In this research project, a method based on computational intelligence is used to differentiate the edge of a patch repair and a crackįrom digital images. Managers of road authorities can confidently use this technology. Method to separat e a patch boundary from a crack so that asset It is therefore important to establish a reliable
Repair as a crack, the diagnosis could lead to a significant amount Pavement image processing wrongly diagnoses the edge of a patch Overestimation of cracks caused by the detection of surface irregularities as cracks can cause erroneous prioritization and inefficient use of Since pavement management decisions are based on crack evaluation results, the Total road network, are highly patched, trenched, or both. Techniques have been developed andĪpplied with varying degrees of success for accurate detection andĭistinguishing cracks from patch boundaries has significant consequences since urban roads, which account for more than 90% of the Patch repair and the original road, since both cracks and boundaries Is accurate differentiation of cracks from the boundaries between a In other words, the technology has yet to
Until now, crack detection by automated imaging technology is oneĪrea in which reservations continue to exist among engineers, asset Consequently, laser- and imagebased surface condition monitoring has been employed to detectĪnd measure surface distresses such as cracks, texture, and ruttingĪnd has also been applied to the measurement of the road profile. The method is also gaining popularity in the civil engineering community and a significant amount of work has been Vision cameras are two well-known examples.ĭigital image processing for defect detection and condition monitoring is a popular tool and an established method in qualityĮngineering.
