20110317001 | MULTISENSOR ARRAY FOR THE OPTICAL INSPECTION AND SORTING OF BULK MATERIALS - A Multisensor array optically inspects and sorts bulk materials into different fractions, in which the bulk material stream is detected from a short distance compared to the width of the bulk material stream with at least two identical camera and lighting modules arranged adjacent to each other. The width of the image of the cameras is smaller than the width of the bulk material stream. The image sensors and lighting devices are limited to the range of the wavelengths of 380 nm to 1,000 nm covered by CMOS and/or CCD image sensors. Each camera is connected by a mechanical bracket and is equipped with at least one and preferably with a set of linearly lighting semiconductor light sources, which emit in a narrow band and are pulsed synchronously with the line frequency of the camera. The linearly lighting light sources can be replaced by a changing mechanism of the bracket, which mechanism is connected to the camera, to other light sources, especially ones having different system parameters. The actuating signals of the lighting sources pulsed synchronously with the line cycle of the image sensors can be generated by an electronic device according to a variable synchronization diagram, which can be optimized for the discrimination of the fractions of the bulk material stream. The signals of the camera or cameras are analyzed by at least one image computer by pattern recognition and classification for recognizing, assigning and rating the particles of the at least two fractions. Timely ejection signals are generated by a control device by real-time image processing operators in order to remove particles of at least one fraction to be removed from the bulk material stream with ejectors. | 12-29-2011 |
20110206242 | Instrumental Support for Monitoring the Color Imprint in the Manufacture of Surfaces Patterned in Multiple Colors - A method is disclosed that relates to maintaining or improving the end quality of the visual color imprint of multiple-colored patterned surfaces. These surfaces cannot be measured using the decorations that are manufactured by printing processes, the so-called primary decoration, because subsequent processes change the color imprint further resulting in the so-called secondary color imprint. According to the invention, prediction rules are determined based on samples from the primary and secondary decorations during a learning phase to establish from n-channel images of samples of the primary decoration color imprint characteristics and convert those to such characteristics for the secondary decoration; and/or to establish from n-channel images of samples of the primary decoration images of the secondary decoration and to calculate color imprint characteristics. Color imprint characteristics are extracted and converted with the aid of the prediction rules to the color imprint characteristics of the secondary decoration, and applied. | 08-25-2011 |
20100208058 | MONITORING THE COLOR IMPRESSION OF MULTICOLOR PATTERNED AREAS - A method and an arrangement for testing the quality of multicolor patterned surfaces with an n-channel imaging sensor such as a color camera or an imaging spectrometer. The method determines from the captured images the deviations of the color/spectral statistics and of the image sharpness with respect to references and, before an assessment, converts at least one of the deviations or threshold values using a transformation which emulates the genetically and/or culturally specific perception of the targeted customer groups. The method further allows a quality produced to be associated with a genetically and/or culturally specific group of customers who accept this quality in terms of their perception of multicolor patterned surfaces. | 08-19-2010 |
