The invention relates to a method for the determination of a plurality of distinct echo pulses originating from the same emitted signal train of an active 3D sensor in order to provide distance measurements of the surroundings in front of the 3D sensor, whereas the signal train received by the 3D sensor is subjected to a predefined trigger condition, so that only those peaks of the signal train that fulfill the predefined trigger condition are taken into account in the determination of the distinct echo pulses, According to the invention for the determination of the distinct echo pulses, at least two different trigger conditions are applied simultaneously.

Method for the determination of a plurality of distinct echo pulses in order to provide distance measurements by an active 3D sensor

A method for processing echo pulses of an active 3D sensor to provide distance measurements of surroundings in front of the active 3D sensor includes defining a near range distance from the active 3D sensor and defining a last echo distance from the active 3D sensor greater than said defined near range distance. The method includes receiving a sequence of echo pulses of a signal emitted by the active 3D sensor and subjecting the sequence of echo pulses to a pre-defined trigger condition such that only those echo pulses are taken into consideration which fulfill the predefined trigger condition. The method also includes determining, from the echo pulses which fulfill the predefined trigger condition and that are received from distances greater than a defined near range distance, a first echo pulse and an adaptive echo pulse, and providing distance measurements of the surroundings in front of the 3D sensor using the determined first echo pulse and the determined adaptive echo pulse.

A method of processing 3D sensor data to provide terrain segmentation involves processing the 3D data so as to analyze the positions of sets returns from the terrain in the horizontal plane. Returns from an idealized flat terrain form a series of scanlines in the horizontal plane. A return having a significant displacement in the horizontal plane in comparison to other returns in the same scan line is classified as a non-ground return corresponding to an elevated object.

A man-machine interface for assisting a pilot during takeoff or landing of an airborne vehicle in reduced external visibility includes a display which represents a virtual scenario from the perspective of a virtual observer who is himself located behind the airborne vehicle and is in the same flight attitude as the airborne vehicle itself. The virtual scenario includes a base plane which symbolizes an idealized ground surface, calculated from the instantaneous value of the altitude above ground and the instantaneous flight attitude data of the aircraft. The base plane is bounded by an artificial horizon and is continuously updated with the instantaneous flying state data and the instantaneous height above ground. The virtual scenario also includes a symbol which represents the airborne vehicle, and the position of the symbol relative to the base plane represents the current flight attitude and the instantaneous height of the airborne vehicle above ground.
