Abstract
(EN) This road surface state estimating method is for estimating the state of a road surface on which a vehicle (100) travels, wherein an observation area (R1) of a road surface (10) is determined by using image information obtained by capturing an image of the road surface (10) with a camera (101), first road surface information about the observation area (R1) is acquired from the image information, second road surface information about the observation area (R1) is acquired from sensing information obtained by detecting the state of the road surface (10) with a road surface sensor (104), and the road surface state of the observation area (R1) is estimated on the basis of the first road surface information and the second road surface information.
(FR) Procédé d'évaluation de l'état d'un revêtement routier destiné à évaluer l'état d'un revêtement routier sur lequel se déplace un véhicule (100), une zone d'observation (R1) du revêtement routier (10) étant déterminée en utilisant des informations d'image obtenues par capture d'une image du revêtement routier (10) avec un appareil de prise de vues (101), des premières informations relatives au revêtement routier concernant la zone d'observation (R1) étant acquises à partir des informations d'image, des secondes informations relatives au revêtement routier concernant la zone d'observation (R1) étant acquises à partir d'informations de détection obtenues par détection de l'état du revêtement routier (10) à l'aide d'un capteur de revêtement routier (104), et l'état du revêtement routier de la zone d'observation (R1) étant évalué sur la base des premières et secondes informations relatives au revêtement routier
(JA) 路面状態推定方法は、車両(100)が走行する路面の状態を推定する路面状態推定方法であって、路面(10)をカメラ(101)で撮像して得られた画像情報を用いて、路面(10)の観測領域(R1)を決定し、画像情報から観測領域(R1)における第1の路面情報を取得し、路面(10)の状態を路面センサ(104)で検出して得られたセンシング情報から観測領域(R1)における第2の路面情報を取得し、第1の路面情報および第2の路面情報に基づいて観測領域(R1)の路面状態を推定する。
