environment.
