Résumé / Abstract
In this paper, we briefly present the LCPC and INRETS work on the modeling of the effects of fog on road vision. Thereafter, we show how we exploit these various effects to build estimators of the visibility distance. Thus, we present our measurement technique of the meteorological visibility distance exploiting the effect of atmospheric veil. This method Conists of a dynamic implementation of a model of light propagation in the atmosphere, which represents the variation of the luminance in the current image, according to the distance to the sensor. Then, we present part of our work on the exploitation of the effect of attenuation of contract by atmosphere.
