VEHICLE POSITION ESTIMATION SYSTEM, METHOD, AND PROGRAM

PROBLEM TO BE SOLVED: To provide a technique with which it is possible to improve the accuracy of estimating a vehicle position by an image.SOLUTION: A vehicle position estimation system of the present invention comprises: a by-camera estimated position acquisition unit for acquiring a first estimated position that is a vehicle position estimated on the basis of image recognition of a first image captured by a first onboard camera, and a second estimated position that is a vehicle position estimated on the basis of image recognition of a second image captured by a second onboard camera differing in optical axis from the first onboard camera; and a derived position acquisition unit for acquiring a derived position that is the position of the vehicle derived on the basis of the first estimated position and second estimated position, the reliability of the first estimated position, and the reliability of the second estimated position.SELECTED DRAWING: Figure 2 【課題】画像による車両の位置推定の精度を向上できる技術の提供。【解決手段】車両位置推定システムは、第１車載カメラにて撮像された第１画像の画像認識に基づいて推定した車両の位置である第１推定位置と、前記第１車載カメラと光軸方向が異なる第２車載カメラにて撮像された第２画像の画像認識に基づいて推定した車両の位置である第２推定位置とを取得するカメラ別推定位置取得部と、前記第１推定位置と前記第２推定位置、および、前記第１推定位置の信頼度と前記第２推定位置の信頼度に基づいて導出した前記車両の位置である導出位置を取得する導出位置取得部と、を備える。【選択図】図２
