To provide a position estimation device capable of accurately estimating a position of a feature shown in an onboard image taken by a camera installed in a vehicle.SOLUTION: A position estimation device includes: a vehicle detection unit 41 that detects a first position of a vehicle 2, which has travelled over a predetermined road section, at a first time on the basis of a stationary sensor 3 installed on the predetermined road section or near the predetermined road section; a vehicle position estimation unit 42 that estimates a second position of the vehicle 2 at a second time, which is a time when an onboard image showing a predetermined feature is generated by an onboard camera 11 installed in the vehicle 2, on the basis of the first position of the vehicle 2 at the first time; and a feature position estimation unit 44 that estimates the position of the predetermined feature in a real space on the basis of the estimated second position.SELECTED DRAWING: Figure 5

    【課題】車両に搭載されたカメラにより得られた車載画像に表された地物の位置を正確に推定可能な位置推定装置を提供する。【解決手段】位置推定装置は、所定の道路区間上、または所定の道路区間の近傍に設置された固定センサ3に基づいて、第1の時刻における、所定の道路区間を走行した車両2の第1の位置を検出する車両検出部41と、第1の時刻における車両2の第1の位置に基づいて、所定の地物が表された車載画像が車両2に搭載された車載カメラ11により生成された生成された第2の時刻における車両2の第2の位置を推定する車両位置推定部42と、推定された第2の位置に基づいて実空間における所定の地物の位置を推定する地物位置推定部44とを有する。【選択図】図5
