8.6.4 Using the Edge and Measure ToolsFollow these steps for an example Edge inspection to check the position of a plunger in a syringe.This procedure uses two Edge tools and a Measure tool to determine the position of the plunger in the barrel.Note: This procedure is an example only.1. Add an Edge tool to the inspection.2. Adjust the ROI position, length, and width.a) Position the ROI vertically over the top of the plunger.b) Expand ROI, then expand ROI Width.c) Set the ROI width to 161 px.Figure 161. ROI Over the Top of the Plunger3. Set the threshold.a) Expand the Threshold parameters.b) Set the Threshold Type to Edge Strength.c) Leave Edge Strength at the default (20).d) Select Bright to Dark from the Edge Polarity list.The tool finds the top of the plunger.4. Add a second Edge tool.5. Adjust the ROI position, length, and width.a) Position the ROI vertically over the top of the barrel.b) Expand ROI, then expand ROI Width.c) Set the ROI width to 97 px.Figure 162. ROI Over the Top of the Barrel6. Set the threshold.a) Expand the Threshold parameters.b) Set the Threshold Type to Edge Strength.c) Expand Edge Strength and set it to 21.d) Select Dark to Bright from the Edge Polarity list.The tool finds the lower edge of the barrel.VE Series Smart Camera94 www.bannerengineering.com - Tel: 763.544.3164
