  • Patent number: 10775160
    Abstract: This invention provides a system for measuring displacement of an object surface having a displacement sensor that projects a line on the object surface and receives light from the projected line at an imager in a manner defines a plurality of displacement values in a height direction. A vision system processor operates on rows of imager pixels to determine a laser line center in columns of imager pixels in each of a plurality of regions of interest. Each region of interest defines a plurality of rows that correspond with expected locations of the projected line on the object surface. A GUI can be used to establish the regions. In further embodiments, the system generates grayscale images with the imager. These grayscale images can be compared to a generated height image to compensate for contrast-induced false height readings. Imager pixels can be compared to a reference voltage to locate the line.

  • Patent number: 10393575
    Abstract: Techniques are provided to perform flat field correction for infrared cameras using a liquid shutter. Devices and methods provide a focal plane array (FPA) that receives infrared radiation (e.g., thermal infrared radiation) from a scene, and infrared-opaque liquid disposed in a cavity of a liquid shutter housing, and a fluid controller that directs the liquid from a reservoir area of the cavity to a field of view area of the cavity to block the FPA from the infrared radiation. Flat field correction terms may be determined and radiometric calibration may be performed. In one example, a liquid shutter uses voltages to direct liquid. In another example, a liquid shutter uses magnetic fields from electromagnets to direct liquid such as ferrofluid. In another example, a liquid shutter uses electrowetting techniques to direct liquid such as water. In a further example, a liquid shutter uses a pump.

  • Patent number: 9554094
    Abstract: A system and method for detecting and/or determining the existence of displacement of a substrate with respect to a surrounding object uses a laser line that is free of contact with the object and that is received by an image sensor. A processor reads the line information in a series of image frames, and generates a range image with height information. The height information is provided to a 2D map. Differences between adjacent height measurements, and averages, are computed. Vision system tools are used to accurately locate features in the image and these are aligned with the height information. The height differences are interpreted, with missing height data due, for example, to specularity in the image being approximated. The height differences are compared to predetermined height parameters relative to identified locations, for example, wells, in the object to determine whether a substrate is displaced.

  • Patent number: 9292187
    Abstract: A graphical user interface (GUI) display and GUI-based system for displaying and controlling vision system operating parameters of a contour sensor comprises an automated region of interest graphic image applied to a discrete region of a selected image in response to a single click by a user at the discrete region of the selected image, the selected image selected from a window on the GUI display containing a plurality of captured images of the object. At least one automated operating parameter is generated automatically in response to the single click by the user at the discrete region of the selected image to determine whether a contour of interest is in the automated ROI graphic image. The GUI also provides a contour graphic image that outlines the contour of interest to demonstrate whether the contour of interest is in (present or at the correct position within) the automated ROI graphic image.

  • Patent number: 9039208
    Abstract: 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.

  • Patent number: 8782553
    Abstract: 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.
