Automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. Most of the road detection approaches are based on image segmentation algorithms. Color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems.

Road surface irregularity is known to effect vehicle NVH responses. When modeling vehicle NVH, it is desirable to have high-resolution measurements of the road surface to use as road input. For typical NVH modal tire models, the road surface sampling rate will not be an issue because several points on the tire patch (center line) are used to determine the road surface irregularity. The single p...
