Here, the golf course data stores layout information related to the layout and basic direction information related to the launch direction from the tee ground for each hole. The layout information is information indicating the topography of the golf course and the arrangement of each area such as green, pin, fairway, rough, bunker, pond, tree, obstacles, and OB. In the present embodiment, the layout information is described as representing the golf course as 3D model data, but it may be two-dimensional information. The basic direction information indicates the launch direction from the tee ground. The basic direction information is, for example, a recommended direction designated in advance by a golf course manager or the like.

The data stored in the data storage unit 30 is not limited to the above example. For example, when the player inputs a golf club to be used for a tee shot in advance, the data storage unit 30 may store data indicating the input golf club. In addition, for example, the data storage unit 30 stores associations (details will be described later) between the three-dimensional coordinates of the virtual three-dimensional space where the 3D model of the golf course is constructed, and the latitude / longitude information and altitude information of the real space. May be.

[2-2. Flight distance information acquisition unit]
The flight distance information acquisition unit 31 is realized mainly by the control unit 21. The flight distance information acquisition unit 31 acquires flight distance information indicating the relationship between the type of golf club and the flight distance of the hit ball. In the present embodiment, since the flight distance information is stored in the player data, the flight distance information acquisition unit 31 acquires the player data stored in the data storage unit 30. Each player may input his flight distance on the spot. In this case, the flight distance information acquisition unit 31 acquires flight distance information based on the detection signal from the operation unit 24.

[2-3. Type acquisition unit]
The type acquisition unit 32 is realized mainly by the control unit 21. The type acquisition unit 32 acquires the type of golf club used in a shot from a predetermined position based on the player's operation. The predetermined position is a predetermined position in the golf course, and is a tee ground in the present embodiment. Further, in the present embodiment, a case will be described in which each player inputs the type of golf club he / she uses from the operation unit 24 on the spot. For this reason, the type acquisition unit 32 acquires the type of the golf club based on the detection signal of the operation unit 24. Note that the type of golf club may be input in advance by each player. In this case, the type acquisition unit 32 acquires the type of golf club stored in the data storage unit 30.

[2-4. Shot information acquisition unit]
The shot information acquisition unit 33 is realized mainly by the control unit 21. The shot information acquisition unit 33 acquires shot information related to a shot according to a player from a predetermined position in the golf course. The shot information is information indicating the characteristics of the shot of the player, and includes, for example, the flight distance of the hit ball, the jumping direction (angle), the trajectory, the way of bending, and the highest point reached. In the present embodiment, a case where the shot information is a flight distance will be described. For this reason, the shot information acquisition unit 33 relates to the flight distance of the player's shot based on the flight distance information acquired by the flight distance information acquisition unit 31 and the type of golf club acquired by the type acquisition unit 32. Shot information is acquired. That is, the shot information acquisition unit 33 refers to the flight distance information and acquires the flight distance associated with the type of golf club acquired by the type acquisition unit 32 as shot information.

[2-5. Layout information acquisition unit]
The layout information acquisition unit 34 is realized mainly by the control unit 21. The layout information acquisition unit 34 acquires layout information regarding the layout of the golf course. The layout information acquisition unit 34 acquires the golf course data stored in the data storage unit 30.

[2-6. Movement instruction section]
The movement instruction unit 35 is realized mainly by the control unit 21. The movement instructing unit 35 instructs the unmanned aircraft 10 that measures wind to move to a position (hereinafter, referred to as a measurement position) determined based on the shot information acquired by the shot information acquiring unit 33. For example, it is assumed that the association between the shot information and the measurement position is stored in the data storage unit 30. This association may be in a mathematical expression format or a table format. The movement instructing unit 35 instructs the unmanned aircraft 10 to move to the measurement position associated with the shot information. The measurement position is a three-dimensional position in the real space, and is specified by latitude / longitude information and altitude information in this embodiment. The latitude / longitude information is information that specifies the position in the north-south direction and the position in the east-west direction on the earth, and is indicated by numerical values of degrees, minutes, and seconds, for example. The altitude information is information indicating the height from a predetermined position. Here, the altitude information is described as indicating the height from the ground. However, the altitude information may indicate the sea level.

FIG. 7 is an explanatory diagram of a method for determining the measurement position. Here, a case where four players A to D make a tee shot is taken as an example. Note that the Xw-Yw-Zw axis in FIG. 7 is a coordinate axis in the virtual three-dimensional space (the origin is Ow). A 3D model indicated by the layout information is constructed in a virtual three-dimensional space in which the coordinate axes are set. In this embodiment, since the case where the shot information is a flight distance will be described, the movement instruction unit 35 determines the trajectory of the player based on the flight distance of each player and the basic direction V indicated by the basic direction information. Calculate and determine the measurement position. This trajectory is determined without considering the effects of wind. The movement instruction unit 35 determines the measurement position so that the longer the flight distance, the farther and higher from the tee ground, and the shorter the flight distance, the closer the position to the tee ground and lower.

For example, when the player A uses 3rd wood (3W) and the players B to D use the driver (D), as shown in FIG. 4, the flying distances of the players A to D are 200 yards and 160 respectively. Yards, 280 yards and 200 yards. For this reason, when the movement instructing unit 35 calculates the trajectory of each player so as to fly in the basic direction V from the tee ground, the trajectories 50A to 50D shown in FIG. 7 are obtained. The ballistic calculation formula itself may be a formula used in a known golf simulator, for example, a calculation formula for obtaining a parabola by substituting a flight distance. In the present embodiment, this calculation formula corresponds to the association described above.

The movement instruction unit 35 determines the measurement positions of the players A to D based on the three-dimensional coordinates of arbitrary positions on the trajectories 50A to 50D (here, the highest reaching points 51A to 51D). Here, it is assumed that the data storage unit 30 stores the association between the three-dimensional coordinates of the virtual three-dimensional space, the latitude / longitude information, and the altitude information. This association may be in a mathematical expression format or a table format. Based on the association, the movement instruction unit 35 may determine the measurement positions of the players A to D by converting the three-dimensional coordinates of the highest arrival points 51A to 51D into latitude / longitude information and altitude information.

The movement instructing unit 35 instructs the unmanned aircraft 10 to move to the measurement position determined as described above. For example, the movement instruction unit 35 instructs the measurement position by transmitting latitude / longitude information and altitude information to the unmanned aircraft 10. This instruction may be performed by transmitting data in a predetermined format. Further, since the tee shots are performed in a predetermined order, the movement instruction unit 35 specifies the order in which each player makes a tee shot based on the score data, and moves to a measurement position corresponding to the player who will make a tee shot from now on. The unmanned aircraft 10 may be instructed to do so. In order for the movement instruction unit 35 to determine the end of the tee shot of each player, each player may be caused to perform a predetermined operation from the operation unit 24 every time the tee shot is completed. When the tee shot of a certain player is completed, the movement instruction unit 35 instructs the movement of the measurement position according to the next player.

[2-7. Movement control unit]
The movement control unit 36 is realized mainly by the control unit 11. The movement control unit 36 moves the unmanned aircraft 10 based on an instruction from the movement instruction unit 35. For example, the movement control unit 36 adjusts the rotation direction and the rotation speed of each propeller of the unmanned aircraft 10 so as to move toward the measurement position instructed by the movement instruction unit 35. What is necessary is just to adjust the rotation direction and rotation speed of a propeller by changing the parameter which shows these. Various known methods can be applied to the method of moving the unmanned aerial vehicle 10 to the designated measurement position. For example, the movement control unit 36 reduces the rotation speed of the propeller on the traveling direction side. You can do it.

For example, the movement control unit 36 uses the latitude / longitude information (that is, the measurement position) instructed by the movement instruction unit 35 from the latitude / longitude information (that is, the latitude / longitude information of the current position) determined by the reception signal of the GPS sensor of the sensor unit 14. The unmanned aerial vehicle 10 is moved in a direction toward the latitude and longitude information. In addition, for example, the movement control unit 36 adjusts the altitude of the unmanned aircraft 10 so that the difference between the distance from the ground detected by the infrared sensor of the sensor unit 14 and the altitude information is less than a threshold value. When the movement control unit 36 moves the unmanned aerial vehicle 10 to the measurement position, the movement control unit 36 hovers on the spot. In this state, the unmanned aerial vehicle 10 measures the wind using the sensor unit 14 and transmits the measurement result to the player terminal 20.

[2-8. Measurement result acquisition unit]
The measurement result acquisition unit 37 is realized mainly by the control unit 21. The measurement result acquisition unit 37 acquires the measurement result of the wind at the destination (that is, the measurement position) by the unmanned aircraft 10. The measurement result acquisition unit 37 acquires at least one of the wind direction and the wind speed detected by the sensor unit 14 as a measurement result. In this embodiment, although the measurement result acquisition part 37 demonstrates the case where both a wind direction and a wind speed are acquired, you may acquire only any one of a wind direction or a wind speed.

[2-9. Expected part]
The prediction unit 38 is realized mainly by the control unit 21. The prediction unit 38 makes a prediction regarding the trajectory of a shot from a predetermined position based on the shot information acquired by the shot information acquisition unit 33 and the measurement result acquired by the measurement result acquisition unit 37. In this embodiment, the case where the prediction unit 38 predicts the trajectory itself will be described, but only the landing point of the hit ball may be predicted. The trajectory predicted by the prediction unit 38 is a trajectory that takes into consideration the influence of the wind, and is different from the trajectory calculated by the movement instruction unit 35 (the trajectory not considering the wind). As a method for obtaining a trajectory in consideration of the influence of wind, a method used in a known golf simulator may be used. For example, the prediction unit 38 predicts a trajectory as follows.

FIG. 8 is an explanatory diagram of the trajectory predicted by the prediction unit 38. As shown in FIG. 8, in this embodiment, the prediction unit 38 changes the trajectories 50A to 50D calculated by the movement instruction unit 35 based on the wind measurement result. For example, it is assumed that the data storage unit 30 stores the association between the wind measurement result and the change direction and change amount of the trajectory. This association may be in a mathematical expression format or a table format. The prediction unit 38 changes the trajectory calculated by the movement instruction unit 35 by the change direction and change amount associated with the wind measurement result. In other words, the prediction unit 38 changes the trajectories 50A to 50D by the amount corresponding to the wind speed in the direction of the wind direction indicated by the measurement result, so that the expected trajectories 52A to 52D taking into consideration the influence of the wind are obtained. get.

For example, as shown in FIG. 7, since the measurement positions corresponding to the highest arrival points 51A, 51B, 51D are surrounded by trees and are not easily affected by the wind, the measurement result indicates almost no wind. As shown in FIG. 8, the prediction unit 38 acquires predicted

trajectories

52A, 52B, and 52D that do not change so much from the

trajectories

50A, 50B, and 50D. On the other hand, since the measurement position corresponding to the highest arrival point 51C is easily affected by the wind without any obstacles, the prediction unit 38 is expected to have changed greatly from the trajectory 50C. The trajectory 52C is acquired. For example, after the hit ball reaches the highest point, the speed drops and it is easy to bend due to the influence of the wind. Therefore, as shown in FIG. 8, the prediction unit 38 predicts a trajectory 50C that bends greatly in the latter half.

Note that instead of changing the trajectory calculated by the movement instruction unit 35, the prediction unit 38 may recalculate the trajectory from the shot information and the wind measurement result. In this case, it is assumed that the association between the shot information and the wind measurement result and the trajectory is stored in the data storage unit 30. This association may be in a mathematical expression format or a table format. The prediction unit 38 acquires the trajectory associated with the shot information and the wind measurement result as the prediction result.

[2-10. Evaluation Department]
The evaluation unit 39 is realized mainly by the control unit 21. The evaluation unit 39 evaluates the prediction result by the prediction unit 38 based on the layout information acquired by the layout information acquisition unit 34. The evaluation is performed depending on whether a golf penalty occurs or a hit ball lands in a predetermined area. The penalty is determined by the golf rules, and is, for example, OB or water hazard. Predetermined areas include fairways, roughs, bunkers, and ponds. The evaluation unit 39 refers to the layout information to determine whether or not there is an obstacle on the trajectory of the predicted trajectory predicted by the prediction unit 38, or the predicted trajectory landing point predicted by the prediction unit 38 is predetermined. It is judged whether it is an area.

<Evaluation unit 39 makes an evaluation below the standard when a penalty occurs when the expected trajectory is present, when there is an obstacle on the expected trajectory, or when the predicted trajectory is at a rough bunker or pond. On the other hand, when the penalty is not generated in the expected trajectory, when there is no obstacle on the expected trajectory, and when the landing point of the expected trajectory is the fairway, the evaluation unit 39 sets the evaluation to be higher than the standard. In the example of FIG. 8, the

trajectories

52A, 52B, and 52D do not generate a penalty, there are no obstacles on the trajectory, and the landing point is the fairway 53. Therefore, the evaluation unit 39 uses the

trajectories

52A, 52B, and 52D as the reference. The above evaluation is given. On the other hand, there is no penalty on the trajectory 52C and there is no obstacle on the trajectory, but since the landing point is the bunker 54, the evaluation unit 39 gives the evaluation of the trajectory 52C below the standard.

[2-11. Support information provision department]
The support information providing unit 40 is realized mainly by the control unit 21. The support information providing unit 40 provides support information for supporting a shot from a predetermined position to the player based on the measurement result acquired by the measurement result acquisition unit 37.

In the present embodiment, the case where the support information is information indicating the direction or position to be hit by the player will be described. However, the wind direction and the wind speed of the measurement position may be provided as support information, or the method of bending the hit ball ( Hook or slice) or how to hit (such as hitting the top) may be provided as support information. The support information may be provided using an image or sound, but in the present embodiment, the support information is provided using the position of the unmanned aircraft 10. That is, the player takes a shot at the position where the unmanned aircraft 10 is present.

In the present embodiment, the support information providing unit 40 provides support information based on the evaluation result by the evaluation unit 39. For example, the support information providing unit 40 provides as support information whether it is possible to hit in the basic direction V. The basic direction V is described in a course map in the cart, and each player can know the basic direction V. If the evaluation result by the evaluation unit 39 is less than the reference, the support information providing unit 40 provides support information indicating that the basic direction V should not be hit. If the evaluation result by the evaluation unit 39 is greater than or equal to the reference, Support information indicating that the player should strike in the basic direction V is provided.

In the present embodiment, the support information providing unit 40 includes a recommended trajectory acquisition unit 40A. When the evaluation result by the evaluation unit 39 is less than the reference, the recommended ballistic acquisition unit 40A acquires recommended ballistic information regarding the ballistic of the shot to be played by the player based on the measurement result acquired by the measurement result acquisition unit 37. Although the case where the recommended ballistic information indicates the trajectory itself will be described here, the shot launch direction may be the recommended ballistic information. The recommended trajectory information is a trajectory that is evaluated more than the standard, for example, a trajectory that does not cause a penalty, a trajectory that does not have an obstacle on the trajectory, or a trajectory that has a landing point on the fairway.

FIG. 9 is an explanatory diagram of the processing content of the recommended trajectory acquisition unit 40A. As illustrated in FIG. 9, the recommended trajectory acquisition unit 40 A acquires a recommended direction U obtained by rotating the basic direction V by an angle θ corresponding to the measurement result of the measurement result acquisition unit 37, and the flying distance of the player in the direction U The trajectory 55C when the hit ball flies is calculated. For example, it is assumed that the association between the wind measurement result and the recommended direction U is stored in the data storage unit. This association may be in a mathematical expression format or a table format. The recommended trajectory acquisition unit 40A acquires a recommended direction U associated with the wind measurement result, calculates a trajectory 55C, and acquires it as recommended trajectory information.

The recommended trajectory acquisition unit 40A may evaluate the trajectory 55C using the same evaluation method as that of the evaluation unit 39. When the evaluation is less than the reference, the recommended trajectory acquisition unit 40A may change the recommended direction U, recalculate the trajectory 55C, and acquire the recommended trajectory information until an evaluation equal to or higher than the reference is obtained. The support information providing unit 40 provides the recommended ballistic information acquired by the recommended ballistic acquiring unit 40A as support information. The support information providing unit 40 may provide an arbitrary position on the trajectory 55C as support information, or may provide the recommended direction U used when the trajectory 55C is calculated as support information.

In the present embodiment, since support information is provided using the position of the unmanned aircraft 10, the support information providing unit 40 moves to a position determined based on the recommended ballistic information acquired by the recommended ballistic acquisition unit 40A. Thus, the support information is provided by instructing the unmanned aircraft 10. The support information providing unit 40 acquires the three-dimensional coordinates of an arbitrary position (for example, the highest reaching point 56C) on the trajectory 55C, and converts the three-dimensional coordinates into latitude / longitude information and altitude information. The support information providing unit 40 instructs the unmanned aircraft 10 to move to the position indicated by the latitude / longitude information and the altitude information.

Further, in the present embodiment, the support information providing unit 40 provides support information by instructing the unmanned aircraft 10 to stand by at the current position when the evaluation result by the evaluation unit 39 is equal to or higher than the reference. That is, if no problem occurs even if a tee shot is made in the basic direction V, the unmanned aircraft 10 stands by at the measurement position.

[2-12. Evacuation instruction section]
The save instruction unit 41 is realized mainly by the control unit 21. The retreat instruction unit 41 instructs the unmanned aircraft 10 to retreat from the current position after the support information is provided by the support information providing unit 40. The retreat instruction unit 41 may instruct retreat when a predetermined condition is satisfied. For example, the evacuation instruction unit 41 is instructed to evacuate when a certain time has elapsed, when the player starts swinging, when the player takes a shot, or when the player performs a predetermined operation from the operation unit 24. That's fine.

Note that the player's swing or shot may be detected by the detection signal of the sensor unit 14. For example, the retraction instruction unit 41 may analyze an image captured by the image sensor of the sensor unit 14 and determine whether a swing or a shot has been performed. In addition, for example, when the sensor unit 14 includes a microphone, the retraction instruction unit 41 may determine whether a hitting sound is detected. The evacuation instruction performed by the evacuation instruction unit 41 may include the evacuation direction. The retreat direction may be a predetermined direction or may be determined randomly. Furthermore, the unmanned aircraft 10 may analyze the direction of the hit ball, and the retreat direction may be determined based on the direction of the hit ball.

[2-13. Notification section]
The notification unit 42 is realized mainly by the control unit 21. The notification unit 42 notifies the player whether the unmanned aircraft 10 is measuring wind at the destination (measurement position) or whether support information is provided by the position of the unmanned aircraft 10. The notification may be performed visually or audibly. For example, the notification unit 42 displays a predetermined image or outputs a predetermined sound. In addition, for example, when the unmanned aerial vehicle 10 is equipped with a light, the notification unit 42 may perform the notification by instructing the light to be turned on or off. When the notification unit 42 notifies, the player can determine whether or not the shot may be taken.

[3. Processing executed in golf play support system]
FIG.10 and FIG.11 is a flowchart which shows an example of the process performed in a golf play assistance system. The processing illustrated in FIGS. 10 and 11 is executed by the control unit 11 operating according to the program stored in the storage unit 12 and the control unit 21 operating according to the program stored in the storage unit 22. In the present embodiment, the functional blocks shown in FIG. 3 are realized by executing the processing described below.

As shown in FIG. 10, first, in the player terminal 20, the control unit 21 constructs a 3D model of a golf course from which each player will make a tee shot in a virtual three-dimensional space based on the golf course data (S1). ). The control unit 21 may specify a golf course on which each player takes a tee shot by an input from the player, or a GPS sensor is mounted on the player terminal 20 and specified based on the current latitude / longitude information. Also good. In S 1, the control unit 21 constructs the 3D model indicated by the layout information in the storage unit 22.

The control unit 21 specifies the order of tee shots based on the score data (S2). In S 2, the control unit 21 may specify the order so that the scores of the previous holes are in good order. Thereafter, the process for the unmanned aerial vehicle 10 to measure the wind at the measurement position corresponding to the player who will make a tee shot will be executed.

The control unit 21 specifies the type of golf club used by the player (S3). In S 3, the control unit 21 acquires the type of golf club input from the operation unit 24.

The control unit 21 acquires the flight distance when the player uses the golf club specified in S3 based on the flight distance information of the player data (S4). The control unit 21 calculates the trajectory of the player based on the flight distance acquired in S4 and the basic direction V indicated by the basic direction information of the golf course data (S5). In S5, the control unit 21 calculates a trajectory that does not consider the influence of the wind, based on the method described with reference to FIG.

The controller 21 transmits a movement instruction to the unmanned aerial vehicle 10 so as to move to the measurement position determined based on the highest point of trajectory calculated in S5 (S6). Here, since the association between the three-dimensional coordinates of the virtual three-dimensional space, the latitude / longitude information, and the altitude information is stored in the storage unit 22, in S6, the control unit 21 determines the three-dimensional coordinates of the highest arrival point. The latitude / longitude information and altitude information associated with is acquired as a measurement position, and a movement instruction is transmitted.

In the unmanned aerial vehicle 10, when the movement instruction is received, the control unit 11 moves the unmanned aerial vehicle 10 toward the instructed measurement position (S7). In S 7, the control unit 11 sets the latitude / longitude information and altitude information included in the movement instruction as a destination point, and starts the movement of the unmanned aircraft 10.

When the unmanned aircraft 10 moves to the measurement position, the control unit 11 measures the wind direction and the wind speed using the sensor unit 14 (S8). In S8, the control part 11 determines whether it moved to the measurement position using the GPS sensor of the sensor part 14, etc. When it determines with having moved to the measurement position, the control part 11 will acquire the detection result of the wind direction wind speed sensor of the sensor part 14. FIG. The control part 11 transmits the measurement result in S8 to the player terminal 20 (S9). In S 9, the control unit 11 transmits information indicating the wind direction and the wind speed to the player terminal 20.

In the player terminal 20, when the measurement result is received, the control unit 21 corrects the trajectory calculated in S5 based on the measurement result, and acquires the expected trajectory (S10). In S10, based on the method described with reference to FIG. 8, the control unit 21 corrects the trajectory of S5 that does not consider the effect of wind to an expected trajectory that considers the effect of wind.

11, the control unit 21 evaluates the expected trajectory acquired in S10 based on the golf course data (S11). In S 11, the control unit 21 performs evaluation by determining whether a penalty occurs in the predicted trajectory, whether there is an obstacle on the predicted trajectory, and the area where the predicted trajectory is landing.

When the evaluation of the expected trajectory is less than the standard (S11; less than the standard), the control unit 21 acquires a recommended trajectory based on the measurement result received in S10 (S12). In S12, the control unit 21 acquires a recommended trajectory based on the method described with reference to FIG.

The control unit 21 transmits a movement instruction to the unmanned aircraft 10 so as to move on the recommended trajectory acquired in S12 (S13). In S13, the control unit 21 refers to the golf course data, acquires latitude / longitude information and altitude information associated with the three-dimensional coordinates of an arbitrary point on the recommended trajectory, and transmits a movement instruction. . The control unit 21 outputs a predetermined sound such as “The unmanned aircraft moves on the recommended trajectory. When the unmanned aircraft stops, please shot with the unmanned aircraft as a target” (S14).

When the unmanned aircraft 10 receives the movement instruction, the control unit 11 moves toward the recommended trajectory (S15). The control unit 11 retreats after hovering for a certain time (S16). In S16, the control part 11 determines whether it moved on the recommended trajectory using the GPS sensor of the sensor part 14, etc. When it determines with having moved to the measurement position, the control part 11 starts time measurement using a real-time clock etc. while hovering the unmanned aircraft 10. Then, the control unit 11 retracts the unmanned aerial vehicle 10 in a predetermined direction when a certain time has elapsed.

On the other hand, in S10, when the evaluation of the expected trajectory is above the standard (S10; above the standard), the control unit 21 transmits an instruction to the unmanned aircraft 10 to hover for a certain time on the spot (S17). A predetermined voice such as “Shot with unmanned aircraft as a target” is output (S18). When the unmanned aircraft 10 receives the instruction, the unmanned aircraft 10 executes the process of S16 and evacuates after a certain time.

In the player terminal 20, the control unit 21 determines whether the player has made a tee shot based on the input from the operation unit 24 (S19). When it is determined that the player has made a tee shot (S19; Y), the control unit 21 determines whether the tee shot of all the players has been completed based on the number of players stored in the score data (S20). If it is not determined that all the tee shots have been completed (S20; N), the process returns to the process of S3, and a process for assisting the player who makes the next tee shot is executed. On the other hand, when it is determined that all the tee shots have been completed (S20; Y), this process ends.

According to the golf play support system 1 described above, since wind is measured at a measurement position corresponding to each player's shot and support information is provided, accurate support according to the player's shot characteristics can be provided. . For example, when a wind direction and wind speed sensor is arranged at a fixed point on a golf course, only the wind at that location can be measured, which may not be useful information for a player who hits a shot that passes outside that location. In the golf play support system 1, since the unmanned aircraft 10 can measure the wind at an arbitrary position, it is possible to provide useful information according to the player.

Also, in the golf play support system 1, the expected trajectory considering the wind effect at the measurement position is evaluated based on the layout information, so that support information according to the layout of the golf course can be provided to the user.

Further, in the golf play support system 1, when the estimated trajectory considering the influence of wind is low, the recommended trajectory considering the influence of wind is calculated and provided to the player. This can be specifically proposed to the player, and golf play support can be performed more effectively.

Also, in the golf play support system 1, support information is provided by the unmanned aircraft 10 moving on the recommended trajectory, so that the direction in which the player should strike can be visually and easily understood.

Further, in the golf play support system 1, when the evaluation of the predicted trajectory in consideration of the influence of wind is high, there is a problem even if the unmanned aircraft 10 is made to wait at the measurement position and shot in the direction aimed by the player. Can communicate visually that there is nothing.

When providing support information according to the position of the unmanned aircraft 10, the player shots toward the unmanned aircraft 10. However, in the golf play support system 1, the unmanned aircraft 10 evacuates after providing the support information. Therefore, it is possible to prevent the hit ball from hitting the unmanned aircraft 10.

In the golf play support system 1, it is easier for the player to determine whether or not the shot can be made by notifying whether the unmanned aircraft 10 is measuring the wind or telling the player the direction in which the player should hit. .

In addition, although the influence of the wind greatly varies depending on the flight distance of the hit ball, the golf play support system 1 determines the wind measurement position based on the flight distance according to the golf club used by the player. Thus, the accuracy of the support information can be further improved.

[4. Modified example]
The present invention is not limited to the embodiment described above. Modifications can be made as appropriate without departing from the spirit of the present invention.

(1) FIG. 12 is a functional block diagram of the modified example (1). As shown in FIG. 12, in the modified example described below, an obstacle determination unit 43 is realized in addition to the functions of the embodiment. The obstacle determination unit 43 is realized mainly by the control unit 21. The obstacle determination unit 43 determines the presence or absence of an obstacle in the golf course based on the detection result of the sensor unit 14 of the unmanned aircraft 10.

In the modification (1), the unmanned aerial vehicle 10 includes a sensor for detecting an object in the golf course. This sensor may be an infrared sensor or an image sensor. For example, the obstacle determination unit 43 detects an obstacle by determining whether the infrared rays emitted from the infrared sensor are reflected and returned. For example, the obstacle determination unit 43 performs pattern matching between an image captured by the image sensor and an image indicating the basic shape of the obstacle (this image is stored in the data storage unit 30 in advance). To detect obstacles.

The evaluation unit 39 evaluates the prediction result by the prediction unit 38 based on the layout information acquired by the layout information acquisition unit 34 and the determination result of the obstacle determination unit 43. The evaluation method of the evaluation unit 39 is the same as the method described in the embodiment, but the evaluation unit 39 arranges an obstacle in the virtual three-dimensional space based on the determination result of the obstacle determination unit 43. For example, since the unmanned aircraft 10 can acquire latitude / longitude information and altitude information (that is, current flight position) from the GPS sensor and infrared sensor of the sensor unit 14, the evaluation unit 39 calculates the latitude / longitude information and altitude of the unmanned aircraft 10. Information is converted into three-dimensional coordinates in a virtual three-dimensional space. Then, the evaluation unit 39 estimates the positional relationship between the unmanned aircraft 10 and the obstacle from the detection result of the infrared sensor used for the determination by the obstacle determination unit 43 and the image of the image sensor. Determine the coordinates. The evaluation unit 39 arranges a 3D model of the obstacle at the determined three-dimensional coordinates, and determines whether the obstacle is on the redundant trajectory predicted by the prediction unit 38.

According to the modified example (1), since the unmanned aircraft 10 detects an obstacle in the golf course, the expected trajectory can be evaluated in consideration of the obstacle according to the current situation in the golf course.

(2) For example, in the embodiment, the case where the shot information indicates the flight distance has been described, but the shot information may relate to the trajectory of the shot. In this case, the shot information acquisition unit 33 acquires shot information related to the trajectory of the player's shot based on the operation of the player. For example, the player may input the bending state and the jumping direction of his / her shot from the operation unit 24 on the spot, or previously input data may be stored in the player data. The movement instruction unit 35 calculates the trajectory based on the bending condition and the jumping direction input by the player. As described in the embodiment, the calculation method used in a known golf simulator may be used for calculating the trajectory itself.

According to the modified example (2), it is possible to provide support information by measuring the wind at a measurement position corresponding to the trajectory such as the player's shot bending and jumping direction.

(3) For example, the modifications (1) and (2) may be combined.

For example, the measurement position of the unmanned aircraft 10 is not limited to one, and a plurality of measurement positions may be set based on a plurality of positions on the trajectory calculated by the movement instruction unit 35. Furthermore, the number of unmanned aircraft 10 is not limited to one, and a plurality of unmanned aircraft 10 may be used, and the unmanned aircraft 10 may move to each of a plurality of measurement positions. Furthermore, each unmanned aircraft 10 may be arranged so that a plurality of unmanned aircraft 10 shows a recommended trajectory.

For example, although the case where the support information is provided in a scene where the player makes a tee shot has been described, the support information may be provided by executing the same processing in a scene other than the tee shot. In this case, the position of each player's ball is a predetermined position. The position of each player's ball may be estimated by a GPS sensor of a terminal such as a smartphone held by each player, or may be estimated by a GPS sensor of the player terminal 20. In addition, the position of each player may be specified based on an image taken by the unmanned aircraft 10.

Further, for example, since another group may be playing in front of the player, the player terminal 20 causes the unmanned aircraft 10 to photograph the forward direction of the player and, based on this photographed image, drives in the golf course. The prohibited area may be set in the virtual three-dimensional space. When the predicted trajectory enters in this area, the support information providing unit 40 may provide that as support information.

For example, the method of measuring the wind itself may be other than the method using the wind direction and wind speed sensor. For example, the golf play support system 1 may estimate the wind by detecting the distance that the unmanned aerial vehicle 10 is allowed to fall freely and flowed. In addition, for example, various known measurement methods may be used.

Further, for example, in the embodiment, the first half is an uphill, and the middle course and the following is a downhill golf course. However, the golf play support system 1 is applied in a scene of supporting golf play on other various golf courses. Can do. For example, it may be applied to a short hole that can be placed on the green with a single hit, or in a dogleg golf course that bends in a predetermined direction, it can be hit in a direction that crosses an OB or valley area (shortcut) In other words, the player may select whether to strike in a solid direction along the fairway and move the unmanned aircraft 10 to a measurement position corresponding to the direction. In this case, the recommended trajectory acquisition unit 40A may acquire the trajectory to be shortcutted as the recommended trajectory based on the wind measurement result, or may acquire a solid direction as the recommended trajectory for the player aiming for the shortcut. Good.

Also, for example, the layout information may be created in advance by the administrator, or may be generated by the unmanned aircraft 10 shooting the sky over the golf course. Furthermore, the layout information of all holes may be generated when the unmanned aircraft 10 travels over the golf course.

For example, the player terminal 20 may estimate the type of the golf club from the number of remaining yards from a predetermined position where each player takes a shot to the pin. In this case, the golf club used by the player may be estimated using the flight distance information of the player data. Furthermore, the player terminal 20 may suggest a recommended golf club to the player based on the number of remaining yards and the flight distance information.

For example, the function described as being realized by the player terminal 20 may be realized by the unmanned aircraft 10. For example, the data storage unit 30, the flight distance information acquisition unit 31, the type acquisition unit 32, the shot information acquisition unit 33, the layout information acquisition unit 34, the movement instruction unit 35, the measurement result acquisition unit 37, the prediction unit 38, the evaluation unit 39, The support information providing unit 40, the evacuation instruction unit 41, the notification unit 42, and the obstacle determination unit 43 may be realized by the unmanned aircraft 10. In this case, the data storage unit 30 is realized mainly by the storage unit 12, and other functions are realized mainly by the control unit 11. Each function described above may be realized by only the unmanned aircraft 10 or may be shared by each computer of the golf play support system 1. Furthermore, among the functions described above, functions other than the shot information acquisition unit 33, the movement instruction unit 35, the measurement result acquisition unit 37, and the support information provision unit 40 may be omitted.
