Abstract

A method is provided for determining a visual range in daytime fog, the method () including a step of reading in and a step of ascertaining. In the step of reading in, coordinates of at least one characteristic point of a brightness curve of a camera image of the fog are read in. The brightness curve represents brightness values of image points of the camera image along a reference axis of the camera image. In the step of ascertaining, a meteorological visual range in the camera image is ascertained using the coordinates, a meteorological contrast threshold, and a processing specification, in order to estimate the visual range in fog. The processing specification images location-dependent and/or direction-dependent scattered light through the fog in the camera image.
