To make it possible to detect deceleration of a preceding vehicle without depending on detection of lighting of a brake lamp of the preceding vehicle in a vehicle on which a monocular camera is mounted.SOLUTION: A device detects a preceding vehicle 4 and white broken lines 6L, 6R provided at equal intervals along a road 2 from an image captured by a monocular camera. The device acquires speed information of an own vehicle. The device counts the number of the white broken lines 6L, 6R included in a section from a longitudinal position y1 of the preceding vehicle 4 to a fixed reference position y2 below the longitudinal position y1 in a camera image, and detects deceleration of the preceding vehicle 4 based on time-series transition of the number of the white broken lines 6L, 6R and the speed information of the own vehicle.SELECTED DRAWING: Figure 1

    【課題】単眼カメラが搭載された車両において、先行車両のブレーキランプの点灯の検出に頼らず先行車両の減速を検知することを可能にする。【解決手段】本開示の装置は、単眼カメラで撮影された画像から、先行車両4と、道路2に沿って等間隔に設けられた白破線6L、6Rを検出する。また、本開示の装置は、自車両の速度情報を取得する。そして、本開示の装置は、カメラ画像内での先行車両4の縦方向位置y1から縦方向位置y1の下方の固定基準位置y2までの区間に含まれる白破線6L、6Rの個数をカウントし、白破線6L、6Rの個数の時系列推移と自車両の速度情報とに基づいて先行車両4の減速を検知する。【選択図】図1
