Figure 61. Average Gray Tool—Test ParametersAverage GrayscaleThe grayscale value range.Standard DeviationThe standard deviation range.8.1.3 Average Gray Tool: ResultsTools & Results and All Results list information from the current and previous inspections.A red box around a tool indicates that the tool failed. Status provides information about the specific failure.All Results displays the Result, Time, Pass Count, and Fail Count information at a glance. Expand the inspection tool tosee specific results for that tool.Average GrayscaleThe average grayscale value of the pixels in the ROI.Standard DeviationThe standard deviation of the average grayscale value for the pixels in the ROI.Execution TimeThe execution time, in milliseconds, for the currently selected tool in the current inspection.Expand Execution Time to see the historical minimum and maximum execution times up to this point for theselected tool.Use the reset button in the Inspection Summary to reset these historical values.StatusStatus and error messages display as appropriate.8.1.4 Using the Average Gray ToolFollow these steps for a typical presence/absence Average Gray inspection.NOTE: This procedure is an example only.1. Add an Average Gray tool to the inspection.2. Adjust the ROI to frame the desired feature.3. Set the Test parameters to set the pass/fail criteria.a) On the Test tab, select the Average Grayscale checkbox.This option sets the grayscale range that must be present in the ROI so that a part passes.b) Move the sliders or enter the minimum and maximum grayscale. Inspections outside of this range will fail. For thisexample, the minimum is 56.12 and the maximum is 74.83.The green bar indicates the current grayscale and the light gray background indicates the grayscale over time sincethe last reset.VE Series Smart Camera52 www.bannerengineering.com - Tel: 763.544.3164
