　次に、パター練習システム１の動作について説明する。
　図４は、パター練習システム１の動作のフローチャートである。なお、後述の各処理ステップは、処理内容に矛盾を生じない範囲で、任意に順番を変更して又は並列に実行することができるとともに、各処理ステップ間に他のステップを追加してもよい。また、便宜上１ステップとして記載されているステップは、複数ステップに分けて実行することができる一方、便宜上複数ステップに分けて記載されているものは、１ステップとして把握することができる。 Next, the operation of the putter practice system 1 will be described.
FIG. 4 is a flowchart of the operation of the putter practice system 1. In addition, each processing step to be described later can be executed in any order or in parallel as long as there is no contradiction in processing contents, and other steps may be added between the processing steps. . Further, a step described as one step for convenience can be executed by being divided into a plurality of steps, while a step described as being divided into a plurality of steps for convenience can be grasped as one step.
　まず、図１に示すように端末装置３を台４に固定し、カメラ３１でマット２上のパターン模様２２を撮像する（ステップＳ１１）。
　次に、画像取得部３４１が、カメラ３１で撮像されたパターン模様２２の画像を取得する（ステップＳ１２）。 First, as shown in FIG. 1, the terminal device 3 is fixed to the stand 4 and the pattern pattern 22 on the mat 2 is imaged by the camera 31 (step S11).
Next, the image acquisition unit 341 acquires an image of the pattern pattern 22 captured by the camera 31 (step S12).
　次に、目標位置認識部３４２において、パターン模様２２の画像に基づいて、カップ領域２１の平面位置を認識する（ステップＳ１３）。
　まず、目標位置認識部３４２は、カメラ３１によって取得される画像に投影された座標と、現実世界の座標との変換式を算出する。目標位置認識部３４２は、カメラ３１によって取得した画像の中から少なくとも３つの交点（図２のＰ）を認識し、各点Ｐの情報を用いて以下の変換式（１）を作成する。
ｍ＝ＡＲＭ　…（１）
ここで、Ｍは点Ｐの現実世界の座標ベクトル、ｍはカメラ３１によって取得される画像平面に投影された点Ｐの座標ベクトル、Ｒは変換行列である。最低でも３つの点の情報を用いれば、変換行列Ｒの要素（パラメータ）を算出することができる。 Next, the target position recognition unit 342 recognizes the planar position of the cup area 21 based on the image of the pattern pattern 22 (step S13).
First, the target position recognition unit 342 calculates a conversion formula between coordinates projected on an image acquired by the camera 31 and real-world coordinates. The target position recognizing unit 342 recognizes at least three intersections (P in FIG. 2) from the image acquired by the camera 31, and creates the following conversion formula (1) using information of each point P.
m = ARM (1)
Here, M is a coordinate vector in the real world of the point P, m is a coordinate vector of the point P projected on the image plane acquired by the camera 31, and R is a transformation matrix. If information of at least three points is used, elements (parameters) of the transformation matrix R can be calculated.
　次に目標位置認識部３４２は、得られた変換式を用いて、カメラ３１から取得した画像を、真上方向から見た画像に変換し、表示装置３３に表示する。図５は、変換前の表示装置３３に表示される画面の例を示す図であり、カメラの視点位置からの画像がそのまま表示されている。図６は、変換後の画面表示の例を示す図である。図６では、カップ領域２１を真上から見た画像が表示されている。 Next, the target position recognition unit 342 converts the image acquired from the camera 31 into an image viewed from directly above using the obtained conversion formula, and displays the image on the display device 33. FIG. 5 is a diagram showing an example of a screen displayed on the display device 33 before conversion, and an image from the viewpoint position of the camera is displayed as it is. FIG. 6 is a diagram illustrating an example of the screen display after conversion. In FIG. 6, the image which looked at the cup area | region 21 from right above is displayed.
　次に、プレイヤが、実際のパターゴルフの要領で、カップ領域２１を目標にゴルフクラブでゴルフボールＧ（移動物体）を打つと、画像取得部３４１が、カメラ３１を介してマット２上を移動するゴルフボールＧの画像を取得する。さらに、軌道取得部３４３がゴルフボールＧの軌道を取得する（ステップＳ１４）。
　軌道取得部３４３は、取得した画像全体の中から、色等の情報に基づいてゴルフボールＧに相当しない領域をノイズとして除去し、残った領域をゴルフボールＧとして認識する。さらに、軌道取得部３４３は、所定間隔でゴルフボールＧの領域の中心の座標値を取得し、座標値の集合データをゴルフボールＧの軌道とする。
　なお、ゴルフボールＧの認識には、背景となるマット２の色とのコントラストが強調されるチャネルを使用するのが望ましい。例えば、マット２が青系統の色であれば、Ｂチャネル（青）を使用することにより、白いゴルフボールＧが認識されやすくなる。 Next, when the player hits the golf ball G (moving object) with the golf club with the goal of the cup area 21 in the actual putter golf manner, the image acquisition unit 341 moves on the mat 2 via the camera 31. An image of the golf ball G to be acquired is acquired. Further, the track acquisition unit 343 acquires the track of the golf ball G (step S14).
The trajectory acquisition unit 343 removes a region that does not correspond to the golf ball G as noise from the entire acquired image based on information such as color, and recognizes the remaining region as the golf ball G. Further, the trajectory acquisition unit 343 acquires the coordinate value of the center of the area of the golf ball G at predetermined intervals, and uses the coordinate data of the golf ball G as the trajectory of the golf ball G.
For the recognition of the golf ball G, it is desirable to use a channel in which the contrast with the color of the mat 2 as the background is emphasized. For example, if the mat 2 is a blue color, the white golf ball G can be easily recognized by using the B channel (blue).
　また、ゴルフボールＧによく似た形状の物体（球状の移動物体等）とゴルフボールＧを区別するための仕組みを実装するようにしてもよい。図７は、移動物体がゴルフボールＧであるか否かを判断する具体的な方法を示す図である。図７に示すように、移動物体の画像領域（移動物体とその影を含む、図７の実線で示す領域。移動物体の輪郭は点線で示す。）を矩形で囲ったときの短辺の長さを直径２ｒとし、直径２ｒの値が所定の条件を満たす場合にのみ対象の移動物体をゴルフゴルフボールＧと認識する。判断の条件は、たとえば、２ｒがゴルフボールＧの直径の４分の１～２倍の範囲内とすることができる。 Also, a mechanism for discriminating between the golf ball G and an object having a shape very similar to the golf ball G (such as a spherical moving object) may be implemented. FIG. 7 is a diagram illustrating a specific method for determining whether or not the moving object is the golf ball G. As shown in FIG. 7, the length of the short side when the image area of the moving object (including the moving object and its shadow, the area indicated by the solid line in FIG. 7; the outline of the moving object is indicated by the dotted line) is surrounded by a rectangle. The target moving object is recognized as the golf golf ball G only when the diameter is 2r and the value of the diameter 2r satisfies a predetermined condition. The judgment condition can be, for example, that 2r is in the range of 1/4 to 2 times the diameter of the golf ball G.
　次に、軌道取得部３４３は、ゴルフボールＧの軌道が、カップ領域２１の外縁を通っているか否かを判定する（ステップＳ１５）。カップ領域２１の外縁を通っている場合（ＹＥＳ）には、ステップＳ１６へ進む。一方、カップ領域２１の外縁を通っていない場合（ＮＯ）には、ステップＳ１８へ進む。 Next, the track acquisition unit 343 determines whether or not the track of the golf ball G passes through the outer edge of the cup region 21 (step S15). If it passes through the outer edge of the cup area 21 (YES), the process proceeds to step S16. On the other hand, if the outer edge of the cup region 21 is not passed (NO), the process proceeds to step S18.
　次に、進入方向検出部３４４は、カップ領域２１へのゴルフボールＧの進入方向を検出する（ステップＳ１６）。
　進入方向検出部３４４は、ゴルフボールＧの中心がカップ領域２１の外縁に接した際のゴルフボールＧの進行方向に基づいて、進入方向を決定する。具体的には、図８に示すように、ゴルフボールＧの軌道がカップ領域２１の外縁と最初に交わる点（進入点）を挟む２つの観測点の間を結ぶベクトル（進行方向ベクトルＶ）が、カップ領域２１の外側から内側へ向かう向き（プラスの方向）であるか、内側から外側へ向かう向きであるか（マイナスの方向）を決定する。 Next, the approach direction detection unit 344 detects the approach direction of the golf ball G into the cup region 21 (step S16).
The approach direction detection unit 344 determines the approach direction based on the traveling direction of the golf ball G when the center of the golf ball G is in contact with the outer edge of the cup region 21. Specifically, as shown in FIG. 8, a vector (traveling direction vector V) connecting two observation points sandwiching a point (entrance point) where the trajectory of the golf ball G first intersects with the outer edge of the cup region 21 is obtained. The direction from the outside to the inside of the cup region 21 (positive direction) or the direction from the inside to the outside (negative direction) is determined.
　次に、速度検出部３４５は、カップ領域２１へのゴルフボールの進入速度を検出する（ステップＳ１７）。
　速度検出部３４５は、ゴルフボールＧの中心がカップ領域２１の外縁に接した際のゴルフボールＧの進行方向の速度を進入速度とする。進入速度は、ゴルフボールＧの軌道がカップ領域２１の外縁と最初に交わる点を挟む２つの観測点の間の距離と、２点の観測時間の間隔に基づいて算出する。 Next, the speed detection unit 345 detects the approach speed of the golf ball into the cup area 21 (step S17).
The speed detection unit 345 uses the speed in the traveling direction of the golf ball G when the center of the golf ball G is in contact with the outer edge of the cup region 21 as the approach speed. The approach speed is calculated based on the distance between two observation points that sandwich the point where the trajectory of the golf ball G first intersects with the outer edge of the cup region 21 and the interval between the two observation times.
　次に、進入判定部３４６は、カップ領域２１へのゴルフボールＧの進入方向と進入速度に基づいて、カップ領域２１へのゴルフボールＧの進入の成否（カップインの成否）を判定する（ステップＳ１８）。
　進入判定部３４６は、進入方向と進入速度が所定の条件を満たした場合には、カップイン成功と判定する。例えば、進入方向については、プラスの方向であること、進入速度の範囲としては、時速０．５ｍ以上時速１．５ｍ以下としてもよい。
　進入判定部３４６は、ステップＳ１５でゴルフボールＧの軌道がカップ領域２１の外縁を通っていないと判定された場合、または、ゴルフボールＧの進入方向と進入速度が所定の条件を満たしていない場合には、カップイン失敗と判定する。 Next, the entry determination unit 346 determines whether or not the golf ball G has entered the cup area 21 based on the direction and speed of entry of the golf ball G into the cup area 21 (step in / out of the cup-in) (step S1). S18).
The approach determination unit 346 determines that the cup-in is successful when the approach direction and the approach speed satisfy predetermined conditions. For example, the approach direction may be a positive direction, and the approach speed range may be 0.5 m / h or more and 1.5 m / h or less.
If it is determined in step S15 that the path of the golf ball G does not pass through the outer edge of the cup region 21, or the approach direction and the approach speed of the golf ball G do not satisfy the predetermined conditions. Is determined to be a cup-in failure.
　なお、進入判定部３４６は、カップイン成功と判定する条件をゴルフボールＧのカップ領域２１への進入点の位置に応じて変えるようにしてもよい。例えば、進入点が図６のｃで示す範囲（ゴルフボールＧの軌道の始点側の半円の、中央よりの円弧）、ｓで示す範囲（ゴルフボールＧの軌道の始点側の半円の、端のほうの円弧）、およびｂで示す範囲（ゴルフボールＧの軌道の始点と反対側の半円の円弧）のいずれに含まれるかによって、条件を決定してもよい。図６の例では、範囲ｃに含まれる場合が最も条件が緩く、範囲ｓ、範囲ｂの順に条件が厳しくなるようにしてもよい。 It should be noted that the entry determination unit 346 may change the condition for determining that the cup-in is successful depending on the position of the entry point of the golf ball G into the cup region 21. For example, the range of the entry point indicated by c in FIG. 6 (a semicircle on the start point side of the golf ball G trajectory, an arc from the center), and the range indicated by s (of the semicircle on the start point side of the golf ball G track) The condition may be determined depending on which one is included in the end arc) and the range indicated by b (a semicircular arc opposite to the starting point of the golf ball G trajectory). In the example of FIG. 6, the condition may be the mildest when included in the range c, and the condition may be stricter in the order of the range s and the range b.
　また、進入判定部３４６は、カップ領域２１へのゴルフボールＧの進入方向と、進入速度と、カップ領域２１への進入点に基づいて物理演算を行い、カップインの成否を判定するようにしてもよい。例えば、これらの３つのパラメータに基づいて、ゴルフボールＧのカップへの衝突による軌道変化を計算し、軌道変化後のゴルフボールＧの進行方向と速度に基づいて、カップインの成否を判定するようにしてもよい。 In addition, the entry determination unit 346 performs physical calculation based on the approach direction of the golf ball G into the cup region 21, the approach speed, and the entry point into the cup region 21 to determine whether or not the cup-in is successful. Also good. For example, based on these three parameters, the trajectory change due to the collision of the golf ball G with the cup is calculated, and the success or failure of the cup-in is determined based on the traveling direction and speed of the golf ball G after the trajectory change. It may be.
　また、カップ領域２１へのゴルフボールＧの進入方向の代わりに、進入角度を用いてカップインの成否判定を行うようにしてもよい。
　具体的には、図９に示すように、カップ領域２１の外周の、ゴルフボールＧの中心が乗った位置における接線Ｌと、ゴルフボールＧの進行方向ベクトルＶのなす角度αを進入角度として決定することができる。進入判定部３４６は、カップ領域２１へのゴルフボールＧの進入方向と進入速度に基づいて、カップ領域２１へのゴルフボールＧの進入の成否を判定する。進入判定部３４６は、進入角度と進入速度が所定の条件を満たした場合には、カップインが成功したと判定する。例えば、進入角度の条件は４５度以上１３５度以下などとすることができる。さらに、上記のように、進入点の位置に応じて条件を変えてもよい。また、進入角度と、進入速度と、カップ領域２１への進入点に基づいて物理演算を行い、カップインの成否を判定するようにしてもよい。 In addition, instead of the direction in which the golf ball G enters the cup region 21, the determination of success or failure of the cup-in may be performed using an approach angle.
Specifically, as shown in FIG. 9, the angle α formed by the tangent L at the position where the center of the golf ball G rides on the outer periphery of the cup region 21 and the traveling direction vector V of the golf ball G is determined as the approach angle. can do. The entry determination unit 346 determines whether or not the golf ball G has entered the cup region 21 based on the direction and speed of entry of the golf ball G into the cup region 21. The approach determination unit 346 determines that the cup-in is successful when the approach angle and the approach speed satisfy predetermined conditions. For example, the condition of the approach angle can be 45 degrees or more and 135 degrees or less. Furthermore, as described above, the conditions may be changed according to the position of the entry point. Moreover, physical calculation may be performed based on the approach angle, the approach speed, and the approach point to the cup area 21 to determine whether the cup-in is successful.
　進入判定部３４６によってゴルフボールＧがカップ位置２１へ進入したと判定されると、端末装置３のスピーカから、ゴルフボールＧがカップインしたことを知らせる効果音が出力される。また、ゴルフボールがカップ位置２１へ進入しなかったと判定されると、カップインに失敗したことを知らせる効果音が出力される。また、図１０に示すように、ゴルフボールＧの軌道Ｔが表示装置３３に表示される。 When it is determined that the golf ball G has entered the cup position 21 by the entry determination unit 346, a sound effect informing that the golf ball G has been cup-in is output from the speaker of the terminal device 3. If it is determined that the golf ball has not entered the cup position 21, a sound effect is output to inform that the cup-in has failed. Further, as shown in FIG. 10, the trajectory T of the golf ball G is displayed on the display device 33.
　次に、スコア算出部３４８は、プレイヤのスコアを算出して出力する（ステップＳ１９）。スコアの算出は、カップインの成否、ゴルフボールＧの軌道に基づいて行われる。軌道については、例えば下記の「ナイスイン」または「ナイスタッチ」と判定された場合には、追加のスコアが与えられる。 Next, the score calculation unit 348 calculates and outputs the player's score (step S19). The score is calculated based on the success or failure of the cup-in and the trajectory of the golf ball G. For the trajectory, for example, if it is determined as “Nice in” or “Nice touch” below, an additional score is given.
（ナイスイン判定）
　ゴルフボールＧが所定の条件を満たす軌道を描いてカップインした場合には、「ナイスイン」と判定される。軌道判定部３４７は、図１１に示すように、ゴルフボールＧの軌道全体が、カップ領域２１の中心を通る直線に沿った帯状の領域５１（図中の縦縞で示す領域）内に含まれている場合には、「ナイスイン」と判定する。 (Nice-in judgment)
When the golf ball G cups in while drawing a trajectory that satisfies a predetermined condition, it is determined as “nice in”. As shown in FIG. 11, the track determination unit 347 includes the entire track of the golf ball G within a belt-like region 51 (a region indicated by vertical stripes in the drawing) along a straight line passing through the center of the cup region 21. If it is, “Nice-in” is determined.
（ナイスタッチ判定）
　カップインはしなかったものの、ゴルフボールＧの停止位置（軌道の終点）が所定の条件を満たす領域に含まれる場合には「ナイスタッチ」と判定される。軌道判定部３４７は、図１２に示すように、ゴルフボールＧの予測停止位置が、カップ領域２１のほぼ真後ろで、かつカップ領域２１からの距離が３０～４０ｃｍの領域５２に含まれる場合には、「ナイスタッチ」と判定する。軌道判定部３４７は、ゴルフボールＧがカップ領域２１の外縁を通過した場合にはその時点でゴルフボールＧの予測停止位置を予測する。一方、ゴルフボールＧがカップ領域２１の外縁を通過しなかった場合には、カップ領域２１をゴルフボールＧの軌道の始点側とその反対側の半円に分割する直線を通過した時点でゴルフボールＧの予測停止位置を予測する。この半円に分割する直線の位置は、パターン模様２２の点Ｐとの位置関係に基づいて決定することができる。または、軌道判定部３４７は、移動するゴルフボールＧの画像をカメラ３１で取得できるところまで取得し、最後の画像データを取得した時点でゴルフボールＧの予測停止位置を予測するようにしてもよい。 (Nice touch judgment)
Although the cup-in was not performed, when the stop position (end point of the track) of the golf ball G is included in an area that satisfies a predetermined condition, it is determined as “nice touch”. When the predicted stop position of the golf ball G is included in a region 52 that is substantially behind the cup region 21 and that is 30 to 40 cm from the cup region 21, as shown in FIG. , “Nice touch” is determined. When the golf ball G passes the outer edge of the cup region 21, the track determination unit 347 predicts the predicted stop position of the golf ball G at that time. On the other hand, when the golf ball G does not pass through the outer edge of the cup region 21, the golf ball passes through a straight line that divides the cup region 21 into a semicircle on the golf ball G starting point side and the opposite side. G predictive stop position is predicted. The position of the straight line divided into the semicircles can be determined based on the positional relationship with the point P of the pattern pattern 22. Alternatively, the trajectory determination unit 347 may acquire an image of the moving golf ball G until it can be acquired by the camera 31, and predict the predicted stop position of the golf ball G when the last image data is acquired. .
　予測停止位置は、ゴルフボールＧの予測時点での進行方向や速度の他、予め設定されている地面の摩擦抵抗値に基づいて算出される。なお、マット２をカーペット上に敷いてプレーを行う場合などに、実際の摩擦抵抗がかなり大きくなる場合がある。このような場合、ゴルフボールＧがマット２上で急激に減速し、実際のゴルフボールＧの停止位置が予測停止位置とかけはなれた位置になることがある。このような状況に対応するため、ゴルフボールＧがマット２上で一定値以上減速した場合には、速度の変化に応じて摩擦抵抗値を補正し、予測停止位置を算出するようにしてもよい。このように、実際の停止位置ではなく予測停止位置を用いることで、ゴルフボールＧがカメラ３１で撮影できない位置まで転がっていってしまう場合にも対応できる。 The predicted stop position is calculated based on the ground frictional resistance value set in advance in addition to the traveling direction and speed at the predicted time of the golf ball G. Note that the actual frictional resistance may be considerably increased when playing with the mat 2 placed on the carpet. In such a case, the golf ball G is suddenly decelerated on the mat 2, and the actual stop position of the golf ball G may be different from the predicted stop position. In order to cope with such a situation, when the golf ball G decelerates on the mat 2 by a certain value or more, the frictional resistance value may be corrected according to the change in speed, and the predicted stop position may be calculated. . In this way, by using the predicted stop position instead of the actual stop position, it is possible to cope with a case where the golf ball G rolls to a position where the camera 31 cannot shoot.
（難易度設定）
　次に、コースの難易度設定について説明する。プレイヤは、下記のように、自身の技量等に基づいてコースの難易度を設定することができる。難易度設定部３４９は、プレイヤの入力装置３２を介した指定に基づいて、以下のような難易度設定を行う。 (Difficulty setting)
Next, the course difficulty level setting will be described. As described below, the player can set the degree of difficulty of the course based on his / her skill and the like. The difficulty level setting unit 349 performs the following difficulty level setting based on designation by the player via the input device 32.
（傾斜設定）
　プレイヤが入力装置３２を介してコースの傾斜を設定すると、難易度設定部３４９は、その傾斜に対応したカップインの条件を設定する。具体的には、進入判定部３４６によってカップイン判断の際に使用されるゴルフボールＧの進入方向と進入速度の条件を、傾斜に基づいて設定する。さらに、ゴルフボールＧの軌道も限定するようにしてもよい。例えば、軌道全体が含まれる領域を特定の範囲に限定するようにしてもよい。これにより、実際には傾斜のない場所でも、傾斜があるコースで練習しているのと同じ条件で練習を行うことができる。 (Inclination setting)
When the player sets the inclination of the course via the input device 32, the difficulty level setting unit 349 sets a cup-in condition corresponding to the inclination. Specifically, the approach determination unit 346 sets conditions for the approach direction and the approach speed of the golf ball G used when making a cup-in determination based on the inclination. Furthermore, the trajectory of the golf ball G may be limited. For example, the region including the entire trajectory may be limited to a specific range. Thereby, even in a place where there is no inclination, it is possible to practice under the same conditions as practiced on a course with an inclination.
（ナイスイン・ナイスタッチの条件の難易度設定）
　難易度設定部３４９は、ナイスイン判定やナイスタッチ判定の条件についても、難易度設定を行うことができる。例えば、ナイスイン判定については、帯状の領域５１の幅をより細くすることにより難易度を高くしたり、領域５１を直線ではなくカーブに沿った領域にしたりしてもよい。また、ナイスタッチ判定については、領域５２をより狭い領域に限定するようにしてもよい。また、ナイスイン判定やナイスタッチ判定の難易度を、プレイヤによる傾斜設定に対応させて設定することもできる。 (Nice-in / Nice-touch condition difficulty setting)
The difficulty level setting unit 349 can also set the difficulty level for the conditions of the nice-in determination and the nice touch determination. For example, regarding the nice-in determination, the difficulty may be increased by narrowing the width of the band-shaped region 51, or the region 51 may be a region along a curve instead of a straight line. For nice touch determination, the region 52 may be limited to a narrower region. Also, the difficulty level of the nice-in determination and the nice touch determination can be set in correspondence with the inclination setting by the player.
（カップ領域への進入位置の限定）
　また、難易度設定部３４９は、カップ領域２１へのカップインの条件として、ゴルフボールＧのカップ領域２１への進入位置を限定するようにしてもよい。例えば、ゴルフボールＧがカップ領域２１の外縁のうち、ゴルフボールＧの軌道の始点側の半円の外縁に限定してもよい。なお、この始点側の半円はパターン模様２２の点Ｐとの位置関係に基づいて決定することができる。 (Limited entry position to cup area)
Further, the difficulty level setting unit 349 may limit the entry position of the golf ball G into the cup area 21 as a condition for cup-in to the cup area 21. For example, the golf ball G may be limited to the outer edge of the semicircle on the starting point side of the path of the golf ball G among the outer edges of the cup region 21. The semicircle on the start point side can be determined based on the positional relationship with the point P of the pattern pattern 22.
（変形例１）
　マット２を置く場所は、平らで凹凸のない場所に限られず、傾斜のある場所や凹凸のある地面の上にマット２を置いて練習することもできる。この場合には、カップ領域２１の位置およびゴルフボールの軌道を三次元座標で認識する。なお、傾斜については、端末装置３が有する加速度センサを用いて計測するようにしてもよい。カップイン判定の条件やナイスイン・ナイスタッチの条件は、計測された傾斜や地面の凹凸形状も考慮して設定される。 (Modification 1)
The place where the mat 2 is placed is not limited to a flat and uneven place, and the mat 2 can be practiced by placing it on an inclined place or an uneven ground. In this case, the position of the cup region 21 and the trajectory of the golf ball are recognized by three-dimensional coordinates. Note that the inclination may be measured using an acceleration sensor included in the terminal device 3. The conditions for determining the cup-in and the conditions for the nice-in / nice touch are set in consideration of the measured inclination and the uneven shape of the ground.
（変形例２）
　上記の実施の形態では、カップインしなかった場合にナイスタッチの判定を行うようにしているが、カップインの成否に関わらず、ナイスタッチの判定を行うようにしてもよい。すなわち、カップインの成否に関わらず、ゴルフボールＧがカップ領域２１の外縁を通過した時点またはカップ領域２１を半円に分割する直線を通過した時点、または移動するゴルフボールＧの画像をカメラ３１で最後に取得した時点でゴルフボールＧの予測停止位置を予測し、予測停止位置に基づいてナイスタッチの判定を行ってもよい。これにより、プレイヤはナイスタッチに限定した練習を行うことができる。 (Modification 2)
In the embodiment described above, the nice touch determination is performed when the cup-in is not performed. However, the nice touch determination may be performed regardless of whether the cup-in is successful. That is, regardless of whether the cup-in is successful or not, the camera 31 displays an image of the moving golf ball G when the golf ball G passes the outer edge of the cup region 21 or when it passes a straight line that divides the cup region 21 into a semicircle. Then, the predicted stop position of the golf ball G may be predicted at the time of the last acquisition, and the nice touch may be determined based on the predicted stop position. Thereby, the player can perform practice limited to the nice touch.
　以上のように、本実施形態によれば、端末装置３を用いてマット２上のカップ領域２１の平面位置を認識し、ゴルフボールの軌道、およびカップ領域２１への進入速度と進入方向に基づいて、ゴルフボールのカップ領域２１への進入の成否を判定するようにした。これにより、移動物体を移動させて行う競技の練習を、より現実に近い感覚で行うことができる。 As described above, according to the present embodiment, the terminal device 3 is used to recognize the planar position of the cup area 21 on the mat 2, and based on the path of the golf ball, the approach speed and the approach direction to the cup area 21. Thus, the success or failure of the golf ball entering the cup region 21 is determined. Thereby, the practice of the competition performed by moving the moving object can be performed with a sense closer to reality.
　また、軌道判定部が、ゴルフボールの軌道や予測停止位置に基づいて、ナイスインやナイスタッチなどの判定を行い、スコアに反映させるようにしたので、単なるカップインの練習だけでなく、ナイスインやナイスタッチなど、より実践的な練習も手軽に行うことができる。 In addition, the track determination unit made a determination such as nice-in and nice touch based on the golf ball's track and predicted stop position, and reflected it in the score. More practical exercises such as touch can be done easily.
　また、難易度設定部が、プレイヤが指定したコースの傾斜などに応じてカップインの条件を調整するようにしたので、より実践的で高度な練習も行うことができる。 Also, since the difficulty level setting section adjusts the cup-in conditions according to the slope of the course specified by the player, more practical and advanced practice can be performed.
　なお、本発明は、パターゴルフの練習システムに限らず、ボールなどの移動物体を目標に向けて移動させるゲーム（競技）に適用することができる。例えば、カーリングやボウリング、ビリヤードなどへの適用が考えられる。 Note that the present invention is not limited to a putter golf practice system, and can be applied to a game (competition) in which a moving object such as a ball is moved toward a target. For example, application to curling, bowling, billiards, etc. can be considered.
