ROAD DAMAGE DETERMINATION DEVICE, ROAD DAMAGE DETERMINATION METHOD, AND ROAD DAMAGE DETERMINATION PROGRAM
To extend a life of total pavement with a low cost by determining the damage level of a road from an image obtained by photographing the road.SOLUTION: A road damage determination device 100 includes a dividing unit 151 for dividing a road image obtained by photographing the road into a plurality of partial images, and a determination unit 153 for determining the damage level of each of the partial images by using a learned model. The damage level is set on the basis of the number of node points indicating cross points of cracks, and the learned model is learned by using teacher data containing a damage level and images having the number of the node points in a range set to the damage level.SELECTED DRAWING: Figure 1
【課題】道路を撮影した画像から道路の損傷レベルを判定することで、安価な費用で舗装全体の寿命を延ばす。【解決手段】道路損傷判定装置100であって、道路を撮影した道路画像を複数の部分画像に分割する分割部151と、各部分画像の道路の損傷レベルを、学習済みモデルを用いて判定する判定部153とを有し、前記損傷レベルは、ひび割れの交点を示す結節点の数に基づいて設定され、前記学習済みモデルは、損傷レベルと、当該損傷レベルに設定された範囲の結節点の数を有する画像とを含む教師データを用いて学習される。【選択図】図１
