1. A method for an image-based visibility range estimation, comprising:
ascertaining a depiction of an object in an image, the image showing a depiction of surroundings of an image detection device; segmenting the depiction of the object in order to (i) obtain a first object range of the object having an equal first distance to the image detection device within a tolerance range, (ii) obtain a second object range of the object having an equal second distance to the image detection device within a tolerance range, (iii) determine a first object luminance for the first object range, and (iv) determine a second object luminance for the second object range; and determining an atmospheric extinction coefficient using the first object luminance, the second object luminance, the first distance, and the second distance, wherein the atmospheric extinction coefficient is in direct correlation to the visibility range. |
