PLANT LEAF IMAGING APPARATUS USING NEAR INFRARED LIGHT, PLANT LEAF SPECIFIC COMPONENT RATIO ESTIMATION SYSTEM AND PLANT LEAF SPECIFIC COMPONENT ESTIMATION METHOD AND PROGRAM

To provide a plant leaf imaging apparatus and plant leaf specific component ratio estimation system which can prevent the influence of external light when irradiating a plant leaf with near infrared light to acquire an image thereof.SOLUTION: An apparatus in which a plant leaf is placed in a light shielding state and which images reflection light from the plant leaf by irradiation of the near infrared light with a camera module comprises: a plant leaf placement part which has such a semi-cylindrical shape that the top side is flat and both ends are closed; a storage part which is in contact with the plant leaf placement part and stores a light source part that emits the near infrared light and the camera module; a lid part which has an inner peripheral shape that is fit to the plant leaf placement part and shields light for the plant leaf when the plant leaf is placed on the plant leaf placement part; and an external connection terminal. An opening is provided on the center part of the top side. The camera module is arranged in the storage part so as to be apart by a distance set to the opening and includes a light shielding part which shields the near infrared light irradiated from the light source part. The light source part is arranged in the storage part so as to irradiate the plant leaf placed on the opening with the near infrared light.SELECTED DRAWING: Figure 2 【課題】近赤外光を植物葉に照射してその画像を取得する場合に外光の影響を防ぐことができる植物葉撮像装置、植物葉特定成分比率推定システムを提供する。【解決手段】植物葉を遮光状態で載置し近赤外光の照射による植物葉からの反射光をカメラモジュールにより撮像する装置であって、天辺が平坦で両端部が閉塞された半円筒形状からなる植物葉載置部と、この植物葉載置部と連接し内部に近赤外光を発光する光源部とカメラモジュールとを収容する収容部と、植物葉載置部に嵌め合う内面形状を有し植物葉を植物葉載置部に載置したときに植物葉を遮光する蓋部と、外部接続端子とを含み、天辺の中央部には開口部が設けられ、カメラモジュールは開口部に対して設定した距離を離間して収容部に配置され、かつ、光源部から照射される近赤外光を遮光する遮光部を有し、光源部は開口部に載置された植物葉に近赤外光を照射するように収容部に配置された構成からなる。【選択図】図２
