Abstract (en)

[origin: WO2021078557A1] According to a method for filtering measurement data of a sensor system (2), light pulses (5) reflected in the surroundings of the sensor system (2) are captured by an array (7) of optical detectors (8, 9, 10). The array (7) generates a plurality of measurement signals (11, 12) on the basis of the captured light pulses. A first measurement signal (11) is identified by a processor (3), the pulse energy of which signal is greater than a predefined minimum energy, wherein the first measurement signal (11) was generated by a first detector (8). Using the processor (3), a second measurement signal (12) is compared with the first measurement signal (11), wherein the second measurement signal (12) was generated by a second detector (9) which is at a distance from the first detector (8) that is smaller than or equal to a predefined maximum distance. The processor discards at least part of the second measurement signal on the basis of a result of the comparison.
