摘要： A distance measure between a beginning and an end of a material strip wound onto a body in a tangential direction can be determined by creating a height profile of a surface of the material strip, which covers the beginning and the end of the wound material strip in the tangential direction. If a position value of the beginning of the material strip is determined in the created height profile, the distance measure can be determined using this position value and the height profile covering the end of the material strip.

摘要： A device for detecting a plant against a background includes a provider for providing a plurality of different photographs of the plant leaf against the background, the photographs differing in that image points of the different photographs relating to the same location of the plant leaf are illuminated with different levels of brightness, a selector for selecting such image points, from the different photographs, whose levels of brightness are within a predetermined range, an image point of a first photograph being selected for a first location of the plant leaf, and an image point of a second, different photograph being selected for a different location of the plant leaf to obtain a representation of the plant leaf against the background, the representation being composed of and/or merged from different photographs, and a segmenter for segmenting the composite photograph to obtain a segment representation having the plant leaf without the background or the background without the plant leaf.
