PROBLEM TO BE SOLVED: To provide a vehicle model discrimination device capable of accurately discriminating a vehicle model of a passing vehicle through the use of an existing camera that is used for road management, etc.SOLUTION: A vehicle model discrimination device includes a storage section, an acquisition section, a detection section, a first discrimination section, a second discrimination section, and an integrated discrimination section. The storage section stores a discrimination reference of a vehicle model of a vehicle. The acquisition section acquires captured images obtained by imaging a vehicle by an imaging apparatus. The detection section detects images of a vehicle from captured images. The first discrimination section discriminates a vehicle model of a vehicle on the basis of the first image of a vehicle detected from the first captured image captured by the imaging apparatus and the discrimination reference. The second discrimination section discriminates a vehicle model of a vehicle on the basis of the second image of a vehicle detected from the second captured image where a vehicle detected from the first captured image is imaged and the discrimination reference. The integrated discrimination section integrates a discrimination result of the first discrimination section with a discrimination result of the second discrimination section, so as to discriminate a vehicle model of a vehicle.SELECTED DRAWING: Figure 3
【課題】道路の管理等のために用いられる既設のカメラを用いて、通行する車両の車種を高精度に判別することができる車種判別装置を提供すること。【解決手段】本実施形態の車種判別装置は、記憶部と、取得部と、検出部と、第一の判別部と、第二の判別部と、統合判別部と、を備える。記憶部は、車両の車種の判別基準を記憶する。取得部は、撮像装置が車両を撮像した撮像画像を取得する。検出部は、撮像画像から車両の画像を検出する。第一の判別部は、撮像装置に撮像された第一の撮像画像から検出された車両の第一の画像と、判別基準とに基づいて、車両の車種を判別する。第二の判別部は、第一の撮像画像で検出された車両が撮像された第二の撮像画像から検出された車両の第二の画像と、判別基準とに基づいて、車両の車種を判別する。統合判別部は、第一の判別部の判別結果と、第二の判別部の判別結果とを統合し、車両の車種を判別する。【選択図】図3
