Description

The present invention relates to a height difference grasping device for grasping the height difference between arbitrary two points, and a flight distance prediction system for predicting the flight distance of a ball hit by a golf player in consideration of the height difference between two arbitrary points.

As a method for measuring the flight distance of a ball hit by a golf player, there is known a method of calculating the flight distance of the ball from the previous actual hitting position to the new actual hitting position (see, for example, Patent Document 1). .

The flying distance measuring device described in Patent Document 1 includes a receiving unit capable of receiving radio waves (signals) from positioning satellites, and a processing unit capable of calculating the current position (latitude and longitude) based on the radio waves received by the receiving unit. It also has an actual hitting detection section for detecting whether or not the golf player has hit the ball, and a storage section for storing the position at which the ball is hit as the actual hitting position. Then, when the actual hitting detection unit detects that the ball has been hit, the processing unit determines the actual hitting position, and determines the distance from the previous actual hitting position to the new actual hitting position as the flight distance of the ball. It is calculated and stored in the storage unit.

There has also been proposed a golf assisting device that displays the arrival position of the ball, which is used as a guideline for the next play, based on the history of the flight distance of the ball actually hit by the golf player (see, for example, Patent Document 2). ).

The golf assisting device described in Patent Document 2 stores, in storage means, a layout diagram that serves as map information of a golf hole (course), and standard flight distance data for each number obtained from past average flight distances of golf players. When the latitude and longitude of the player's current position are specified by the above-mentioned receiving unit and processing unit, an arc-shaped line centered on the current point is calculated from the data of the standard distance for each club. Then, a group of arcs centered on the current position are superimposed on the layout chart and displayed on the display screen. A group of arcs are displayed concentrically around the current point shown on the layout drawing, so the player can see at a glance which position on the hole (course) the ball will reach.

In Patent Literatures 1 and 2, when the player hits the ball from the current position, the distance to which the ball can be hit can be known in advance from the indication on the display surface. However, the display of the arc group obtained from the data of the standard flight distance does not take into account the height difference of the actual golf hole, but the current point where the ball is hit and the target point where the ball will reach. There is a problem that the greater the difference in altitude, the greater the difference in flight distance when the ball is actually hit compared to the standard flight distance.

In addition, in order to obtain data on the difference in elevation of the actual golf hole as a whole corresponding to the map information of the golf hole, it is necessary to measure the altitude (altitude) individually at each point of the hole, which is a huge amount of time and effort. was not realistic. Moreover, this was a common problem not only for a particular golf hole, but for any target area.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide an elevation difference grasping device capable of obtaining an elevation difference between any two points within a target range without trouble.

Another object of the present invention is to provide a flight distance prediction system capable of correctly correcting and predicting the standard flight distance of a ball hit by a player according to the actual height difference of a golf hole.

In order to achieve the above object, the applicant of the present application has invented a flight distance prediction system equipped with a novel height difference grasping device.

That is, the flight distance prediction system of the present invention acquires mesh altitude data for the entire target range from the base map information issued by the Geospatial Information Authority of Japan, and converts the altitude data into two-dimensional map information for the target range. mesh data acquisition means for generating embedded three-dimensional mesh data; and elevation difference calculation means for calculating, from the three-dimensional mesh data, an elevation difference between one point selected within the target range and another point. , wherein the flight distance prediction system comprises: the height difference grasping device having the target range as a golf hole; Standard flight distance data, which is an average flight distance or a standard flight distance of a ball hit by a golf player from a point, is acquired based on the flight distance history information or the flight distance guide information in the storage unit, and the one point and the data therefrom are obtained. a point specifying means for sending data specifying the other point when the ball reaches the standard flight distance to the elevation difference calculating means; predictive flight distance calculation means for calculating a flight distance that is predicted to actually fly with respect to the standard flight distance based on the elevation difference calculated in step 1, and outputting the calculated result as data as a percentage. characterized by

According to the invention of claim 1, focusing on the fact that the base map information issued by the Geospatial Information Authority of Japan contains mesh elevation data as a digital elevation model, the elevation data is taken in, and a two-dimensional map showing the target range is obtained. If 3D mesh data with elevation data embedded in map information is generated by the mesh data acquisition means, the elevation difference between one point selected within the target range and another point is immediately calculated by the elevation difference calculation means. can. Therefore, it is possible to easily obtain the height difference corresponding to the altitude difference between any two points within the target range. Further, the two-dimensional position of one point in the golf hole where the golf player hits the ball and the two-dimensional position of another point when the ball reaches the standard flight distance from the one point are specified by the point specifying means. Then, the estimated flight distance is obtained by adding the elevation difference calculated by the elevation difference calculation means for the two points and showing the calculated result of the flight distance that is predicted to actually fly with respect to the standard flight distance. It is sent from the calculating means. Therefore, it is possible to correctly correct and predict the standard flight distance of the ball hit by the player according to the height difference of the actual golf hole.

Thereafter, in the same way, the position information for the third, fourth, and so on is acquired, and the carry distances for the second, third, and so on are calculated and stored in the storage section 19 . In the present embodiment, the last swing at position A is determined to be the first shot of player P hitting the ball 7. However, if player P declares in his voice that he will make a shot and then makes a shot, , the sound may be collected by the sound collector 16, and the position information of the position A when the sound is collected may be acquired by the GPS receiver 12, or the player P may operate the operation unit 21 to obtain the position of the position A Information may be acquired by the GPS receiver 12 .

To explain the specific calculation method for the above first shot, as shown in FIG. The position information of L and the right end position R is read from the map information 26A. Then, the middle point of the straight line connecting the left end position L and the right end position R is determined as the center position C of the fairway. If the position B is leftward from the center position C by a predetermined distance (e.g., 2 m) or more, it is determined that the first shot is shifted to the left, and the position B is moved rightward by a predetermined distance (to the left) from the center position C. Similarly to the direction, for example, when the distance is 2 m or more, it is determined that the first shot is shifted to the right. If the position B is less than the predetermined distance from the center position C, it is determined that there is no shift in the first hit. Judgment of deviation in the left-right direction is also performed for the second, third, and so on thereafter.

The corrected flying distance calculation unit 34 compares the altitude of the position A and the altitude of the position B, and calculates the height difference H when there is a difference in altitude. Then, if the position A is lower than the position B as shown in FIG. 5A, it is determined that the shot is an uphill shot, and if the position A is higher than the position B as shown in FIG. Then, it is determined that the shot is downhill, and if there is no altitude difference between positions A and B as shown in FIG. 5C, it is determined that the shot is horizontal. Then, in the case of a launch or a fall, based on the height difference H, a correction flight distance is calculated from the actual flight distance by a predetermined calculation formula assuming that there is no elevation difference H between the positions A and B. If the ball is determined to be horizontal, the actual flight distance is set as the corrected flight distance.

In the present embodiment, a swing in which the peak GP2 of the three-axis synthetic acceleration of the hip Pk occurs temporally earlier than the peak GP1 of the three-axis synthetic acceleration of the left wrist Pw is considered to be valid. If the peak GP1 occurs temporally earlier than the peak GP2, or if the time difference t between the peak GP1 and the peak GP2 is 0, it is assumed that there is no charge. Also, the time difference t when there is a charge within the time difference t is referred to as the charge time T. It should be noted that FIG. 8 shows the three-axis synthetic acceleration of the left wrist Pw and hip Pk in a swing with charge.

As for the speed of the hip Pk, the average speed in the swing, the speed per unit time at the moment of the impact P4, and the like are calculated.

Further, as shown in FIG. 7, the analysis unit 62 includes an inclination calculation unit 66. The inclination calculation unit 66 calculates the wristwatch-type terminal 2, and by extension, The tilt of the left wrist Pw of the player P is calculated as angles in three axial directions. The inclination of the left wrist Pw is calculated at each of the stationary state P1 at address, P2 during the backswing (the left wrist Pw starts to become light), top P3, impact P4, follow P5, and finish P6. For example, the tilts of the left wrist Pw in the stationary state P1 of address in this embodiment are θx=5.5, θy=42.5, and θz=−21.1.

Further, the tilt calculation unit 66 calculates the tilt of the waist Pk of the player P as angles in the three-axis directions based on the three-axis synthetic acceleration information of the waist Pk of the player P.

The hole map information 26A displayed on the display unit 20 is displayed in color, and the tee ground S1, fairway S2, rough S3, bunker S4, pond S5, and green S6 are displayed in different colors. is easy to visually confirm.

When the player P's shot is input to the wristwatch-type terminal 2 by voice or operation of the operation unit 21, the advice calculation unit 37 calculates the shot of the player P as one point from the position information of the player P and the map information 26A. The planned position and the distance to the fairway S2 and green S6 are calculated. Further, the flight distance history information 26B is read from the storage unit 19, the average flight distance and the average corrected flight distance of the player P are calculated therefrom, and the number of the recommended club 6 suitable for the distance to the fairway S2 and the green S6 is presented. do. At this time, the past average distance of the player P corresponding to the number of the recommended club 6 is displayed on the display unit 20 as an arc line 68 and a numerical value 69 superimposed on the hole map information 26A (see FIG. 2). .

The advice calculation unit 37 also calculates the rate and tendency of deviation in the left-right direction of the shot of the player P when using the recommended club 6 . The advice calculation unit 37 reads out the ratio of the lateral deviation of the shot of the player P from the storage unit 19 and presents it on the display unit 20 or the notification unit 22 . As for the method of presenting the deviation in the horizontal direction, the percentage of deviation may be displayed on the display unit 20, or may be reported by the notification unit 22 by voice. , the tendency may be displayed on the display unit 20 with words such as "65% deviation to the left, caution!"

In addition, the advice calculation unit 37 calculates the average length of the charge time T of the player P's past shots that flew long distances and shots that did not shift in the left-right direction, the acceleration, speed, and inclination of the left wrist Pw. , the acceleration, velocity, and inclination of the waist Pk, and display the results on the display unit 20 or notify the result by the notification unit 22. FIG.

Also, if the next shot by the player P will be an uphill shot or a downhill shot, and if the height difference H is known in advance, that fact is sent to the wristwatch-type terminal 2 by voice or operation of the operation unit 21. By inputting, the corrected flight distance history information 26B stored in the storage unit 19 is read out, and the past average flight distance corresponding to the height difference H at the time of launch or downhill of the player P is calculated therefrom. , can also be displayed on the display unit 20 .

In addition, the state of the shot point (tee ground S1, fairway S2, rough S3, bunker S4, pond S5, uphill slope, downhill slope, wind strength, wind direction, etc.) can be set by voice or operation of the operation unit 21. By inputting to the terminal 2, the corrected flight distance history information 26B stored in the storage unit 19 is read out, the past average flight distance corresponding to the state of the player P is calculated therefrom, and displayed on the display unit 20. You can also

The advice information calculated by the advice calculation unit 37 is calculated based on the information stored in the storage units 19 and 56. For example, from the distance information of past shots included in the corrected distance history information 26B, The average flight distance may be calculated from the flight distance information or the corrected flight distance information excluding the information of failed shots with extremely short actual flight distances, and the result may be displayed on the display unit 20 or the notification unit 22 .

Further, the advice calculation unit 37 monitors the heart rate of the player P based on the pulse wave information from the heart rate measurement unit 17, and displays advice according to the heart rate on the display unit 20 or notifies it by the notification unit 22. can do. For example, when the advice calculation unit 37 acquires acceleration information from the first accelerometer side unit 11 and position information from the GPS reception unit 12, and determines that the player P has shot at a specific position (for example, inside a bunker). Furthermore, based on the pulse wave information from the heart rate measuring unit 17, if the heart rate of the player P rises above a predetermined value before and after the shot, the player will say, "You did your best (escape from the bunker)." A message of encouragement is notified from the notification unit 22. - 特許庁As a result, the motivation of the player P is increased, and it becomes possible to continue the play happily.

Next, the configuration and operation of each section when the control means 10 reads the flight distance prediction program from the storage section 19 will be described.

In FIG. 3, the control means 10 has a function as an elevation difference grasping section 40 for grasping the elevation difference between arbitrary two points in the two-dimensional map information 26A stored in the storage section 19. The height difference grasping unit 40 accesses a server (not shown) connected to the network 63 in cooperation with the mobile terminal 3, and extracts the map information from the base map information of the Geospatial Information Authority of Japan stored in the server. For the entire golf hole that is the target range included in 26A, 5m mesh altitude data is acquired from the transmitting/receiving unit 55 of the mobile terminal 3 via the communication means 9, and the altitude data is stored in the golf hole map information 26A. The mesh data acquisition unit 38 that embeds and generates unique three-dimensional mesh data of latitude, longitude, and altitude, and the altitude of one point with specified latitude and longitude in the golf hole included in the map information 26A and an elevation difference calculation unit 39 that calculates the difference from the elevation of another point using the three-dimensional mesh data generated by the mesh data acquisition unit 38 . After generating the three-dimensional mesh data described above, the mesh data acquisition unit 38 preferably stores this in the storage unit 19 as the mesh information 26C. As a result, the altitude difference calculation unit 39 can read out the mesh information 26C stored in the storage unit 19 and calculate the altitude difference between one point and another point. This eliminates the need for the mesh data acquisition unit 38 to generate three-dimensional mesh data each time the difference is calculated.

The control means 10 also has the functions of a point identification section 41 and a predicted flying distance calculation section 42 in addition to the height difference grasping section 40 . The point specifying unit 41 acquires the position information from the GPS receiving unit 12, specifies the two-dimensional position of one point where the player P will shoot from now on, and then the club 6 recommended by the player P from the one point. Standard flight distance data, which is the average flight distance when the ball 7 is hit with a count of , is acquired from the flight distance history information 26B of the storage unit 19, and when the ball 7 reaches the standard flight distance from one point. After specifying the two-dimensional positions of the other points, the data of the two-dimensional positions of these two points are sent to the elevation difference calculation unit 39 . Upon receiving this data, the altitude difference calculator 39 starts to calculate the altitude difference between the above-described one point and another point.

Predicted flight distance calculation unit 42 predicts actual flight with respect to the standard flight distance based on the altitude difference calculated by altitude difference calculation unit 39 using the data specifying the two points sent from point specification unit 41. The flying distance (predicted flying distance) to be projected is calculated, and the calculation result is output as data. Here, as the altitude of the other point is lower than the altitude of the one point, it is predicted that the downhill shot from the first point will be longer, so the predicted flight distance is calculated to be longer than the standard flight distance. Conversely, as the altitude of the other point becomes higher than the altitude of the one point, it is predicted that the shot from the one point will be shorter in launch, so the predicted flight distance is calculated to be shorter than the standard flight distance.

FIG. 9 shows an example of an aerial photograph taken of the entire golf course and elevation data superimposed thereon. In the figure, the symbol X is a golf course photographed by an aerial photograph, and based on the aerial photograph of this golf course X, the designed map information 26A for each hole as shown in FIGS. 2 and 4 is prepared in advance. be done. Symbol Y indicates an area where 5-m mesh elevation data can be acquired in the base map information issued by the Geospatial Information Authority of Japan. This 5m mesh altitude data can be acquired by the mesh data acquisition unit 38 of the height difference grasping unit 40 accessing a server connected to the network 63 . In addition to the 5m mesh, 10m mesh elevation data is also prepared for the basic map information, but it is preferable to use the 5m mesh elevation data, which has finer data.

The mesh data acquisition unit 38 acquires the elevation data of the entirety of the thick frame including the entirety of the golf course X from the server connected to the network 63 via the portable terminal 3 . Here, the elevation of the 5m mesh within the four two-dimensional regions of "15/29021/12666", "15/29022/12666", "15/29021/12667", and "15/29022/12667" All of the data is acquired, and using the acquired altitude data, three-dimensional mesh data consisting of latitude, longitude and altitude at 5m intervals corresponding to each hole of the map information 26A is created. The three-dimensional mesh data created by the mesh data acquisition unit 38 is stored in the storage unit 19 as mesh information 26C in association with the map information 26A of each hole.

FIG. 10 shows an enlarged view of the entire specific hole Xh in the golf course X shown in FIG. In the figure, reference YL indicates a 5m mesh line. The mesh data acquisition unit 38 acquires elevation data of 5m mesh for each hole Xh of the golf course X, and converts the two-dimensional map information 26A in which each hole Xh is designed into three-dimensional data including the elevation. Mesh data is created and stored in the storage unit 19 as mesh information 26C. This mesh information 26C includes elevation data at each point at intervals of 5 m for the entire hole Xh.

FIG. 11 shows the elevation of each point Yp included in the mesh information 26C at specific locations within the hole Xh. In the figure, the numbers shown at each point Yp indicate the altitude (unit: meter) of that point Yp. Although not shown, the latitude and longitude of each point Yp are also included in the mesh information 26c along with the altitude. By reading out the mesh information 26c from the storage unit 19, the elevation difference calculator 39 can calculate the elevation difference between any two points Yp1 and Yp2 in the hole Xh using the mesh information 26c. For example, the altitude difference between one point Yp1 and another point Yp2 is the difference between the altitude of one point Yp1 "16.71" meters and the altitude of the other point Yp2 "18.53" meters, that is, 18.53- It can be calculated as 16.71 = 1.82 meters. In addition, since the mesh information 26c also includes latitude and longitude information, the elevation difference calculator 39 calculates in what direction and with what elevation difference the ground S is inclined from one point Yp1. can also be grasped.

When the player P hits the ball 7 from one point Yp1, the height difference (height difference) calculated by the height difference grasping unit 40 is calculated by calculating the height difference between the point Yp2 and the other point Yp2 specified from the standard flight distance of the player P. It can be used to calculate the predicted flight distance that takes into account the difference.

FIG. 12 shows an example of height difference expression using altitude data displayed on the display unit 20 in the flight distance prediction system 1 of the present embodiment. As described above, when player P inputs a shot into the wristwatch type terminal 2 by voice or operation of the operation unit 21, the advice calculation unit 37 acquires the position information of the player P from the GPS reception unit 12, is superimposed on the map information 26A of the hole including to display. The number of the recommended club 6 is automatically set by the advice calculator 37 according to the relationship between the position of the player P and the positions of the fairway S2 and the green S6 included in the map information 26A.

At this time, the point specifying unit 41 specifies the position information from the GPS receiving unit 12 fetched by the advice calculating unit 37 as the two-dimensional position of the point Yp1 where the player P will next shoot. Based on the average flight distance calculated in (1), a point at which the ball 7 reaches the center position C of the fairway S2 or the green S6 when hit with the average flight distance from one point Yp1 is specified as another point Yp2. The two-dimensional positions of the points Yp1 and Yp2 are sent to the altitude difference calculator 39 . Note that the point identification unit 41 may have the function of the advice calculation unit 37 as described above.

When the point identification unit 41 identifies the two-dimensional positions of one point Yp1 and another point Yp2, the elevation difference calculation unit 39 calculates the elevation difference between the two points Yp1 and Yp2 and sends it to the predicted flying distance calculation unit 42. do. In response to this, the predicted flight distance calculation unit 42 adds the height difference acquired from the altitude difference calculation unit 39 to the average flight distance displayed as the arc line 68 on the display unit 20, A projected flying distance is calculated, and the calculation result is displayed as a percentage 71 near the center position C of the fairway S2 where the arc line 68 intersects. As a result, it becomes possible to correctly correct and predict the average flight distance of the ball 7 hit by the player P according to the height difference of the ground S in the actual hole, and display it on the display unit 20, for example, as a percentage of 71. Thus, the player P can accurately predict the flight distance of the ball 7.

In the example shown in FIG. 12, when the player P inputs to the wristwatch-type terminal 2 that he or she will shoot on the tee ground S1 of the course displayed on the display unit 20, the point specifying unit 41 selects one point on the tee ground S1. The latitude and longitude of the point Yp1 are specified, and the latitude and longitude of another point Yp2 that reaches the center position C of the fairway S2 when the player P hits the ball 7 from the point Yp1 with an average flying distance is specified. Then, these data are sent to the altitude difference calculator 39 . The altitude difference calculation unit 39 acquires the altitude data at the point closest to that position from the latitude and longitude of one point Yp1 from the mesh information 26C of the storage unit 19, and from the latitude and longitude of another point Yp2, The altitude data at the point closest to the position is acquired from the mesh information 26C of the storage unit 19, and the difference is calculated.

As an example, it is assumed that the past average flight distance when the player P hits the ball 7 from the point Yp1 with the club 6 of the recommended number is 215 yards. At this time, if the altitude of the point closest to one point Yp1 is 240 meters and the altitude of the point closest to the other point Yp2 is 270 meters, the altitude difference calculation unit 39 determines that the target The elevation difference with the other point Yp2 is calculated to be 30 meters uphill (-30m). In response to this calculation result, the predicted flight distance calculation unit 42 causes the display unit 20 to display in percentage 71 that the predicted flight distance is 95% of the average flight distance of 215 yards.

Note that the predicted flight distance calculation result by the predicted flight distance calculation unit 42 may be output to the notification unit 22 instead of the display unit 20 . In this case, the notification unit 22 can issue an announcement such as "It is predicted that the flight distance will be 95% of the average flight distance." Also, instead of the percentage, the predicted flight distance itself (for example, “204 yards” corresponding to 215×95%) may be directly displayed or notified.

As described above, the height difference grasping unit 40, which is the height difference grasping device of the present embodiment, acquires 5m mesh elevation data for the entire golf hole as the target range from the base map information issued by the Geospatial Information Authority of Japan. and embeds the altitude data in the two-dimensional map information 26A showing the golf holes to generate three-dimensional mesh data having latitude, longitude and altitude. and an elevation difference calculation unit 39 as elevation difference calculation means for calculating the elevation difference between one point Yp1 and another point Yp2 selected in the golf hole of the map information 26A from three-dimensional mesh data. I have.

Focusing on the fact that the base map information issued by the Geospatial Information Authority of Japan contains mesh elevation data as a digital elevation model, the elevation data is incorporated into two-dimensional map information 26A indicating, for example, a golf hole as a target range. If three-dimensional mesh data in which elevation data is embedded is generated by the mesh data acquisition unit 38, the elevation difference between one point Yp1 and another point Yp2 selected in the golf hole of the map information 26A is calculated as the elevation difference. It can be calculated immediately by the calculation means 39 . Therefore, between any two points Yp1 and Yp2 within the object range, the height difference corresponding to the altitude difference can be obtained without trouble.

Further, the flight distance prediction system 1 of the present embodiment, in addition to the above-described height difference grasping unit 40 whose target range is a golf hole, is the golf player P from one point Yp1 within the golf hole shown in the map information 26A. obtain data of the standard flight distance, which is the average flight distance of the ball 7 hit by the altitude Based on the elevation difference calculated by the elevation difference calculation unit 39, using the point identification unit 41 as point identification means that is sent to the difference calculation unit 39 and the data that identifies each of the points Yp1 and Yp2 sent from the point identification unit 41 a predicted flight distance calculation unit 42 as predicted flight distance calculation means for calculating a predicted flight distance that is predicted to actually fly with respect to the standard flight distance, and outputting the calculated result to the display unit 20 or the like as data; , is incorporated in the wristwatch-type terminal 2 as a terminal carried by the player P.

In this case, in the golf hole shown in the map information 26A, the two-dimensional position of one point Yp1 where the player P hits the ball 7, and another point Yp2 when the ball reaches the standard flight distance from the one point Yp1. If the two-dimensional positions are specified by the point specifying unit 41, the altitude difference calculated by the altitude difference calculating unit 39 for the two points Yp1 and Yp2 is taken into account, and the actual flight distance is calculated based on the standard flight distance. Data indicating the calculation result of the predicted flying distance is sent from the predicted flying distance calculator 39 . Therefore, it is possible to correctly correct and predict the standard flight distance of the ball 7 hit by the player P according to the actual height difference of the golf hole.

The point identification unit 41 of the present embodiment performs a tap operation on a specific point on the surface part 32E of the display unit 20 on which the map information 26A is displayed. After the dimensional position is specified, the target flight distance from the one point Yp1 is acquired from the target flight distance information 26D in the storage unit 19, and the standard flight distance from the one point Yp1 is obtained. After identifying the two-dimensional position of the other point Yp2 when the ball 7 arrives, the data of the two-dimensional positions of these two points Yp1 and Yp2 are sent to the elevation difference calculator 39. FIG. Upon receiving this data, the altitude difference calculator 39 starts to calculate the altitude difference between the above-described one point and another point.

Predicted flight distance calculation unit 42 predicts actual flight with respect to the standard flight distance based on the altitude difference calculated by altitude difference calculation unit 39 using the data specifying the two points sent from point specification unit 41. The flying distance (predicted flying distance) to be projected is calculated, and the calculation result is output as data. Here, as the altitude of the other point is lower than the altitude of the one point, it is predicted that the downhill shot from the first point will be longer, so the predicted flight distance is calculated to be longer than the standard flight distance. Conversely, as the altitude of the other point becomes higher than the altitude of the one point, it is predicted that the shot from the one point will be shorter in launch, so the predicted flight distance is calculated to be shorter than the standard flight distance.

In the present embodiment, the procedure for the elevation difference grasping unit 40 to calculate the elevation difference between any two points Yp1 and Yp2 using the mesh information 26c is as follows. It is completely the same as the first embodiment except that it is obtained from the cart management device 78 instead of 3. Here, the identification of the two points Yp1 and Yp2 by the point identification unit 41 is different from that in the first embodiment.

FIG. 15 shows an example of height difference expression using altitude data displayed on the display unit 20 in the flight distance prediction system 1 of the present embodiment. In the figure, when position information indicating the current position of the golf cart 75 is taken in from the GPS receiver 12 to the control means 10, the control means 10 outputs the map information 26A including the golf course closest to the current position of the golf cart 75. is displayed on the display unit 20 . In this state, when the player P riding in the golf cart 75 performs a tap operation on the surface portion 32E of the display portion 20, he can arbitrarily select the shot position where the shot is to be made.

When a tap operation is performed on the surface portion 32E of the display unit 20, the position specifying unit 41 changes the point of the map information 26A corresponding to the tapped position to a point Yp1 which is the intended shot position of the player P. Identify as Further, the position specifying unit 41 acquires the target flight distance from the point Yp1 from the target flight distance information 26D of the storage unit 19, and sets the ball to the standard flight distance, which is the target flight distance from the one point Yp1. The point reached by 7 is specified as another point Yp2. Data on the two-dimensional positions of the two specified points Yp1 and Yp2 are sent from the position specifying unit 41 to the elevation difference calculating unit 39, and the target distance is calculated as a circle centered on the intended shot position of the player P. The arc (radar) 68 is displayed on the display unit 20 .

Subsequent procedures are the same as in the first embodiment. That is, when the point specifying unit 41 specifies the two-dimensional positions of one point Yp1 and another point Yp2, the elevation difference calculating unit 39 calculates the elevation difference between the two points Yp1 and Yp2, and the predicted flight distance calculating unit 42 send to In response to this, the predicted flight distance calculation unit 42 adds the height difference acquired from the altitude difference calculation unit 39 to the target flight distance displayed as the arc line 68 on the display unit 20, and calculates the actual ball 7. A flying distance that the ball is expected to fly is calculated, and the calculation result is displayed as a percentage 71 near the center position C of the fairway S2 where the arc line 68 intersects. As a result, it becomes possible to correctly correct and predict the average flight distance of the ball 7 hit by the player P according to the height difference of the ground S in the actual hole, and display it on the display unit 20, for example, as a percentage of 71. Thus, the player P can accurately predict the flight distance of the ball 7.

In the example shown in FIG. 15, when the player P performs a tap operation on the surface portion 32 of the display unit 20 on the tee ground S1 of the course displayed on the display unit 20, the point specifying unit receives the operation signal from the operation unit 21. 41 identifies the latitude and longitude of one point Yp1 on the tee ground S1 corresponding to the position of the tapping operation. Next, the point identification unit 41 acquires the data of the flight distance, which is a guideline when the player P hits the ball 7 from the shot position that is the one point Yp1, from the flight distance guideline information 26D of the storage unit 19 . Here, corresponding to the position of one point Yp1 on the tee ground S1, three target distances of "150Y (yards)", "200Y", and "250Y" are read out, each of which is a golf hole. are displayed on the display unit 20 as concentric arc lines 68-1, 68-2, and 68-3 superimposed on the map information 27A.

Then, the point specifying unit 41 determines the latitude and longitude of another point Yp2-1 that reaches the center position C of the fairway S2 when the player P hits the ball 7 from the point Yp1 with a target flight distance of "150Y". Similarly, when the player P hits the ball 7 from one point Yp1 with a target flight distance of "200Y", the latitude and longitude of another point Yp2-2 that reaches the center position C of the fairway S2 is specified, and the latitude and longitude of another point Yp2-3 that reaches the center position C of the fairway S2 when the player P hits the ball 7 from one point Yp1 with a target flight distance of "250Y" is specified. Then, these data are sent to the altitude difference calculator 39 . From the latitude and longitude of one point Yp1, the altitude difference calculation unit 39 acquires the altitude data at the point closest to that position from the mesh information 26C of the storage unit 19, and corresponds to the target flight distance of "150Y". Based on the latitude and longitude of the other point Yp2-1, the altitude data at the point closest to that position is acquired from the mesh information 26C of the storage unit 19, and the difference between the one point Yp1 and the other point Yp2-1 is calculated. calculate. Similarly, the altitude difference calculation unit 39 obtains the altitude data at the point closest to that position from the latitude and longitude of the other point Yp2-2 corresponding to the target flight distance of "200Y" from the mesh information 26C of the storage unit 19. and calculate the difference between one point Yp1 and another point Yp2-2, and from the latitude and longitude of another point Yp2-3 corresponding to the target flight distance of "250Y", the point closest to that position is acquired from the mesh information 26C of the storage unit 19, and the difference between one point Yp1 and another point Yp2-32 is calculated.

For example, the altitude difference calculator 39 determines that the point closest to one point Yp1 has an altitude of 240 meters, and the point closest to another point Yp2-1 corresponding to the target flight distance of "150Y" has an altitude of 250 meters. Assuming that there is, it is calculated that the elevation difference from the point Yp1 to the point Yp2-1, which is the target, is 10 meters uphill (-10m). In response to this calculation result, the predicted flight distance calculation unit 42 causes the display unit 20 to display that the estimated flight distance is 98% of the standard flight distance of "150Y" at a percentage of 71-1. .

Similarly, if the altitude of the point closest to the other point Yp2-2 corresponding to the target flight distance of "200Y" is 270 meters, the elevation difference calculation unit 39 determines that the point Yp1 is the target when viewed from the point Yp1. Elevation difference with point Yp2-2 is calculated to be 30 meters uplift (-30m). In response to this calculation result, the predicted flight distance calculation unit 42 causes the display unit 20 to display that the estimated flight distance is 95% of the standard flight distance of "200Y" as a percentage of 71-2. .

Further, if the altitude of the point closest to the other point Yp2-3 corresponding to the target flight distance of "250Y" is 215 meters, the altitude difference calculation unit 39 determines that the other point Yp1 that is the target when viewed from the point Yp1 is 215 meters above sea level. Elevation difference with point Yp2-3 is calculated to be 25 meters downhill (+25m). In response to this calculation result, the predicted flight distance calculation unit 42 causes the display unit 20 to display that the estimated flight distance is 110% of the standard flight distance of "250Y" as a percentage of 71-3. .

In the present embodiment as well, the predicted flight distance calculation result by the predicted flight distance calculation unit 42 may be output to the notification unit 22 instead of the display unit 20 . Also, instead of the percentage, the predicted flight distance itself may be directly displayed or notified.

As described above, the elevation difference grasping unit 40 of the present embodiment also obtains 5m mesh elevation data for the entire target range golf hole from the base map information issued by the Geospatial Information Authority of Japan, and converts the elevation data to A mesh data acquisition unit 38 for embedding golf holes in two-dimensional map information 26A to generate three-dimensional mesh data having latitude, longitude, and altitude; An elevation difference calculation unit 39 is provided for calculating the elevation difference between the one point Yp1 and the other point Yp2 from three-dimensional mesh data.

Therefore, if the mesh data acquisition unit 38 generates three-dimensional mesh data in which altitude data is embedded in the two-dimensional map information 26A indicating, for example, a golf hole as a target range, the selected area within the golf hole of the map information 26A can be generated. The elevation difference between one point Yp1 and another point Yp2 can be immediately calculated by the elevation difference calculation means 39, and the elevation difference between any two points Yp1 and Yp2 within the target range can be obtained without trouble.

Further, the flight distance prediction system 1 of the present embodiment, in addition to the height difference grasping unit 40 whose target range is a golf hole, is the golf player P hitting from one point Yp1 within the golf hole shown in the map information 26A. Standard flight distance data, which is a reference flight distance of the ball 7, is acquired, and data specifying one point Yp1 and another point Yp2 from which the ball 7 reaches at the standard flight distance is used to calculate the difference in elevation. Based on the elevation difference calculated by the elevation difference calculation section 39 based on the point identification section 41 sent to the section 39 and the data identifying each of the points Yp1 and Yp2 sent from the point identification section 41, the standard flight distance is calculated. A tablet terminal 76 as a terminal mounted on the golf cart 75 is provided with a predicted flight distance calculation unit 42 that calculates a predicted flight distance that is predicted to actually fly, and outputs the calculated result to, for example, the display unit 20 as data. incorporated into

In this case, in the golf hole shown in the map information 26A, the two-dimensional position of one point Yp1 where the player P hits the ball 7, and another point Yp2 when the ball reaches the standard flight distance from the one point Yp1. If the two-dimensional positions are specified by the point specifying unit 41, the altitude difference calculated by the altitude difference calculating unit 39 for the two points Yp1 and Yp2 is taken into account, and the actual flight distance is calculated based on the standard flight distance. Data indicating the calculation result of the predicted flying distance is sent from the predicted flying distance calculator 39 . Therefore, it is possible to correctly correct and predict the standard flight distance of the ball 7 hit by the player P according to the actual height difference of the golf hole.

A preferred embodiment of the present invention has been described above, but the present invention is not limited to this embodiment, and various modifications can be made without departing from the scope of the present invention. For example, part or all of the configuration of the control means 10 and the storage unit 19 in each embodiment can be transferred to devices other than the wristwatch terminal 2 and the tablet terminal 76 (for example, the mobile terminal 3, the cart management device 78, etc.). may be placed. In this case, the device and the terminal are connected to each other by wired or wireless communication means 9 . Further, as described in each embodiment, when the two-dimensional positions of one point Yp1 and another point Yp2 do not completely match the two-dimensional positions of the points of the three-dimensional mesh data, the elevation difference calculator 39 , the altitude of the point closest to one point Yp1 or another point Yp2 is obtained from the mesh information 26C, and the difference is calculated.
