According to a method for operating a sensor system, radiation is emitted during a first and a second measurement time period in order to generate point clouds, the points of which are described by a spatial position and an energy characteristic. A first sub-quantity of a first point cloud and a second sub-quantity of a second point cloud are identified with an energy characteristic which is greater than or equal to an energy threshold in each case. A third sub-quantity of the first point cloud and a fourth sub-quantity of the second point cloud are identified with positions lying within the spatial surroundings of the first sub-quantity and the second sub-quantity, respectively. The spatial extension of the fourth sub-quantity is compared with that of the third sub-quantity, and the points of the third and/or the fourth sub-quantity are marked as artifacts based on the result of the comparison.

Active sensor system and object detection

According to a method for filtering measurement data of a sensor system (), light pulses () reflected in the environment of the sensor system () are captured by means of an array () of optical detectors (). A multiplicity of measurement signals () are generated by means of the array () based on the captured light pulses. A computing unit () identifies a first measurement signal () whose pulse energy is greater than a specified minimum energy, wherein the first measurement signal () was generated by a first detector (). A second measurement signal () is compared with the first measurement signal () by means of the computing unit (), wherein the second measurement signal () was generated by a second detector (), which is at a distance from the first detector () that is less than or equal to a specified maximum distance. The computing unit discards at least a part of the second measurement signal depending on a result of the comparison.
