Description

本発明は色測定装置に関し、特に植物の葉等の色解析を行うための色測定装置に関するものである。   The present invention relates to a color measurement device, and more particularly to a color measurement device for performing color analysis of plant leaves and the like.

バイオテクノロジの進展に伴って、植物の葉等の色解析を行うための色測定装置が必要であるが、色測定装置の例としては、積分球を用いたもの(特許文献1,2参照)、0/45光学系(測定光を被測定物に対して直角(0度)に照射して、その拡散光を、照射光に対して45度に設置した受光素子により検出するようにした光学系)などが広く知られている。また、植物の植生状態の解析を行うための技術が特許文献3に開示されている。   With the progress of biotechnology, a color measuring device for color analysis of plant leaves and the like is necessary. As an example of the color measuring device, an integrating sphere is used (see Patent Documents 1 and 2). , 0/45 optical system (optical that irradiates measurement light at right angles (0 degrees) to the object to be measured and detects the diffused light by a light receiving element installed at 45 degrees with respect to the irradiation light. Etc.) are widely known. Further, Patent Document 3 discloses a technique for analyzing the vegetation state of a plant.

植物の葉を被測定物とした場合、上述した特許文献1,2に開示の積分球を用いた装置や、0/45光学系を用いた装置では、植物の葉を採取して、研究室や実験室に設置されているこれら装置に、採取した葉を取り込んで測定を行うことが必要である。しかしながら、植物が現に植生している状態で(葉を植物から切り離すことなく)、葉などの色測定を行う要求がある。   When plant leaves are used as objects to be measured, the apparatus using the integrating sphere disclosed in Patent Documents 1 and 2 described above or the apparatus using the 0/45 optical system collects plant leaves, It is necessary to take the collected leaves and perform measurement in these devices installed in the laboratory. However, there is a need to measure the color of leaves and the like while the plant is actually vegetated (without separating the leaves from the plant).

なお、特許文献3では、植物の植生状態の解析を行う技術が開示されているが、この技術では、上空から撮影した画像に基づき色の解析を行うものであり、現地において、植物の葉について、個々に色測定を行うことはできない。   In Patent Document 3, a technique for analyzing the vegetation state of a plant is disclosed. However, in this technique, color analysis is performed based on an image photographed from the sky. Individual color measurements cannot be made.

本発明の目的は、植物の葉などの色測定に際して、被測定対象である葉を切り取ったり、また植物を傷つけたりすることなく、現状のままで測定することが可能な色測定装置を提供することである。   An object of the present invention is to provide a color measuring device capable of measuring a color of a plant leaf or the like as it is without cutting a leaf to be measured or damaging the plant. That is.

本発明による色測定装置は、被測定物の色測定を行う色測定装置であって、被測定物に光を照射する第一の光源、及び前記被測定物からの拡散光を取出す取出口が取付けられた第一の部材と、前記被測定物を載置する第二の部材と、前記第二の部材に取付けられて前記被測定物に対して光を照射する第二の光源とを含み、前記第一及び第二の部材により前記被測定物を挟むことにより、前記第一及び第二の光源により前記被測定物の表裏両面から光を照射して前記被測定物の色測定をなすようにしたことを特徴とする。
The color measuring device according to the present invention is a color measuring device for measuring the color of an object to be measured, and includes a first light source for irradiating light to the object to be measured and an outlet for taking out diffused light from the object to be measured. A first member attached; a second member for placing the object to be measured; and a second light source attached to the second member for irradiating the object to be measured. Then, by sandwiching the object to be measured by the first and second members, the first and second light sources irradiate light from both the front and back surfaces of the object to be measured, thereby measuring the color of the object to be measured. It is characterized by doing so.

そして、前記第一の部材に取付けられた光源の光量に対する前記第二の部材に取付けられた光源の光量の割合は、約20〜60%の範囲に設定されていることを特徴とする。 Then, the ratio of light amount of the light source attached to said second member with respect to the light quantity of the light source attached to said first member, characterized in that it is set in a range of 20-60%.

前記第一及び第二の部材を開閉自在に連結する連結部材と、前記第一及び第二の部材が前記連結部材により閉状態になった時に、これら第一及び第二の部材間において測定空間を確定するための測定空間区画部とを含むことを特徴とする。   A connecting member for opening and closing the first and second members and a measurement space between the first and second members when the first and second members are closed by the connecting member. And a measurement space section for determining

更に、前記被測定物と前記測定空間区画部との接触部から漏れ入った外光の影響を補正する手段を含むことを特徴とし、前記手段は、前記光源オン時の前記取出口からの出力に対して、前記光源オフ時のそれを用いて前記影響を補正するようにしたことを特徴とする。また、前記手段は、前記光源オン時の前記取出口からの出力を検出する第一の手段と、前記光源オフ時の前記取出口からの出力を検出する第二の手段と、前記第一の手段による検出出力から前記第二の手段による検出出力を差し引く手段とを含むことを特徴としている。   And a means for correcting an influence of external light leaking from a contact portion between the object to be measured and the measurement space section, and the means is an output from the outlet when the light source is turned on. On the other hand, the influence is corrected by using that when the light source is off. Further, the means includes a first means for detecting an output from the outlet when the light source is on, a second means for detecting an output from the outlet when the light source is off, and the first Means for subtracting the detection output of the second means from the detection output of the means.

本発明の作用を述べる。被測定物に光を照射する光源及び被測定物からの拡散光を取出す取出口が取付けられた第一の部材と、被測定物を載置する第二の部材とを設け、これら両部材により被測定物を挟むことにより、被測定物の色測定をなすようにしている。この場合、両部材を連結部材によって互いに開閉自在に連結する構成としておき、第二の部材に葉などの被測定物を載置して、第一の部材を閉状態とした時に、両部材間において測定空間を確定するための測定空間区画部を設けておく。   The operation of the present invention will be described. A first member having a light source for irradiating light to the object to be measured and an outlet for taking out diffused light from the object to be measured, and a second member for placing the object to be measured are provided. The color of the object to be measured is measured by sandwiching the object to be measured. In this case, when both members are connected to each other by a connecting member so as to be openable and closable, when an object to be measured such as a leaf is placed on the second member and the first member is in a closed state, A measurement space section for determining the measurement space is provided.

このとき、測定空間区画部と被測定物との接触部には、隙間が生じるために外部からの光の漏れは避けられいなので、この外光の影響を補正する機能を設けるものである。こうすることにより、植物の葉などの色測定に際して、被測定対象である葉を切り取ったり、また植物を傷つけたりすることなく、現状のままで測定することが可能となる。   At this time, since a gap is formed at the contact portion between the measurement space section and the object to be measured, it is inevitable that light leaks from the outside. Therefore, a function for correcting the influence of this external light is provided. In this way, when measuring the color of a plant leaf or the like, it is possible to perform measurement as it is without cutting off the leaf to be measured or damaging the plant.

更に、第一の部材に取付けた光源の他に、第二の部材にも他の光源を取付けて、被測定物の表裏両面から光を照射する。自然界では、葉などの被測定物には照射光の他に、裏面からの透過光も存在するものであるから、より自然に近い、すなわち目視による測定条件に近い環境を作り出すために、当該他の光源を設けて、被測定物の透過光をも考慮した色測定をなすようにしている。   Further, in addition to the light source attached to the first member, another light source is attached to the second member, and light is irradiated from both the front and back surfaces of the object to be measured. In nature, the measured object, such as a leaf, also contains transmitted light from the backside in addition to the irradiation light. Therefore, in order to create an environment that is more natural, that is, close to the visual measurement conditions, The light source is provided to perform color measurement in consideration of the transmitted light of the object to be measured.

本発明によれば、被測定物を挟み込むようにして、色測定を行う構成としたので、被測定対象である葉などを切り取ったり、また植物を傷つけたりすることなく、現状のままで測定することが可能となるという効果がある。また、被測定物との接触部から漏れ入った外光の影響を補正するような機能をも付加することにより、正確な色測定が可能となるという効果がある。更には、被測定物の裏面から光を照射することにより、透過光をも考慮した正確な色測定ができるという効果もある。   According to the present invention, since the color measurement is performed so as to sandwich the object to be measured, the measurement is performed as it is without cutting off the leaf to be measured or damaging the plant. There is an effect that it becomes possible. Further, by adding a function for correcting the influence of external light leaking from the contact portion with the object to be measured, there is an effect that accurate color measurement can be performed. Furthermore, by irradiating light from the back surface of the object to be measured, there is an effect that accurate color measurement can be performed in consideration of transmitted light.

本発明の実施の形態について図面を参照しつつ詳細に説明する。図1及び図2は本発明の一実施の形態を示す正面図であり、図3はその側面図である。図1は被測定物である葉8を載置する載置部1と蓋部2とが開状態の場合の図であり、図2は閉状態の場合の図である。また、図4は、図2の状態において、蓋部2を透視して上面から見た図であり、これ等図1〜図4において、同等部分は同一符号にて示している。   Embodiments of the present invention will be described in detail with reference to the drawings. 1 and 2 are front views showing an embodiment of the present invention, and FIG. 3 is a side view thereof. FIG. 1 is a diagram in the case where the placement unit 1 and the lid 2 on which the leaf 8 to be measured is placed, and FIG. 2 is a diagram in the closed state. Further, FIG. 4 is a view seen from the top through the lid portion 2 in the state of FIG. 2. In these FIGS. 1 to 4, equivalent parts are denoted by the same reference numerals.

これ等図を参照すると、載置部1上には被測定物である葉8が載置される。載置部1と蓋部2とは、ヒンジ機構3により、開閉自在に連結されている。この蓋部2には、葉8へ、一定の分光特性と光量とを有する光を照射する測定用光源6と、葉8からの拡散光を検出する拡散光取出口7とが取付けられている。測定用光源6は葉8に対して直角に光を照射し、拡散光取出口7はこの測定用光源6に対して45度の角度をもって、蓋部2に形成されており、いわゆる0/45光学系を構成している。なお、5は測定用光源取付孔を示す。   Referring to these drawings, a leaf 8 as an object to be measured is placed on the placement portion 1. The placing portion 1 and the lid portion 2 are connected to each other by a hinge mechanism 3 so as to be freely opened and closed. The lid 2 is provided with a measurement light source 6 for irradiating the leaf 8 with light having a predetermined spectral characteristic and light amount, and a diffused light outlet 7 for detecting diffused light from the leaf 8. . The measurement light source 6 irradiates light at right angles to the leaf 8, and the diffused light outlet 7 is formed in the lid portion 2 at an angle of 45 degrees with respect to the measurement light source 6, so-called 0/45. An optical system is configured. Reference numeral 5 denotes a measurement light source mounting hole.

図2に示す様に、載置部1と蓋部2を閉状態としたときに、葉8の色測定のための測定空間を確定するために、蓋部2には、測定空間区画部4が取付けられており、植物20の葉8を載置部1上に載置して、蓋部2をヒンジ3を中心に回動させることにより、葉8を載置部1と蓋部2とにより挟み込むようにする。このとき、葉8の上面と測定空間区画部4とによって、測定空間が形成されるので、測定用光源6をオンとして葉8へ測定光を照射することで、測定空間に拡散光が拡散することになる。この拡散光を拡散光取出口7から、光ファイバ(図示せず)を用いて取出し、図5に示す色測定機能部へ供給する構成となっている。   As shown in FIG. 2, when the mounting portion 1 and the lid portion 2 are in the closed state, the lid portion 2 includes a measurement space partition portion 4 in order to determine a measurement space for color measurement of the leaves 8. Is mounted, and the leaf 8 is placed on the placement portion 1 and the lid portion 2 is rotated about the hinge 3, whereby the leaf 8 is placed on the placement portion 1 and the lid portion 2. So that it can be pinched. At this time, since the measurement space is formed by the upper surface of the leaf 8 and the measurement space partition unit 4, the diffused light is diffused into the measurement space by irradiating the measurement light to the leaf 8 with the measurement light source 6 turned on. It will be. This diffused light is extracted from the diffused light outlet 7 using an optical fiber (not shown) and supplied to the color measuring function unit shown in FIG.

図5を参照すると、本発明の一実施の形態の機能ブロック図が示されており、図1〜図4と同等部分は同一符号にて示されている。図5において、200は測定空間であり、載置部1と、蓋部2と、測定空間区画部4とにより形成される空間であり、100がこの空間200を確定する部材1,2,4を一体として示したものである。この場合、被測定物8と測定空間区画部4や載置部1との接触部分から、外光10がこの測定空間200へ漏れ入ることは避けられない。図5では、これを漏れ外光9として示している。   Referring to FIG. 5, a functional block diagram of an embodiment of the present invention is shown, and the same parts as those in FIGS. In FIG. 5, reference numeral 200 denotes a measurement space, which is a space formed by the placement portion 1, the lid portion 2, and the measurement space partition portion 4, and 100 is a member 1, 2, 4 that defines this space 200. Is shown as a unit. In this case, it is inevitable that the external light 10 leaks into the measurement space 200 from the contact portion between the DUT 8 and the measurement space partitioning section 4 or the mounting section 1. In FIG. 5, this is shown as leakage outside light 9.

そこで、本発明においては、この漏れ外光9による影響を補正する機能をも付加している。すなわち、拡散光取出口7から図示せぬ光ファイバを経て導出された光は、測定用光源OFF(オフ)時の拡散光検出機能部11及び測定用光源ON(オン)時の拡散光検出機能部12へ入力され、これ等両拡散光検出機能部11,12の両検出出力は色測定値補正機能部13へ入力される。この色測定値補正機能部13からの補正出力は色測定値解釈機能部14へ供給されて、色測定がなされる。   Therefore, in the present invention, a function for correcting the influence of the leakage outside light 9 is also added. That is, the light derived from the diffused light outlet 7 through an optical fiber (not shown) is a diffused light detection function unit 11 when the measurement light source is OFF and a diffused light detection function when the measurement light source is ON. The two detection outputs of both the diffused light detection function units 11 and 12 are input to the color measurement value correction function unit 13. The correction output from the color measurement value correction function unit 13 is supplied to the color measurement value interpretation function unit 14 for color measurement.

かかる構成において、先ず、測定用光源6がオフのとき、測定空間200は被測定物8との接触面等から漏れ入った漏れ外光9に満たされている。この漏れ外光9は測定誤差となるために、測定空間を確定する部材100(載置部1、蓋部2、測定空間区画部4)によって、被測定物8の測定面側への外光10の漏れを抑止してはいるものの、完全にこれを抑止することは不可能である。このときの漏れ外光9の一部は拡散光取出口7から光ファイバにより取出され、測定用光源OFF時の拡散光検出機能部11へ入力され、その量が検出される。この検出された光量は、RGB(3原色)毎に検出されるものとする。   In such a configuration, first, when the measurement light source 6 is off, the measurement space 200 is filled with leaked outside light 9 that has leaked from the contact surface with the object 8 to be measured. Since this leaked extraneous light 9 becomes a measurement error, the extraneous light to the measurement surface side of the measurement object 8 is measured by the member 100 (the placement unit 1, the lid unit 2, the measurement space partition unit 4) that determines the measurement space. Although 10 leaks are suppressed, it is impossible to completely suppress them. A part of the leakage outside light 9 at this time is taken out from the diffused light outlet 7 by an optical fiber and inputted to the diffused light detection function unit 11 when the measurement light source is OFF, and the amount thereof is detected. The detected light quantity is detected for each of RGB (three primary colors).

次に、測定用光源6がオンの状態において、上記と同様の検出処理を行う。測定用光源6がオンのときには、測定空間200は、被測定対象8との接触面などから漏れた漏れ外光9と、測定用光源6からの光とが、被測定対象8によって拡散反射した拡散光に満たされている。   Next, in the state where the measurement light source 6 is on, the same detection process as described above is performed. When the measurement light source 6 is on, the measurement space 200 diffuses and reflects the outside light 9 leaking from the contact surface with the measurement target 8 and the light from the measurement light source 6 by the measurement target 8. Filled with diffuse light.

この漏れ外光9と拡散光の一部は、拡散光取出口7から取出されて、図示せぬ光ファイバを介して測定用光源ON時の拡散光検出機能部12へ入力され、その光量がRGB毎に検出される。   The leakage outside light 9 and part of the diffused light are taken out from the diffused light outlet 7 and input to the diffused light detection function unit 12 when the measurement light source is turned on via an optical fiber (not shown). Detected for each RGB.

色測定値補正機能部13では、測定用光源ON時の拡散光検出機能部12の検出値を、測定用光源OFF時の拡散光検出機能部11の検出値により、RGB毎に補正する。この補正方法としは、測定用光源ON時の拡散光検出値から、測定用光源OFF時の拡散光検出値を差引く、減算処理による方法を用いることができるが、統計処理による方法を用いることもできる。補正された測定値は、色測定値解釈機能部14へ入力される。この色測定値解釈機能部14は、例えば8色測定値解釈機能を有し、マンセル表色系やPCCS(Practical Color Coordinate System )のコードとRGB値の対応表などの色テーブルを参照して、色名や色コードなどの色情報を自動計算する機能を有している。   In the color measurement value correction function unit 13, the detection value of the diffused light detection function unit 12 when the measurement light source is turned on is corrected for each RGB by the detection value of the diffused light detection function unit 11 when the measurement light source is turned off. As this correction method, a subtracting method can be used to subtract the diffused light detection value when the measurement light source is OFF from the diffused light detection value when the measurement light source is ON. You can also. The corrected measurement value is input to the color measurement value interpretation function unit 14. The color measurement value interpretation function unit 14 has, for example, an 8-color measurement value interpretation function, and refers to a color table such as a Munsell color system or a PCCS (Practical Color Coordinate System) code and RGB value correspondence table. It has a function to automatically calculate color information such as color names and color codes.

図6は本発明の第二の実施の形態を示す正面図であり、図1〜図4と同等部分は同一符号にて示している。本例では、被測定物の裏面からも測定用の光を照射するようにしたものであり、そのために、載置部1にも、測定物に対して直角に光を照射する光源6’を取付けたものである。なお5’は光源取付孔を示している。こうすることにより、被測定物の光の透過光を検出できるので、被測定物の透過特性を考慮した、より正確な色測定が可能となる。   FIG. 6 is a front view showing a second embodiment of the present invention, and the same parts as those in FIGS. In this example, the measurement light is also emitted from the back surface of the object to be measured. For this purpose, the mounting unit 1 is also provided with a light source 6 ′ that emits light at a right angle to the object to be measured. It is attached. Reference numeral 5 'denotes a light source mounting hole. By doing so, the transmitted light of the light to be measured can be detected, so that more accurate color measurement can be performed in consideration of the transmission characteristics of the object to be measured.

図7は本発明の第三の実施の形態を示す図であり、(A)はその上面図、(B)は正面図である。図7において図6と同等部分は同一符号により示している。本例は、図6の例と同様に、被測定物8の両面から光を照射する構造であるが、被測定物8を上側部材2(図6の蓋部に相当)と下側部材1(図6の載置部に相当)とにより、直接挟み込んで測定を行うものである。この場合、両部材1,2は互いに上下にスライドするような連結部材(特に図示せず)により連結する構造とすることができるが、これに限定されない。   FIG. 7 is a view showing a third embodiment of the present invention, in which (A) is a top view and (B) is a front view. 7, the same parts as those in FIG. 6 are denoted by the same reference numerals. This example has a structure in which light is irradiated from both sides of the object to be measured 8 as in the example of FIG. 6, but the object to be measured 8 is composed of the upper member 2 (corresponding to the lid portion in FIG. 6) and the lower member 1. (Corresponding to the placement portion in FIG. 6), and measurement is performed by directly sandwiching. In this case, both the members 1 and 2 can be connected by a connecting member (not shown in particular) that slides up and down, but is not limited thereto.

図6及び図7の実施の形態においては、上側部材2の光源6からの光は被測定物で反射し、その拡散反射光のみ(正反射光は除去される)が、拡散光取出口7へ入射する。また、下側部材1の光源6’からの光は被測定物8を透過し、その透過拡散光のみ(拡散せずに透過する光は除去される)が、拡散光取出口7へ入射する。よって、拡散反射光と透過拡散光とが加算されて拡散光取出口7から導出されることから、被測定物の透過特性を考慮した測定条件となり得る。   6 and 7, the light from the light source 6 of the upper member 2 is reflected by the object to be measured, and only the diffusely reflected light (regularly reflected light is removed), but the diffused light outlet 7 Incident to Further, the light from the light source 6 ′ of the lower member 1 passes through the measurement object 8, and only the transmitted diffused light (the light transmitted without being diffused is removed) enters the diffused light outlet 7. . Therefore, since diffused reflected light and transmitted diffused light are added and derived from the diffused light extraction port 7, it can be a measurement condition that takes into account the transmission characteristics of the object to be measured.

特に、両光源の被測定物8近傍における照射光量の比は、目視による色測定時の測定条件に合致するように設定するのが良い。例としては、光源6の光量に対して光源6’の光量の割合は、約20〜60%の範囲が良好であり、最適には、約40%とするのが良い。なお、この目視測定条件の例としては、RHS(英国国立園芸協会)カラーチャートに提示されている。   In particular, the ratio of the amount of irradiation light in the vicinity of the measurement object 8 of both light sources is preferably set so as to match the measurement conditions at the time of visual color measurement. As an example, the ratio of the light amount of the light source 6 'to the light amount of the light source 6 is preferably in a range of about 20 to 60%, and optimally about 40%. An example of this visual measurement condition is presented in the RHS (British National Horticultural Society) color chart.

上記の実施の形態においては、拡散光取出口7に光ファイバを取付けているが、この取出口7に、直接光センサ(受光素子)を取付けて、電気信号として、外部へ導出するようにしても良い。また、測定対象として、植物の葉を用いているが、これに限定されるものではない。また、上記実施の形態においては、0/45光学系の構造を示しているが、測定用光源6と拡散光取出口7との位置を逆にして、いわゆる45/0光学系の構造を採用することもできることは勿論である。   In the above embodiment, an optical fiber is attached to the diffused light outlet 7. However, an optical sensor (light receiving element) is directly attached to the outlet 7 so that it is led out as an electrical signal. Also good. Moreover, although the leaf of a plant is used as a measuring object, it is not limited to this. In the above embodiment, the structure of the 0/45 optical system is shown, but the so-called 45/0 optical system structure is adopted by reversing the positions of the measurement light source 6 and the diffused light outlet 7. Of course, it can also be done.

図5に示した測定用空間200の外部に設けられている各機能部11〜14は、コンピュータ(情報処理装置)として構成し、予めプログラムとして動作手順を組込んでおくことにより、小型軽量化が可能となり、図1〜図3及び図6,7に示した被測定対象物を挟み込む機構部分と、このコンピュータとを、光ファイバ及び信号線(測定用光源のオンオフ制御用)により連結することで、携帯型の色測定装置が得られる。   Each of the functional units 11 to 14 provided outside the measurement space 200 shown in FIG. 5 is configured as a computer (information processing apparatus), and the operation procedure is incorporated as a program in advance, thereby reducing the size and weight. 1 to 3 and FIGS. 6, 7, and the mechanism part that sandwiches the object to be measured, and this computer are connected by an optical fiber and a signal line (for on / off control of the measurement light source). Thus, a portable color measuring device can be obtained.
