To provide a section line detection technology capable of reducing such a situation that a target parking position is shifted from a correct position due to an influence of a vehicle parked in a parking section adjacent to a parking section including the target parking position.SOLUTION: A section line detection device comprises: a detection part for detecting first and second section lines from a camera photographic image; a position calculation part for calculating a target parking position between the first section line and the second section line; and an update part for updating the first section line to a first new section line. The update part is configured to, when the detection part detects the first new section line at a position across the first division line from the target parking position, and when a first angle made by a straight line connecting an endpoint corresponding to a vehicle side end of the first new division line to an endpoint corresponding to a vehicle side end of the second division line and the second division line is out of a predetermined range, not update the first division line to the first new division line.SELECTED DRAWING: Figure 1

    【課題】目標駐車位置を含む駐車区画に隣接する駐車区画に駐車されている車両の影響で目標駐車位置が正しい位置からずれることを低減できる区画線検出技術を提供する。【解決手段】区画線検出装置は、カメラ撮影画像から第1,2の区画線を検出する検出部と、第1の区画線及び第2の区画線の間に目標駐車位置を算出する位置算出部と、第1の区画線を第1の新たな区画線に更新する更新部と、を備える。更新部は、検出部が目標駐車位置から第1の区画線を跨いだ位置に第1の新たな区画線を検出した場合に、第1の新たな区画線の車両側の端部に対応する端点と第2の区画線の車両側の端部に対応する端点とを結ぶ直線と、第2の区画線とのなす第1の角が第1の所定範囲外であれば、第1の区画線を第1の新たな区画線に更新しない。【選択図】図1
