  • Patent number: 11048962
    Abstract: The invention relates to a method and to a device for determining the articulation angle of a combination, consisting of a towing vehicle and a trailer attached using a tongue, by identifying the hitch tongue using a digital back-up camera with variable exposure times, the following steps being carried out: a) recording a first color image of the rear environment of the towing vehicle, the color image being based on the HSY color space, b) analyzing the hue values, saturation values and brightness values of adjacent surfaces of a vehicle-environment region that is to be evaluated, c) determining the tongue from the first color image using an edge detection method in order to determine the articulation angle if the hue values, saturation values and brightness values of adjacent surfaces in the region that is to be evaluated are substantially equal, “substantially equal” meaning that the values of hue, saturation and brightness of adjacent surfaces differ by at most a first threshold in percent, d) recording a

  • Patent number: 10679073
    Abstract: A method for recognizing the shape of an object outside of a transportation vehicle, wherein a respective image is generated at at least two different measurement time points and at least one scanline is specified in a first one of the images and a corresponding scanline is specified in each other of the images, and for each scanline of the first image, a profile resulting along the scanline is determined and a corresponding profile is determined along the respective corresponding scanline of each other image, and by comparing the profile of each scanline of the first image to the respective corresponding profile of each other image a respective displacement distance resulting between the measurement time points of characteristic regions is determined, and a distinction is made of each characteristic region between object and background based on the determined displacement distance.
