A height difference notation section 105 with letters and numbers such as "-1.0 m", "AG (A green) 8.4 m", and "BG (B green) 7.9 m" is provided. However, since the cut surface 102 generally displays the cross section from the teeing ground S1 to the green S6 in one course layout diagram 101, for example, a ball hit into a rough S3 or a forest S7 is put on the course. The user could not know how the altitude was changed in the cross section when the layout was viewed in the horizontal direction in FIG. 101.

Each function of the control means 10 constitutes the height difference display system 1 of the present embodiment.

The control means 10 includes a flight distance calculation unit 27 that calculates the actual flight distance of the ball 7 hit by the player P. Explaining a specific calculation method of the flight distance with reference to FIG. 4, in the first acceleration measurement unit 11 included in the wristwatch-type terminal 2, the player P wearing the wristwatch-type terminal 2 has a specific range. When the change in acceleration corresponding to the swing of the club 6 is measured in one course, it is determined that the player P has swung the club 6, and the position information of the swing position A of the player P is acquired by the GPS receiver 12. To do. The last swing at the acquired position A is determined to be the first shot in which the player P hits the ball 7, and the position information is stored in the storage unit 19. Next, when the player P moves to the arrival point of the ball 7 hit and the first acceleration measuring unit 11 determines that the player P has swung the club 6 at that position B, the position information of the position B is received by GPS. Obtained by unit 12. The last swing at the acquired position B is determined to be the second shot in which the player P hits the ball 7, and the position information is stored in the storage unit 19. The flight distance calculation unit 27 reads the position information of the first shot and the position information of the second shot from the storage unit 19, and calculates the linear distance between the position A and the position B.

In the same manner thereafter, the position information at the shot points of the third shot, the fourth shot, and the like is acquired, the flight distances of the second shot, the third shot, and the like are calculated and stored in the storage unit 19. In the present embodiment, the last swing at the position A is determined to be the first shot in which the player P hits the ball 7, but the player P declares that he / she will shoot and then shoots. , The sound may be collected by the sound collecting unit 16 and the position information of the position A at the time of collecting the sound may be acquired by the GPS receiving unit 12, or the player P operates the operation unit 21 and the position of the position A. The information may be acquired by the GPS receiving unit 12.

Further, the flight distance calculation unit 27 calculates whether or not the ball 7 hit by the player P is deviated from the center position C of the fairway in the left-right direction. Explaining the specific calculation method for the first shot, as shown in FIG. 4, the left end position which is the intersection of the straight line perpendicular to the straight line connecting the position A and the position B and both ends of the fairway S2. The position information of L and the right end position R is read from the map information 26A. Then, the intermediate 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 S2. When the position B is separated from the center position C in the left direction by a predetermined distance (for example, 2 m) or more, it is determined that the first shot is shifted to the left, and the position B is a predetermined distance (left) in the right direction from the center position C. Similar 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. When the position B is less than a predetermined distance from the center position C, it is determined that the first shot is not displaced.

The altitude measurement unit 15 measures the altitude at the position A and sends the measured altitude information to the correction flight distance calculation unit 34 of the control means 10. The corrected flight distance calculation unit 34 calculates the height difference between the altitude of the position A and the reference altitude of 0 m above sea level, and it is assumed that the shot is taken at 0 m above sea level from the actual flight distance based on the altitude difference. The corrected flight distance is calculated. In the present embodiment, the reference altitude is set to 0 m above sea level to calculate the corrected flight distance, but this reference altitude can be set arbitrarily.

Further, the altitude measurement unit 15 also measures the altitude at the position B, and sends the measured altitude information to the correction flight distance calculation unit 34 of the control means 10. The correction flight distance calculation unit 34 compares the altitude of the position A with the altitude of the position B, and if there is a difference in altitude, calculates the height difference H. Then, when the position A is lower than the position B as shown in FIG. 5 (A), it is determined that the shot is a launch, and when the position A is higher than the position B as shown in FIG. 5 (B). Is determined to be downhill, and if there is no difference in altitude between position A and position B as shown in FIG. 5C, it is determined to be horizontal. Then, in the case of uphill or downhill, the corrected flight distance assuming that there is no height difference H between the position A and the position B is calculated from the actual flight distance based on the height difference H by a predetermined calculation formula. If it is determined to be horizontal, the actual flight distance is used as the corrected flight distance.

Next, the calculation method of the corrected flight distance calculation unit 34 in consideration of the influence of the temperature will be described with respect to the corrected flight distance of the above-mentioned first shot. The air temperature meter side unit 14 measures the air temperature at the position A, and sends the measured air temperature information to the corrected flight distance calculation unit 34 of the control means 10. The corrected flight distance calculation unit 34 calculated the temperature difference between the air temperature at position A and the reference temperature of 20 degrees Celsius, and based on the temperature difference, shot at 20 degrees Celsius from the actual flight distance using a predetermined formula. Calculate the corrected flight distance when assuming. In the present embodiment, the reference temperature is set to 20 degrees Celsius to calculate the corrected flight distance, but this reference temperature can be set arbitrarily.

Next, the calculation method of the corrected flight distance calculation unit 34 in consideration of the influence of atmospheric pressure will be described with respect to the corrected flight distance of the above-mentioned first shot. The barometer side unit 15 measures the atmospheric pressure at the position A and sends the measured atmospheric pressure information to the corrected flight distance calculation unit 34 of the control means 10. The corrected flight distance calculation unit 34 calculates the atmospheric pressure difference between the atmospheric pressure at position A and the reference temperature of 1013 hectopascals, and it is assumed that the shot is taken at 1013 hectopascals from the actual flight distance based on the atmospheric pressure difference by a predetermined formula. Calculate the corrected flight distance for the case. In the present embodiment, the reference pressure is set to 1013 hectopascals to calculate the corrected flight distance, but this reference pressure can be set arbitrarily.

The condition of the ground S is tee ground S1, fairway S2, rough S3, bunker S4, pond S5, green S6, uphill and downhill, and the wind strength at the time of shot is "strong" and "weak". Yes, the wind directions are "against", "follow" and "crosswind". The corrected flight distance may be calculated in consideration of other environmental conditions that affect the flight distance of the ball 7.

As shown in FIG. 3, the control means 10 includes a term determination unit 35 for determining voice information transmitted from the sound collection unit 16. Further, the control means 10 includes a term dictionary unit 36 for storing pre-registered terms. The terms registered in advance are, for example, "tee ground", "fairway", "rough", "bunker", "pond", "uphill slope", "downhill slope", "against", "follow", "follow". It represents the state of the shot point such as "crosswind". Upon receiving the voice information from the sound collecting unit 16, the term determination unit 35 determines whether or not the term related to the voice information is a term stored in the term dictionary unit 36. When the term is stored in the term dictionary unit 36, the term determination unit 35 sends a term signal corresponding to the term to the correction flight distance calculation unit 34. When the corrected flight distance calculation unit 34 receives the term signal, it is assumed that the shot point is the fairway S2 from the actual flight distance, there is no inclination, and there is no wind, according to a predetermined calculation formula corresponding to the term. Calculate the corrected flight distance. In the present embodiment, the reference state of the shot point is set to the fairway S2, there is no inclination, and there is no wind, and the corrected flight distance is calculated. However, this reference state can be set arbitrarily.

The term dictionary unit 36 stores the term corresponding to the number of the club 6 in advance, and by inputting the number of the club 6 by voice before taking a shot, the term (the number of the club 6) corresponds to the term. The count information of the club 6 is transmitted from the term determination unit 35 to the correction flight distance calculation unit 34. Therefore, the flight distance calculation unit 27 sends the flight distance information in which the actual flight distance corresponds to the number of the club 6 to the storage unit 19. Similarly, the corrected flight distance calculation unit 34 also sends the corrected flight distance information in which the calculated corrected flight distance corresponds to the number of the club 6 to the storage unit 19. Each time the storage unit 19 receives such flight distance information and corrected flight distance information, the storage unit 19 stores and stores them as flight distance history information 26B, which is a history of the actual flight distance and the corrected flight distance according to the number of the club 6. The terms stored in the term dictionary unit 36 can be updated such as addition, deletion, and change.

In the present embodiment, the method of inputting the state of the shot point and the number of the club 6 by voice is adopted, but the state of the shot point and the number of the club 6 may be input by operating the operation unit 21. Also in this case, the history of the actual flight distance and the corrected flight distance played by the player P in the past is stored and stored in the storage unit 19 as the corrected flight distance history information 26B.

Further, in the present embodiment, the atmospheric pressure, the air temperature, and the altitude are all measured and the state of the shot point is input. However, for example, the items to be measured and the items to be input can be arbitrarily determined, such as not measuring the air temperature. Yes, you may add items other than these.

The second acceleration measuring unit 53 measures the acceleration, speed, and inclination of the waist Pk of the player P by swinging the player P while the mobile terminal 3 is housed in the right rear pocket 8A. The acceleration information, velocity information, and inclination information measured by the second acceleration measurement unit 53 are transmitted to the analysis unit 62 of the control means 52.

The GPS receiving unit 54 constitutes a position measuring means for acquiring the current position of the mobile terminal 3, and wirelessly receives radio waves from a plurality of artificial satellites 28 to obtain a three-dimensional position (longitude, latitude and The altitude) is measured and the position information is sent to the control means 52. If the current position of the mobile terminal 3 can be detected, a position detecting device other than the GPS receiving unit 54 may be used. In addition, an atomic clock is mounted on the artificial satellite 28. An extremely accurate time signal wave is transmitted from the artificial satellite 28 at a specific frequency, and the time axis of the mobile terminal 3 is defined by receiving this by the GPS receiving unit 54. As described above, since the wristwatch-type terminal 2 also receives the time signal wave from the artificial satellite 28 and defines the time axis, the time axes of the wristwatch-type terminal 2 and the mobile terminal 3 are synchronized.

The transmission / reception unit 55 enables bidirectional communication between the wristwatch-type terminal 2 and the mobile terminal 3 via the wireless communication means 9.

In the mobile terminal 3 of the present embodiment, the transparent touch panel 57A provided on the surface of the display unit 57 functions as the operation unit 58. Buttons and keys for other operations may be used as the operation unit 58.

The analysis unit 62 calculated the acceleration of the left wrist Pw of the player P measured by the first acceleration measurement unit 11, the acceleration of the waist Pk of the player P measured by the second acceleration measurement unit 53, and the flight distance calculation unit 27. Based on the flight distance of the ball 7, the relationship between the movements of the left wrist Pw and the waist Pk of the player P and the flight distance is analyzed. In the present embodiment, the relationship between the so-called tame, the acceleration, velocity and inclination of the left wrist Pw, the acceleration, velocity and inclination of the waist Pk, and the flight distance of the ball 7 in the swing of the player P is analyzed.

As described above, the time axes of the first acceleration measurement unit 11 of the wristwatch type terminal 2 and the second accelerometer side unit 53 of the mobile terminal 3 are synchronized, and when the player P swings, the first acceleration measurement unit 11 Measures the 3-axis combined acceleration of the left wrist Pw of the player P, and measures the 3-axis combined acceleration of the waist Pk of the player P on the side 53 of the second accelerometer. Further, as described above, the flight distance measuring unit 27 of the wristwatch-type terminal 2 stores the actual flight distance of the ball 7 in the storage unit 19 corresponding to the number of the club 6. The 3-axis synthetic acceleration information of the left wrist Pw of the player P and the flight distance information corresponding to the count of the club 6 are transmitted to the analysis unit 62 via the transmission / reception unit 18 of the wristwatch type terminal 2 and the transmission / reception unit 55 of the mobile terminal 3. At the same time, the three-axis synthetic acceleration information of the waist Pk of the player P is transmitted to the analysis unit 62. These pieces of information are associated and stored in the storage unit 56.

Here, the calculation of the charge in the swing of the player P will be described. FIG. 8 shows a polygonal line G1 showing the time course of the triaxial synthetic acceleration of the left wrist Pw and a polygonal line G2 showing the time course of the triaxial synthetic acceleration of the waist Pk.

In the present embodiment, it is assumed that the swing in which the peak GP2 of the 3-axis combined acceleration of the waist Pk occurs earlier in time than the peak GP1 of the 3-axis combined acceleration of the left wrist Pw has a problem. Then, when the peak GP1 occurs earlier than the peak GP2 in time, or when the time difference t between the peak GP1 and the peak GP2 is 0, it is assumed that there is no damage. Further, the time difference t when there is a time difference t among the time difference t is referred to as a time difference T. Note that FIG. 8 shows the three-axis combined acceleration of the left wrist Pw and the waist Pk of the swing when there is a tame.

The velocity of the left wrist Pw of P is calculated by a predetermined formula. For the speed of the left wrist Pw, the average speed of the swing from the top P3 to the impact P4, the speed in a unit time at the moment of the impact P4, and the like are calculated. For example, the instantaneous velocity V = 5.75 m / s at the impact P4 in this embodiment.

Further, the speed calculation unit 65 calculates the speed of the waist Pk of the player P by a predetermined calculation formula based on the three-axis combined acceleration information of the waist Pk of the player P. For the speed of the waist Pk, the average speed in the swing, the speed in the 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 a tilt calculation unit 66, and the tilt calculation unit 66 bases the wristwatch-type terminal 2 and eventually the wristwatch-type terminal 2 based on the three-axis synthetic acceleration information of the left wrist Pw of the player P. The inclination of the left wrist Pw of the player P is calculated by an angle in the three axial directions. The inclination of the left wrist Pw is calculated at each point of the rest state P1 of the address, the middle of the backswing (the left wrist Pw starts to become lighter) P2, the top P3, the impact P4, the follow P5, and the finish P6. For example, the inclination of the left wrist Pw in the stationary state P1 of the address in the present embodiment is θx = 5.5, θy = 42.5, and θz = -21.1.

Further, the inclination calculation unit 66 calculates the inclination of the waist Pk of the player P at an angle in the three-axis direction based on the three-axis combined acceleration information of the waist Pk of the player P. The inclination of the waist Pk is calculated at each point of the stationary state P1 of the address, the middle of the backswing (the left wrist Pw starts to become lighter) P2, the top P3, the impact P4, the follow P5, and the finish P6.

By continuing to measure various information in the swing of the player P in this way, the measurement results are accumulated in the storage unit 56. From the accumulated measurement results, the analysis unit 62 calculates the time T of the swing time when the flight distance is the longest, the acceleration, speed and inclination of the left wrist Pw and the waist Pk, and sets these conditions for the player P. It is stored in the storage unit 56 as the best swing. The time T of the tame in this best swing, the acceleration, speed and inclination of the left wrist Pw and the waist Pk can be displayed on the display unit 57 of the mobile terminal 3, and the player P can confirm these information. In addition, the average value of the time T of the swing of the predetermined number of times (for example, 10 times) that the flight distance was long, the acceleration, speed, and inclination of the left wrist Pw and the waist Pk is calculated, and the result is displayed on the display unit 57. You can also do it. If the information is stored in the storage unit 56, various information on the swing having a short flight distance can be displayed on the display unit 57.

The program 23 stored in the storage unit 19 and the program 59 stored in the storage unit 56 also correspond to an advice information presentation program. The advice information presentation system 67 is realized by executing the programs 23 and 59 by the wristwatch-type terminal 2 and the mobile terminal 3 which are computers. The height difference display system 1 also includes the functions of the advice information presentation system 67.

As shown in FIG. 3, the control means 10 of the wristwatch type terminal 2 includes an advice calculation unit 37. The advice calculation unit 37 calculates advice information when presenting advice such as advice / advice to the player P. The advice can be notified by voice from the notification unit 22 included in the wristwatch-type terminal 2, or can be displayed on the display unit 20 of the wristwatch-type terminal 2 by characters, figures, a map, or the like. The advice information can be selected by operating the operation unit 21 whether to display the advice information on the display unit 20, to notify by voice by the notification unit 22, or to use both.

Specific advice information will be described below. When the player P inputs the course information of the golf course by voice or the operation of the operation unit 21, the advice calculation unit 37 reads and displays the data of the layout diagram 26A1 included in the map information 26A of the corresponding course from the storage unit 19. Displayed in unit 20. In the display of the layout diagram 26A1, the position information of the player P wearing the wristwatch type terminal 2 is measured, and the player P enters the course from the position information of the course stored in advance in the storage unit 19. When this is confirmed, the data of the corresponding layout diagram 26A1 may be read from the storage unit 19 and automatically displayed on the display unit 20 by the display control unit 40.

Hazard information is position information of bunker S4, pond S5, etc., distance information from the current position to the bunker S4, pond S5, etc., and words such as "Caution for left bunker!" Are displayed on the display unit 20. Or, the notification unit 22 notifies by voice. The layout diagram 26A1 in the course screen 47 displayed on the display unit 20 by the display control unit 40 is displayed in color, and the tee ground S1, fairway S2, rough S3, bunker S4, pond S5, and green S6 are in different colors. Since it is displayed as, the hazard information is easy to check visually.

When the player P inputs a shot to the watch-type terminal 2 by voice or operation of the operation unit 21, the advice calculation unit 37 receives the latest position information of the player P acquired from the GPS receiving unit 12 at that time and the latest position information thereof. From the map information 26A of the course corresponding to the position information, the position where the shot of the player P, which is one point, is scheduled to be performed, and the distance to the fairway S2 and the green S6 are calculated. Further, the flight distance history information 26B is read from the storage unit 19, and the average flight distance and the average corrected flight distance in each count of the player P are calculated based on the flight distance and the corrected flight distance history for each count obtained from the information. , The recommended club 6 count suitable for the distance to the fairway S2 and the green S6 is presented. At this time, the advice calculation unit 37 cooperates with the display control unit 40 on the same course screen 47 as the layout diagram 26A1 of the course where the player P is located, and the recommended club 6 count is set to the count notation unit 68. The past average flight distance of the corresponding player P is displayed on the display unit 20 by the flight distance history notation unit 69 (see FIG. 2).

Further, on the course screen 47, a notation unit 70 for returning with a symbol and a notation unit 71 for advancing are arranged on the left and right of the count notation unit 68, respectively. By tapping the surface of the back notation unit 70 and the forward notation unit 71, the advice calculation unit 37 cooperates with the display control unit 40 to perform the average flight distance of the club 6 other than the recommended club 6 in the count of the club 6. Can be displayed on the display unit 20 by the flight distance history notation unit 69 on the course screen 47. At this time, the count of the selected club 6 is displayed on the count notation unit 68.

Further, the advice calculation unit 37 also calculates the rate and tendency of the player P's shot to be displaced in the left-right direction when the recommended club 6 is used. The advice calculation unit 37 reads out the ratio of the player P's shot in the left-right direction from the storage unit 19, and presents it on the display unit 20 or the notification unit 22. As a method of presenting the deviation in the left-right direction, the deviation ratio may be displayed on the display unit 20 or may be notified by voice by the notification unit 22, and the tendency of the shot of the player P is calculated from the deviation ratio. , The tendency may be displayed on the display unit 20 with a phrase such as "65% deviation to the left, caution!", Or may be notified by voice by the notification unit 22.

In addition, the advice calculation unit 37 includes the average length of the time T of the shot in which the player P has a long flight distance in the past and the shot in which there is no deviation in the left-right direction, the acceleration, velocity and inclination of the left wrist Pw. , The acceleration, speed and inclination of the waist Pk can be calculated and the result can be displayed on the display unit 20 or notified by the notification unit 22.

Further, if the height difference H is known in advance whether the next shot by the player P will be a launch or a downhill, that fact will be notified 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 launching and downhill of the player P is calculated from the corrected flight distance history information 26B. , 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, upslope, downslope, wind strength, wind direction, etc.) can be controlled by voice or by operating 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, and the past average flight distance corresponding to the state of the player P is calculated from the corrected flight distance history information 26B and displayed on the display unit 20. You can also do it.

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 flight distance information of the past shots included in the corrected flight 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 the failed shot in which the actual flight distance is extremely short, and the result may be presented to 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, displays advice according to the heart rate on the display unit 20, or notifies the notification unit 22. can do. For example, when the advice calculation unit 37 takes in the acceleration information from the first accelerometer side unit 11 and the position information from the GPS receiving unit 12, and determines that the player P has shot at a specific position (for example, in the bunker). In addition, based on the pulse wave information from the heart rate measurement unit 17, if the heart rate of the player P rises above the predetermined value before and after the shot, it says, "You did your best (escape from the bunker)." The notification unit 22 notifies the message of encouragement. This makes it possible to raise the motivation of player P and continue playing happily.

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

In FIG. 3, the control means 10 has a function as a height difference grasping unit 40 for grasping the height difference of arbitrary two points with respect to the two-dimensional map information 26A stored in the storage unit 19. The elevation difference grasping unit 40 accesses a server (not shown) connected to the network 63 in cooperation with the mobile terminal 3, and maps information from the basic map information of the National Land Research Institute stored and stored in the server. Regarding the entire golf course included in the target range of 26A, in particular, the altitude data of the 5 m mesh is acquired from the transmission / reception unit 55 of the mobile terminal 3 via the communication means 9, and the altitude data is used as the map information 26A of the golf course. The mesh data acquisition unit 38, which is embedded and independently generates three-dimensional mesh data of latitude, longitude, and altitude, and the altitude of one point where the latitude and longitude are specified in the golf course included in the map information 26A. And the altitude difference calculation unit 39 that calculates the difference from the altitude of another point by using the three-dimensional mesh data generated by the mesh data acquisition unit 38. When the mesh data acquisition unit 38 generates the above-mentioned three-dimensional mesh data, it is preferable to store it in the storage unit 19 as mesh information 26C. As a result, the altitude difference calculation unit 39 can read the mesh information 26C stored in the storage unit 19 and calculate the altitude difference between one point and the other point, and the altitude difference calculation unit 39 can calculate the altitude difference. Every time the difference is calculated, the time and effort required for the mesh data acquisition unit 38 to generate the three-dimensional mesh data can be omitted.

Further, the control means 10 has functions as a point identification unit 41 and a predicted flight distance calculation unit 42 in addition to the height difference grasping unit 40. The point identification unit 41 acquires the position information from the GPS receiving unit 12, identifies the two-dimensional position of one point where the player P will make a shot from now on, and then the club 6 recommended by the player P from the one point. When the standard flight distance data, which is the average flight distance when the ball 7 is hit with the number of, is acquired from the flight distance history information 26B of the storage unit 19, and the ball 7 reaches the standard flight distance from one point. After specifying the two-dimensional positions of other points, the data of the two-dimensional positions of these two points is sent to the altitude difference calculation unit 39. Upon receiving this data, the elevation difference calculation unit 39 starts calculating the elevation difference between the above-mentioned one point and the other point.

The predicted flight distance calculation unit 42 predicts that the data that identifies the two points sent from the point identification unit 41 actually flies with respect to the standard flight distance based on the altitude difference calculated by the altitude difference calculation unit 39. The flight distance to be calculated (predicted flight distance) is calculated, and the calculation result is output as data. The output destination of this data is the display unit 20. Here, the lower the altitude of the other point than the altitude of one point, the longer the shot from one point is predicted to be downhill, so the predicted flight distance is calculated to be longer than the standard flight distance. Conversely, the higher the altitude of another point than the altitude of one point, the shorter the shot from one point is predicted at launch, so the predicted flight distance is calculated to be shorter than the standard flight distance.

FIG. 9 shows an aerial photograph of the entire golf course and an example of elevation data superimposed on the aerial photograph. In the figure, reference numeral X is a golf course taken by an aerial photograph, and a layout diagram 26A1 of map information 26A designed as shown in FIGS. 2 and 4 is provided in advance based on the aerial photograph X of the golf course. Created for each course. Further, the symbol Y indicates an area in which the elevation data of the 5 m mesh can be acquired in the basic map information issued by the Geospatial Information Authority of Japan. The elevation data of the 5 m mesh can be acquired by the mesh data acquisition unit 38 of the height difference grasping unit 40 accessing the server connected to the network 63. In addition to the 5 m mesh, the elevation data of the 10 m mesh is also prepared for the base map information, but it is preferable to use the elevation data of the 5 m mesh with fine data.

The mesh data acquisition unit 38 acquires the altitude data of the entire inside of the thick frame including the entire golf course X from the server connected to the network 63 described above via the mobile terminal 3. Here, the altitude of the 5m mesh is 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 the acquired altitude data is used to create three-dimensional mesh data consisting of latitude, longitude, and altitude at 5 m intervals corresponding to each course of map information 26A. The three-dimensional mesh data created by the mesh data acquisition unit 38 is stored and held in the storage unit 19 as the mesh information 26C in association with the map information 26A of each course.

FIG. 10 is an enlarged view of the entire specific course Xh in the golf course X shown in FIG. In the figure, the reference numeral YL indicates a line of a 5 m mesh.
The mesh data acquisition unit 38 acquires elevation data of a 5 m mesh for each course Xh of the golf course X, and obtains three-dimensional map information 26A including the elevation for the two-dimensional map information 26A designed for each course Xh. 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 5 m intervals for the entire course Xh.

FIG. 11 shows the elevation of each point Yp included in the mesh information 26C at a specific location in the course 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 together with the altitude. By reading the mesh information 26c from the storage unit 19, the altitude difference calculation unit 39 can calculate the altitude difference between any two points Yp1 and Yp2 from the mesh information 26c at any point Yp in the course Xh. For example, the elevation 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 another point Yp2 "18.53" meters, that is, 18.53- It can be calculated as 16.71 = 1.82 meters. Further, since the mesh information 26c also includes latitude and longitude information, the elevation difference calculation unit 39 calculates in which direction and what elevation difference the ground S is tilted from one point Yp1. You can also grasp it.

The calculation of the altitude difference (height difference) by the height difference grasping unit 40 is the altitude with another point Yp2 specified from the standard flight distance of the player P when the player P hits the ball 7 from one point Yp1. It can be used to calculate the predicted flight distance taking into account the difference.

FIG. 12 shows an example of the height difference expression using the altitude data displayed on the display unit 20 in the height difference display system 1 of the present embodiment. As described above, when the player P inputs a shot to the wristwatch type terminal 2 by voice or operation of the operation unit 21, the advice calculation unit 37 takes in the position information of the player P from the GPS receiving unit 12 and the position information. By superimposing the map information 26A of the course including the above, the past average flight distance of the player P corresponding to the recommended club 6 count is displayed on the arc line (radar) 73 centered on the position of the player P. To display. As described above, the recommended club 6 count is automatically set by the advice calculation unit 37 according to the relationship between the position of the player P and the positions of the fairways S2 and the green S6 included in the map information 26A.

At this time, the point identification unit 41 identifies the position information from the GPS receiving unit 12 captured by the advice calculation unit 37 as a two-dimensional position of one point Yp1 where the player P next makes a shot, and also the advice calculation unit 37. Based on the average flight distance calculated in step 1, when the ball 7 is hit with the average flight distance from one point Yp1, the point that reaches the center position C of the fairway S2 and green S6 is specified as another point Yp2, and each location. The two-dimensional positions of the points Yp1 and Yp2 are sent to the elevation difference calculation unit 39. The point identification unit 41 may include the function of the advice calculation unit 37.

When the point identification unit 41 identifies the two-dimensional positions of one point Yp1 and the other point Yp2, the altitude difference calculation unit 39 calculates the altitude difference between the two points Yp1 and Yp2 and sends it to the predicted flight distance calculation unit 42. To do. In response to this, the predicted flight distance calculation unit 42 actually adds the height difference acquired from the altitude difference calculation unit 39 to the average flight distance displayed as the arc line 73 on the display unit 20, and the ball 7 actually moves. The flight distance predicted to fly is calculated, and the calculation result is displayed as a percentage 74 near the center position C of the fairway S2 where the arc lines 73 intersect. As a result, it is 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 on the actual course, and display this on the display unit 20 at a percentage of 74, for example. As a result, the player P can correctly predict the flight distance of the ball 7.

In the example shown in FIG. 12, when the player P inputs a shot to the watch-type terminal 2 on the tee ground S1 of the course displayed on the display unit 20, the point identification unit 41 becomes one on the tee ground S1. Identify the latitude and longitude of point Yp1, and identify the latitude and longitude of another point Yp2 that reaches the center position C of fairway S2 when player P hits the ball 7 with an average flight distance from one point Yp1. Then, these data are sent to the altitude difference calculation unit 39. The altitude difference calculation unit 39 acquires 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 also obtains altitude data 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, suppose that the average flight distance in the past when player P hits the ball 7 with the recommended number club 6 from one point Yp1 is 215 yards. At this time, assuming that the altitude of the point closest to one point Yp1 is 240 meters and the altitude of the point closest to the other points Yp2 is 270 meters, the elevation difference calculation unit 39 targets the target when viewed from one point Yp1. The elevation difference from the other point Yp2 is calculated to be a launch of 30 meters (-30 m). In response to this calculation result, the predicted flight distance calculation unit 42 causes the display unit 20 to display at a percentage of 74 that the predicted flight distance is 95% of the average flight distance of 215 yards.

The calculation result of the predicted flight distance 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 notify an announcement such as "It is predicted that the flight distance will be 95% of the average flight distance". In addition, the predicted flight distance itself (for example, "204 yards" corresponding to 215 x 95%) may be directly displayed or notified instead of the percentage.

Next, the configuration and operation of each unit when the control means 10 reads the height difference display program flight distance prediction program as a program from the storage unit 19 will be described. A part of the height difference display program also serves as a flight distance prediction program.

In FIG. 3, the control means 10 includes a point setting unit 43, an altitude acquisition unit 44, and a display control unit 45. The point setting unit 43 sets one point and another point in each course of the golf course to be the target range. The one point referred to here may be the same as one point based on the position information from the GPS receiving unit 12 specified by the point identification unit 41, or may be another point. For example, in a state where the display control unit 45 displays the layout diagram 26A1 as shown in FIG. 12 on the display unit 20, the player P who is the user touches the touch panel 32B to touch the touched layout diagram 26A1. The point may be changed by the point setting unit 43 as one point.

In addition, the point setting unit 43 is configured so that the settings of other points can be changed arbitrarily. Specifically, in a state where the display control unit 45 displays the layout diagram 26A1 on the display unit 20, the player P who is the user touches the touch panel 32B to obtain a point on the touched layout diagram 26A1. The point setting unit 43 may change the setting as another point. In this case, each time the touch panel 32B is touch-operated, other points can be arbitrarily set and changed. Further, if the terminal owned by the user such as the wristwatch type terminal 2 or the mobile terminal 3 is equipped with an orientation sensor (geomagnetic sensor) that detects the direction in which the terminal is facing, the detection output from the orientation sensor is output. The point setting unit 43 receives and changes the setting of an arbitrary point in the direction in which the terminal is facing from one point that is the current position of the terminal based on the position information from the GPS receiving units 12 and 54 to another point. By configuring the point setting unit 43, it is possible to automatically change the setting of another point in the direction in which the terminal is directed without inputting an operation to the operation unit 21.

The altitude acquisition unit 44 is a three-dimensional mesh in which the altitude of each point is stored in the mesh information 26C for each point on the first line connecting one point and another point set by the point setting unit 43. It is obtained from the data. In response to this, the display control unit 45 controls the display unit 20 so that the first line is displayed on the layout diagram 26A1. Further, when one of the points is set as a specific point on the first line described above, the altitude acquisition unit 44 is a second line that passes through the specific point orthogonal to the first line. Is set, and for each point on the second line, the elevation of each point is acquired from the three-dimensional mesh data. In response to this, the display control unit 45 controls the display unit 20 so that the second line is displayed on the layout diagram 26A1. The first line and the second line are straight lines or curved lines.

The display control unit 45, as a function related to the height difference display program in particular, maps information on changes in altitude from one point to another based on the altitude of each point on the first line acquired by the altitude acquisition unit 44. Together with the layout diagram 26A1 included in 26, it has a configuration in which the display unit 20 of the wristwatch-type terminal 2 is displayed as a first elevation line. In this case, the first elevation line is the elevation of one point as a reference, and the change in elevation from one point to another is changed from the first line to an uneven shape. It is preferable to represent it. Further, the display control unit 45 transmits the change in altitude along the second line to the display unit 20 of the wristwatch type terminal 2 based on the altitude of each point on the second line acquired by the altitude acquisition unit 44. It has a structure to be displayed by the line of.

FIG. 13 shows a basic example of the course screen 47 displayed on the display unit 20 of the wristwatch-type terminal 2 in the height difference display system 1 of the present embodiment. In the figure, the display control unit 45 watches the course screen 47 on which the layout diagram 26A1 of the flat course in the golf course and the cutting diagram 75 showing one typical cross section in the layout diagram 26A1 are arranged. It is displayed on the display unit 20 of the type terminal 2. Here, when the position information of the player P is fetched from the GPS receiving unit 12, the map information 26A including the position information is read out, so that the layout diagram 26A1 of the course where the player P is located is displayed on the course screen 47. Can be made to. In layout diagram 26A1, tee ground S1, fairway S2, rough S3, bunker S4, pond S5, green S6, and forest S7, which are the main objects in the course, are arranged. Further, the above-mentioned percentage 74 may be displayed on the course screen 47.

In the layout diagram 26A1 of the course displayed on the display unit 20, the display control unit 45 of the present embodiment sets one point and the other points set by the point setting unit 43 as the first point Sp1. It is displayed as a symbol as the second point Sp2. When the touch panel 32B is touch-operated on the surface of the point Sp1 displayed on the display unit 20 and the finger is moved in the same state, the moved fingertip is changed as one point by the point setting unit 43, and the point is set at that position. The display of Sp1 also moves. Similarly, when the touch panel 32B is touch-operated on the surface of the point Sp2 displayed on the display unit 20 and the finger is moved in that state, the moved fingertip is set as one point by the point setting unit 43, and the setting is changed. The display of the point Sp2 also moves to the position.

In this way, when the point setting unit 43 sets one point and another point, the altitude acquisition unit 44 sets the altitude of each point for each point on the first straight line connecting the one point and the other point. It is acquired from the three-dimensional mesh data stored and stored in the mesh information 26C. At this time, the display control unit 45 causes the display unit 20 to display the first straight line L1 connecting the points Sp1 and Sp2 on the layout diagram 26A1, and causes the player P, who is a user, to view a cross section of which cross section on the layout diagram 26A1. It is possible to intuitively recognize whether it is displayed as 75.

On one side of the course screen 47, a cut diagram 75 in the first straight line L1 on the layout diagram 26A1 is arranged, and the cut diagram 75 is from the first point Sp1 which is a point set by the player P. , In order for the player P to visually recognize the change in altitude up to the second point Sp2, which is another point, the altitude of each point on the first straight line acquired by the altitude acquisition unit 44 is shown as a line graph. A first elevation line H1 connected to is provided. Further, in the cut diagram 75, if necessary, the elevation difference, which is the difference in elevation from the point Sp1 serving as the reference point, is indicated by letters and numbers such as "-3.0 m". Is provided. The display control unit 45 displays the cut section 75 together with the layout diagram 26A1 on the display unit 20 on the common course screen 47, so that the player P can operate the positions of the points Sp1 and Sp2 on the touch panel 32B as necessary. Just by changing the setting by input, how the altitude is not only for the cross section from the teeing ground S1 to the green S6 in the layout diagram 26A1 but also for the cross section that you want to know, for example, in the direction of hitting the ball 7. Whether it is changing or not can be immediately visually recognized by the display of the first altitude line H1 provided in the cut section 75.

FIG. 14 shows another preferable example of the course screen 47 displayed on the display unit 20 of the wristwatch-type terminal 2 in the height difference display system 1 of the present embodiment. In addition to the count notation unit 68, the flight distance history notation unit 69, the return notation unit 70, and the forward notation unit 71 described above, the course screen 47 is provided with an altitude difference notation unit 81 and a predicted distance notation unit 82. The support information display window 83 is arranged below the support information display window 83. The support information display window 83 can be displayed or hidden on the course screen 47 at any time by a specific operation of the operation unit 21, for example, on the touch panel 32B. In the area other than the support information display window 83 of the course screen 47, the layout diagram 26A1 described above, the second point Sp2, the first straight line L1, and the first cutting diagram 75 including the first elevation line H1 are included. In addition, the slide line SD, the arc line 85 of the predicted flight distance, the second straight line L2, the second cut diagram 86 including the second elevation line H2, and the markers MA1, MB1, MA2, MB2 , Each placed. The display control unit 45 controls the display unit 20 so that the course screen 47 is displayed.

Then, when the position information of the player P is taken in from the GPS receiving unit 12, the map information 26A including the position information is read out, so that the support information display window 83 is displayed together with the layout diagram 26A1 of the course where the player P is located. The included course screen 47 is displayed on the display unit 20. The support information display window 83 displays the number of the club 6 recommended first, and after tapping the surface of the back notation section 70 or the forward notation section 71, the number notation section for displaying the number of the selected club 6 is displayed. About 68 and the count of club 6 displayed in the count notation unit 68, the altitude difference calculated by the altitude difference calculation unit 39 and the flight distance history notation unit 69 which displays the average flight distance calculated by the advice calculation unit 37. The altitude difference notation unit 81 for displaying the above and the predicted flight distance notation unit 82 for displaying the predicted flight distance calculated by the predicted flight distance calculation unit 42 are arranged respectively.

On the other hand, in the area other than the support information display window 83 of the course screen 47, the second symbol of the diamond symbol, which is another point set by the point setting unit 43, is superimposed on the layout diagram 26A1 of the course where the player P is located. Point Sp2, the first straight line L1 connecting one point and another point set by the point setting unit 43, and the altitude of one point based on the first straight line L1, from one point to the other The first cut diagram 75 including the first elevation line H1 which displays the change in altitude up to the point of the first line by changing it in an uneven shape from both sides of the first line, and on the first straight line L1 of each point. When one of the points is set as the specific point T, the second straight line L2 and the second straight line L2 that pass through the specific point T1 and are displayed so as to be orthogonal to the first straight line L1 are displayed. A second cut diagram 86 including the first elevation line H2, which displays the change in elevation along the second line as the elevation of the reference specific point T by changing it from the second line in an uneven shape, is shown in FIG. , Each placed. In FIG. 14, the first point Sp1 is hidden and not displayed by the support information display window 83, but the first point Sp1 is from the GPS receiving unit 12 taken in by the advice calculation unit 37 by the point identification unit 41. The position information corresponds to the above-mentioned one point Yp1 specified as the two-dimensional position of the one point Yp1 where the player P next makes a shot. Therefore, the first point Sp1 is the current position of the wristwatch-type terminal 2 and the player P itself, which is positioned by the GPS receiving unit 12.

On the other hand, at the second point Sp2 arranged on the upper side of the course screen 47, when the touch panel 32B is touch-operated on the surface and the finger is moved left and right along the slide line SD in the same state, the moved fingertip is moved. The setting is changed by the point setting unit 43 as another point, and the display of the second point Sp2 also moves to that position. That is, in this example, from the position of the player P himself, which is the first point, to which direction of the course shown in the layout diagram 26A1 the change in the elevation difference is to be displayed on the first elevation line H1. , The second point Sp2 can be easily selected by simply sliding it with a finger along the slide line SD.

Each time the point setting unit 43 changes the position of another point, the altitude acquisition unit 44 sets the altitude of each point on the first straight line L1 connecting one point and another point. Acquired from the three-dimensional mesh data stored and saved in the mesh information 26C, the display control unit 45 causes the display unit 20 to display the first straight line L1 connecting the points Sp1 and Sp2 on the layout diagram 26A1. As a result, the player P, who is the user, can intuitively recognize which cross section is displayed as the cross-sectional view 75 on the layout diagram 26A1.

The first cut FIG. 75 in this example shows the first straight line L1 in the first color (for example, red: dark color in FIG. 14) for each point on the first straight line L1 acquired from the three-dimensional mesh data. The portion of the convex first elevation line H1 appearing on one side indicates that the elevation is higher than the reference one point, and the second color (for example, blue: light color in FIG. 14) is the first. It is shown that the portion of the concave first elevation line H1 appearing on the other side of the straight line L1 is lower than one reference point. Since both the first straight line L1 and the first cut diagram 75 are displayed superimposed on the layout diagram 26A1, the player P shows in the layout diagram 26A1 in the direction of the first straight line L1 desired by the player P. It is possible to intuitively recognize which area has what kind of altitude difference by the first altitude line H1 shown in a concave-convex shape.

Apart from the above-mentioned specific point T, the altitude acquisition unit 44 provides two-dimensional map information including a layout diagram 26A1 to be displayed on the display unit 20 for each point on the first straight line L1 acquired from the three-dimensional mesh data. Based on, for example, a point located at the center of the fairway S2 or located at the point bunker S4 is set as a point of interest for the player P. In response to this, the display control unit 45 displays each point of interest on the first straight line L1 with the markers MA1 and MB1 by symbols. As a result, the player P recognizes that the elevation is lower than the current position because the concave first elevation line H1 appears on the other side of the marker MA1 at the center position of the fairway S2 on the first straight line L1. Also, at the position of the bunker S4 on the first straight line L1, since the convex first altitude line H1 appears on one side of the marker MB1, it can be recognized that the altitude is higher than the current position, and the player can recognize it. It is possible to make P intuitively recognize the altitude of the point of interest.

The altitude acquisition unit 44 is 10 yards from the predicted flight distance (230 yards in FIG. 14) calculated by the predicted flight distance calculation unit 42 among the points on the first straight line L1 acquired from the three-dimensional mesh data. A point in front (220 yards in FIG. 14) is set as a specific point T. However, this is just an example, and the average flight distance calculated by the advice calculation unit 37 or the predicted flight distance calculated by the predicted flight distance calculation unit 42 is reached from one point on the first straight line L1. The point may be set as a specific point T without adding or subtracting by a preset distance, or may be arbitrarily changed by inputting an operation to the operation unit 21. In any case, when the altitude acquisition unit 44 sets the specific point T and the second straight line L2 and acquires the altitude of each point on the second straight line L2 from the three-dimensional mesh data, the display control unit On the course screen 47, the second cut-out drawing 86 including the second elevation line H2 together with the second straight line L2 can be superimposed on the layout drawing 26A1 and displayed on the display unit 20.

The second cut FIG. 86 in this example shows the second straight line L2 in the first color (for example, red: dark color in FIG. 14) for each point on the second straight line L2 acquired from the three-dimensional mesh data. The convex second elevation line H2 appearing on one side indicates that the elevation is higher than the reference one point, and the second color (for example, blue: light color in FIG. 14) is used. It is shown that the portion of the concave second elevation line H2 appearing on the other side of the straight line L2 is at an altitude lower than one reference point. Since both the second straight line L2 and the second cut diagram 86 are displayed superimposed on the layout diagram 26A1, the player P is laid out in the direction of the second straight line L2 orthogonal to the first straight line L1. It is possible to intuitively recognize which area shown in FIG. 26A1 has what kind of elevation difference by the second elevation line H2 shown in an uneven shape.

The altitude acquisition unit 44 includes a layout diagram 26A1 for displaying points located at a distance determined from a specific point T or on the display unit 20 for each point on the second straight line L1 acquired from the three-dimensional mesh data. However, based on the two-dimensional map information, for example, a point located at the boundary between the fairway S2 and the rough S3 and a point of interest for the player P are set. In response to this, the display control unit 45 displays each point of interest on the first straight line L2 with the markers MA2 and MB2 by symbols. As a result, when the player P hits the ball 7 on the left side of the fairway S2 near the predicted flight distance, the concave second elevation line H2 appears on the other side of the marker MA2, so that the ball It can be recognized that 7 falls from the fairway S2 to the rough S3, and when the ball 7 is hit on the right side of the fairway S2 near the predicted flight distance, the second convex on one side of the marker MB2. Since the altitude line H2 appears, it can be predicted that the ball 7 will return to the center from the edge of the fairway S2, and the player P can intuitively recognize the altitude of the point of interest.
