| Abstract(in English) | Road marking inspection has been carried out by visual observation from the vehicle. However, visual inspection of large-scale road network by management staffs is high-cost. Therefore, in this study, we propose a method of detecting damage from the road images in low-cost. In our study, we picked up lane markings as a road marking and collects a number of images that shoot the road surfaces. Then, we dealt with those road images as a graph consisted of image as a node and similarity between images as an edge. In a few nodes, we put labels which denote “damaged” or “not damaged.” Finally we execute label propagation, all labels of nodes are estimated.Thus we got the estimation results with the accuracy rate over 85% from only 1.8% of already known correct labels. |
