Info

• 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. 42
If the ROI is too skewed, it will cover more of the surrounding truck or the road rather than the wheel. In this case, the data is not usable and any alerts should be disregarded. 43
