Claim 11:
12. The method according to claim 1, wherein the method further comprises at least one empty-calibration step, wherein in the at least one empty-calibration step dimensions of an empty storage unit are determined, wherein the at least one empty-calibration step comprises:
i) illuminating the empty storage unit with the at least one illumination pattern comprising the plurality of illumination features and determining the at least one reflection image of the empty storage unit;
ii) selecting the at least one first reflection feature and the at least one second reflection feature of the reflection image;
iii) for the first reflection feature, generating the at least two first sensor signals in response to an illumination of the at least one sensor element by the first reflection feature, and for the second reflection feature, generating the at least two second sensor signals in response to an illumination of the sensor element by the second reflection feature;
iv) evaluating the two first sensor signals generated in step iii) thereby, determining the at least one first longitudinal coordinate of the first reflection feature, and evaluating the two second sensor signals generated in step iii), thereby, determining the at least one second longitudinal coordinate of the second reflection feature, wherein the evaluating comprises evaluating the first combined signal from the at least two first sensor signals and the second combined signal from the at least two second sensor signals;
v) determining the at least one position of the first reflection feature and the at least one position of the second reflection feature in the reflection image and determining the at least one first vector of the first reflection feature and the at least one second vector of the second reflection feature; and
vi) determining from the first vector and the second vector the at least one elevation map and determining therefrom dimensions of the empty storage unit.
