摘要：
Described herein is a method for determining a filling level in at least one storage unit. The method includes
illuminating the storage unit with at least one illumination pattern;
selecting at least one first reflection feature and at least one second reflection feature;
for the first reflection feature, generating at least two first sensor signals, and for the second reflection feature, generating at least two second sensor signals;
evaluating the two first sensor signals and the two second sensor signals;
determining at least one position of the first reflection feature and at least one position of the second reflection feature and determining at least one first vector of the first reflection feature and at least one second vector of the second reflection feature; and
determining from the first vector and the second vector at least one elevation map and determining therefrom the filling level in the storage unit.
