Abstract: A method for optical distance measurement involves transmitting measuring pulses by means of a transmission matrix having a plurality of transmission elements, reflecting transmitted measuring pulses to at least one object, and receiving reflected measuring pulses by a reception matrix. The reception matrix includes a plurality of reception elements each having a plurality of reception sub-elements. The method involves monitoring reception rates of reception sub-elements of the reception matrix for determining a misalignment between the transmission matrix and reception matrix, wherein the transmission matrix and reception matrix define a visual field, and wherein the method is used for the navigation of a vehicle. Monitoring takes place while a vehicle is traveling, wherein the method does not involve the conscious introduction of measuring objects into the visual field for determining a misalignment.

Abstract: The invention relates to a method for optical distance measurement which includes the steps of emitting measurement pulses by a transmission unit and receiving measurement pulses reflected by an object by a receiver unit to identify objects within a field of view of the receiver unit. A background signal is received by receiver elements and the intensity of the background signal is determined for each receiver element, wherein the determined intensities of the background signal are compared in order to identify objects not identified by the measurement within the field of view of the receiver unit. At least one region of minimal intensity of the background signal is established within an intensity image of the field of view of the receiver unit. The region of minimal intensity is assigned a masking in the field of view, the masking originating from an object not identified by the measurement.
