【０００１】
【発明の属する技術分野】
本発明は、靴選び等に際して足のサイズを計測する場合に、所定位置に載せた両足の上面と側面を撮像及び画像解析で適正に認識し、能率良く正確に足サイズ計測を行える足サイズ測定器に関する。
【０００２】
【従来の技術】
従来、正しいサイズの靴を選ぶ目安とするために、足の各部のサイズを計測する場合、スケール（定規）やメジャー（巻尺）を用いて足の長さ、最大幅、この最大幅部分の足周囲寸法（足囲）等を人手で測る方法以外に、所定の測定用機器を用いて自動的に測定する方法があった。こうした従来の足サイズ測定器としては、特開平１１−１８７９０７号公報等に示されるものがあり、これらの一例を図１３に示す。図１３は従来の足サイズ測定器の概略構成図である。
【０００３】
前記各図に示すように、従来の足サイズ測定器１００は、足底部の画像を読取るスキャナ１０１と、取込んだ画像を入力され、所定の処理を行うパーソナルコンピュータ（以下、パソコンと呼称）１０２と、パソコン１０２での画像の処理結果等を表示出力する表示器１０３と、パソコン１０２での画像の処理結果等を印刷出力するプリンタ１０４とを備える構成である。
【０００４】
前記した構成の従来の足サイズ測定器１００の動作を説明する。まず、スキャナ１０１でその上面に置かれた足の底部の画像を読取り、画像情報をパソコン１０２に取込む。パソコン１０２では、足底部の画像情報に基づいて寸法計測位置を決定し、その部分の寸法を取得する処理が行われる。得られた計測値は、パソコン１０２で他の諸データと共に表示データとして生成され、パソコン１０２から表示データが出力されて表示器１０３で画面表示が行われる。そして、必要に応じて操作者からパソコン１０２に対しプリンタ出力指示がなされると、パソコン１０２が前記表示データをプリンタ１０４に出力し、プリンタ１０４が表示データに基づいて印刷を行う。
【０００５】
一方、前記と異なる従来の他の足サイズ測定器として、特開平１１−１０１６２３号公報に記載されているものがあり、これを図１４に示す。図１４は従来の他の足サイズ測定器の構成説明図である。
前図に示すように、従来の他の足サイズ測定器２００は、足を載せる透明素材の足台２０１と、光線を足に照射する光線照射手段２０２と、光線により得られる光学像を撮像する撮像手段２０３と、撮像手段２０３から出力される画像情報を処理して足の形状情報を導く形状演算手段（図示を省略）とを備える構成である。
【０００６】
前記した構成の従来の他の足サイズ測定器２００は、足のほぼ全体の三次元形状を計測して極めて正確な形状情報を得ることができ、足全体の形状をワイヤーフレーム表示したり、任意の部分の断面形状を表示したり、また、任意の部分の寸法を算出して表示もしくは印刷出力したりすることができる。
【０００７】
【発明が解決しようとする課題】
従来の足サイズ測定器は以上のような構成を有していたことから、従来前者の場合、足底部のみの読取りとなり、足底部の画像情報からのみ各部寸法の取得処理が行われ、得られる足各部のサイズの精度が低いという課題を有していた。
また、従来後者の場合、足の正確な形状情報が得られるものの、その分精密な測定機構を備えるためにコストが高くなってしまうと共に、複数の撮像手段を有して構造が複雑で且つ形状も大きくなり、容易に持運び可能なコンパクトなものにすることが困難であるという課題を有した。
【０００８】
さらに、前記従来の足サイズ測定器のいずれも、片方の足を測定器に載せて測定した後、他方の足に載せ代え、新たに他方の足に対する測定を行う必要があるなど、片足毎に測定を行う仕組みとなっているため、測定に手間取ると共に、被測定者への負担も大きい。
本発明は前記課題を解消するためになされたもので、足の上面と側面の両方を撮像し画像解析することで足サイズ計測の精度を高められると共に、構造が簡略で取扱い性も容易となり、且つ、一度に両足について測定を行え、測定時間を短縮でき、足サイズ測定作業が効率よく行える足サイズ測定器を提供することを目的とする。
【０００９】
【課題を解決するための手段】
本発明に係る足サイズ測定器は、少なくとも両足を並列に載置可能な大きさで形成され、それぞれの足を載置される足載置部位が少なくとも略平面状である足載置台と、当該足載置台の各足載置部位に対して所定角度傾斜させて起立させ、足載置部位横に配設される複数の略平板状の鏡体と、前記足載置台から上方に離反して配設され、前記足載置台上に載置された両方の足の上面及び前記鏡体に映る足側面の鏡像を撮像し、両足の上面及び側面の鏡像の各画像情報を出力する一又は複数の撮像手段と、前記撮像手段から出力される画像情報を演算処理して両足の所定部分の寸法を導く測定処理手段とを備えるものである。
【００１０】
このように本発明においては、両足を載せる足載置台及びこの足載置台の足載置部位に沿う鏡体を配設すると共に、足の上面を直接撮像する一方、足の側面を鏡体の鏡像として撮像する撮像手段を足載置台上方に配設し、両足の上面と側面を撮像して得られた画像情報を測定処理手段で解析し、両足のサイズ情報を得ることにより、足を上方から撮像する簡略な機構となって取扱いの容易化と低コスト化が図れる上、足の上面と側面の撮像画像から靴選択に必要十分なサイズ情報を適切な精度で得られ、計測精度とコストとを高いレベルで両立させられる。また、両足を一度に撮像してサイズを測定でき、被測定者の測定時の負担を軽減できる。さらに、足を上方から撮像することで足の指形状を取得でき、足の指の特徴を判別して足に合わせた適切な靴選択のための情報を被測定者に与えられる。
【００１１】
また、本発明に係る足サイズ測定器は必要に応じて、前記撮像手段が、前記足載置台上方に一つ配設され、両足の上面及び側面鏡像を同時にまとめて撮像し、両足の上面及び側面鏡像を全て含む画像情報を出力するものである。
このように本発明においては、両足の上面及び側面鏡像をまとめて撮像する撮像手段を一つ配設し、撮像手段から両足の上面及び側面鏡像を全て含む画像情報が測定処理手段に出力され、測定処理手段による画像情報に対する処理が行われることにより、撮像手段の数を必要最小限に抑え、且つ情報伝達系統を一つに絞って測定器全体としてさらに簡略な仕組みとすることができ、より一層の低コスト化が図れる。
【００１２】
また、本発明に係る足サイズ測定器は必要に応じて、前記足載置台の二つの足載置部位を挟む外側位置に所定高さ範囲にわたって立設される略板状体の遮蔽板を備えると共に、前記鏡体が、前記足載置台の二つの足載置部位に挟まれる中間位置に配設されるものである。
このように本発明においては、足載置台の外側に遮蔽板を配設すると共に、鏡体を足載置台の中間位置に配設し、撮像画像で足の側面鏡像が足上面の中間に位置し、且つこの足側面鏡像で遮蔽板が足側面の背景として存在することにより、足の側面鏡像における足側面以外の不要な部分の画像としての取込みを遮蔽板で防ぎ、足側面のみを明確化して撮像できることとなり、足側面の認識精度を向上させてサイズ測定処理をより正確に実行できる。また、遮蔽板が鏡体を視認できる方向を制限し、被測定者の足以外の部分を他者が鏡体を介して見ることを不可能としており、被測定者のプライバシーを確実に保護できる。
【００１３】
また、本発明に係る足サイズ測定器は必要に応じて、前記足載置台の二つの足載置部位の中間位置に所定高さ範囲にわたって立設される略板状体の遮蔽板を備えると共に、前記鏡体が、前記足載置台の二つの足載置部位を挟む外側位置にそれぞれ配設されるものである。
このように本発明においては、足載置台中央に遮蔽板を配設すると共に、鏡体を足載置台の両側に配設し、撮像画像で足の側面鏡像が足上面の外側に位置し、且つこの足側面鏡像で遮蔽板が足側面の背景として存在することにより、足の側面鏡像における足側面以外の不要な部分の画像としての取込みを遮蔽板で防ぎ、足側面のみを明確化して撮像できることとなり、足側面の認識精度を向上させてサイズ測定処理をより正確に実行できる。また、遮蔽板が鏡体を視認できる方向を制限し、被測定者の足以外の部分を他者が鏡体を介して見ることを不可能としており、被測定者のプライバシーを確実に保護できる。
【００１４】
【発明の実施の形態】
（本発明の第１の実施形態）
以下、本発明の第１の実施形態に係る足サイズ測定器を図１ないし図７に基づいて説明する。図１は本実施形態に係る足サイズ測定器の概略構成図、図２は本実施形態に係る足サイズ測定器のブロック図、図３は本実施形態に係る足サイズ測定器の要部側面図、図４は本実施形態に係る足サイズ測定器の要部正面図、図５は本実施形態に係る足サイズ測定器の要部平面図、図６は本実施形態に係る足サイズ測定器における撮像イメージ説明図、図７は本実施形態に係る足サイズ測定器における足形状及び所定部位の抽出状態説明図である。
【００１５】
前記各図に示すように、本実施形態に係る足サイズ測定器１は、両足を並列に載置可能な大きさで形成される平面形状が略矩形の足載置台２と、この足載置台２の各足載置部位２ａに対して所定角度傾斜させて二つの足載置部位２ａに挟まれた中間位置にそれぞれ配設される二つの略平板状の鏡体３と、前記足載置台２の二つの足載置部位２ａを挟む外側位置に所定高さ範囲にわたって立設される略板状体の遮蔽板４と、前記足載置台２から上方に所定寸法離して配設され、足載置台２上に載置された両足の上面並びに前記鏡体３に映る足側面の鏡像をまとめて撮像し、両足の上面及び側面鏡像の両方を含む画像情報を出力する撮像手段としてのカメラ５と、このカメラ５から出力される画像情報を演算処理して両足の所定部分の寸法を導く測定処理手段としてのパーソナルコンピュータ（以下、パソコンと呼称）６とを備える構成である。
【００１６】
前記足載置台２は、それぞれの足を載置される足載置部位２ａが略水平の平面状とされ、足載置台２の中心に対して左右対称に配置される構成である。この足載置部位２ａには足を載せる際の目安として足前後方向を一致させる基準線２ｂが足前方側に向うほど基準線２ｂ同士の間隔が大きくなるようにそれぞれ配設され、足を載せた状態で両足の爪先がそれぞれ外向きになるようにする仕組みである。
【００１７】
前記鏡体３は、鏡面を有する略平板状体で形成され、前記足載置台２の各足載置部位２ａに対し所定角度傾斜させて二つの足載置部位２ａに挟まれる中間位置に左右の足それぞれに対応して二枚配設される構成である。
前記遮蔽板４は、略板状体で形成され、足載置台２の二つの足載置部位２ａを挟む外側に着脱自在に立設され、撮像される足側面の鏡像において足の背景として存在する十分な高さとされる構成である。この遮蔽板４で撮像対象の足側面より遠い部分をカメラ５に対して隠し、足側面以外の不要な部分の画像としての取込みを防ぐことで、足側面のシルエットを明確にし、足側面の画像に対する認識精度を向上させる仕組みである。
【００１８】
なお、遮蔽板４については、一面を所定の濃色に、他面を所定の淡色にそれぞれ着色し、足に面する方の色を入替え可能として、被測定者の足肌や靴下の色に応じて、これらの色と濃淡が大きく異なる方の面を足に面する側に向けて足側面の背景とする構成とすることもでき、足側面のシルエットを際立たせて測定精度の向上が図れる。
【００１９】
前記カメラ５は、ＣＣＤ等を用いた公知のものであり、支持部５ａに取付けられて足載置台２上方の所定高さ位置に配設され、足上面及び鏡体３に映る足側面の鏡像を同時にまとめて撮像可能に所定角度下側に傾けた状態に支持され、前記パソコン６と所定のケーブルを介して接続され、パソコン６により動作制御されて撮像した画像情報をパソコン６に送信する仕組みである。
【００２０】
前記パソコン６は、操作者の入力動作を受けて動作指示を発信する入力手段６１と、カメラ５と接続されて画像情報を受信するインターフェース６２と、画像情報や所定の処理用プログラムを格納する記憶手段６３と、足画像及び処理結果としての足サイズ情報を画面に表示出力する表示手段としてのディスプレイ６４と、前記足画像及び足サイズ情報を紙に印刷出力する別の表示手段としてのプリンタ６５と、前記各部に対する制御を行うと共に、画像情報に対し前記処理用プログラムに基づいて所定の演算処理を行う演算制御部としてのＣＰＵ６６とを備える構成である。記憶手段６３には、規格に基づいた所定サイズごとの靴の足長、足幅、及び足囲といった各部寸法情報があらかじめデータベースとして格納されており、このデータベースを参照しつつ、ＣＰＵ６６で足各部寸法に適合する靴サイズを導き、この靴サイズをディスプレイ６４やプリンタ６５で出力できる仕組みである。
【００２１】
次に、前記構成に基づく足サイズ測定器の測定動作について説明する。あらかじめ、パソコン６では処理用プログラムを起動させ、カメラ５からの画像情報の入力待機状態としておく。まず、被測定者が足載置台２上に両方の足を爪先側がカメラ５寄りに位置するようにして載せ、さらに足載置台２上の基準線２ｂに足の左右方向の中心を合わせて、足を静止させる。ここで被測定者が基準線２ｂを目安にして足の位置を合わせることから、被測定者が容易に撮像を正しく行える箇所に足を位置させられ、位置合せに係る測定者と被測定者双方の負担を軽減できる。
【００２２】
この状態で、足上面と鏡体３に映る足側面の鏡像がカメラ５の撮像範囲にあり、測定者はパソコン６の入力手段６１を操作し、パソコン６を通じてカメラ５に対する撮像指示を行う。カメラ５は両足の足上面と足側面鏡像をまとめて撮像し、左右の足上面の間に足側面の鏡像が位置する撮像画像（図６参照）を取得して、画像情報をパソコン６側へ出力する。
【００２３】
パソコン６では、インターフェース６２が画像情報を受取り、ＣＰＵ６６がこの画像情報を一旦記憶手段６３に格納する。画像情報がパソコン６に取込まれた後、測定者は測定結果の識別のために被測定者の氏名等の情報を入力手段６１の操作により入力する。入力された情報は画像情報と共に記憶手段６３に格納される他、必要に応じてディスプレイ６４に表示される。
【００２４】
ここで、測定者が入力手段６１を操作してパソコン６に測定処理開始を指示すると、ＣＰＵ６６が処理用プログラムに基づいて、記憶手段６３に格納した画像情報に対する処理を行い、両足それぞれについて足上面の画像及び足側面鏡像の画像から足形状を特定し、足の最前部点と最後部点、足の親指側最突出点と小指側最突出点、足の最大幅部位での最大高さ点をそれぞれ抽出する（図７参照）。そして、最前部点から最後部点までの距離（足長）、親指側最突出点から小指側最突出点までの距離（足幅）、足底から前記最大高さ点までの高さ（足高）をそれぞれ算出し、さらに、足幅と足高から所定の計算式に基づいて足の親指側最突出点、最大高さ点、及び小指側最突出点を通る周囲長さ（足囲）を算出する。
【００２５】
続いて、得られた足長、足幅、及び足囲の各測定値のうち、両方の足でより大きな方の値について、ＣＰＵ６６が記憶手段６３にデータベースとして格納していた靴の各サイズ毎の足長、足幅、及び足囲の各寸法値と参照比較し、足の各測定値より大きく且つ最も近い寸法値を有する靴のサイズを導く。導かれた靴のサイズは、被測定者の選択の目安とすべき靴サイズとして各測定値と合わせてディスプレイ６４に画面表示として出力される。被測定者の足に最適となる靴サイズをすぐ確認できることから、得られた足サイズ情報を基に被測定者もしくは測定者が規格表等から適合する靴サイズを探し出す手間が省け、適切な靴選択が容易に行える。
【００２６】
ディスプレイ６４による表示が行われた後、必要に応じて、測定者による入力手段６１の操作により、パソコン６に対し印刷出力指示が行われると、ＣＰＵ６６は印刷処理として、ディスプレイ６４に表示された画面と同じイメージ画像をプリンタ６５に出力させる。
このように、本実施形態に係る足サイズ測定器は、足載置台２上の平らな足載置部位２ａに載せた足の側面を映す鏡体３を配設すると共に、足の上面を直接撮像し、且つ足の側面を鏡像として撮像するカメラ５を一つ配設し、両足の上面と側面鏡像を一度に撮像して得られた画像情報をパソコン６で解析して足のサイズ情報を得ることから、足の撮像が簡略なシステムで行え、取扱いの容易化と低コスト化が図れる上、両足の上面と側面の撮像画像から靴選択に必要十分なサイズ情報を適切な精度で得られ、靴を選ぼうとする人に対し負担をかけずに短時間で足寸法を測定して正しい靴選びを適切に支援できる。また、足を上方から撮像することで足の指形状を取得でき、足の指の特徴を判別して足に合わせた適切な靴選択のための情報を被測定者に与えられる。さらに、遮蔽板４が鏡体３を視認できる方向を制限し、被測定者の足以外の部分を他者が鏡体３を介して見ることを不可能とすることから、被測定者のプライバシー保護も確実に行える。
【００２７】
（本発明の第２の実施形態）
本発明の第２の実施形態に係る足サイズ測定器を図８ないし図１１に基づいて説明する。図８は本実施形態に係る足サイズ測定器の要部側面図、図９は本実施形態に係る足サイズ測定器の要部正面図、図１０は本実施形態に係る足サイズ測定器の要部平面図、図１１は本実施形態に係る足サイズ測定器における撮像イメージ説明図である。
【００２８】
前記各図に示すように、本実施形態に係る足サイズ測定器１は、前記第１の実施形態と同様、足載置台２と、鏡体３と、遮蔽板４と、カメラ５と、パソコン６とを備える一方、異なる構成として、鏡体３が足載置台２の二つの足載置部位を挟む外側位置に配設されると共に、遮蔽板４が足載置台２の二つの足載置部位に挟まれる中間位置に立設される構成を有するものである。
【００２９】
前記足載置台２は、前記第１の実施形態同様、足載置部位２ａが略水平の平面状とされて足載置台２の中心に対して左右対称に配置される一方、足載置部位２ａで足を載せる際の目安となる基準線２ｂは基準線２ｂ同士平行として足載置台２の前後方向と一致させてそれぞれ配設され、足を載せた状態で両足の爪先がそれぞれ真っ直ぐ前方に向くようにする仕組みである。
【００３０】
前記鏡体３は、足載置台２の各足載置部位２ａに対し所定角度傾斜させて二つの足載置部位２ａを挟む外側位置で且つ足載置台２中心に対し左右対称となる位置に左右の足それぞれに対応して二枚配設される構成である。この鏡体３は、足の前方側で鏡体３同士の間隔がより大きくなるよう足載置台２の前後方向に対しそれぞれ所定角度ずらして配設されており、鏡体３に映る足側面がカメラ５で撮像される際の鏡体３と足、及び鏡体３とカメラ５との距離の違いに伴って生じる撮像画像中の足形状誤差を小さくし、測定精度を確保できる仕組みである。
【００３１】
前記遮蔽板４は、足載置台２の二つの足載置部位２ａに挟まれた足載置台２の中央に着脱自在に立設される構成である。前記第１の実施形態同様、遮蔽板４で撮像対象の足側面以外の不要な部分の画像としての取込みを防いで、足側面の画像に対する認識精度を向上させられる仕組みである。
次に、前記構成に基づく足サイズ測定器の測定動作について説明する。前記第１の実施形態同様、まず被測定者が足載置台２上に両方の足を爪先側がカメラ５寄りに位置するようにして載せ、さらに足載置台２上の基準線２ｂに足の左右方向の中心を合わせて、足を静止させる。この状態で、足上面と鏡体３に映る足側面の鏡像がカメラ５の撮像範囲にあり、測定者はパソコン６の入力手段６１を操作し、パソコン６を通じてカメラ５に対する撮像指示を行う。カメラ５は両足の足上面と足側面鏡像をまとめて撮像し、両足上面の外側に左右の足側面の鏡像がそれぞれ位置する撮像画像（図１１参照）を取得して、画像情報をパソコン６側へ出力する。
【００３２】
これ以降の、パソコン６による画像情報に基づく測定処理と結果の出力については、前記第１の実施形態と同じであり、説明を省略する。
このように、本実施形態に係る足サイズ測定器は、足載置台２上の平らな足載置部位２ａの外側に足の側面を映す鏡体３を配設し、足載置台２上方のカメラ５で両足の上面と側面鏡像を一度に撮像して得られた画像情報をパソコン６で解析して足のサイズ情報を得ることから、前記第１の実施形態同様、足の撮像が簡略なシステムで行え、取扱いの容易化と低コスト化が図れる上、両足の上面と側面の撮像画像から靴選択に必要十分なサイズ情報を適切な精度で得られ、被測定者にかかる負担も必要最小限にできる。また、足を上方から撮像することで足の指形状を取得でき、足の指の特徴を判別して足に関する正確な情報を提供できる。さらに、足載置台２中央の遮蔽板４が鏡体３を視認できる方向を制限し、被測定者の足以外の部分を鏡体３を介しても見えなくして被測定者のプライバシーを確実に保護できる。
【００３３】
なお、前記第１及び第２の各実施形態に係る足サイズ測定器においては、一つのカメラ５で両足の上面及び側面の鏡像を全て撮像する構成としているが、これに限らず、図１２に示すように、二つ以上のカメラ５を用いて左右の足毎に上面及び側面の鏡像を撮像する構成とすることもでき、それぞれの足をより正面に近い位置で捉えて撮像画像を取得することで、足各位置とカメラ５、及び鏡体３各位置とカメラ５との距離の違いに伴う撮像画像中の足形状誤差を小さくし、より正確な寸法測定結果を取得できる。
【００３４】
また、前記第１及び第２の各実施形態に係る足サイズ測定器において、足載置台２の足載置部位２ａは略水平とされる構成としているが、これに限らず、足載置部位２ａを足載置台２の前後方向及び左右方向にカメラ５の撮像方向に対応させて所定角度傾斜させる構成とすることもでき、足各位置とカメラ５との距離の違いに伴う撮像画像中の足形状誤差を小さくし、より高精度な測定を行える。
【００３５】
【発明の効果】
以上のように本発明によれば、両足を載せる足載置台及びこの足載置台の足載置部位に沿う鏡体を配設すると共に、足の上面を直接撮像する一方、足の側面を鏡体の鏡像として撮像する撮像手段を足載置台上方に配設し、両足の上面と側面を撮像して得られた画像情報を測定処理手段で解析し、両足のサイズ情報を得ることにより、足を上方から撮像する簡略な機構となって取扱いの容易化と低コスト化が図れる上、足の上面と側面の撮像画像から靴選択に必要十分なサイズ情報を適切な精度で得られ、計測精度とコストとを高いレベルで両立させられるという効果を奏する。また、両足を一度に撮像してサイズを測定でき、被測定者の測定時の負担を軽減できるという効果を有する。さらに、足を上方から撮像することで足の指形状を取得でき、足の指の特徴を判別して足に合わせた適切な靴選択のための情報を被測定者に与えられるという効果を有する。

【００３７】
また、本発明によれば、足載置台の外側に遮蔽板を配設すると共に、鏡体を足載置台の中間位置に配設し、撮像画像で足の側面鏡像が足上面の中間に位置し、且つこの足側面鏡像で遮蔽板が足側面の背景として存在することにより、足の側面鏡像における足側面以外の不要な部分の画像としての取込みを遮蔽板で防ぎ、足側面のみを明確化して撮像できることとなり、足側面の認識精度を向上させてサイズ測定処理をより正確に実行できるという効果を有する。さらに、遮蔽板が鏡体を視認できる方向を制限し、被測定者の足以外の部分を他者が鏡体を介して見ることを不可能としており、被測定者のプライバシーを確実に保護できるという効果を有する。
