2. Resize and move the ROI to surround the feature of interest. In the Demo example, the feature of interest is the
Banner logo as shown here. It is still red because the parameters need to be set.
NOTE: When running an Area inspection, the sensor finds objects only within the ROI.
3. Click the sensor name button to go to open the Area sensor parameters menu.
4.
Set sensor parameters.
• Adjust the Intensity Range. This is the range of grayscale values the sensor should look for. Use the eye
dropper on the left of the screen to select the target feature, then use the slider bar at the bottom of the
screen to fine tune the selection to set the intensity range.
•
Adjust the Area Range. The Area Range is used to set the size limits of a feature of interest. Use the slider
bar at the bottom of the display to select the range. As the range narrows, the highlighted area turns
yellow. Areas are measured by counting pixels. For example, a rectangular feature that is 100 pixels wide
by 200 pixels tall has an area of roughly 20,000 pixels. The screenshot indicates that the areas that are
white are now within range of the inspection.
1. Move the slider at the bottom of the screen to the to the desired area range. In the Demo example,
the Area Range is adjusted so that each letter is identified as a found object (indicated by the red
highlight and the blue +).
