Automatic Road Pavement Assessment with Image Processing: Review and Comparison
Figure 5
The acquisition system used for the evaluation. In (a), the acquisition system is illustrated whereas in (b) it shows the user interface. In (c, d), an example of the final images is given. In (d), we can see the road that is visible in (c). The processing is done 1 meter by 1 meter, that is, independently on each image presented in (d). The surface contains two reparations of vertical cracks. In some cases, the 3 sensors do not have the same settings, and the global illuminations are different, so it can generate some “false cracks”. This aspect has been easily taken into account in a preprocessing step by eliminating the junction area in the region of interest.
