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.

The resolution of an optical measurement system for measuring a surface of an object, wherein a measurement light strip is captured on a surface of an object by means of a matrix sensor with a resolution limited by quantization in a quantization direction, can be improved by calculating an effective mapping location in the quantization direction on the basis of the associated real mapping location and a further real mapping location adjacent to the associated real mapping location in a direction perpendicular to the quantization direction.

The material strength of extensive objects can be determined efficiently by using two distance measures, wherein a first distance measurer determines the distance to a first main surface of the object and a second distance measurer determines the distance to a second main surface object opposing the first main surface. If potential measurement errors due to the extensive geometry are avoided by determining a reference distance between the first distance measurer and the second distance measurer by a reference object, the thickness of the object between the first main surface and the second main surface can be determined with high accuracy and velocity.

In order to detect an image generated by an image source, a mirror arrangement is arranged between the image source and a detector. The mirror arrangement includes two spaced-apart deflection mirrors, which are parallel to each other or form an acute angle of less than 90° between them. In particular when the image source is a scintillator layer, shielding of X-rays from the detector with simultaneous compact dimensioning of the apparatus is achieved in this manner.

For generating a two-dimensional representation of an object portion arbitrarily arranged within an object, a first image comprising the object, and subsequently a second image comprising the object are generated by means of an imaging device while the object and the imaging device are moving relative to each other. By means of a signal processor, information about a position and a shape of the object portion of interest within the object and its relative motion is received so as to combine, on the basis of the information received, image portions, within the first and second images, which are associated with the object portion of interest.

The material strength of extensive objects can be determined efficiently by using two distance measurers, wherein a first distance measurer determines the distance to a first main surface of the object and a second distance measurer determines the distance to a second main surface object opposing the first main surface. If potential measurement errors due to the extensive geometry are avoided by determining a reference distance between the first distance measurer and the second distance measurer by a reference unit via X-radiation, the thickness of the object between the first main surface and the second main surface can be determined with high accuracy and velocity.

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.

Objects impinging on an impingement body may be classified, with regard to their properties, in an efficient and highly reliable manner when the chronological acceleration profile caused by the object impinging on the impingement body is evaluated so as to classify the object.
