To appropriately detect failures of a road without converting a series of images in which the road forward or rearward is photographed into an image looked upon from right above.SOLUTION: Provided is a road failure detection device 100, and that includes: a detection section 113 for, from a series of images based on perspective in which a road forward or rearward is photographed, detecting an image area including failures of the road; and a tallying section 116 for using a sum of an area of the detected image area, for calculating a failure ratio of the road for each section. In the failures, at least one of a crack and a hole is included.SELECTED DRAWING: Figure 1

    【課題】前方もしくは後方の道路を撮影した一連の画像を、真上から見た画像に変換することなく、道路の不具合を適切に検出する。【解決手段】道路不具合検出装置100であって、前方もしくは後方の道路を撮影した遠近法に基づく一連の画像から、道路の不具合を含む画素領域を検出する検出部113と、検出した前記画素領域の面積の合計を用いて、区間毎の道路の不具合率を算出する集計部116と、を有し、前記不具合には、ひび割れおよび穴の少なくとも1つを含む。【選択図】図1
