To improve accuracy in detecting a detection object.SOLUTION: An object detection device relating to an embodiment is an object detection device which detects detection objects from an image captured by a camera. A control unit divides the image into a plurality of areas on the basis of distribution information generated by using a plurality of images from which a distribution state of appearance positions within the image is preliminarily acquired for each of sizes of the detection objects, and sets thresholds for inference results of a learning model trained on feature quantities of the detection objects, to each of the plurality of divided areas.SELECTED DRAWING: Figure 4
【課題】検知対象物の検知精度を向上させること。【解決手段】実施形態に係る物体検知装置は、カメラによって撮影された画像から検知対象物を検知する物体検知装置であって、制御部は、検知対象物のサイズ毎に画像内における出現位置の分布状況を予め取得した複数の画像を用いて生成した分布情報に基づき、画像を複数の領域へ分割し、検知対象物の特徴量を学習した学習モデルの推論結果に対する閾値を分割した複数の領域それぞれに設定する。【選択図】図4
