Numerical and experimental evaluation of road infrastructure perception in fog and/or night conditions using infrared and photometric vision systems

摘要

Use of infrared vision in automotive industry has mainly focused on detection of pedestrians or animals at night or under poor weather conditions. In those approaches, the road infrastructure behavior in infrared range has not been investigated. So, research work was realized using numerical simulations associated with specific experiments in a fog tunnel. The present paper deals with numerical simulations developed for both visible spectrum (visibility in fog) and infrared vision applied to road infrastructure perception in foggy night conditions. Results obtained as a function of fog nature (radiation or advection) are presented and discussed.
