Smart Infrared Inspection System Field Operational Test - Center for ...

• ROI Misidentified – As in this photo, the system may misinterpret the image
and identify the regions incorrectly. In this example, the tire region is
identified as the rim and the brake region is identified as around the hub. In
this case, any alerts would most likely be incorrect.
• No ROI Identified – If the wheel image is not fully in the frame or if the
image is significantly out of focus, SIRIS may not be able to identify any of
the regions. The system will mark the image as ‘Nothing Detected’ as in the
example on Page 8.
• Skewed ROI - Out of focus images may also result in a skewed ROI. In some
cases, the ROI is not centered on the wheel but is still covering a majority of it.
In this case, the thermal data is usable and correct.
