visIvis – Evaluation of Vision based Visibility Measurement

PROBLEM STATEMENT AND RELATED WORK In air traffic management (ATM) and monitoring of critical infrastructure, the exact description of the atmospheric state - and thus the visibility - is an indispensable basis for any further weather forecast. In order to overcome the drawbacks of the currently subjective reports from human observers, we present ”visIvis”, an innovative solution to automatically derive visibility measures from standard cameras by a vision- based approach. Several research aims already target camera-based visibil- ity estimation. E.g. the weather services of the Netherlands (KNMI [3]) rely on a few manually selected landmarks with known distances to derive the prevailing visibility. A variety of approaches uses physics-based models to derive a visibil- ity measure (e.g. Koschmieder model or other measur
