Abstract:
(EN) A vehicle vision system is used to detect raindrops on a windshield. A raindrop candidate on a windshield is usually represented with an optical model as a convex lens formed from a section of a sphere. Said optical model is used to reconstruct the image of each raindrop from the scene in front of the vehicle viewed through the windshield. If there is significant correlation between the actual image of the raindrop candidate and the reconstructed raindrop image, the raindrop candidate is identified as an actual raindrop. The identification result can be used to start wipers or other apparatuses.
(FR) L'invention porte sur un système de vision de véhicule qui est utilisé pour détecter des gouttes de pluie sur un pare-brise. Une goutte de pluie candidate sur un pare-brise est habituellement représentée par un modèle optique sous la forme d'une lentille convexe formée à partir d'une section d'une sphère. Ledit modèle optique est utilisé pour reconstruire l'image de chaque goutte de pluie à partir de la scène devant le véhicule, visualisée à travers le pare-brise. S'il y a une corrélation significative entre l'image réelle de la goutte de pluie candidate et l'image de goutte de pluie reconstruite, la goutte de pluie candidate est identifiée comme étant une goutte de pluie réelle. Le résultat d'identification peut être utilisé pour démarrer les essuie-glaces ou d'autres appareils.
(JA)  車両用ビジョンシステムを利用してウインドシールド上の雨滴を検出する。ウインドシールド上の雨滴候補を、通常、球の一切片からなる凸レンズとしての光学モデルにより表す。この光学モデルを用いて、各雨滴の像を、ウインドシールドを透過する車両前方の景色から再構成する。雨滴候補の実際の像と再構成雨滴像との間の相関が高い場合には、雨滴候補が実際に雨滴であると同定することができる。同定結果は、ワイパ等の他の装置を起動するために利用することができる。
