6.9.2 What Is Smart Matching?
The Smart Matching feature detects the location of the saved base image (a template) within the search area (a
specified area). If as many images as you have set were detected after searching, the positions (X/Y coordinate
values), the Rotation Angle, and similarity degree (a correlation value) of a template is output and then the object
will be judged as "OK". If no image was detected or the number of detected images was less than the specified
"Det. Count", PV310 judges as "NG".
In addition, the function finds an image that matches or resembles the template within the search area based on
the gray value. Searching order is called a "search sequence". Some of the parameters can be changed.
The Smart Matching checker is also provided with a function that is effective if the difference in brightness
between the background and the inspection object is small or some parts of the image of the object may not be
shown on the screen.
