　次に、処理装置の機能構成を説明する。図３に、処理装置１０の機能ブロック図の一例を示す。図示するように、処理装置１０は、選択部１１と、算出部１２とを有する。 Next, the functional configuration of the processing device will be described. FIG. 3 shows an example of a functional block diagram of the processing device 10. As illustrated, the processing device 10 includes a selection unit 11 and a calculation unit 12.
　選択部１１は、ユーザ入力に基づき、可動域の測定対象を選択する。例えば、選択部１１は、測定対象を選択するＵＩ（user interface）画面をディスプレイに出力し、当該ＵＩ画面からユーザ入力を受付ける。 The selection unit 11 selects a measurement object of the movable range based on a user input. For example, the selection unit 11 outputs a UI (user @ interface) screen for selecting a measurement target to a display, and receives a user input from the UI screen.
　一例として、選択部１１は、図４に示すように、「全項目測定」と「個別測定」とが選択可能なＵＩ画面を出力してもよい。 As an example, as shown in FIG. 4, the selection unit 11 may output a UI screen from which “all item measurement” and “individual measurement” can be selected.
　ユーザ入力で「全項目測定」が指定された場合、選択部１１は、全ての測定対象を所定順に１つずつ選択する。 (4) When “all item measurement” is specified by the user input, the selection unit 11 selects all the measurement targets one by one in a predetermined order.
　一方、ユーザ入力で「個別測定」が指定された場合、選択部１１は、図５に示すように複数の測定対象を選択可能に一覧表示したＵＩ画面をディスプレイに出力する。そして、選択部１１は、当該ＵＩ画面においてユーザ入力で指定された測定対象を選択する。図５に示す複数の測定対象各々の詳細は以下の実施形態で説明する。 On the other hand, when “individual measurement” is designated by a user input, the selection unit 11 outputs a UI screen that lists a plurality of measurement targets in a selectable manner as shown in FIG. 5 on a display. Then, the selection unit 11 selects the measurement target specified by the user input on the UI screen. Details of each of the plurality of measurement objects shown in FIG. 5 will be described in the following embodiments.
　その他、選択部１１は、動作を指定するＵＩ画面をディスプレイに出力し、当該ＵＩ画面からユーザ入力を受付けてもよい。ＵＩ画面で指定可能な動作は、所定のスポーツ時に行う動作であってもよい。例えば、野球の投げる動作、野球の打つ動作、テニスのサーブの動作、テニスのフォアハンドの動作、テニスのボレーの動作等が例示されるが、これらに限定されない。その他、ＵＩ画面で指定可能な動作は、日常生活で行う動作であってもよい。例えば、階段を上がる動作、物を持ち上げる動作等が例示されるが、これらに限定されない。この場合、選択部１１は、予め、各動作に、各動作に関連する測定対象を対応付けた情報を記憶しておく。そして、選択部１１は、ユーザ入力で指定された動作に対応する測定対象を、所定順に１つずつ選択する。 In addition, the selection unit 11 may output a UI screen designating an operation to a display, and accept a user input from the UI screen. The operation that can be specified on the UI screen may be an operation performed during a predetermined sport. Examples include, but are not limited to, a baseball throwing action, a baseball hitting action, a tennis serve action, a tennis forehand action, a tennis volley action, and the like. In addition, the operation that can be specified on the UI screen may be an operation performed in daily life.

In this case, the selection unit 11 previously stores information in which each operation is associated with a measurement target associated with each operation. Then, the selection unit 11 selects measurement targets corresponding to the operation specified by the user input one by one in a predetermined order.
　算出部１２は、被験者を撮影した画像を、選択された測定対象に対応した解析方法で解析することで、選択された測定対象の可動域を示す測定値を算出する。「画像」は、被験者１００が所定の動きを行う様子を３次元カメラ２００で撮影した画像である。 The calculation unit 12 calculates a measurement value indicating the movable range of the selected measurement target by analyzing the image of the subject by an analysis method corresponding to the selected measurement target. The “image” is an image of the subject 100 performing a predetermined movement with the three-dimensional camera 200.
　処理装置１０には、予め、複数の測定対象各々に対応した画像データの解析方法を示すアルゴリズムが記憶されている。上述の通り、複数の測定対象各々に対応したアルゴリズムは、身体の所定の部位（例：肘、肩）を特定し、特定した部位に基づき可動域を示す値を算出する点で共通するが、特定する部位や特定した部位に基づき算出する値（例：角度、距離等）等が互いに異なる。算出部１２は、選択部１１が選択した測定対象に対応したアルゴリズムで画像を解析することで、選択された測定対象の可動域を示す測定値を算出する。アルゴリズムの詳細は、以下の実施形態で説明する。 The processing apparatus 10 stores in advance an algorithm indicating a method of analyzing image data corresponding to each of a plurality of measurement targets. As described above, the algorithm corresponding to each of the plurality of measurement targets specifies a predetermined part of the body (eg, elbow, shoulder), and is common in that a value indicating the range of motion is calculated based on the specified part. The part to be specified and the value (eg, angle, distance, etc.) calculated based on the specified part are different from each other. The calculation unit 12 analyzes the image using an algorithm corresponding to the measurement target selected by the selection unit 11 to calculate a measurement value indicating the movable range of the selected measurement target. Details of the algorithm will be described in the following embodiments.
　次に、図６のフローチャートを用いて、本実施形態の処理装置１０の処理の流れの一例を説明する。 Next, an example of the processing flow of the processing device 10 of the present embodiment will be described with reference to the flowchart of FIG.
　まず、選択部１１が、ユーザ入力に基づき、可動域の測定対象を選択する（Ｓ１０）。次いで、算出部１２が、被験者を撮影した画像を、Ｓ１０で選択された測定対象に対応した解析方法で解析することで、選択された測定対象の可動域を示す測定値を算出する（Ｓ２０）。 First, the selection unit 11 selects a measurement object of the movable range based on a user input (S10). Next, the calculation unit 12 calculates the measurement value indicating the movable range of the selected measurement target by analyzing the image obtained by photographing the subject using an analysis method corresponding to the measurement target selected in S10 (S20). .
　以上説明したように、本実施形態の処理装置１０は、評価部位及びその部位の動作方向の少なくとも一方が互いに異なる複数の測定対象毎に画像データの解析方法（アルゴリズム）を用意しておき、選択された測定対象に対応する解析方法で被験者を撮影した画像を解析し、測定対象の可動域を示す測定値を算出する。このような処理装置１０によれば、身体の複数の部位や複数の動作方向の可動域を、専門的な知識なしで評価できる。 As described above, the processing device 10 of the present embodiment prepares an image data analysis method (algorithm) for each of a plurality of measurement targets having at least one of the evaluation site and the operation direction of the site different from each other, An image obtained by photographing the subject is analyzed by an analysis method corresponding to the measured object, and a measurement value indicating a movable range of the object is calculated. According to such a processing device 10, it is possible to evaluate the movable range of a plurality of parts of the body and the plurality of movement directions without special knowledge.
　また、本実施形態の処理装置１０によれば、コンピュータが予め定められたアルゴリズムに基づき画像を解析することで可動域が算出されるので、「人が可動域を評価する場合に比べて短時間で可動域が算出される」、「高い再現性が得られる」等の優れた効果が得られる。 In addition, according to the processing device 10 of the present embodiment, the range of motion is calculated by the computer analyzing the image based on the predetermined algorithm. , The movable range is calculated, and high reproducibility is obtained.
　また、本実施形態の処理装置１０の一例によれば、ユーザ入力で動作（例：野球の投げる動作、野球の打つ動作、テニスのサーブの動作、テニスのフォアハンドの動作、テニスのボレーの動作等）が指定されると、指定された動作に関連する測定対象が選択される。この場合、ユーザが測定対象に関する専門的な知識を有さない場合であっても、自身に関連する動作を指定するという単純な作業を行うだけで、評価すべき測定対象の選択が実現される。すなわち、非専門性がより高くなる。 In addition, according to an example of the processing device 10 of the present embodiment, an operation by a user input (eg, a baseball throwing operation, a baseball hitting operation, a tennis serve operation, a tennis forehand operation, a tennis volley operation, and the like) When () is specified, a measurement object related to the specified operation is selected. In this case, even if the user does not have specialized knowledge about the measurement target, the selection of the measurement target to be evaluated is realized by simply performing the simple operation of designating the operation related to the user. . That is, the non-specialty becomes higher.
＜第２の実施形態＞
　本実施形態の処理装置１０は、可動域を示す測定値の算出方法がより具体化される点で、第１の実施形態と異なる。以下、詳細に説明する。 <Second embodiment>
The processing apparatus 10 of the present embodiment is different from the first embodiment in that the method of calculating the measurement value indicating the movable range is more concretely performed. The details will be described below.
　処理装置１０のハードウエア構成の一例は、第１の実施形態と同様である。 の 一 An example of the hardware configuration of the processing device 10 is the same as that of the first embodiment.
　処理装置１０の機能ブロック図の一例は、第１の実施形態同様、図３で示される。図示するように、処理装置１０は、選択部１１と、算出部１２とを有する。選択部１１の構成は、第１の実施形態と同様である。 An example of a functional block diagram of the processing device 10 is shown in FIG. 3 as in the first embodiment. As illustrated, the processing device 10 includes a selection unit 11 and a calculation unit 12. The configuration of the selection unit 11 is the same as in the first embodiment.
　算出部１２は、第１の実施形態同様、被験者を撮影した画像を、選択部１１により選択された測定対象に対応した解析方法で解析することで、選択された測定対象の可動域を示す測定値を算出する。 As in the first embodiment, the calculation unit 12 analyzes the image of the subject by using an analysis method corresponding to the measurement target selected by the selection unit 11 to measure the range of motion of the selected measurement target. Calculate the value.
　具体的には、まず、算出部１２は、被験者を画像上で特定する。画像内に存在する人を特定する手段は特段制限されず、あらゆる技術を利用して実現できる。 Specifically, first, the calculation unit 12 specifies the subject on the image. Means for identifying a person present in the image is not particularly limited, and can be realized using any technique.
　次いで、算出部１２は、選択された測定対象に関連した身体の箇所を画像上で特定する。特定する箇所は、頭、首、左右の手先、左右の手の親指、左右の手首、左右の肘、左右の肩、左右の肩の真ん中、左右の股関節、左右の股関節の真ん中、骨盤の真ん中、脊柱の真ん中、左右の膝、左右の足首、左右の足先等が挙げられるが、これらに限定されない。これらの箇所は、身体全体の外観の特徴や、各箇所の外観の特徴等に基づき、画像解析で特定することができる。 Next, the calculation unit 12 specifies the location of the body related to the selected measurement target on the image. The location to specify is the head, neck, left and right hands, left and right thumbs, left and right wrists, left and right elbows, left and right shoulders, left and right shoulder middle, left and right hip joints, left and right hip joint middle, pelvic middle , The center of the spine, left and right knees, left and right ankles, left and right toes, etc., but are not limited thereto. These locations can be identified by image analysis based on the appearance characteristics of the entire body, the appearance characteristics of each location, and the like.
　次いで、算出部１２は、特定した身体の箇所に基づき測定値を算出する。 Next, the calculation unit 12 calculates a measurement value based on the specified body part.
　例えば、算出部１２は、身体の第１の箇所と第２の箇所とを結ぶ線と、基準線とのなす角を、可動域を示す測定値として算出してもよい。 For example, the calculation unit 12 may calculate an angle between a line connecting the first point and the second point of the body and a reference line as a measurement value indicating a movable range.
　その他、算出部１２は、身体の第３の箇所と第４の箇所との距離を、可動域を示す測定値として算出してもよい。 In addition, the calculation unit 12 may calculate the distance between the third location and the fourth location of the body as a measurement value indicating the range of motion.
　その他、算出部１２は、被験者が第１の姿勢をとっている時の身体の第５の箇所と、被験者が同位置で第１の姿勢と異なる第２の姿勢をとっている時の身体の第５の箇所との距離を、可動域を示す測定値として算出してもよい。 In addition, the calculation unit 12 calculates the fifth position of the body when the subject is in the first posture and the body of the body when the subject is in the second position different from the first posture at the same position. The distance to the fifth point may be calculated as a measured value indicating the movable range.
　なお、図７に示すように、予め、測定対象毎に特定する身体の箇所を示した情報が処理装置１０に登録されていてもよい。そして、算出部１２は、当該情報と、選択部１１により選択された測定対象とに基づき、特定する身体の箇所を把握してもよい。また、算出部１２は、図７に示す情報に基づき、算出する値を把握してもよい。 As shown in FIG. 7, information indicating the location of the body specified for each measurement target may be registered in the processing device 10 in advance. Then, the calculation unit 12 may grasp the location of the body to be specified based on the information and the measurement target selected by the selection unit 11. Further, the calculation unit 12 may grasp the value to be calculated based on the information shown in FIG.
　ここで、各測定対象を詳細に説明するとともに、各測定対象で特定される身体の箇所の一例と、画像解析方法の一例とを説明する。 Here, each measurement target will be described in detail, and an example of a body part specified by each measurement target and an example of an image analysis method will be described.
「肩関節屈曲（図５の「肩屈曲右」、「肩屈曲左」）」
　肩関節屈曲では、図８及び図９に示すように、被験者１００は、３次元カメラ２００（不図示）に正対し、気を付けの姿勢から手のひらを内側（身体側）に向けた状態で身体の前方を経由して腕を上方に上げていく。肩屈曲右では被験者１００は右腕を動作させ、肩屈曲左では被験者１００は左腕を動作させる。 "Shoulder flexion (" shoulder flexion right "," shoulder flexion left "in Fig. 5)"
In the shoulder joint flexion, as shown in FIG. 8 and FIG. 9, the subject 100 faces the three-dimensional camera 200 (not shown), and turns his / her body in a state in which the palm is turned to the inside (body side) from a careful posture. Raise your arm upwards through the front of the. The subject 100 operates the right arm with the shoulder flexion right, and operates the left arm with the shoulder flexion left.
　画像解析方法は、例えば次のようなもの考えられる。まず、算出部１２は、画像解析で、動作させる側の肩と肘とを特定する（図８及び図９中、点で示す位置）。次いで、算出部１２は、肩からＹ軸方向に下ろした線を基準線（図８中、Ｓで示す線）として定めるとともに、肩と肘とを結ぶ線を移動線として定める。なお、ＸＹＺ軸方向は図１及び図８に示す通りであるが、３次元カメラ２００と被験者１００とを結ぶ方向がｚ軸方向、垂直方向がＹ軸方向、水平方向であって３次元カメラ２００の左右方向がＸ軸方向である。 The image analysis method is, for example, as follows. First, the calculation unit 12 specifies the shoulder and elbow on the side to be operated by image analysis (the positions indicated by the dots in FIGS. 8 and 9). Next, the calculation unit 12 determines a line lowered from the shoulder in the Y-axis direction as a reference line (a line indicated by S in FIG. 8), and determines a line connecting the shoulder and the elbow as a movement line. Note that the XYZ axis directions are as shown in FIGS. 1 and 8, but the direction connecting the three-dimensional camera 200 and the subject 100 is the z-axis direction, the vertical direction is the Y-axis direction, and the horizontal direction. Is the X-axis direction.
　そして、算出部１２は、基準線をＹＺ平面に投影した線と、移動線をＹＺ平面に投影した線とのなす角を、肩関節屈曲の可動域を示す測定値として算出する。 算出 Then, the calculation unit 12 calculates an angle formed between a line obtained by projecting the reference line on the YZ plane and a line obtained by projecting the movement line on the YZ plane as a measured value indicating the movable range of the flexion of the shoulder joint.
　算出部１２は、例えば、被験者１００が上記一連の動作を行う様子を示す動画像を解析することができる。この場合、算出部１２は、フレーム毎に画像を解析し、フレーム毎に上記なす角を算出することができる。そして、算出部１２は、フレーム毎に算出した複数のなす角の中の最大値を、肩関節屈曲の可動域を示す測定値として算出することができる。 The calculation unit 12 can analyze, for example, a moving image showing a state in which the subject 100 performs the above-described series of operations. In this case, the calculation unit 12 can analyze the image for each frame and calculate the angle formed for each frame. Then, the calculation unit 12 can calculate the maximum value among the plurality of angles calculated for each frame as a measurement value indicating the movable range of the flexion of the shoulder joint.
　なお、ここで説明した画像解析方法は一例であり、これに準じた他の方法を採用することもできる。 The image analysis method described here is an example, and another method according to the image analysis method can be adopted.
「肩関節外旋（図５の「肩外旋右」、「肩外旋左」）」
　肩関節外旋では、図１０及び図１１に示すように、被験者１００は、３次元カメラ２００（不図示）に正対し、外転９０°の姿勢から手先が上を向くように肘を９０°曲げ、手のひらが内側を向いた状態（手の親指が体の後方を向く状態）で肘から先を体の後方側に倒していく。肩外旋右では被験者１００は右腕を動作させ、肩外旋左では被験者１００は左腕を動作させる。 "Shoulder external rotation (Fig. 5" Shoulder external rotation right "," Shoulder external rotation left ")"
In the shoulder external rotation, as shown in FIGS. 10 and 11, the subject 100 faces the three-dimensional camera 200 (not shown), and turns the elbow 90 ° so that the hand faces upward from the posture of the abduction 90 °. Bend, with the palm facing inward (the thumb of the hand is facing the back of the body), tip from the elbow to the back of the body. The subject 100 operates the right arm when the shoulder external rotation is right, and the subject 100 operates the left arm when the shoulder external rotation is left.
　画像解析方法は、例えば次のようなもの考えられる。まず、算出部１２は、画像解析で、動作させる側の肘と手首とを特定する（図１０及び図１１中、点で示す位置）。次いで、算出部１２は、肘からＺ軸方向（身体の前方側）に伸ばした線を基準線（図１０中、Ｓで示す線）として定めるとともに、肘と手首とを結ぶ線を移動線として定める。 The image analysis method is, for example, as follows. First, the calculation unit 12 specifies an elbow and a wrist on the side to be operated by image analysis (positions indicated by dots in FIGS. 10 and 11). Next, the calculation unit 12 determines a line extending from the elbow in the Z-axis direction (the front side of the body) as a reference line (a line indicated by S in FIG. 10), and a line connecting the elbow and the wrist as a movement line.

　例えば、評価部１３は、２パターンの測定値の差を複数レベルに分類し、レベル毎に測定対象の状態を定義した第１の状態定義情報を保持しておいてもよい。第１の状態定義情報は、例えば、差がＤ０～Ｄ１は「良好」、差がＤ１～Ｄ２は「やや危険」、差がＤ２～Ｄ３は「危険」等である。そして、評価部１３は、第１の状態定義情報と、２パターンの測定値の差に基づき、各測定対象の状態を評価してもよい。 For example, the evaluation unit 13 may classify the difference between the measured values of the two patterns into a plurality of levels, and hold first state definition information defining the state of the measurement target for each level. The first state definition information includes, for example, “good” for the difference D0 to D1, “slightly dangerous” for the difference D1 to D2, and “dangerous” for the difference D2 to D3. Then, the evaluation unit 13 may evaluate the state of each measurement target based on the first state definition information and the difference between the measured values of the two patterns.
　なお、第１の状態定義情報は、測定対象毎に定義されてもよい。すなわち、「良好」、「やや危険」、「危険」等の各状態となる差の数値範囲は、測定対象毎に異なってもよい。 Note that the first state definition information may be defined for each measurement target. In other words, the numerical range of the difference in each state such as “good”, “slightly dangerous”, and “dangerous” may be different for each measurement target.
「第２の評価方法」
　評価部１３は、測定値と参照値との比較結果に基づき、測定対象の状態を評価することができる。 "Second evaluation method"
The evaluation unit 13 can evaluate the state of the measurement target based on the comparison result between the measured value and the reference value.
　例えば、評価部１３は、測定値を複数レベルに分類し、レベル毎に測定対象の状態を定義した第２の状態定義情報を保持しておいてもよい。第２の状態定義情報は、例えば、測定値がＣ０～Ｃ１は「良好」、測定値がＣ１～Ｃ２は「やや危険」、測定値がＣ２～Ｃ３は「危険」等である。そして、評価部１３は、第２の状態定義情報と、測定値とに基づき、各測定対象の状態を評価してもよい。 For example, the evaluation unit 13 may classify the measured values into a plurality of levels, and hold second state definition information that defines the state of the measurement target for each level. The second state definition information includes, for example, “good” for measured values C0 to C1, “slightly dangerous” for measured values C1 to C2, and “dangerous” for measured values C2 to C3. Then, the evaluation unit 13 may evaluate the state of each measurement target based on the second state definition information and the measurement value.
　なお、第２の状態定義情報は、測定対象毎に定義されてもよい。すなわち、「良好」、「やや危険」、「危険」等の各状態となる測定値の数値範囲は、測定対象毎に異なってもよい。また、第２の状態定義情報は、被験者の属性毎（例：年齢ごと、性別ごと）に定義されてもよい。すなわち、「良好」、「やや危険」、「危険」等の各状態となる測定値の数値範囲は、被験者の属性毎（例：年齢ごと、性別ごと）に異なってもよい。この場合、処理装置１０は任意の手段で被験者の属性を指定する値の入力を受付け、評価部１３は入力された値に基づき被験者の属性を特定し、特定した属性に対応した第２の状態定義情報を用いて測定対象の状態を評価する。 The second state definition information may be defined for each measurement target. That is, the numerical value ranges of the measured values in each state such as “good”, “slightly dangerous”, and “dangerous” may be different for each measurement target. In addition, the second state definition information may be defined for each attribute of the subject (for example, for each age and each sex). That is, the numerical value ranges of the measured values in each of the states such as “good”, “slightly dangerous”, and “dangerous” may be different for each attribute of the subject (eg, for each age, each gender). In this case, the processing device 10 receives an input of a value specifying the attribute of the subject by any means, the evaluation unit 13 specifies the attribute of the subject based on the input value, and the second state corresponding to the specified attribute. The state of the measurement target is evaluated using the definition information.
「第３の評価方法」
　評価部１３は、同被験者の測定値（例：最新の測定値）と過去の測定値に基づき、測定対象の状態を評価する。第３の評価方法によれば、被験者の測定対象の状態の変化（悪化、現状維持、良化等）を評価することができる。 "Third evaluation method"
The evaluation unit 13 evaluates the state of the measurement target based on the measurement value (eg, the latest measurement value) of the subject and the past measurement value. According to the third evaluation method, it is possible to evaluate a change (deterioration, maintenance of the current state, improvement, etc.) of the state of the measurement target of the subject.
　例えば、評価部１３は、過去の測定値に基づき測定対象の状態を定義した第３の状態定義情報を保持しておいてもよい。第３の状態定義情報は、例えば、測定値が「過去の測定値マイナスα以上過去の測定値プラスα以下」の場合は「現状維持」、測定値が「過去の測定値マイナスα未満」の場合は「悪化」、測定値が「過去の測定値プラスαより大」の場合は「良化」等である。そして、評価部１３は、第３の状態定義情報と、過去の測定値と、例えば最新の測定値とに基づき、各測定対象の状態を評価してもよい。 For example, the evaluation unit 13 may hold third state definition information that defines the state of the measurement target based on past measurement values. The third state definition information includes, for example, when the measured value is “past measured value minus α or more and past measured value plus α or less”, the current state is “maintained”, and the measured value is “past measured value minus less than α”. In this case, the result is “deteriorated”, and when the measured value is “greater than the past measured value plus α”, it is “improved”. Then, the evaluation unit 13 may evaluate the state of each measurement target based on the third state definition information, the past measurement value, and, for example, the latest measurement value.
　なお、第３の状態定義情報は、測定対象毎に定義されてもよい。すなわち、上記αの値は、測定対象毎に異なってもよい。また、第３の状態定義情報は、被験者の属性毎（例：年齢ごと、性別ごと）に定義されてもよい。すなわち、上記αの値は、被験者の属性毎（例：年齢ごと、性別ごと）に異なってもよい。この場合、処理装置１０は任意の手段で被験者の属性を指定する値の入力を受付け、評価部１３は入力された値に基づき被験者の属性を特定し、特定した属性に対応した第３の状態定義情報を用いて測定対象の状態を評価する。 The third state definition information may be defined for each measurement target. That is, the value of α may be different for each measurement target. Further, the third state definition information may be defined for each attribute of the subject (for example, for each age and each gender). That is, the value of α may be different for each attribute of the subject (eg, for each age, each gender). In this case, the processing device 10 receives an input of a value specifying the attribute of the subject by any means, the evaluation unit 13 specifies the attribute of the subject based on the input value, and the third state corresponding to the specified attribute. The state of the measurement target is evaluated using the definition information.
　次に、図２８のフローチャートを用いて、本実施形態の処理装置１０の処理の流れの一例を説明する。 Next, an example of a processing flow of the processing device 10 of the present embodiment will be described with reference to the flowchart in FIG.
　まず、選択部１１が、ユーザ入力に基づき、可動域の測定対象を選択する（Ｓ１０）。次いで、算出部１２が、被験者を撮影した画像を、Ｓ１０で選択された測定対象に対応した解析方法で解析することで、選択された測定対象の可動域を示す測定値を算出する（Ｓ２０）。次いで、評価部１３が、Ｓ２０で算出された測定値に基づき、測定対象の状態を評価する（Ｓ３０）。 First, the selection unit 11 selects a measurement object of the movable range based on a user input (S10). Next, the calculation unit 12 calculates the measurement value indicating the movable range of the selected measurement target by analyzing the image obtained by photographing the subject using an analysis method corresponding to the measurement target selected in S10 (S20). . Next, the evaluation unit 13 evaluates the state of the measurement target based on the measurement value calculated in S20 (S30).

　また、本実施形態の処理装置１０によれば、測定値に基づき測定対象の状態を評価することができる。 According to the processing device 10 of the present embodiment, the state of the measurement target can be evaluated based on the measurement values.
　例えば、身体の左右に対応して２パターンの測定値が算出された場合、２パターンの測定値の差に基づき測定対象の状態を評価することができる。この場合、身体の左右のバランスが適切な状態か否かを評価することができる。 For example, when two patterns of measured values are calculated corresponding to the left and right sides of the body, the state of the measurement target can be evaluated based on the difference between the two patterns of measured values. In this case, it is possible to evaluate whether the right and left balance of the body is in an appropriate state.
　その他、測定値と参照値との比較結果に基づき、測定対象の状態を評価することができる。この場合、測定対象の状態が一般的な標準状態か否かを評価することができる。 In addition, the state of the measurement target can be evaluated based on the comparison result between the measurement value and the reference value. In this case, it is possible to evaluate whether the state of the measurement target is a general standard state.
　その他、同被験者の測定値と過去の測定値との比較結果に基づき、測定対象の状態を評価することができる。この場合、被験者の測定対象の状態の変化（悪化、現状維持、良化等）を評価することができる。 In addition, the state of the measurement target can be evaluated based on the comparison result between the measurement value of the subject and the past measurement value. In this case, the change (deterioration, maintenance of the current state, improvement, etc.) of the state of the measurement target of the subject can be evaluated.
　このように、本実施形態の処理装置１０によれば、測定対象の状態を様々な角度から評価することができる。 As described above, according to the processing apparatus 10 of the present embodiment, the state of the measurement target can be evaluated from various angles.

　本実施形態の処理装置１０は、測定対象の可動域を測定するための所定の動作を行っている最中に被験者が当該測定の精度に影響する禁止動作を行ったことを検出する機能を有する点で、第１乃至第４の実施形態と異なる。以下、詳細に説明する。 <Fifth embodiment>
The processing device 10 of the present embodiment has a function of detecting that the subject has performed a prohibition operation that affects the accuracy of the measurement while performing a predetermined operation for measuring the movable range of the measurement target. This is different from the first to fourth embodiments. The details will be described below.
　処理装置１０のハードウエア構成の一例は、第１乃至第４の実施形態と同様である。 の 一 An example of the hardware configuration of the processing device 10 is the same as in the first to fourth embodiments.
　処理装置１０の機能ブロック図の一例は、図３５で示される。図示するように、処理装置１０は、選択部１１と、算出部１２と、評価部１３と、出力部１４と、禁止動作検出部１５とを有する。選択部１１、算出部１２、評価部１３及び出力部１４の構成は、第１乃至第４の実施形態と同様である。 An example of a functional block diagram of the processing device 10 is shown in FIG. As illustrated, the processing device 10 includes a selection unit 11, a calculation unit 12, an evaluation unit 13, an output unit 14, and a prohibited operation detection unit 15. The configurations of the selection unit 11, the calculation unit 12, the evaluation unit 13, and the output unit 14 are the same as those of the first to fourth embodiments.
　禁止動作検出部１５は、被験者１００を撮影した画像を解析し、被験者が禁止動作を行ったことを検出する。禁止動作検出部１５は、選択部１１が選択した測定対象に関連した被験者の身体の複数箇所を画像上で特定し、特定した複数箇所に基づき禁止動作を検出する。例えば、禁止動作検出部１５は、身体の第１の箇所と第２の箇所とを結ぶ線と基準線とのなす角が基準範囲から逸脱した場合、禁止動作を行ったと判断してもよい。その他、禁止動作検出部１５は、身体の第３の箇所と第４の箇所との距離が基準範囲から逸脱した場合、禁止動作を行ったと判断してもよい。 (4) The prohibited operation detection unit 15 analyzes an image of the subject 100 and detects that the subject has performed a prohibited operation. The prohibited operation detecting unit 15 specifies a plurality of locations of the subject's body related to the measurement target selected by the selecting unit 11 on the image, and detects the prohibited operation based on the specified plurality of locations. For example, the prohibition operation detection unit 15 may determine that the prohibition operation has been performed when the angle between the line connecting the first and second parts of the body and the reference line deviates from the reference range. In addition, the prohibited operation detection unit 15 may determine that the prohibited operation has been performed when the distance between the third location and the fourth location of the body deviates from the reference range.

Then, the prohibited motion detection unit 15 may grasp the location of the body to be specified based on the information and the measurement target selected by the selection unit 11. Further, the prohibited operation detection unit 15 may grasp the content to be detected based on the information shown in FIG.
　なお、第２の実施形態で説明した通り、算出部１２も、選択部１１が選択した測定対象に関連した被験者の身体の複数箇所を画像上で特定し、特定した複数箇所に基づき所定の処理を行う。しかし、算出部１２が特定する身体の箇所と、禁止動作検出部１５が特定する身体の箇所とは互いに異なり得る（完全には一致しない状態）。すなわち、算出部１２が第１の測定対象に関連して特定する身体の複数箇所と、禁止動作検出部１５が第１の測定対象に関連して特定する身体の複数箇所とは異なり得る（完全には一致しない状態）。 As described in the second embodiment, the calculation unit 12 also specifies a plurality of locations of the subject's body related to the measurement target selected by the selection unit 11 on the image, and performs a predetermined process based on the identified plurality of locations. I do. However, the body part specified by the calculation unit 12 and the body part specified by the prohibited motion detection unit 15 may be different from each other (a state in which they do not completely match). That is, the plurality of parts of the body specified by the calculation unit 12 in relation to the first measurement target may be different from the plurality of parts of the body specified by the prohibited operation detection unit 15 in relation to the first measurement target (completely). Does not match).
　ここで、各測定対象の禁止動作、及び、禁止動作検出部１５が検出する内容の一例を説明する。 Here, an example of the prohibited operation of each measurement target and the contents detected by the prohibited operation detection unit 15 will be described.

The prohibition operation of (1) may be detected by detecting the inclination of a predetermined angle or more.

The unit 15 may analyze the image in real time and detect the prohibited operation. Then, when the prohibited operation detecting unit 15 detects the prohibited operation, the output unit 14 may display a warning to that effect on the screen shown in FIG. 34 in real time.

As described in the second embodiment, the calculation unit 12 analyzes a moving image showing a state in which the subject 100 performs a predetermined series of operations, calculates an angle and a distance made for each frame, and calculates the angle and the distance for each frame. The maximum value among a plurality of angles and distances can be calculated as a measurement value indicating the movable range. In this case, the calculation unit 12 may calculate a maximum value among a plurality of angles and distances calculated from each frame when no prohibited operation is detected as a measurement value indicating the movable range. That is, the calculation unit 12 ignores the angle and distance calculated based on the frame when the prohibited operation is detected, and ignores the angle and distance calculated based on the frame when the prohibited operation is not detected. Based on this, a measurement value indicating the movable range may be calculated.
　以上説明した本実施形態の処理装置１０によれば、第１乃至第４の実施形態と同様な作用効果を実現できる。 According to the processing apparatus 10 of the present embodiment described above, the same functions and effects as those of the first to fourth embodiments can be realized.
　また、本実施形態の処理装置１０によれば、測定対象の可動域を測定するための所定の動作を行っている最中に被験者が当該測定の精度に影響する禁止動作を行ったことを検出できる。このような本実施形態の処理装置１０によれば、可動域の測定結果の信頼度が高まる。 Further, according to the processing device 10 of the present embodiment, it is detected that the subject has performed the prohibition operation that affects the accuracy of the measurement while performing the predetermined operation for measuring the movable range of the measurement target. it can. According to the processing apparatus 10 of the present embodiment, the reliability of the measurement result of the movable range is increased.
＜第６の実施形態＞
　本実施形態の処理装置１０は、反動をつけて動作を行うことで可動域の測定値が大きくなる問題を軽減する機能を有する点で、第１乃至第５の実施形態と異なる。以下、詳細に説明する。 <Sixth embodiment>
The processing apparatus 10 of the present embodiment is different from the first to fifth embodiments in that the processing apparatus 10 has a function of reducing the problem that the measured value of the movable range increases by performing an operation with a recoil. The details will be described below.
　処理装置１０のハードウエア構成の一例は、第１乃至第５の実施形態と同様である。 の 一 An example of the hardware configuration of the processing apparatus 10 is the same as in the first to fifth embodiments.
　処理装置１０の機能ブロック図の一例は、図３、図２７、図２９又は図３５で示される。図示するように、処理装置１０は、選択部１１と、算出部１２とを有し、さらに、評価部１３、出力部１４及び禁止動作検出部１５の中の少なくとも１つを備えることができる。選択部１１、評価部１３、出力部１４及び禁止動作検出部１５の構成は、第１乃至第５の実施形態と同様である。 An example of a functional block diagram of the processing device 10 is shown in FIG. 3, FIG. 27, FIG. 29, or FIG. As illustrated, the processing device 10 includes a selection unit 11 and a calculation unit 12, and can further include at least one of an evaluation unit 13, an output unit 14, and a prohibited operation detection unit 15. The configurations of the selection unit 11, the evaluation unit 13, the output unit 14, and the prohibited operation detection unit 15 are the same as those in the first to fifth embodiments.
　算出部１２は、第２の実施形態で説明した通り、被験者１００が所定の一連の動作を行う様子を示す動画像を解析し、フレーム毎に測定対象の可動域を示す値（なす角や距離）を算出する。そして、算出部１２は、ある瞬間の可動域を示す値として、その瞬間のフレーム及びその直前Ｍ個のフレーム各々に基づき算出した測定対象の可動域を示す値（なす角や距離）の統計値（例：平均値、最頻値、中央値等）を算出する。このようにして、算出部１２は、動画像に含まれる複数の瞬間各々に対応して、その瞬間のフレーム及びその直前Ｍ個のフレームに基づき可動域を示す値を算出する。次いで、算出部１２は、複数の瞬間各々に対応して算出した可動域を示す値の中の最大値を、測定対象の可動域を示す測定値として算出する。 As described in the second embodiment, the calculation unit 12 analyzes a moving image showing a state in which the subject 100 performs a predetermined series of operations, and calculates a value (an angle or a distance) indicating a movable range of a measurement target for each frame. ) Is calculated. Then, the calculating unit 12 calculates, as a value indicating the movable range at a certain moment, a statistical value of a value (an angle or a distance) indicating the movable range of the measurement target calculated based on the frame at the moment and the M frames immediately before the frame. (Example: average value, mode value, median value, etc.) are calculated. In this way, the calculating unit 12 calculates the value indicating the movable range based on the frame at the moment and the M frames immediately before the moment at each of the plurality of moments included in the moving image. Next, the calculation unit 12 calculates the maximum value among the values indicating the movable range calculated corresponding to each of the plurality of instants as a measurement value indicating the movable range of the measurement target.
　なお、上記処理の「その瞬間のフレーム及びその直前Ｍ個のフレーム」を、「その瞬間のフレーム及びその直後Ｍ個のフレーム」又は「その瞬間のフレーム及びその直前直後Ｍ個のフレーム」に代えてもよい。 It should be noted that “the frame at the moment and the M frames immediately before the instant” in the above processing are replaced with “the frame at the instant and the M frames immediately after the instant” or “the frame at the instant and the M frames immediately before and after the instant”. You may.
　算出部１２のその他の構成は、第１乃至第５の実施形態と同様である。 Other configurations of the calculation unit 12 are the same as those of the first to fifth embodiments.
　以上説明した本実施形態の処理装置１０によれば、第１乃至第５の実施形態と同様な作用効果を実現できる。 According to the processing apparatus 10 of the present embodiment described above, the same functions and effects as those of the first to fifth embodiments can be realized.
　また、本実施形態の処理装置１０によれば、反動をつけて動作を行うことで可動域の測定値が大きくなる問題を軽減することができる。反動をつけて第２の実施形態で説明したような動作を行った場合、瞬間的に算出する値（なす角や距離）が大きくなり得るが、その状態は持続しない。このため、連続する複数のフレーム各々から算出した値の統計値を測定値とすることで、瞬間的に大きくなった値を無視又はその影響を小さくすることができる。 According to the processing apparatus 10 of the present embodiment, the problem that the measured value of the movable range is increased by performing the operation with the recoil can be reduced. When the operation described in the second embodiment is performed with a reaction, the values (angles and distances) to be calculated instantaneously may be large, but the state is not maintained. For this reason, by using the statistical value of the value calculated from each of a plurality of continuous frames as the measured value, it is possible to ignore the value that has increased instantaneously or reduce its influence.
