PROBLEM TO BE SOLVED: To provide a map data creation device or the like which can decrease processing load when map data for road is created based on a plurality of images.SOLUTION: A map data distribution device comprises: an acquisition unit which acquires a plurality of images photographing the same section of a road; a generation unit generating linear information in which a plurality of features on the road included in the image are linearized with respect to each of a plurality of images; an extraction unit which extracts the linear information of the feature from each of images for each of the features; a comparison unit which compares each pieces of the extracted linear information for each of the features; a selection unit which selects the image that includes a lot of pieces of the linear information for each of the features on the basis of the comparison result by the comparison unit; and a synthesis unit which synthesizes the linear information included in the selected images for each of the features by the selection unit to create the feature data of the features on the road.SELECTED DRAWING: Figure 2
【課題】複数の画像から道路の地図データを作成する際の処理負荷を低減可能な地図データ作成装置等を提供する【解決手段】本発明の一実施形態に係る地図データ配信装置は、同一区間の道路を撮影した複数の画像を取得する取得部と、当該複数の画像の各々に対して、当該画像に含まれる当該道路上の複数の地物を線形化した、線形情報を生成する生成部と、当該複数の地物ごとに、当該複数の画像の各々から、当該地物の当該線形情報を抽出する抽出部と、当該複数の地物ごとに、抽出した当該線形情報の各々を比較する比較部と、当該比較部による比較の結果に基づいて、当該複数の地物ごとに、当該線形情報が多く含まれる画像を選択する選択部と、当該選択部が当該複数の地物ごとに選択した当該画像に含まれる当該線形情報を合成して、当該道路上の当該複数の地物の地物データを作成する合成部と、を備える。【選択図】図2
