To provide an object change detection system for updating a high-precision road map.SOLUTION: A system includes a change detection device 100_1 to 100_N which compares a road facility object of a road image captured with a camera fixed to a vehicle with a high-precision road map and detects a change of an object. The change detection device includes: a map information storage unit for receiving and storing a high-precision road map including an attribute of each road facility object and spatial coordinates of a feature point from a map update server; an object coordinate acquisition unit for recognizing the road facility object from the road image and acquiring the attribute of the recognized object and the spatial coordinates of the feature point; and a change object detection unit that mutually compares the attribute of the recognized object and the spatial coordinates of the feature point with an object of the high-precision road map and, when a change object is detected, transmits object change information including the attribute of the change object, the image and the spatial coordinates of the feature point to the map update server.SELECTED DRAWING: Figure 1

    【課題】高精度道路地図の更新のためのオブジェクト変化検知システムを提供する。【解決手段】車両に固定されたカメラで撮影された道路映像の道路施設物オブジェクトと高精度道路地図を比較して、オブジェクトの変化を検知する変化検知装置100_1〜100_Nを含むシステムであって、変化検知装置は、地図更新サーバから各道路施設物オブジェクトの属性と特徴点の空間座標を含む高精度道路地図を受信して保存する地図情報保存部と、道路映像から道路施設物オブジェクトを認識し、認識されたオブジェクトの属性と特徴点の空間座標を取得するオブジェクト座標取得部と、認識されたオブジェクトの属性及び特徴点の空間座標を高精度道路地図のオブジェクトと相互に比較して、変化オブジェクトが検知された場合、変化オブジェクトの属性、映像と特徴点の空間座標を含むオブジェクト変化情報を地図更新サーバへ伝送する変化オブジェクト探知部を含む。【選択図】図1
