PROBLEM TO BE SOLVED: To provide a compartment line detection device that achieves both of a wide detection range of a compartment line and reduced frequency of erroneous detection of the compartment line.SOLUTION: A compartment line detection device comprises a candidate extraction part 32 that extracts a candidate shape of a compartment line from an image, a prediction part 34 that calculates a prediction line of the compartment line at the present calculation time based on a detection line that is previously detected and a moving amount of a vehicle 70 from the detection time until the present calculation time, a range setting part 35 that sets a far range based on a distance from a camera corresponding to the vehicle 70 behavior such as changing an attitude of the on-vehicle camera 10 in a traveling direction as an exclusion range on the image, and sets a nearer range than the exclusion range as a detection range for detecting the compartment line, and a compartment line detection part 36 that decides, for each extracted candidate shape, conformity of the candidate shape and the prediction line by using a distance between the candidate shape and the prediction line in a longitudinal direction, and detects a compartment line based on the candidate shape having the conformity.SELECTED DRAWING: Figure 2

    【課題】区画線の検出範囲の広さと区画線の誤検出の抑制とを両立した区画線検出装置を提供する。【解決手段】画像から区画線の候補形状を抽出する候補抽出部32と、前回検出された検出線と、検出時から今回の演算時までの車両70の移動量とから、今回の演算時における前記区画線の予測線を算出する予測部34と、画像上で、走行方向において、車載カメラ10の姿勢を変化させるような車両70の挙動に応じたカメラからの距離を基準にして遠方の範囲を除外範囲とし、除外範囲よりも近傍側を、区画線を検出する検出範囲に設定する範囲設定部35と、設定された検出範囲において、抽出された候補形状ごとに、候補形状と予測線との横方向の距離を用いて候補形状と予測線との一致性を判定し、一致性を有する候補形状から区画線を検出する区画線検出部36と、を備える。【選択図】図2
