Patent number: 11585762Abstract: System and methods used to inspect a moving web (112) include a plurality of image capturing devices (113) that image a portion of the web at an imaging area. The image data captured by each of the image capturing devices at the respective imaging areas is combined to form a virtual camera data array (105) that represents an alignment of the image data associated with each of the imaging areas to the corresponding physical positioning of the imaging areas relative to the web. The image output signals generated by each of the plurality of image capturing devices may be processed by a single image processor, or a number of image processors (114) that is less than the number of image capturing devices. The processor or processors are arranged to generate the image data forming the virtual camera array.Type: GrantFiled: January 28, 2019Date of Patent: February 21, 2023Assignee: 3M Innovative Properties CompanyInventors: Kenneth G. Brittain, Steven P. Floeder

Patent number: 9031312Abstract: A computerized inspection system is described for detecting the presence of non-uniformity defects and providing output indicative of a severity of each type of non-uniformity defect. Techniques are described that increase the throughput of the inspection system. Algorithmic and hardware approaches are described to significantly decrease the average amount of time required to inspect a given quantity of material that is expected to be mostly uniform. The techniques described herein involve dynamic selection of which image features to compute by starting with a base feature set and only triggering additional feature computations as needed until the features are sufficient to compute a severity for each type of non-uniformity defect. The number of features extracted and the order in which the features are extracted is dynamically determined in real-time to reduce a cost associated with the feature extraction.Type: GrantFiled: October 28, 2011Date of Patent: May 12, 2015Assignee: 3M Innovative Properties CompanyInventors: Evan J. Ribnick, Kenneth G. Brittain, John A. Ramthun, Derek H. Justice, Guillermo Sapiro

Patent number: 9002072Abstract: A system is described for detecting the presence of non-uniformity patterns and providing output indicative of a severity of each type of non-uniformity pattern. The system includes a computerized rating tool that assists a user in efficiently and consistently assigning expert ratings (i.e., labels) to a large collection of training images representing samples of a given product. In addition, the rating software develops a model that allows a computerized inspection system to detect the presence of non-uniformity patterns in a manufactured web material in real time and provide output indicative of a severity level of each pattern on a continuous scale. The system also includes algorithmic and hardware approaches to significantly that increase the throughput of the inspection system.Type: GrantFiled: February 14, 2012Date of Patent: April 7, 2015Assignee: 3M Innovative Properties CompanyInventors: Catherine P. Tarnowski, Kenneth G. Brittain, David L. Hofeldt, Andrzej P. Jaworski, Gregory D. Kostuch, John A. Ramthun, Evan J. Ribnick, Esa H. Vilkama, Derek H. Justice, Guillermo Sapiro

Patent number: 8965116Abstract: A computerized rating tool is described that assists a user in efficiently and consistently assigning expert ratings (i.e., labels) to a large collection of training images representing samples of a given product. The rating tool provides mechanisms for visualizing the training images in an intuitive and configurable fashion, including clustering and ordering the training images. In some embodiments, the rating tool provides an easy-to-use interface for exploring multiple types of defects represented in the data and efficiently assigning expert ratings. In other embodiments, the computer automatically assigns ratings (i.e., labels) to the individual clusters containing the large collection of digital images representing the samples.Type: GrantFiled: October 14, 2011Date of Patent: February 24, 2015Assignee: 3M Innovative Properties CompanyInventors: Evan J. Ribnick, Kenneth G. Brittain, Gregory D. Kostuch, Catherine P. Tarnowski, Derek H. Justice, Guillermo Sapiro, Sammuel D. Herbert, David L. Hofeldt
