Abstract:
(EN) The purpose of the present invention is to provide a novel road information recognition system capable of highly accurately estimating the positions of lane markers (LM4) to be located on the far side of a lane (L3) after change of lane. The present invention is equipped with: a front lane marker detection means for detecting, by using a front imaging means, lane markers (LM3) located ahead (FF1) of a host vehicle; a side lane marker detection means for detecting, by using a side imaging means, the positions of lane marker (LM3, LM4) located on both sides (RR1) of the vehicle and a lane width (W); and a front lane marker estimation means for estimating the positions of the lane markers (LM4) to be located on the far side of the lane (L3) after change of lane on the basis of the information regarding the lane markers (LM3) located ahead (FF1) of the vehicle, which is obtained by the front lane marker detection means, and the positions of the lane markers (LM3, LM4) located on the sides (RR1) of the vehicle and the lane width (W), which are obtained by the side lane marker detection means.
(FR) La présente invention vise à proposer un nouveau système de reconnaissance d’informations de route apte à estimer de manière très précise les positions de balises de marquage de voie (LM4) à placer sur le côté éloigné d’une voie (L3) après un changement de voie. La présente invention est équipée de : un moyen de détection de balise de marquage de voie avant permettant de détecter, par l'utilisation d’un moyen d’imagerie avant, des balises de marquage de voie (LM3) placées devant (FF1) un véhicule hôte ; un moyen de détection de balise de marquage de voie latérale permettant de détecter, par l'utilisation d’un moyen d’imagerie latérale, les positions d’une balise de marquage de voie (LM3, LM4) placée sur les deux côtés (RR1) du véhicule et une largeur de voie (W) ; et un moyen d’estimation de balise de marquage de voie avant permettant d'estimer les positions des balises de marquage de voie (LM4) à placer sur le côté éloigné de la voie (L3) après un changement de voie sur la base des informations concernant les balises de marquage de voie (LM3) placées devant (FF1) le véhicule, qui sont obtenues par le moyen de détection de balise de marquage de voie avant, et les positions des balises de marquage de voie (LM3, LM4) placées sur les côtés (RR1) du véhicule et la largeur de voie (W), qui sont obtenues par le moyen de détection de balise de marquage de voie latérale.
(JA) 本発明は、変更後車線(L3)の遠方の車線マーカ位置(LM4)を精度よく推定することができる新規な道路情報認識システムを提供することにある。本発明は、前方撮像手段を用いて自車両の前方(FF1)の車線マーカ(LM3)を検出する前方車線マーカ検出手段と、側方撮像手段を用いて車両側方(RR1)の車線マーカの位置(LM3,LM4)および車線幅(W)を検知する側方車線マーカ検出手段と、前方車線マーカ検出手段によって取得した車両前方(FF1)の車線マーカの情報(LM3)と側方車線マーカ検出手段によって取得した車両側方(RR1)の車線マーカ(LM3,LM4)及び車線幅(W)に基づいて変更後車線(L3)の遠方の車線マーカ(LM4)を推定する前方車線マーカ推定手段を備えた。
