To provide a compartment line specification device capable of specifying a compartment line even at a condition where many flares may occur.SOLUTION: A compartment line specification device: extracts a paint candidate that is a candidate of road surface paint used for specification of a compartment line from a picked-up image obtained with a camera 1 (S102); determines whether or not the paint candidate has first to third flare characteristics (S103); specifies a vehicle compartment line using an interconnect line generated by connecting paint candidates that are component paint candidates whose integrated value exceeds a threshold (S104-S106); and sets a strict threshold to a flare paint candidate that is a paint candidate determined to have any one of the first to third flare characteristics compared with a paint candidate determined to have no flare characteristics.SELECTED DRAWING: Figure 2

    【課題】フレアが多く発生し得る状況であっても、区画線の特定が可能な区画線特定装置を提供する。【解決手段】区画線特定装置は、カメラ1によって得られた撮像画像において、区画線の特定に用いる路面ペイントの候補であるペイント候補を抽出するS102。区画線特定装置は、ペイント候補が第1〜第3のフレア特徴を有するか否かを判定するS103。区画線特定装置は、統合値がしきい値を超える区画ペイント候補であるペイント候補を接続し生成した接続線を用いて車両区画線を特定するS104〜S106。区画線特定装置は、フレア特徴を有しないと判定されたペイント候補と比較して、第1〜第3のフレア特徴のうちいずれかを有すると判定されたペイント候補であるフレアペイント候補について、しきい値を厳しく設定する。【選択図】図2
