To accurately discriminate the state of a vehicle in a vehicle facility while specifying the vehicle to efficiently operate the vehicle facility.SOLUTION: A vehicle discrimination method according to an embodiment includes a generation step and a discrimination step. In the generation step, machine learning is executed such that regions relevant to the number and emblem of a vehicle in a captured image to be a positive example captured by a first camera provided per predetermined parking/stopping region in a vehicle facility are included at least in a feature vector to generate a state discrimination model of a parking/stopping region. In the discrimination step, on the basis of an output value obtained by inputting the captured image to be targeted for discrimination captured by the first camera to the state discrimination model, the number and emblem of the vehicle parked/stopped in the parking/stopping region are discriminated.SELECTED DRAWING: Figure 2B
【課題】車両施設における車両の状態を、車両を特定しつつ精度よく判別し、車両施設を効率よく運用すること。【解決手段】実施形態に係る車両判別方法は、生成工程と、判別工程とを含む。生成工程は、車両施設の所定の駐停車領域ごとに設けられた第1のカメラによって撮像された正例となる撮像画像における車両のナンバーおよびエンブレムの該当領域が少なくとも特徴ベクトルに含まれるように機械学習を実行することによって、駐停車領域の状態判別モデルを生成する。判別工程は、第1のカメラによって撮像された判別対象分となる撮像画像を状態判別モデルへ入力することによって得られる出力値に基づいて、駐停車領域に駐停車中の車両のナンバーおよびエンブレムを判別する。【選択図】図2B
