Abstract:
1. A method for determining a number of floors of a building based on image data of the building, the method comprising the steps of: determining by a processing unit a background color of a façade of the building shown in the image data; detecting by the processing unit predefined deviations from the background color in the façade of the building; determining by the processing unit a mean number of predefined deviations in a vertical direction of the façade of the building based on the detected predefined deviations; and deducing by the processing unit the number of floors of the building based on the determined mean number of predefined deviations, wherein the number of floors corresponds to the determined mean number; wherein the predefined deviations are determined by dividing the façade of the building in a plurality of vertical sections, wherein the predefined deviations from the background color are determined for each vertical section, wherein a mean number of predefined deviations may be determined based on the predefined deviations determined for the vertical sections.
