Method and device for tracking-based visibility range estimation

A device for a tracking-based visibility range estimation, comprising:

• an arrangement for tracking an object depicted in a first image detected at a first point in time and in at least one second image detected at a second point in time;
• an arrangement for ascertaining a first object luminance of the object and a first distance to the object at the first point in time;
• an arrangement for ascertaining a second object luminance of the object and a second distance to the object at the second point in time;
• and
• an arrangement for determining an atmospheric extinction coefficient using the first object luminance, the second object luminance, the first distance, and the second distance, the atmospheric extinction coefficient being in direct correlation to a visibility range.

A computer program which is designed to carry out a method for a tracking-based visibility range estimation, comprising:

• tracking an object depicted in a first image detected at a first point in time and in at least one second image detected at a second point in time;
• ascertaining a first object luminance of the object and a first distance to the object at the first point in time;
• ascertaining a second object luminance of the object and a second distance to the object at the second point in time;
• and
• determining an atmospheric extinction coefficient using the first object luminance, the second object luminance, the first distance, and the second distance, the atmospheric extinction coefficient being in direct correlation to a visibility range.
