摘要： Systems and methods trigger an image acquisition of an object using motion data communicated from a motion controller on a network, the motion controller coupled to a motion drive. A camera, upon receiving motion data from the motion controller, uses a virtual axis application to plan the movement of a virtual axis for a motion cycle, the virtual axis allowing an acquisition trigger rate to be calculated by the camera that follows movement of the object caused by the motion drive. Based on the calculated acquisition trigger rate, the camera generates an acquisition trigger signal for triggering the image acquisition of the object.

摘要： This invention provides a system and method for hand-eye calibration of a vision system using an object under manufacture having at least one feature. The feature can be a linear feature and the object moves in at least one degree of freedom in translation or rotation on a motion stage. The system further comprises at least a first vision system camera and vision processor. The first vision system camera is arranged to acquire an image of the first linear feature on the object under manufacture and to track motion of the first linear feature in response to moving of the motion stage in at least one degree of translation. The first linear feature is identified in at least two different positions along a plane. The system computes a mapping between pixel positions in a pixel coordinate system of the first camera and physical positions in a motion coordinate system based upon locations of the at least two positions.

摘要： 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.

摘要： This invention provides a system and method for synchronization of vision system inspection results produced by each of a plurality of processors that includes a first bank (that can be a “master” bank) containing a master vision system processor and at least one slave vision system processor. At least a second bank (that can be one of a plurality of “slave” banks) contains a master vision system processor and at least one slave vision system processor. Each vision system processor in each bank generates results from an image acquired and processed in a given inspection cycle. The inspection cycle can be based on an external trigger or other trigger signal, and it can enable some or all of the processors/banks to acquire and process images at a given time/cycle. In a given cycle. each of the multiple banks can be positioned to acquire an image of a respective region of a plurality of succeeding regions on a moving line. A synchronization process (a) generates a unique identifier and that passes a trigger signal with the unique identifier associated with the master processor in the first bank to each of the slave processor in the master bank and each of the master and slave processor and (b) receives consolidated results via the master processor of the second bank, having the unique identifier and consolidated results from the results from the first bank. The process then (c) consolidates the results for transmission to a destination if the results are complete and the unique identifier of each of the results is the same.

摘要： 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.

摘要： This invention provides a vision system with an exchangeable illumination assembly that allows for increased versatility in the type and configuration of illumination supplied to the system without altering the underlying optics, sensor or vision processor, and their associated housing. The vision system housing includes a front plate that optionally includes a plurality of mounting bases for accepting different types of lenses. An optional connector is provided on the front plate to accept an electrical connection for a liquid lens component. The front plate includes a connector that allows removable interconnection with the illustrative illumination assembly. The illumination assembly includes a cover that is light transmissive on at lest the front face thereof. The cover encloses an illumination component that can include a plurality of lighting elements that surround an aperture through which received light rays from the imaged scene pass through to the lens. The rear face of the illumination component is spaced apart from the rear edge of the cover, which removably and sealingly engages the front plate. The assembly also includes a connector that removably engages the connector on the front plate. The arrangement of lighting elements (e.g. LEDs) is highly variable and the user can be supplied with an illumination assembly that best suits its needs without need to change the vision system processor, sensor or housing.

摘要： This invention provides an electro-mechanical auto-focus function for a smaller-diameter lens type that nests, and is removably mounted, within the mounting space and thread arrangement of a larger-diameter lens base of a vision camera assembly housing. In an illustrative embodiment, the camera assembly includes a threaded base having a first diameter, which illustratively defines a C-mount base. A motor-driven gear-reduction drive assembly is mounted internally, and includes teeth that engage corresponding teeth on the outer diameter of a cylindrical focus gear, which has an internal lead screw. The focus gear is freely rotatable, and removably captured, within the threaded C-mount base in a nested, coaxial relationship. The internal lead screw of the focus gear threadingly engages the external threads of a coaxial lens holder. This converts the drive gear rotation into linear/axial lens holder motion. The lens holder includes anti-rotation stops, which allow its linear/axial movement but restrain any rotational motion.
