  • Patent number: 6064478
    Abstract: In a method of and an apparatus for detecting three-dimensional defects in he automatic inspection of moving surfaces by means of a color vision system the surface of a moving test specimen which is to be inspected is illuminated with light of different colors simultaneously from at least two different directions, such that edges of three-dimensional defects on the surface appear with a different coloring, and on the basis of the altered coloring, at least two channels of the color image are evaluated to detect three-dimensional defects and to differentiate same from planar defects.

  • Patent number: 5586663
    Abstract: The invention relates to a process for the optical sorting of bulk material in a colour-sorting machine while it is conveyed over a transport belt and moves past an observation head with a light source and a product signal receiver arranged in the vicinity of the light source, whereby the reflected light of the image points of the examination material is broken down into several spectral ranges by various colour filters of detection elements lying next to one another of a line of the receiver and the examination material is sorted on the basis of the colour values (measured value of the intensity in the colour in question).

  • Patent number: 5120952
    Abstract: In a device for ascertaining the actual feed transmittted by an feed device f an industrial sewing machine to a material to be sewn, in which the number of the threads moved across a sensor arrangement is counted and the feed is calculated from the previously detected thread density, it is provided, for obtaining an exact thread count which is as independent as possible of the orientation of the sewn web, to place ahead of the photocell (10) of the sensor arrangement a rotating slit diaphragm (7) with at least one radially extending parallel limited slit (8). Preferably a second, rotationally adjustable, but fixed slit diaphragm (5) is provided, having slits (6) opening across a set angular sector, the rotatitng slit diaphragm (7) having a larger number of slits (8). Because of this the required rpm of the slit diaphragm (7) can be reduced. To avoid errors caused by the pattern of the material it is possible to operate in the relatively longer wave infrared spectrum.

  • Patent number: 5103749
    Abstract: Patterns of two fabric layers are each recognized by a camera and the fabric layers are aligned to make these patterns agree in the transverse and longitudinal directions. According to the invention the influence of speed-related disturbance variables and pattern-related limitations during the generation of the signal is reduced. Two-dimensional images of the two fabric layers are recorded with a matrix camera each during a pause between feeds. The degree of congurence of the fabric layers according to the pattern is determined by two-dimensional cross-correlation analysis of the image points arranged in rows and columns. Aligning correction values are calculated from this degree. The edge distance of the fabric layers is determined with a section of the matrix sensors, which is a separate section in terms of evaluation. Based on the edge distance data, the lower fabric layer is adjusted to the correct distance continuously and the upper fabric layer is adjusted as needed.

  • Patent number: 4612867
    Abstract: A method and apparatus for the pattern-correct sewing together of two pieces of cloth having the same pattern by a sewing machine with one cloth feed mechanism arranged over and one arranged under the cloth pieces, the feed quantity of which is variably by at least one positioning system relative to each other, uses a sensor arranged upstream of a stitch forming point for each cloth piece and a signal processing unit which processes signals from the sensors corresponding to the relative position of the cloth pieces and which influences the positioning system for the feed mechanism in accordance with the established relative position of the cloth pieces. For the pattern-correct sewing together of the two cloth pieces, the pattern structure of each cloth piece is continuously determined by the sensors by measuring values of a structure-or pattern-typical criterion.
