Patent number: 8740081Abstract: A method and apparatus for decoding codes applied to objects for use with a camera and a conveyor system wherein the camera includes an image sensor having a two dimensional field of view (FOV), the method comprising the steps of providing a processor programmed to perform the steps of obtaining images of the FOV, for each image identifying code candidates in at least portions of the image, ordering at least a subset of the code candidates for decoding in a candidate order wherein the candidate order is determined at least in part as a function of a first direction of travel through the FOV, attempting to decode code candidates in the order specified by the direction of travel and when a new image event occurs, foregoing attempts to decode at least a portion of the identified code candidates.Type: GrantFiled: November 3, 2011Date of Patent: June 3, 2014Assignee: Cognex CorporationInventors: James Negro, John F.

Publication number: 20140119661Abstract: Systems and methods for use with a mark reader that reduce the trigger-to-decode response time by prioritizing images to be decoded based on the likelihood of a successful decode are provided. A reader attempts to decode a priority image(s) first to avoid attempting to decode images that are less likely than other images to be successfully decoded. Images are rated based on feature attributes, and then prioritized for decoding. Image feature attributes are correlated with parameter groups, and the parameter groups are prioritized for use in subsequent image acquisitions.Type: ApplicationFiled: August 29, 2013Publication date: May 1, 2014Applicant: COGNEX CORPORATIONInventors: James A. Negro, John F. Keating

Patent number: 8582925Abstract: This invention provides a system and method for employing GUI-based non-numeric slide buttons and bar meters to setup and monitor operating parameters of a vision system. Graphical representations of operating parameters are displayed in a parameter box on the GUI with moving bars that are shaded, patterned or colored so as to provide a relative level between two extremes on a scale of the given operating parameter. Input of operating parameter settings with respect to the scale is made by moving a setting slider along the scale between the extremes. The position of the slider establishes the user-input setting relative to the scale. In an illustrative embodiment, scales, level bars and setting sliders can also be displayed on the image view itself, adjacent to a given image view feature, which is the subject of the scale.Type: GrantFiled: April 12, 2010Date of Patent: November 12, 2013Assignee: Cognex Technology and Investment CorporationInventors: Brian V. Mirtich, Andrew Eames, Brian S. Phillips, Robert J. Tremblay, II, John F. Keating, Steven Whitman

Publication number: 20120120490Abstract: The invention provides, in some aspects, devices for image acquisition that use seals between concentrically disposed portions of an enclosure and an optics assembly in order to protect image acquisition components from the surrounding environment while providing adequate friction for both adjusting and locking focus. Such devices can include an image capture medium that is disposed within an enclosure and an optics assembly that is also disposed within that enclosure. The optics assembly, which includes at least a lens, can have a cylindrical outer diameter along at least a portion of its length that is received within the enclosure along a length that has a corresponding cylindrical inner diameter. A first seal is disposed between, and in contact with, the optics assembly and the enclosure. That seal permits rotation of the optics assembly for purposes of focusing the lens, while preventing contamination from the environment from entering into the enclosure.Type: ApplicationFiled: October 10, 2011Publication date: May 17, 2012Applicant: COGNEX CORPORATIONInventors: George Costigan, Steven N.

Patent number: 8127247Abstract: This invention provides a Graphical User Interface (GUI) that operates in connection with a machine vision detector or other machine vision system, which provides a highly intuitive and industrial machine-like appearance and layout. The GUI includes a centralized image frame window surrounded by panes having buttons and specific interface components that the user employs in each step of a machine vision system set up and run procedure. One pane allows the user to view and manipulate a recorded filmstrip of image thumbnails taken in a sequence, and provides the filmstrip with specialized highlighting (colors or patterns) that indicate useful information about the underlying images. The programming of logic is performed using a programming window that includes a ladder logic arrangement.Type: GrantFiled: December 27, 2006Date of Patent: February 28, 2012Assignee: Cognex CorporationInventors: Robert J. Tremblay, Brian S. Philips, John F. Keating, Andrew Eames, Steven Whitman, Brian V. Mirtich, Carroll McNeil Arbogast, Jr.

Patent number: 8033670Abstract: The invention provides, in some aspects, devices for image acquisition that use seals (e.g., O-rings) between concentrically disposed portions of an enclosure and an optics assembly (or sub-assemblies thereof) in order to protect image acquisition components from the surrounding environment (and vice versa) while, at the same time, providing adequate friction for both adjusting and locking focus. Such devices include, in one aspect of the invention, an image capture medium (e.g., a CMOS sensor, CCD array, etc.) that is disposed within an enclosure and an optics assembly that is also disposed within that enclosure, rotatably. The optics assembly, which includes at least a lens, can have a cylindrical outer diameter along at least a portion of its length that is received within the enclosure along a length that has a corresponding cylindrical inner diameter. A first seal (e.g., an “O-ring”) is disposed between, and in contact with, the optics assembly and the enclosure, e.g., along these corresponding lengths.Type: GrantFiled: December 29, 2006Date of Patent: October 11, 2011Assignee: Cognex CorporationInventors: George Costigan, Steven N.

Publication number: 20100241981Abstract: This invention provides a system and method for employing GUI-based non-numeric slide buttons and bar meters to setup and monitor operating parameters of a vision system (the term “vision system” as used herein including the above-described vision detector). Such parameters can include, but are not limited to the threshold at which a feature is activated in viewing an image. Operating parameters also include the underlying range of contrast values and levels of brightness intensities (or by input inversion, the level of darkness) recognized and acted upon by the vision system. Graphical representations of operating parameters are displayed in a parameter box on the GUI with moving bars that are shaded, patterned or colored so as to provide a relative level between two extremes on a scale of the given operating parameter. The endpoints of the scale can be established by analyzing the relevant extremes on a subject image view.Type: ApplicationFiled: April 12, 2010Publication date: September 23, 2010Inventors: Brian V.

Such parameters can include, but are not limited to the threshold at which a feature is activated in viewing an image. Operating parameters also include the under-lying range of contrast values and levels of brightness intensities (or by input inversion, the level of darkness) recognized and acted upon by the vision system. Graphical representations of operating parameters are displayed in a parameter box on the GUI with moving bars that are shaded, patterned or colored so as to provide a relative level between two extremes on a scale of the given operating parameter.

Patent number: 7636449Abstract: This invention provides a system and method for automating the setup of Locators and Detectors within an image view of an object on the HMI of a vision detector by determining detectable edges and best fitting the Locators and Detectors to a location on the object image view following the establishment of an user selected operating point on the image view, such as by clicking a GUI cursor. In this manner, the initial placement and sizing of the graphical elements for Locator and Detector ROIs are relatively optimized without excessive adjustment by the user. Locators can be selected for direction, including machine or line-movement direction, cross direction or angled direction transverse to cross direction and movement direction. Detectors can be selected based upon particular analysis tools, including brightness tools, contrast tools and trained templates.Type: GrantFiled: November 12, 2004Date of Patent: December 22, 2009Assignee: Cognex Technology and Investment CorporationInventors: Brian V.
