Abstract

In almost every practical scenario the light reflected from a surface is scattered in the atmosphere before it reaches a sensor. While this effect can be a little annoying for the amateur photograph trying to take a picture, it can have disastrous consequences for unmanned autonomous vehicle navigating through fog for instance.

By employing an innovative method based on a clever combination of spectral bands and polarization analysis, coupled with advanced image processing techniques, significant improvements have been achieved on fog obscurant using the existing passive full Stokes polarization imaging camera for visible light “SALSA” (developed by Bossa Nova Technologies).
