PROBLEM TO BE SOLVED: To provide means that determines a true vehicle body color of a vehicle reflected in a shot image without requiring an advance registry of data about an individual vehicle.SOLUTION: Shot image acquisition means 11 of a vehicle body color determination device 1 is configured to acquire a shot image from a fixed-point camera installed in a road. License number plate color determination means 14 is configured to compare color information on the license number plate in the shot image with a prescribed threshold to determine a paint color of the license number plate reflected in the shot image. Vehicle body color determination means 15 is configured to determine a boundary value partitioning color space into a plurality of pieces of a color gamut, using a calculation expression in accordance with the paint color of the license number plate determined by the license number plate color determination means 14, and determine which any of pieces of the color gamut the color information on the vehicle body reflected in the shot image belongs to.SELECTED DRAWING: Figure 2

    【課題】個々の車両に関するデータの事前登録を要することなく、撮像画像に映った車両の真の車体色を特定する手段を提供する。【解決手段】車体色特定装置1の撮像画像取得手段11は道路に設置された定点カメラから撮像画像を取得する。ナンバープレート色特定手段14は撮像画像に映っているナンバープレートの塗色を、撮像画像におけるナンバープレートの色情報を所定の閾値と比較することにより特定する。車体色特定手段15はナンバープレート色特定手段14が特定したナンバープレートの塗色に応じた算出式に従い色空間を複数の色域に区分する境界値を特定し、撮像画像に映った車体の色情報がそれらの色域のいずれに属するかを特定する。【選択図】図2
