  • Publication number: 20210310799
    Abstract: An apparatus for capturing at least partially reflective surfaces includes a detection surface assembly, an illumination device configured to emit an illumination pattern toward the at least partially reflective surface so as so project, by reflection via the at least partially reflective surface, a first reflection pattern and a second reflection pattern onto the detection surface assembly. The apparatus includes a capturing unit configured to capture the first reflection pattern and the second reflection pattern from the detection surface assembly.

  • Patent number: 9342895
    Abstract: 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.

  • Patent number: 8340402
    Abstract: A device for detecting a plant includes a two-dimensional camera for detecting a two-dimensional image of a plant leaf having a high two-dimensional resolution, and a three-dimensional camera for detecting a three-dimensional image of the plant leaf having a high three-dimensional resolution. The two-dimensional camera is a conventional high-resolution color camera, for example, and the three-dimensional camera is a TOF camera, for example. A processor for merging the two-dimensional image and the three-dimensional image creates a three-dimensional result representation having a higher resolution than the three-dimensional image of the 3D camera, which may include, among other things, the border of a leaf. The three-dimensional result representation serves to characterize a plant leaf, such as to calculate the surface area of the leaf, the alignment of the leaf, or serves to identify the leaf.
