To alleviate a processing load about recognition of a vehicle location.SOLUTION: A location recognition device recognizing a location of a vehicle comprises: a location estimation unit that calculates an estimation location of the vehicle on the basis of positioning; a map characteristic point extraction unit that sets a first map range containing the estimation location to map information, extracts a map characteristic point from the first map range, sets a second map range expanding the first map range to the map information when the number of extracted map characteristic points is less than a prescribed threshold, and extracts the map characteristic point from the second map range; an image characteristic point extraction unit that extracts an image characteristic point from a periphery image serving as an image photographing the periphery of the vehicle; and a location correction unit that collates the extracted map characteristic point with the image characteristic point to correct the estimation location, and calculates a post-corrected location of the vehicle.SELECTED DRAWING: Figure 1

    【課題】車両位置の認識に関する処理負荷を軽減する。【解決手段】車両の位置を認識する位置認識装置は、測位に基づいて車両の推定位置を算出する位置推定部と、地図情報に推定位置を包含する第1の地図範囲を設定し、第1の地図範囲から地図特徴点を抽出し、抽出した地図特徴点の数が所定の閾値未満である場合、地図情報に第1の地図範囲を拡張した第2の地図範囲を設定し、第2の地図範囲から地図特徴点を抽出する地図特徴点抽出部と、車両の周囲を撮影した画像である周囲画像から画像特徴点を抽出する画像特徴点抽出部と、抽出された地図特徴点と画像特徴点とを照合して推定位置を補正し、車両の補正後位置を算出する位置補正部とを備える。【選択図】図1
