PROBLEM TO BE SOLVED: To provide a syringe measuring system which can be easily carried without having an electric balance and an ascent/descent device.SOLUTION: A syringe 6 placed on a placing surface 17 of a placing table 14 is imaged with an image pickup device 19 while being illuminated from behind with diffusion light from a light-emitting surface 16 of an illumination device 15, an image of calibrations 6b of the syringe 6 is detected from the picked-up image by an information processing device 12, calibrations continuing portions A, C, in which the images of the calibrations are aligned with equal spaces, and a calibration omitted portion B in which the calibrations are omitted are recognized in images, and an estimated liquid amount value in the syringe is calculated on the basis of the number of the calibration images belonging to the calibrations continuing portion A on a needle attached portion 6a side. Data of the width of the calibration omitted portion B is compared with data of packing thickness t to recognize the propriety of the calculated value. The data of the space of the calibrations continuing portion A is compared with data of calibration marking intervals to recognize the syringe 6.COPYRIGHT: (C)2014,JPO&INPIT【課題】電子天秤や昇降装置が無くて携帯も容易なシリンジ計量システムを実現する。【解決手段】載置台14の載置面17に載せたシリンジ6を、照明装置15の発光面16からの拡散光で後方から照明しながら、撮像装置19で撮り、情報処理装置12によって、撮影画像からシリンジ6の目盛6bの画像を検出して、目盛画像が等間隔で並らんだ目盛連続部分A,Cと目盛画像が抜け落ちた目盛抜落部分Bとを画像認識し、針装着部6a側の目盛連続部分Aに属する目盛画像の数に基づいてシリンジ内の液量の推定値を算出する。目盛抜落部分Bの幅とパッキン厚tのデータ等との比較により算出値の適否を確認する。目盛連続部分Aの間隔と目盛間隔データとの比較によりシリンジ6を確認する。【選択図】 図1
