To provide a vehicle position detection device capable of easily and correctly estimating a position of a vehicle body (vehicle) from image information and correctly detecting the position of the vehicle on a world coordinate system.SOLUTION: A vehicle position detection device includes an acquisition section, an estimation section, and a processing section. The acquisition section acquires image information from an imaging section for imaging a detection object area. The estimation section estimates a correspondence position of a vehicle bottom surface of an estimation vehicle corresponding to a position of a reference point based on comparison between a learnt model obtained as a result of learning a relation between a learning vehicle included in the image information and at least one reference point indicating a reference position included in a vehicle bottom surface of the learning vehicle, and the estimation vehicle included in the image information acquired by the acquisition section. The processing section converts the correspondence position into a world coordinate system so as to detect the position of the estimation vehicle on the world coordinate system.SELECTED DRAWING: Figure 2
【課題】画像情報から車体(車両)の位置をより容易かつ正確に推定して、世界座標系上で正確に車両の位置を検出することができる、車両位置検出装置を提供する。【解決手段】本開示の一例としての車両位置検出装置は、取得部と、推定部と、処理部とを含む。取得部は、検出対象領域を撮像する撮像部から画像情報を取得する。推定部は、画像情報に含まれる学習用車両と当該学習用車両の車両底面に含まれる参照位置を示す少なくとも一つの参照点との関係を学習した結果としての学習済モデルと、取得部が取得した画像情報に含まれる推定用車両との比較に基づき、参照点の位置に対応する推定用車両の車両底面の対応位置を推定する。処理部は、対応位置を世界座標系に変換して、推定用車両の位置を世界座標系上で検出する。【選択図】図2
