摘要： This invention provides a vision system housing having a front plate assembly that accommodates a plurality of lens mount types. The front plate includes a central aperture that is located at a predetermined axial (camera axis) distance from a plane of an image sensor. The aperture is stepped from a wider diameter adjacent to the front to a narrower diameter more adjacent to the sensor. This arrangement enables threaded mounting of a plurality of lens mount types, for example M12 and C-Mount. The threaded base for the M12 lens is provided in the smaller-diameter, interior portion of the front plate aperture, adjacent to the sensor. The threaded base for the C-Mount lens is provided at the front of the front plate, adjacent to the exterior surface of the front plate and housing. The exterior (front) surface of the front plate includes threaded holes and a removable spring clip arrangement constructed and arranged to accommodate a liquid lens positioned over the aperture with an associated lens assembly mounted within the aperture and in optical communication with the liquid lens. The lens is operated using an electrical connection provided by a cable that interconnects with a multi-pin socket positioned on the front plate aside the aperture. The socket interconnects with processor circuitry within the housing.

摘要： This invention provides a system and method for determining and controlling focal distance in a lens assembly of a vision system camera using an integral calibration assembly that provides the camera's image sensor with optical information that is relative to focal distance while enabling runtime images of a scene to be acquired along the image axis. The lens assembly includes a variable lens located along an optical axis that provides a variable focus setting. The calibration assembly generates a projected pattern of light that variably projects upon the camera sensor based upon the focus setting of the variable lens. That is, the appearance and/or position of the pattern varies based upon the focus setting of the variable lens. This enables a focus process to determine the current focal length of the lens assembly based upon predetermined calibration information stored in association with a vision system processor running the focus process.

摘要： This invention provides a system and method for employing and analyzing images that are illuminated in different colors depending upon the type of illumination being employed. In an illustrative embodiment, a color image sensor is used to acquire images of subjects of interest, and each of the direct bright field, dark field and diffuse illumination are transmitted to the surface simultaneously (concurrently with each other) in a discrete illumination color that is discretely discernable by the sensor. For example, direct bright field and dark field may be red, while diffuse may be blue. Pixels of the same sensitivity (for example, red and blue) in the image sensor receive only the image generated by that color of illumination. The reader of this invention includes processing components that independently assemble images from red and blue pixel addresses to create, in effect two simultaneous images (one image generated using a combination dark field and direct bright field and the other image generated using diffuse illumination) that overlap (are registered with respect to each other) perfectly. The best image is determined using conventional image analysis tools, and meaningful data (the code of the read symbol, for example) is derived from that best image.

摘要： A hand held industrial identification symbol reader projects diffuse illumination onto a region of interest to produce high contrast images of symbols. The diffuse illumination is particularly well suited for producing images of symbols that are marked directly on objects. The diffuse illumination is created through the use of an optically translucent diffuser having a generally tapered shape that distributes diffuse illumination throughout the field of view of the reader. The diffuse illumination can be supplemented with dark field illumination using selectively actuated illumination sources.
