37th Conference on Tire Science and Technology @ Akron, Ohio [September 11-13, 2018]
The forces applied from the vehicle to the road are transferred through the tire contact patch. Its visual inspection using modern optical equipment and image processing is essential for objective tire performance assessment. Quantitative image-based analysis can be useful for the accurate determination of the tire footprint under various operating conditions. However, the ground truth of the related tire footprint contact area is often not available and depends on various factors, such as image contrast, focus, resolution, depth of field, etc. Therefore, very frequently, simplified empirical methods are used to estimate the contact area. In this work, we present a novel methodology to evaluate the quality of different segmentation methods used to extract tire footprints from various video sequences.
