A procedure and system are provided for automatically landing an aircraft, particularly an unmanned aircraft on a moving, particularly floating landing platform, for example, on an aircraft carrier, the aircraft being equipped with an automatic navigation device and an automatic landing control device. The procedure includes detecting the position of an intended landing spot, detecting motion data of the landing platform, determining at least one imminent point in time at which the landing spot takes up a reference position, transmitting the point in time and the reference position of the landing spot to the landing control device of the aircraft, and controlling the aircraft such that it reaches the landing spot at the point in time.

In a method for identifying and classifying an object, an object is detected by at least one physical detector tuned for it, the object is evaluated from the output signal of the detector and by an evaluation unit, and the object is identified and/or classified on the basis of predefinable properties from the output signal. A number of different physical features of the object are derived from the output signal, and the object is assigned to one of N predetermined basic classes on the basis of the derived physical features. The N basic classes are arranged in a predetermined order to form an N-dimensional vector V, which is assigned to the object, such that the elements v1, . . . , vN of the vector V indicate that the object belongs to the respective basic class. The object is then assigned to a derived class, which is taken from a reference data base, as a function of the vector V.

In a method for determining object edge curves in a recorded image of a multispectral camera, the image recorded is converted into a false color image, hue value from the HSV color space is assigned to each pixel in the false color image such that the hue value corresponds to a hue angle on a predetermined color circle, and the pixels are classified as object pixels and background pixels, such that those pixels with hue values that are within a predetermined value range are defined as the object pixels. An entropy profile is then determined by way of a displaceable evaluation window, such that the entropy of mixing S is calculated for each pixel from the object pixels and background pixels according to the equation: S = - k ( n A ln n A n A + n B + n B ln n B n A + n B ) where nA denotes the number of object pixels within the evaluation window, nB denotes the number of background pixels within the evaluation window and k is a proportionality factor.

摘要:
A method for recognizing an object that has a plurality of expressions of abstract object characteristics, and is associated with an object characteristic class of a hierarchical system of object characteristic classes stored in a first memory. The method includes i) observing at least one location at which the object is presumed to be present, using a plurality of sensors in a sensor population, each of said sensors responding to at least one object characteristic and accordingly emitting a sensor signal; ii) checking whether each of the emitted sensor signals exceeds a specified threshold value for the sensor signals, and accepting sensor signals which exceed the threshold value; iii) pairing combinations of the sensor characteristics, for the accepted sensor signals obtained in ii) to form identification characteristic pairs; iv) comparing the population of identification characteristic pairs obtained in iii) to the object characteristic classes stored in the first memory; and v) identifying the object, based on the object characteristic class, whose object characteristic pairs are identical to the identification characteristic pairs obtained in iii).

A method for the identification of objects in a predetermined target area involves recording a first and a second height profile of the target area, wherein the two height profiles are recorded at a predeterminable time interval. A height difference profile is determined from the first and the second height profile. The height difference profile is subdivided in equidistant horizontal height sections. The positions of the centroids of the surface areas enclosed by the respective contour lines of the horizontal height sections are calculated and the determined height difference profile and the calculated centroids of the surface areas are supplied to a system for classifying objects.
