To provide an object position detection apparatus that calculates a position of an object in a real world with accuracy from an image captured by a road side monitor camera while suppressing false detection of the object even in a terrain with varying floor heights.SOLUTION: An object position detection apparatus acquires a coordinate transformation formula of an image region corresponding to a position in an image of an object from object information map data, transforms the position in the image of the object into a position of a real world coordinate, acquires restriction information of a size of an image region corresponding to the position in the image of the object and an object type and possibility information of the presence, determines whether or not the object is falsely detected, and externally distributes the position of the object not falsely detected in the real world coordinate.SELECTED DRAWING: Figure 1

    【課題】床面の高さが様々に変化する地形でも、物体の誤検出を抑制しつつ、路側監視カメラにより撮像された画像から、実世界における物体の位置を精度よく算出することができる物体位置検出装置を提供する。【解決手段】物体情報マップデータから、物体の画像内の位置に対応する画像領域の座標変換式を取得して、物体の画像内の位置を実世界座標の位置に変換し、物体情報マップデータから、物体の画像内の位置及び物体種別に対応する画像領域のサイズの制限情報及び存在の可能性情報を取得して、物体の誤検出の有無を判定し、誤検出が無い物体の実世界座標の位置を外部に配信する物体位置検出装置。【選択図】図1
