StatusStatus and error messages display as appropriate.8.8.4 Using the Locate ToolFollow these steps for an example Locate inspection to adjust for a target that moves in the field of view, allowing for the preciseplacement of the vision tools that follow the Locate tool.This procedure uses a Locate tool to determine the position of the vial. Using the vial position information, three Edge tools and twoMeasure tools determine the position of the stopper. The Locate tool is used to ensure that the Edge02 and Edge03 tools are placedcorrectly alongside (but not on top of) the vial, even if the vial targets move from side to side in the field of view from inspection toinspection. See Using the Edge and Measure Tools on page 94 for details on how to set up an Edge tool and a Measure tool.Note: This procedure is an example only.1. Add a Locate tool to the inspection.2. Adjust the ROI position, length, and width.a) Position the ROI horizontally across the side of the vial.b) Leave the ROI Width at the default (13 px).Figure 198. Locate ROI3. Find the edge that you want the tool to locate.a) Expand the Edge Profile parameters. Use the graph as a guide for the remaining steps.To make sure that you find the edge you want, observe how the Edge Profile graph changes as the Inputs change. Point to alocation on the graph—the corresponding location is the yellow line on the tool ROI displayed on the image. The horizontalgray line is the Threshold percent.b) Expand the Threshold parameters.c) Select Edge Strength from the Threshold Type list.d) Select Bright to Dark from the Edge Polarity list.e) Adjust the Edge Strength until only the desired edge is found. In this example it is 20.4. Expand Filters and set Smoothing to Smooth3 to filter out sharp changes in the edge profile.VE Series Smart Camera108 www.bannerengineering.com - Tel: 763.544.3164
