PROBLEM TO BE SOLVED: To provide a vehicle type discrimination device and a vehicle type discrimination method, which can provide various services by identifying a specific vehicle type by utilizing existing facilities.SOLUTION: A vehicle type discrimination device 103 comprises a storage unit 95, a detection unit 92, and a discrimination unit 95. The storage unit stores a specific vehicle type in a vehicle type classification of a vehicle in association with a reference image for each face as a discrimination reference for each of the plurality of faces of the vehicle. The detection unit detects a plurality of faces from a captured image captured by an image capturing device of the vehicle. The discrimination unit collates each of the plurality of faces detected by the detection unit with the reference image for each face to obtain a similarity degree indicating the degree of similarity with the reference image for each face, and performs weighting addition by multiplying the degree of similarity of each face by weighting coefficients to obtain a vehicle type similarity which is a degree of similarity for each type of vehicle, and discriminates a model of the captured vehicle based on the vehicle type similarity.SELECTED DRAWING: Figure 2
【課題】既存の設備を活用して車両の具体的な車種を特定することにより、種々のサービスを提供可能にする車種判別装置及び車種判別方法を提供する。【解決手段】車種判別装置103は、記憶部95と、検出部92と、判別部95とを備える。記憶部は、車両の車種区分の中の具体的な車種と、車両の複数の面のそれぞれの判定基準となる面ごとの基準画像とを対応付けて記憶する。検出部は、撮像装置が車両を撮像した撮像画像から複数の面を検出する。判別部は、検出部が検出した複数の面のそれぞれと面ごとの基準画像とを照合して面ごとに基準画像との類似度合を示す類似度を求め、面ごとの類似度に対して重み係数を乗じて重み付け加算を行うことにより車種ごとの類似度である車種類似度を求め、車種類似度に基づいて、撮像された車両の車種として判別する。【選択図】図2
