The blue X marks the target position chosen by the search algorithm. The green X
marks indicate other marks in the search zone which also match the search
parameters. The search algorithm will always choose exactly one best match
point. In this example, it will be the top-left-most location with the best score in
the search area.
Note that the search area box (the blue box) has moved to be centered around our
newly
specified ideal location (see the image on the previous product).
The size of the search area can be adjusted by setting the Range values. For
optimal performance, the search zone should be as small as possible, with all the
actual reference marks for all the products falling within the search zone. If the
printing tolerance is very tight, the search area can be made very small. If the
printing tolerance is not tight, then a bigger search area (and slower performance
during searching) will be required.
Setting Light Intensity
Light Intensity can be set to provide acceptable image appearance. Generally, if
the image appears acceptable to the human eye, the search algorithm will be able
to perform well. Currently, the recommended light intensity setting is 50%.
