To enable estimation of an installation state of an imaging device which images a traffic environment without requiring human work and traffic regulation.SOLUTION: A state estimation device 100 comprises: a first state estimation unit which estimates first feature amount data from input image data; a second state estimation unit which estimates second feature amount data from the input image data; a feature estimation unit which estimates an installation state parameter of an imaging device that images the input image data from data obtained by combining the first feature amount data and the second feature amount data with a state estimation model that has performed machine-learning so as to estimate the installation state parameter of the imaging device that images the input image data by using third teacher data having the image data obtained by imaging a traffic environment by the imaging device and correct answer value data of the installation state parameter of the imaging device that images the image data; and a diagnostic unit which diagnoses the installation state of the imaging device on the basis of the estimated installation state parameter.SELECTED DRAWING: Figure 8

    【課題】人的作業や交通規制を必要とすることなく、交通環境を撮像する撮像装置の設置状態の推定を可能にする。【解決手段】状態推定装置100は、入力した前記画像データから第1特徴量データを推定する第1状態推定部と、入力した画像データから第2特徴量データを推定する第2状態推定部と、撮像装置が交通環境を撮像した画像データと画像データを撮像した撮像装置の設置状態パラメータの正解値データとを有する第3教師データを用いて、入力された画像データを撮像した撮像装置の設置状態パラメータを推定するように機械学習した状態推定モデルで、第1特徴量データと第2特徴量データとを合成したデータから、入力した画像データを撮像した撮像装置の設置状態パラメータを推定する特徴推定部と、推定した設置状態パラメータに基づいて撮像装置の設置状態を診断する診断部と、を備える。【選択図】図8
