Measuring rain droplets with an Event Camera paper published
Measuring rain droplets with an Event Camera paper published
How do you measure rainfall droplet size distributions? It turns out to be necessary to know the size and speed distribution to infer the volume of water and the erosion effect. Our collaboration with Dr. Joerg Rieckermann at the Swiss Federal Institute of Aquatic Science and Technology (EAWAG) has just appeared in Atmospheric Measurement Techniques.
"Measuring diameters and velocities of artificial raindrops with a neuromorphic event camera" reports a novel rain droplet measurement method that uses a neuromorphic event camera to measure droplet sizes and speeds as they fall through a shallow plane of focus. Experimental results report accuracy similar to a commercial laser sheet disdrometer. Because these measurements are driven by event camera activity, this approach could enable the economical deployment of ubiquitous networks of solar-powered disdrometers. Check out the DVS Disdrometer paper website.
