Patent number: 11967090Abstract: For detecting movements of a sample with respect to an objective, the sample is imaged onto an image sensor comprising an array of pixels by means of the objective. Images of the sample are recorded in that light coming from the sample is registered at the pixels. Variations of intensities of the light coming from the sample and registered at the pixels are determined during a set-up period in that a temporal course of the intensity of the light, which has been registered at a respective one of the pixels over the set-up period, is analyzed. Using these variations as a criterion, a subset of not more than 90% of the pixels of the image sensor is selected. Parts of the images that each correspond to the selected subset are compared to parts of at least one reference image that also correspond to the subset.Type: GrantFiled: October 13, 2021Date of Patent: April 23, 2024Assignee: Abberior Instruments GmbHInventor: Roman Schmidt

Patent number: 11699247Abstract: 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.Type: GrantFiled: December 24, 2009Date of Patent: July 11, 2023Assignee: Cognex CorporationInventors: Xiangyun Ye, David Y.
