Application of a vision model in a nocturnal fog by videophotometric image analysis

Driving in poor meteorological conditions is particularly dangerous in terms of road safety. In order to investigate the visibility thresholds of targets in these conditions, experiments were conducted in a fog chamber. A new method using a Calibrated camera, in comparison to traditional photometers, was investigated in order to measure the complete visual field using a luminance matrix. The luminance map can subsequently be analysed in order to determine significant parameters for the visibility of the analysed objects. In addition to metrological aspects, the experiment data were analysed and compared to a theoretical approach using a Vision Model developed by Adrian.
