ABSTRACT:
To determine the visual range of, in particular, a driver in a motor vehicle, a contrast ((c(x1), c(x2)) is measured from at least two measuring positions (x1, x2) of a measuring device situated at different distances from the object, and the ratio of the measured contrast values is converted to a visual range (δ), using the difference of the distances of the measuring positions from the object.
