Abstract: A method for positioning an access or loading assembly against the fuselage of an aircraft during the loading or unloading process, in which at least two multichannel scanners are oriented toward the aircraft fuselage and disposed above one another at a distance from each other, each with several light emitting units and at least one detector. First, a reference position is determined by using the scanners, then a current position of the aircraft fuselage relative to the access or loading assembly is determined at determined time intervals by the multichannel scanners. The current position is compared with the reference position to determine a deviation. In case of a deviation between the two positions, a signal is transmitted to the control system of the positioning drive for realigning the access or loading assembly and reducing the deviation.

Abstract: The invention relates to a method for detecting objects in which a light pattern is beamed by a plurality of transmitting modules into an observation zone, the transmitting modules being spaced to each other, in which light radiated back from the observation zone is detected by at least one spatially resolving detector unit, in which a surface contour of an object located in the observation zone is determined on the basis of the detected light according to the light section principle, in which a maximum spatial resolution is caused by the intervals at which the transmitting modules are spaced from each other.
