Method and assistance apparatus for supporting vehicle functions in a parking lot, and motor vehicle

The disclosure relates to a method and an assistance apparatus for supporting vehicle functions in a parking lot. Surroundings data are recorded and processed in order to recognize semantic and/or geometric objects, wherein the surroundings data depict the parking lot or represent same in the form of a point cloud. Data portions are extracted from the surroundings data, these data portions corresponding to semantic and/or geometric objects that have been classified as relevant to a parking maneuver and comprising pixels or data points that depict or represent the recognized semantic and/or geometric objects. Of the surroundings data, only the extracted data portions together with object data that, as a semantic and/or geometric attribution of the data portions, in each case indicate to which at least one semantic and/or geometric object the data portions correspond, are then sent to a server in order to automatically create an overall map.
