How to Improve the Accuracy of Mark Searches
If there are many areas on a workpiece that resemble a mark you saved, you can use the Area function of the
Template Match window to fine-tune how the camera evaluates these areas against the saved mark image. Doing
so increases the find-mark accuracy of the system.
NOTE: Advanced features for manipulating saved mark images to allow the system to find them faster and more
accurately are available in the optional OptiSure software add-on. Refer to “OptiSure Software Key” on page93
for the OptiSure kit part number. Refer to the OptiSure manual for operating instructions.
PREREQUISITES
The system is in the CCD Mode.
The mark you want to fine-tune is saved in the Mark Library.
