To detect an object with high accuracy compared to the prior art, even in a situation where a plurality of objects or structures are close to each other such that reflected waves interfere with each other.SOLUTION: An object position detection device of the present invention detects a position of an object based on a radar signal from a radar device. The object position detection device comprises a position estimation unit that estimates the presence/absence and a position of the object using a machine learning model learned from predetermined teacher image data representing the position of the object based on image data including the radar signal. Here, the image data is two-dimensional image data of a distance to the azimuth, or three-dimensional image data of the distance and relative velocity to the azimuth. Also, the teacher image data is represented by an object label, which is a figure composed of a plurality of pixels indicating the position of the object.SELECTED DRAWING: Figure 1

    【課題】従来技術に比較して、反射波が干渉するような近接する複数の物体又は構造物が近接する状況においても高精度で物体を検出する。【解決手段】本発明の物体位置検出装置は、レーダ装置からのレーダ信号に基づいて、物体の位置を検出する。物体位置検出装置は、レーダ信号を含む画像データに基づいて、物体の位置を表す所定の教師画像データにより学習された機械学習モデルを用いて、物体の有無及び位置を推定して、推定された物体の有無及び位置を表す画像データを出力する位置推定部を備える。ここで、画像データは、方位に対する距離の2次元画像データ、もしくは方位に対する距離及び相対速度の3次元画像データである。また、教師画像データは、物体の位置を示す複数の画素から構成された図形である物体ラベルで表わされる。【選択図】図1
