Using sensors of a first and second sensor type first and second sensor data are detected and items of information describing identical objects and/or object attributes are allocated to one another in the first and second sensor data. The first and second sensor data are encumbered by first and second ambiguities. Values of the second encumbering ambiguities are at least as great as values of the first encumbering ambiguities. A comparison of the first and second encumbering ambiguities of items of information describing identical objects and/or object attributes takes place. In the case of values of substantially the same size, the items of information describing identical objects and/or object attributes are allocated to one another in the first and second sensor data. In the case of values which are not of substantially the same size the items of information describing identical objects and/or object attributes are confirmed or discarded.
