8.7.4 Using the Match ToolFollow these steps for an example Match inspection. The Match tool requires that a reference pattern be taught during setup.The Match tool uses two ROIs. The larger, green/red ROI is the Search ROI and defines the area that the sensor searchesfor the desired feature. This ROI cannot be rotated and it is always a square. The smaller, blue ROI is the Teach ROI. ThisROI is used to define the feature that the sensor is looking for.Before using the Match tool, teach the desired feature (reference pattern). While setting up a Match tool, it can be helpfulto slow the trigger rate or to set the trigger to external.NOTE: If the trigger is set to internal, there is a lag between when the TEACH occurs and when Vision Manageruses the taught feature to inspect the part(s). The time to teach the sensor is not included in the inspection timeon Tools & Results or All Results.NOTE: This procedure is an example only.1. Add a Match tool to the inspection.Note that the inspection fails and a warning displays until the reference pattern is taught.Figure 195. Match Tool Defaults2. Adjust the Teach ROI to frame the feature to be used as the reference pattern. In this case, the feature is the Bannerlogo.a) Expand Teach ROI and select the ellipse.b) Resize and rotate the ROI around the feature.VE Series Smart Camera104 www.bannerengineering.com - Tel: 763.544.3164
