To determine a lane on which other vehicles travel even if a division line in the vicinity of the other vehicles does not appear in an image.SOLUTION: A driving lane determination device (10) determines a lane on which other vehicles existing in front of an own vehicle travel based on an image that imaged a front of the own vehicle (1). The driving lane determination device includes: calculation means (11) for calculating a ratio of a distance from an end of a road of one side on the left and right of other vehicles to other vehicles to a distance from an end of the other side on the left and right side of other vehicles in the image; acquisition means (12) for acquiring the number of lanes of the road; and determination means (13) for determining the lane on which other vehicles travel based on the calculated ratio and the number of lanes.SELECTED DRAWING: Figure 1
【課題】他車両近傍の区画線が画像に写っていなくとも他車両が走行する車線を判定する。【解決手段】走行車線判定装置(10)は、自車両(1)の前方を撮像した画像に基づいて、自車両の前方に存在する他車両が走行する車線を判定する走行車線判定装置である。当該走行車線判定装置は、画像における他車両の左右一方の側の道路の端部から他車両までの距離と、他車両の左右他方の側の道路の端部から他車両までの距離との比を算出する算出手段(11)と、道路の車線数を取得する取得手段(12)と、算出された比及び車線数に基づいて、他車両が走行する車線を判定する判定手段(13)と、を備える。【選択図】図1
