Patent number: 8675195Abstract: A device and process for determining sizes of particles of a particle stream. A first optical measuring system with a first dot matrix sensor and a lighting device, which transilluminates the measuring volume are provided. The first dot matrix sensor and the lighting device form a transmitted-light arrangement. The computing device determines projection areas of particles within the transilluminated measuring volume from the image data of the first dot matrix sensor. The optical measuring arrangement includes a second optical measuring system with a second dot matrix sensor for detecting the diffraction pattern of the particles. The computing device determines a size distribution of the particles in the measuring volume based on the projection areas and the diffraction pattern. The computing device forms the size distribution from particle sizes determined on the basis of the projection areas and from particle sizes determined on the basis of the diffraction pattern.Type: GrantFiled: March 23, 2010Date of Patent: March 18, 2014Assignee: Baumer Optronic GmbHInventors: Joachim Ihlefeld, Amer Tarraf

Publication number: 20120002038Abstract: A device and a process, for measuring deformations of an elastically deformable object, provides at least one optically detectable mark at a longitudinal position along the one elastically deformable object, as well as at least one camera with a matrix of photosensitive elements. The camera is directed towards the at least one optically detectable mark such that this is imaged on the matrix of photosensitive elements. The image data of the camera are sent to an image processing device, which is set up to determine the position of the mark on the matrix of photosensitive elements on the basis of an image recognition. A deviation of the position of the optically detectable mark from the at least one set point is determined and quantified by a computing device.Type: ApplicationFiled: February 5, 2010Publication date: January 5, 2012Inventors: Bernhard Furrer, Theo Knaus, Joachim Tiedeke, Joachim Ihlefeld, Christoph Kluser

Patent number: 7978914Abstract: The invention relates to an image processing system for omnidirectional reading of optical patterns, for example of one-dimensional and two-dimensional codes. One object is to provide an image processing system which ensures high resolution with rapid processing at the same time in order, in particular, to allow processing in video real time and to provide reliable identification of the image information, in particular reliable and low-error edge detection, segmentation and object association. According to the invention, this is achieved by the use of a plurality of convolvers, which operate in parallel and/or using the time-division multiplexing method, for convolution of the digital image data, of a neighborhood processor (90) for reading and linking contour points (22), and/or of a statistical processor for reading a segment list.Type: GrantFiled: January 30, 2004Date of Patent: July 12, 2011Assignee: Baumer Optronic GmbHInventors: Lars Beikirch, Sergej Fedorenko, Dittmar Schwarz, Joachim Ihlefeld, Lutz Wenert

Publication number: 20070120844Abstract: A method for configuring, on the basis of only a small number of reference images, image processing systems for the inspection of objects on the basis of geometric primitives extracted from the camera images in video real-time, by a user who is inexperienced in image processing but thinks technically-geometrically and is versed in the function of the objects to be inspected. In this case, the user's semantic knowledge is incorporated into the otherwise automatic calculation of the classifiers for the tolerant and positionally invariant recognition of the objects by virtue of the user, by means of an input device, deleting or else weighting the geometric primitives that are unsuitable for the classification selectively on the graphical interface.Type: ApplicationFiled: November 28, 2005Publication date: May 31, 2007Inventors: Lars Beikirch, Sergej Fedorenko, Dittmar Schwarz, Joachim Ihlefeld, Lutz Wenert
