Vision Tools Vision Tools ACE Sight software provides an extensive set of vision tools for basic and complex applic- ations. These tools include rulers for measuring distances, windows for calculating the intensity ranges in an image, and finder tools for locating lines, circles, and other features of objects. Each of these tools requires several pieces of information to know what data to collect, how to interpret the data, and where in the camera field of view to look for that data. ACE Sight software allows you to specify all this information, either by making menu selections, or by using the mouse to manipulate the tools directly.
Region of Interest The area of the image in which the tool carries out its process or operation is called the region of interest (ROI). l A vision tool can be positioned to operate on the entire image. l Inspection tools are usually applied to a specific part of the image, or to a specific area relative to an object. Tools can be positioned from the Region of Interest dialogs and in the Display window. NOTE : There are several related tools, not covered in this topic. See See "Communication Tool",Overlap Tool on page 618, and ACE Sight Sequence on page 608 . Locator and Finder Tools The Locator and Finder Tools create a description of objects or object features using vectors.
These tools are typically faster, more reliable, and more accurate than greyscale (rasterized) inspection tools. Locator, Locator Model The Locator identifies instances of model-defined objects. Models characterize object types and are created and edited through the Locator's Model Editor. The Locator is the ideal frame-provider tool for positioning inspection tools. See "Loc- ator" and See "Locator Model". Arc Finder The Arc Finder identifies circular features on objects and returns the coordin- ates of the center of the arc, the angle of separation between the two ends, and the radius. See "Arc Finder". ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 345
