Overlap Tool l The camera, robot, and conveyor belt are calibrated. l The connection to the Adept SmartController is active. l The tool is receiving latched values from the input tool. The latch must be wired to the controller and properly configured. l The conveyor belt and the controller have been correctly assigned to a camera, in the ACE Sight vision project. l A valid Conveyor Tracking License is in place. Order of the Overlap Tool in an ACE Sight Sequence The Overlap Tool should be placed near the beginning of a sequence, just after the input tool, and before any inspection tools in the sequence.
This ensures that the same instance is not processed multiple times by the inspection tools. Basic Steps for Configuring the Overlap Tool 1. Select the tool that will provide the input. This can be any tool that returns a transform value. 2. Select the Distance parameter. This specifies how far an instance must be from the expected location of a known instance, in a different image, for it to be considered a new instance. Distance is spe- cified in mm. It should be as small as possible without causing double-picks. 5 mm is a recommended starting value for Distance.
l If Distance is too large, nearby instances will be interpreted as duplicates of a dif- ferent instance, and some will not be picked. l If Distance is too small, two transforms will be interpreted as different instances, and the system will try to double-pick the object. NOTE : Rotation is ignored by the Overlap Tool. Only the difference in XY is considered. 3. Test the Overlap Tool by executing the sequence and verifying results. Input The Input required by the Overlap Tool can be provided by any tool that returns a transform instance. ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 620
