To provide a device and method for calculating the value of positioning difference between precision positioning information acquired by matching a facility object in a video and an object on precision map with each other and GNSS positioning information acquired on the basis of a global navigation satellite system (GNSS) and delivering distribution information that includes the calculated value of positioning difference to the surroundings via a communication network.SOLUTION: A distribution information generation method includes: acquiring video information that includes the image of a facility object obtained by photographing one or more facilities located in the surrounding of a road; acquiring precision positioning information for a video photographing position by matching a facility object in the acquired video information and an object on precision map with each other; and calculating the value of positioning difference between the precision positioning information at the video photographing position and GNSS positioning information of the video photographing position and distributing the result to the surroundings.EFFECT: It is possible for a terminal in the surrounding to improve the accuracy of positioning itself by correcting, utilizing the distributed value of positioning difference, the current positioning acquired on the basis of the GNSS.SELECTED DRAWING: Figure 9

    【課題】映像での施設物客体と精密地図の客体をマッチングさせて獲得した精密測位情報とGNSS(Global Navigation Satellite System)に基づいて獲得したGNSS測位情報間の測位差値を算出し、算出した測位差値を含む配布情報を通信網を介して周辺に配布する装置および方法を提供する。【解決手段】配布情報生成方法は、道路周辺に位置した一つ以上の施設物を撮影して得た施設物客体のイメージを含む映像情報を獲得し、獲得した映像情報での施設物客体と精密地図の客体をマッチングさせて映像撮影位置に対して精密測位情報を獲得し、映像撮影位置での精密測位情報と該当映像撮影位置のGNSS測位情報間の測位差値を算出してこれを周辺に配布する。【効果】周辺の端末機が配布された測位差値を利用してGNSSに基づいて獲得した現在測位を補正することによって、自分の測位正確度を向上することができる。【選択図】図9
