With the help of ActivAlignment, you can align the regions of interest (ROIs) of other ActivVisionTools to moving parts. In other words, you can "anchor" a ROI to a certain object in the image; if the object moves from image to image, the ROI moves with it. To anchor a ROI to an object, you must first teach ActivAlignment how to recognize the object in an image. For this, you need one so-called reference image; in it, you select a part which is to act as the alignment anchor, i.e., by which the object can be recognized.

In the application phase, ActivAlignment automatically locates the alignment anchor precisely in the current image and aligns the ROIs of other tools accordingly.
