| 20110119242 | SEARCH ENGINE QUERY CUSTOMIZATION AND SEARCH SITE RATING SYSTEM - A method and system are provided for web search customization and web site rating. The system receives user input web sites, stores the web sites in a database, and groups them into user-specified categories. The system further allows users to select one or more web sites for customizing web search and querying the preselected sites using user input keywords. The system further provides the users with options to query a plurality of search engines. All web sites stored within the system are rated in response to the user operations. Each web site has at least a global rating indicating the rating within the system, a category rating indicating the rating within a given category, and a keyword rating indicating the rating for a given keyword. The system provides the users with a list of recommended web sites based on the web sites' ratings. | 05-19-2011 |

| 20100166294 | SYSTEM AND METHOD FOR THREE-DIMENSIONAL ALIGNMENT OF OBJECTS USING MACHINE VISION - This invention provides a system and method for determining the three-dimensional alignment of a modeledobject or scene. After calibration, a 3D (stereo) sensor system views the object to derive a runtime 3D representation of the scene containing the object. Rectified images from each stereo head are preprocessed to enhance their edge features. A stereo matching process is then performed on at least two (a pair) of the rectified preprocessed images at a time by locating a predetermined feature on a first image and then locating the same feature in the other image. 3D points are computed for each pair of cameras to derive a 3D point cloud. The 3D point cloud is generated by transforming the 3D points of each camera pair into the world 3D space from the world calibration. The amount of 3D data from the point cloud is reduced by extracting higher-level geometric shapes (HLGS), such as line segments. Found HLGS from runtime are corresponded to HLGS on the model to produce candidate 3D poses. A coarse scoring process prunes the number of poses. The remaining candidate poses are then subjected to a further more-refined scoring process. These surviving candidate poses are then verified by, for example, fitting found 3D or 2D points of the candidate poses to a larger set of corresponding three-dimensional or two-dimensional model points, whereby the closest match is the best refined three-dimensional pose. | 07-01-2010 |
| 20110157373 | SYSTEM AND METHOD FOR RUNTIME DETERMINATION OF CAMERA MISCALIBRATION - This invention provides a system and method for runtime determination (self-diagnosis) of camera miscalibration (accuracy), typically related to camera extrinsics, based on historical statistics of runtime alignment scores for objects acquired in the scene, which are defined based on matching of observed and expected image data of trained object models. This arrangement avoids a need to cease runtime operation of the vision system and/or stop the production line that is served by the vision system to diagnose if the system's camera(s) remain calibrated. Under the assumption that objects or features inspected by the vision system over time are substantially the same, the vision system accumulates statistics of part alignment results and stores intermediate results to be used as indicator of current system accuracy. For multi-camera vision systems, cross validation is illustratively employed to identify individual problematic cameras. The system and method allows for faster, less-expensive and more-straightforward diagnosis of vision system failures related to deteriorating camera calibration. | 06-30-2011 |
