【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】この発明は1台のカラーCCDカメラを用い柑橘類等の塊状青果物の多面を検出する塊状青果物のカメラ選別機に用いる間接照明型多面撮影装置に関するものである。 BACKGROUND OF THE INVENTION This invention relates to the indirect lighting type multi imaging device used in a camera sorter massive vegetables and fruits for detecting a multi bulk fruits or vegetables, such as citrus using one color CCD camera.

【0002】 [0002]

【従来の技術】近時、みかんの選果場などにおいて使用する塊状青果物の選別,検査方法としては、旧来の機械的選別に代わり塊状青果物をカラーCCDカメラで撮影し、工学的にこの撮像を画像処理して着色度,傷,形状等を計測し等級・階級を判別するようになって来ている。 BACKGROUND ART Recently, sorting of bulk fruit or vegetable to be used in such tangerine selection result field, as the test method, taking the place bulk fruits or vegetables with a color CCD camera to mechanical sorting of old, the engineered this imaging image processing to coloring degree, scratches, shape, etc. measures have become adapted to determine the grade-class. この場合、今までは、1台のカメラでは1場面しか撮影ができなかった。 In this case, until now, it could not be only one scene shot in one camera. また、塊状青果物では撮影時に使用される照明装置によりその結果が左右されることが多い。 Moreover, the result is often governed by the illumination device used during shooting in bulk fruits or vegetables. 即ち、柑橘類等の塊状青果物の表面には光沢を有するもの種々あり、これに直接照射の照明を当てると強い反射(ハレーション)が一部に生じる。 That is, there various ones having gloss agglomerate fruits or vegetables of the surface of citrus fruits etc., strong reflection when exposed to illumination of directly irradiated thereto (halation) occurs in a part. 現在の画像処理による選別方法では、この反射で生じた箇所の正確な判 The screening method according to the current image processing, accurate determine point caused by the reflecting
断は不可能でした。 Dan was not possible. そのため現状では直接照明を行いながら反射光を除去するために光学的偏向フィルタを光源及びカメラのレンズに装着し、更に多数の過大光源を配置し均等な照度を得るようにしている(例えば、実開平4−51610号後方参照)。 Therefore the optical deflection filter to remove reflected light while illuminating directly at present mounted on the light source and the camera lens, so as to obtain the uniform illumination further arranged a number of excessive light source (e.g., actual Laid-back reference No. 4-51610).

【0003】 [0003]

【発明が解決しようとする課題】しかし、塊状青果物などの球状物において1面(例えば平面又は側面)だけの撮影では周囲全域を撮ることはできず、周囲全域に亘る傷等を検出することはできず、多数面を撮るには複数台のカメラを備えねばならず装置が複雑化され、簡易に塊状面全域の着色度,傷,形状等を確実に検出し得なかった。 [SUMMARY OF THE INVENTION] However, it is not possible to take around the whole when taking pictures of only one side (e.g., plane or side) in the spherical object, such as a bulk fruits or vegetables, detecting scratches over the circumference throughout the can not, the device not must comprise a plurality of cameras to take multiple surfaces is complicated, the coloring degree of bulk surface throughout easily, scratches, could not be reliably detected shape. また、カメラ撮影に当たって塊状青果物に与える照明で、強い反射を与えないためにフィルタを装着する態様では、当然光量が落ちるために過大光源(多数の電球)の配置を要するものである。 Also, in illumination when the camera shooting give bulk fruits or vegetables in the manner of mounting the filter in order not to give a strong reflection, those requiring the placement of excessive light source (many bulbs) for course amount falls. 従って、光源を増せば照明に対する消費電力が大きく、且つ多数の電球が必要となり、電球交換の頻度が高く、メンテナンスが面倒となる等の欠陥を有する。 Accordingly, large power consumption for illumination if Maze light source, and a large number of bulbs is required, more frequent bulb replacement, maintenance has a defect such as a troublesome.

【0004】本発明は上記実情に鑑み、塊状青果物への照明を間接照明とし、且つ反射板を用い1台のカメラでも多面を簡易に撮影し得るようにし、上記課題を解決する塊状青果物のカメラ選別機に用いる間接照明型多面撮影装置を提供することを目的としたものである。 [0004] The present invention has been made in view of the above circumstances, the illumination of the bulk fruits or vegetables and indirect lighting, and the polygon in a single camera using a reflection plate is adapted to be taken in a simple, massive fruit or vegetable to solve the above problems camera it is intended to provide an indirect illumination type multi imaging apparatus for use in sorting machines.

【0014】従って、この様に間接照明型多面撮影装置11は1台のカラーCCDカメラ6で多面の撮像を得る簡略構成となるため、塊状青果物Aにおける多面の着色度,傷,形状等を計測することができる。 [0014] Thus, such indirect illumination type multi imaging apparatus 11 for a simplified configuration to obtain the imaging polygon with a single color CCD camera 6, measuring the degree of coloring polygon in bulk vegetables and fruits A, scratches, shape, etc. can do.

【0015】 [0015]

【発明の効果】上述のように、本発明の塊状青果物のカメラ選別機に用いる間接照明型多面撮影装置は、装置本体を反射壁面付き筐体型とし且つ照明用光源を反射光の照射とする間接照明とし、しかも、カラーCCDカメラを1台とし、この撮影視野ないとなる搬送コンベアの両側に複数個の多面撮影用反射板を設けたため、搬送コンベアで搬入された塊状青果物の平面から側面に至る広範囲(ほぼ全面)な撮影だできる。 According to the present invention as described above, the indirect lighting type multi imaging device used in a camera sorter bulk fruits or vegetables of the present invention, the indirect to the and illumination light source to the apparatus main body and wall surfaces with housing integrated with the irradiation of the reflected light and lighting, moreover, the one color CCD camera, for providing a plurality of multi imaging reflector on both sides of the conveyor to be the no field of view, leads to side from the plane of the loaded bulk fruits or vegetables with conveyor wide range can'm (almost the entire surface) shooting. 即ち、所謂多面同時撮影が可能となり、この多面の撮像ををもって画像処理を行うため、塊状青果物にあっての広範囲な測定ができる。 That enables a so-called multiple simultaneous capturing and imaging of this multifaceted with a for image processing, it is extensive measurements which are in the bulk fruit or vegetable. しかも、この場合照明手段を塊状青果物に直接照射をしない筐体内壁の反射壁面の反射をもって成す間接照明とし、特定方向をもたない柔らかな均一照明として塊状青果物を照らすため、特定方向の強い反射光もなく正確な測定ができる。 Moreover, in this case the illumination means and indirect lighting forming with the reflection of the reflection wall of the enclosure walls that do not directly irradiate the bulk fruits or vegetables, for illuminating the bulk fruits or vegetables as soft uniform lighting with no specific direction, a strong reflection of a particular direction light even without it is accurate measurement. 更に照明効果が高く、従来の偏向フィルタ使用の直接照明タイプに比べて消費電力が小さくて済み、更に光源の光量が少なくて済むので消耗品である電球も小さく、且つ個数も少なくてよく電球交換の頻度が低く、ランニングコストも抑えられる。 Furthermore high lighting effect, only a small power consumption compared to direct illumination type conventional deflection filter used, further bulb is small is consumable so requires less amount of the light source, and the number is also less good bulb replacement low frequency of, running cost can be suppressed. 従って、1 Therefore, 1
台のカラーCCDカメラ使用ににあっても従来方式と比べて選別,検査の精度を著しく向上させることができる効果を有する。 Sorting as compared to a be a conventional method to a color CCD camera used in the base, has an advantage of being able to significantly improve the accuracy of the inspection.
