METHOD AND DEVICE FOR TRACKING-BASED VISIBILITY RANGE ESTIMATION |
| 摘要 |
A method is provided for tracking-based visibility range estimation for a vehicle, the method including a step of tracking an object detected in a first image at a first point in time and in a second image at a second point in time, a step of ascertaining a first object luminance of the object and a first distance to the object at the first point in time and also ascertaining a second object luminance of the object and a second distance to the object at the second point in time, and also a step of 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 visibility range. |

1. 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. |
