Abstract (en)
[origin: CA3072010A1] Proposed is a method (100) for optical distance measurement, which involves transmitting (107) measuring pulses by means of a transmission matrix comprising a plurality of transmission elements, reflecting (108) transmitted measuring pulses to at least one object, and receiving (109) reflected measuring pulses by means of a reception matrix (11). The reception matrix (11) comprises a plurality of reception elements (12) each having a plurality of reception sub-elements (13). The method involves monitoring (101) reception rates of reception sub-elements (13) of the reception matrix (11) for determining (112) a misalignment between the transmission matrix and reception matrix (11), wherein the transmission matrix and reception matrix define a visual field, and wherein the method (100) is used for the navigation of a vehicle. Monitoring (101) takes place while a vehicle is traveling, wherein the method (100) does not involve the conscious introduction of measuring objects into the visual field for determining a misalignment.
