Abstract
A method for detection or the density determination or the classification of an aerosol using spectroscopy includes: using an image taken by a camera for a vehicle, a first value of a parameter being ascertained from the at least one image in a first step, using a first color filtering, and a second value for the same parameter being ascertained in a second step having a second color filtering, which is different from the preceding color filtering, and the values ascertained in the at least two steps are compared, and as a function of the result of the comparison, the detection or the density determination or the classification of the aerosol is carried out.

14. A method for performing one of detection, density determination, or classification of an aerosol in an environment using at least one image of the environment taken by a camera of a vehicle, comprising:
-
in a first step, ascertaining a first value of a selected parameter of the at least one image using a first color filtering; in a second step, ascertaining a second value of the selected parameter one of;
(i) without the first color filtering, or (ii) using a second color filtering different from the first color filtering;comparing the ascertained first and second values; and performing, as a function of the result of the comparison, the one of detection, density determination, or classification of the aerosol. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A device for performing one of detection, density determination, or classification of an aerosol in an environment using at least one image of the environment taken by a camera of a vehicle, comprising:
-
a parameter determination unit having at least a first color filter and a second color filter different from the first color filter, wherein the parameter determination unit is configured to; ascertain, in a first step, a first value of a selected parameter of the at least one image using a first color filtering; and ascertain, in a second step, a second value of the selected parameter one of; (i) without using the first color filter, or (ii) using the second color filter; and a comparator configured to compare the ascertained first and second values, and perform the one of detection, density determination, or classification of the aerosol as a function of the result of the comparison.
