JP 2003-339929 A

  Improvements to conventional golf support devices have been made mainly by increasing the types of provision of information relating to golf or adding functions relating to golf. As the number of functions increases, the types of antennas and sensors used increase, and the entire apparatus becomes larger. It also includes functions that are not used in the places where they are taken, and there is a problem in portability in conjunction with an increase in the size of the device.

  In order to solve the above-described problems, a golf practice / support apparatus according to the present invention includes (1) a speed measurement sensor for measuring the speed of a moving object, a position measurement unit for obtaining a current position, and the position measurement unit. The golf course data storage means for storing and holding the course layout information of the golf course based on the current position obtained in step (1), a first control section for reading the course layout and outputting it to the first display section; and the speed measurement sensor And a second control unit that obtains the speed of the golf ball or club head that moves with the swing of the golf club based on the output, and outputs information based on the obtained speed to the second display unit. Based on the speed, the speed (swing speed / ball speed) itself may be used, or information obtained based on the speed (estimated flight distance, etc.) may be used.

  The speed measurement sensor corresponds to the Doppler sensor 31 in the embodiment. Like the Doppler sensor of this embodiment, the speed measurement sensor only needs to be able to detect and output information for measuring the speed, and the sensor may not necessarily be able to detect and calculate the actual speed. In the embodiment, the golf course data storage unit corresponds to the golf course data storage unit 12. In the embodiment, it is integrally mounted in the case, but it may be separately set in a server or the like as described in the modification.

  In the present invention, a golf support mode (in the embodiment, a golf navigation mode) in which the first control unit is operated and the course layout information is displayed on the first display unit based on the current position is executed, and output from the speed measurement sensor Is acquired by the second control unit, the swing speed and the ball speed are calculated, and the golf practice mode in which the result is output to the second display unit can be executed.

  (2) A separable first case main body and a second case main body are provided, and the second case main body includes the speed measurement sensor and communication for transmitting the output of the speed measurement sensor to the first case main body. An interface, and the first case body includes a communication interface that receives an output of the speed measurement sensor sent from the second body case, the position measurement unit, the first control unit, and the first case. 2 control units.

  Since the speed measurement sensor is not essential during the golf support mode (in the embodiment, the golf navigation mode) in which the first control unit is operated and the course layout information is displayed on the first display unit based on the current position, The second case body and the first case body are separated. Therefore, the first case body can be used alone, and it is compact and convenient to carry. In particular, when this golf support mode is operated, it is moving within the golf course, so it is preferable to be small and light because it does not interfere with carrying.

  On the other hand, at the time of practice, both the first case body and the second case body are used, the second control unit acquires the output from the speed measurement sensor, calculates the swing speed and the ball speed, and the results are displayed on the second display. The golf practice mode to be output to the club is activated. Usually, golf practice is actually hitting the golf ball at the driving range or swinging in the garden or other places at home, but without moving in a wide range, the second case body is connected to the first case body. Even if both are used equally and the whole apparatus becomes a little large, there is no problem. In addition, a controller and a man-machine interface (an input unit such as a switch and an output unit of a display unit) for executing the golf practice mode are incorporated in the first case body, and are also used for executing the golf support mode. By doing so, further miniaturization of the entire apparatus can be achieved.

  In addition, when the second control unit operates, the second control unit acquires the output of the speed measurement sensor, so that the second case main body and the first case main body operate and can communicate with each other. The second case main body may be used, or the first case main body may be used as in the embodiment. When the second display unit is installed in the first case main body, the actual display hardware component may be used both as the first display unit and the second display unit. Further, each display unit may be provided separately from each case body, and each control unit may output necessary information toward the display unit.

  (3) The first case body includes a determination unit that determines whether or not the second case body is connected, and the first case body is connected to the first case body when the second case body is not connected. It is preferable that the first control unit operates and the second control unit operates when the second case main body is connected to the first case main body. By automatically switching the operation mode (operating control unit) depending on the presence / absence of the second case main body, it is convenient because the user operates in a mode suitable for each connection situation without performing special mode switching. . Of course, even when a function for switching such a control unit that operates automatically is provided, such switching may be performed with priority, and execution in another mode may be performed by manual operation or the like.

  (4) The first display unit and the second display unit may be provided on the first case body. By arranging the first display unit and the second display unit together, it is possible to set the display unit in a place where the entire case is easy to see. In other words, even if both display units are installed separately, both display units are arranged in an easy-to-view location, so that the user can easily view even if either mode is displayed and displayed on any display unit. It can be secured. (5) Furthermore, the first display unit and the second display unit may be configured in common. This is preferable because not only the cost can be reduced by reducing the number of parts, but also the overall size can be reduced.

  (6) The first control unit and the second control unit may be configured by the same CPU. By configuring the control units for realizing the respective functions with the same CPU, it is possible to easily switch programs to be executed as well as simplifying and downsizing the apparatus configuration including the interface with the input / output unit.

  (7) A club type input unit for specifying a club type to be used is provided, and the second control unit estimates using the obtained speed and a coefficient associated with the club type specified by the club type input unit. A distance calculation function for calculating a flight distance may be provided, and the estimated flight distance obtained by the distance calculation function may be stored in the storage unit in association with the club type. The club type input unit is realized by the switch 19 in the embodiment. The storage unit may be provided in the first case body as in the embodiment. Since the estimated flight distance measured in the golf practice mode is stored in the storage unit of the first case body, the data stored in the storage unit can be read and written even after the second case body is removed.

  (8) The first control unit draws a mark at a position corresponding to the current position obtained by the position measurement unit in the course layout displayed on the first display unit, and acquires the estimated fly of the club type to be used. It is preferable to have a function of reading the distance from the storage unit and displaying the distance on the first display unit. The mark corresponds to the self icon I of the embodiment. By displaying the current position and the estimated flight distance, it is possible to easily understand whether or not the target club location is reached in the selected club type.

  (9) The estimated flight distance may be displayed by drawing a circle centered on the mark and having the estimated flight distance as a radius. By drawing with a circle, it can be visually and intuitively recognized, and the position where the ball flies can be predicted when it is slanted and hit diagonally.

  (10) The estimated flight distance displayed on the first display unit may be at least one of an average value, a maximum value, and a minimum value. By displaying the average value, it is possible to predict the arrival position when it flies normally, and by displaying the maximum value and the minimum value, the arrival of the ball when it is too good or hit This is preferable because the position can be predicted.

  (11) The second control unit has a function of displaying a hole layout of a golf course on the first display unit or the second display unit, and the distance calculation unit centered on a designated point on the hole layout. A ball stop point candidate display function for drawing a circle having a radius with the estimated flight distance obtained in step (b), wherein the designated point is a designated point in a tee ground on a hole layout or the ball stop point candidate display. It may be a point specified on the circumference of the circle drawn by the function. The hole layout may be a virtual golf course or a real golf course. In either case, it is possible to perform practice closer to actual golf play.

  (12) The hole layout may be for an actual golf course stored in the golf course data storage unit. This is preferable because simulation can be performed using the actual hole layout of a golf course.

  (13) The second control unit has a function of displaying a course layout of an actual golf course stored in the golf course data storage unit on the first display unit or the second display unit, and on the course layout. Centering on the specified point, find the intersection of the circumference of the circle whose radius is the estimated flight distance obtained by the distance calculation unit and the reference line set in the course layout, and based on the obtained intersection And determining a ball stop point and displaying the determined point. In this way, since the stop position of the ball can be automatically determined, the user does not have to specify the stop position for each shot, which is convenient.

  (14) The reference line may indicate a capture route of the course layout hole. In this case, the intersection of the capture route and the circumference can be set as the stop position, and the position can be easily obtained.

  (15) The capture route is a line connecting from a predetermined position on the tee ground to a predetermined position on the green, and when the line is non-linear, it is specified by one or more reference points indicating the position where the direction changes. It is good to constitute so that. In this way, a strategy route can be set based on a small amount of information.

  (16) The reference line may be a fairway boundary line and / or a course boundary line of the course layout. In this case, the intersection between the two boundary lines and the circumference can be obtained, and a predetermined position (for example, the middle point) on the line (string / arc) connecting the two intersections can be set as the stop position. .

  (17) When receiving the function of displaying the course layout of the golf course on the first display unit or the second display unit and the designation of the target point on the displayed course layout, the distance from the current position to the target point Is used to access the estimated flight distance storage means storing the estimated flight distance for each club type and to hit the target point based on the calculated distance and the estimated flight distance for each club type. It is preferable to have a function of determining a suitable club type and notifying information on the determined club type. By doing so, the club type can be easily selected.

  (18) You may comprise so that the estimated flight distance of the determined club type and the function which alert | reports the calculated | required distance may be further provided.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. The golf practice / support device of this embodiment displays the course layout of the actual golf course, measures the current position, moves the player, and notifies the current position and the remaining distance to the green in real time, such as golf navigation. A golf support function and a golf practice function for obtaining and outputting the head speed of the golf club, the ball speed of the actually hit ball, the estimated flight distance, and the like are provided.

  1 and 2 are diagrams showing an example of a usage state of the golf practice / support apparatus of the present invention. As shown in FIGS. 1 and 2A, the golf practice / support device 10 is installed at a predetermined rear position of the golfer 1 swinging the golf club 2. A specific installation position is a position where the detection range of the golf practice / support device 10 includes a point where the head 2a of the golf club 2 during the swing moves at the maximum speed. As an example, as shown in FIG. 1, the vicinity of the lowest point of the movement trajectory 3 of the head 2a of the golf club 2 is the impact position with respect to the ball 4, and the movement speed of the head 2a is normally the maximum speed near the position. For this reason, it is on the tangent 5 of the lowest point of the movement locus | trajectory 3 which concerns, and the back of the golfer 1 is made into an installation position. In this case, the distance between the ball 4 and the golf practice / support device 10 is about 1 m. As will be described later, since the Doppler sensor is built in the golf practice / support apparatus 10, the antenna opening surface 11a of the Doppler sensor is installed so as to face the ball 4 (facing the tangent 5). The

  This installation position corresponds to the case where the club used is a club other than the putter, and the ball 4 may not be provided. In other words, when the golf practice / support device 10 actually hits the ball 4, the golf practice / support device 10 measures both the head speed and the ball speed at the same time each time it swings, and does not place the ball 4. If you do not actually hit), only measure the head speed.

  On the other hand, when the club used is a putter, the installation position as shown in FIG. In other words, the golf practice / support device is located in front of the golfer 1, more specifically, at a position about 20 cm away from the front side of the ball 4 as viewed from the golfer 1 and about 20 cm ahead in the launch direction of the ball 4. 10 is put. And the opening surface 11a of the antenna of the golf practice / support device 10 is made to face about 1 m of the rolling destination of the ball 4. In this mode of use, it is essential that the golfer 1 actually hits the ball 4 in order to measure the ball speed. Then, the speed measurement area of the golf practice / support apparatus 10 is set to a certain area where the ball B rolls, and there is no movement locus of the head 2'a of the putter 2 'in the measurement area. Measurement is not possible. Therefore, only the velocity of the ball is measured.

  FIG. 3 shows a preferred embodiment of the golf practice / support apparatus 10 according to the present invention. The golf practice / support apparatus 10 includes a first case body 21 and a second case body 22, and both the case bodies 21 and 22 are detachable. A connection mechanism is provided on the side surfaces of both case bodies 21 and 22, and the side surfaces are in contact with each other while being aligned. When connected, it forms one housing. Along with this connection, the first connector 23 and the second connector 36 disposed on the respective side surfaces are coupled and electrically connected to each other so that data can be transmitted and received and power can be supplied. Further, the first and second case bodies 21 and 22 may be mechanically coupled by connecting the first and second connectors 23 and 36.

  Elements constituting a golf support function such as golf navigation are incorporated in the first case body 21. That is, in the first case body 21, a position measurement unit 11 that receives a GPS signal and obtains a current position, a golf course data storage unit 12 that stores golf information such as a course layout of the golf course in advance, and a position Based on the current position information from the measurement unit 11, the golf course data storage unit 12 is accessed, and a control unit 13 that performs control for acquiring information about the golf course and outputting it to the output device, a display device 14 that constitutes the output device, A speaker 15, a connection state detection unit 16 that detects whether or not the second case main body 22 is connected, and a battery 17 that serves as a power source when carried. Further, the first case body 21 also includes a storage device 18, various switches 19, and a communication interface 20.

  The golf course data storage unit 12 is configured by a recording medium such as an internal memory or a removable external recording medium (such as a micro SD memory card). The golf information stored in the golf course data storage unit 12 includes data on the actual golf course (course layout of each hole, the position of an object on the course such as a golf course green or a bunker), and the like. These pieces of information can be the same as those disclosed in, for example, Japanese Patent Application Laid-Open No. 7-57189 and Japanese Patent Application Laid-Open No. 2003-339929.

  The control unit 13 includes a microcomputer including a CPU, ROM, RAM, flash memory, various peripheral circuits, interfaces, and the like. When the power switch is turned on, the control unit 13 is supplied with power from the battery 17 and starts operation. The control unit 13 develops the OS and application program recorded in the flash memory on the RAM by the boot loader recorded in the ROM, and executes the OS and application program on the RAM, thereby executing various processes shown below. To implement various functions.

  The storage device 18 records the calculation results, and may be an internal storage device that cannot be attached or detached, or a slot portion (including a read / write function) for attaching a removable recording medium such as an SD memory card. . The recording medium / device constituting the storage device 18 may be shared with the golf course data storage unit 12 in an actual device.

  The connection state detection unit 16 detects whether or not the second case main body 22 is attached to the first case main body 21, for example, the side surface of the first case main body 21 (the connection surface with the second case main body 22). ), A pressure sensitive / contact type switch (sensor) such as a limit switch is arranged, and when the case main bodies 21 and 22 are connected, the switch is turned on (or off) and the case main bodies 21 and 22 are separated. This can be realized by setting the switch to be turned off (or on) when the second case body 22 is removed from the first case body 21. At this time, the switch is preferably in a state where it is flush with the surface of the first case body 21 or slightly inside, and the switch is pushed by a protrusion or the like provided on the second case body 22. If it does in this way, when carrying the 1st case main body 21 independently, it can suppress that the said switch is pushed accidentally and it is judged that the 2nd case main body 22 is connected erroneously. Moreover, it is not restricted to the thing which contacts directly in this way, A non-contact type thing, such as a proximity sensor, can also be utilized. The detection result of the connection state detection unit 16 is given to the control unit 13.

  The display device 14 is formed from an LCD, an organic EL display, or the like. The battery 17 may be a primary battery such as a dry battery, or a rechargeable secondary battery such as a rechargeable battery. The switch 19 includes a power switch for turning on / off the power and an operation switch for giving various instructions. Further, a touch panel may be provided on the surface of the display device 14, and the touch panel may be used as an operation switch.

  The control unit 13 determines the operation mode based on the detection result from the connection state detection unit 16. That is, the control unit 13 obtains an application program for realizing a golf support function (golf navigation mode) such as golf navigation, the head speed of the golf club, the ball speed of the actually hit ball, the estimated flight distance, and the like. An application program for realizing an output golf practice function (golf practice mode) is provided, and these are switched and executed. In the present embodiment, when the first case main body 21 is used alone without being connected to the second case main body 22, the control unit 13 executes the golf navigation mode and sets the second case main body 22 to the first case main body 21. In the state connected to the case main body 21, the control unit 13 executes the golf practice mode.

  As described above, the control unit 13 automatically switches between the golf navigation mode and the golf practice mode based on the detection result of the connection state detection unit 16. The mode may be switched based on the instruction. In this case, a manual mode switching function based on a user instruction and an automatic switching function can coexist. That is, for example, when the first case body 21 and the second case body 22 are connected, the control unit 13 automatically switches to the golf practice mode based on the detection result from the connection state detection unit 16. When the golf navigation mode is selected by the mode switch, the control unit 13 switches the program to be executed to the golf navigation mode. Thus, for example, the first case main body 21 and the second case main body 22 are taken to the golf course, practiced in a state where both are connected before play, and the case main bodies 21 and 22 are connected. When you round, you can switch to golf navigation mode and carry it on the course. That is, the user can prevent the second case body from being misplaced by removing the second case body 22 for use in the golf navigation mode.

  Based on the position information (longitude / latitude) from the position measurement unit 11, the control unit 13 that is executing the golf navigation mode accesses the golf course data storage unit 12 and reads information on the golf course currently being played. Then, the corresponding course is read from the current position information and drawn on the display device 14. An example of the display screen drawn on the display device 14 is as shown in FIG. In this figure, a self icon I indicating the place where the user is present is drawn at the center of the display screen, and the layout of the hole currently being played is drawn so that the green is on top. As a result, it is possible to know the direction toward the green and the position, size, and shape of the pond, bunker, etc. existing around the green. Further, a concentric circle line L is drawn on the hole layout with the self icon I as the center. This allows you to understand the approximate distance to the pond and bunker. In this way, by displaying the course layout, the user can check the strategy for each hole even in the first course.

  A remaining distance display area R1 is set at the lower right of the screen. That is, in the golf course data storage unit 12, the position of the green edge and the position of the green center are registered as green information. Therefore, the control unit 13 obtains the distance between the current position and the center of the green, and displays the remaining distance to the center of the green (“149” in the figure). Further, the intersection between the current position and the center of the green and the green edge is obtained, the distance between the obtained intersection and the current position is obtained, and the remaining distance to the green edge is displayed (“132” in the figure). "). Furthermore, a directional arrow Y is drawn from the current position toward the center of the green.

  In addition, any point can be registered based on a switch operation or the like. Specifically, the control unit 13 acquires a current position from the position measurement unit 11 when a point registration process by a switch operation or the like is received, and registers the point. This arbitrary point can be used, for example, to register a point where the ball is actually hit. When an arbitrary point registered in such a manner exists in the hole layout displayed on the display screen, the point registration icon I0 is drawn at the corresponding position. Further, the distance from the registered position to the current position of the current icon I is obtained and displayed in the flight distance display area R2 prepared at the lower left of the display screen ("138" in the figure). In addition, a plurality of spot registrations can be performed, and each piece of location information registered for each spot is recorded in the storage device 18 in the registration order for each hole. Thereby, by registering the position where the ball was hit each time, the locus of play on the actual golf course can be recorded, and each hole layout is drawn on the display device 14 together with the point registration icon I0. Thus, the actual trajectory of the play can be confirmed on the display screen.

  In the upper area of the display screen of the display device 14, an icon I1 indicating the remaining battery level, an icon I2 indicating the hole number currently being played, and an icon I3 (L ( (Left side) / R (right side)) and an icon I4 (yd (yard) / m (meter)) indicating the unit of distance display. Further, the time is displayed at the right end of the information area.

  Further, as will be described later, in this embodiment, a golf practice mode is provided, and the estimated flight distance for each club type can be recorded in the golf practice mode. Therefore, when using as the golf navigation mode, when the controller 13 recognizes the designation of the club type (number), the controller 13 reads the estimated flight distance for the designated club type from the storage device 18 and displays it on the course layout display screen. Overlapping display. At this time, the estimated flight distance may be displayed as a number as a text, or a circle having a radius corresponding to the estimated flight distance on the display screen may be drawn with the self icon I as the center. In particular, when the estimated flight distance is indicated by a circle, whether the club type selected in relation to the remaining distance is appropriate, or if the launch direction deviates from the target direction, hazards such as bunker or pond, rough This is preferable because it is possible to visually and intuitively understand the possibility of being caught in

The club type can be specified by operating a club selection switch for selecting and specifying a club type provided as a type of switch 19. Then, the control unit 13 calculates the estimated flight distance from the selected club type and information such as the head speed and the ball speed. Specifically, when the controller 13 recognizes that the club selection switch is pressed (for example, “short press”), the controller 13 circulates the club types in the following order.
“1W → 3W → 5W → 3I → 4I → 5I → 6I → 7I → 8I → 9I → W (Wedge) → Pt (Putter)”

  Further, the control unit 13 currently selects “W, I, t and 7 segments” as appropriate in the club type display area set at a predetermined position on the display screen of the display device 14 in accordance with the circulation of the club type. Displays the type of club being used. That is, when wood (1W, 3W, 5W) is selected, the number selected as “W” is displayed and the iron (3I, 4I, 5I, 6I, 7I, 8I, 9I) is selected. If “I” is selected, the number selected as “I” is displayed. If the wedge (W) is selected, only “W” is displayed and the pattern (Pt) is selected. Displays only “t” (P can be displayed together with 7 segments).

  Furthermore, as will be described later, in the case where a function for obtaining the maximum value and the minimum value of the estimated flight distance measured in the golf practice mode is provided, the control unit 13 performs the highest flight distance in addition to the estimated flight distance (average value). It is good to display the value and the minimum value together. As an example of the display layout in such a case, as shown in FIG. 5, a concentric circle (S0: average value, SH: maximum value, SL: minimum value) centered on the self icon I can be drawn. This makes it possible to more accurately predict the range of the arrival point of the ball when the ball hits too well and jumps too much (maximum value) or fails to hit (minimum value), and the club type can be selected appropriately.

  As described above, in the golf navigation mode, the control unit 13 draws the course layout of the hole that is currently being played on the display screen of the display device 14, and displays a self-icon at a point corresponding to the current position on the course layout. Draw I. Therefore, when an arbitrary point on the displayed course layout is designated as a point (target point) to be hit, the control unit 13 calculates the distance from the current position to the designated point and hits the distance. It is preferable to have a function of determining a suitable club type and displaying information on the determined club type. At this time, the distance to the point may be displayed together.

  That is, as will be described later, information (average value, maximum value, minimum value, etc.) relating to the estimated flight distance for each club type is recorded in the storage device 18 or the like. Therefore, the calculated distance to the point is compared with the estimated flight distance (for example, average value) of each club type to determine the closest club type. Further, the determination of the club type is not limited to this, and the club type having the closest estimated flight distance among those having the larger estimated flight distance may be used.

  Then, the control unit 13 may display the type of club type and the estimated flight distance as information on the determined club type. When the estimated flight distance is displayed together with the average value and the maximum value and the minimum value, the distance to the point is also displayed, so that it is possible to easily determine whether or not the club type is appropriate.

  Furthermore, in the golf navigation mode, the actual play can be recorded by using the above-described point registration function and the club type designation function. When hitting the ball, the user operates the switch 19 to register the location of the hit location and register the club type to be used. The control unit 13 registers the position where the ball was hit and the club type used at that time in the storage device 18 in order from the first hit. Since the flight distance of the ball hit this time is the distance between the position registered this time and the position registered next time, the control unit 13 calculates the actual flight distance, , Register the club type and the actual flight distance. Thereby, the control unit 13 obtains the average flight distance, the maximum flight distance, and the minimum flight distance for each club type and displays them on the display device 14. At this time, for example, by displaying the actual flight distance and the estimated flight distance together (simultaneously / alternately), a deviation between the estimated flight distance and the actual flight distance can be recognized. During play, the user can display the estimated flight distance and actual flight distance one after another to check the deviation, and whether the day's state is flying or not flying compared to the normal estimated flying distance. The club type to be actually used can be appropriately selected based on the estimated flight distance + club type displayed at the time of play after that day.

  Further, although the flight distance displayed when the club type is selected, the actual flight distance may be used instead of the estimated flight distance acquired in the golf practice mode as described above. The estimated flight distance is simply and conveniently calculated based on the swing speed, the ball speed, and the like, and does not necessarily represent the actual flight distance due to a coefficient used at the time of calculation. Therefore, as the flight distance displayed when the club type is selected, the control unit 13 has a function of displaying information based on the past actual flight distance for the same club type of the user. The information based on the actual flight distance in this case may be an average value of the actual flight distance, or may be the maximum flight distance or the minimum flight distance of the actual flight distance in the same manner as the estimated flight distance. Further, which of the actual flight distance and the estimated flight distance is output can be selected alternatively based on the switch operation, or both can be displayed.

  Moreover, the history data of the actual flight distance is registered in association with date (date and time) information, so that, for example, the control unit 13 can display information based on the actual flight distance based on today's play. In this way, since the actual flight distance closer to the play environment such as the player state and the course state of the day is displayed, it is easy to make a strategy. In particular, in the case of club types that are used many times, such as drivers on the tee ground and clubs that are good on the fairway, if you can check the actual flight distance of the day, Useful information can be provided to make an appropriate choice of count.

  Furthermore, since the control unit 13 recognizes where the golf course currently being played is, the information based on the actual play (the hit position, the club type, the flight distance, etc.) It is good to register in association with the information (golf course name, identification code, etc.) specifying the completed golf course. In this way, when playing multiple times at the same golf course, information based on the actual flight distance at that golf course (average flight distance, maximum flight distance, minimum flight distance, etc. for each club type) is displayed. Good.

  Even when the mode for displaying the actual flight distance is selected, there may be no actual flight distance data for the selected club type. A function for reading and displaying the distance may be provided. In particular, as described above, when the actual flight distance limited to the play of the day or the actual flight distance limited to the golf course is selected, the club type selected for the next hit may be used for the first time. Since there is, it is good to display the estimated flight distance as reference information. In that case, it displays so that it may be known that it is an estimated flight distance.

  Further, by using a removable recording medium such as a memory card as the storage device 18 or using a communication interface with a USB or other predetermined wired / wireless external device, the actual play stored in the storage device 18 can be performed. Information collected and recorded based on this can be transferred to an external device such as a personal computer for management or display on a large screen.

  Within the second case body 22, a microwave Doppler sensor 31 having an output frequency of 24.15 GHz and an output signal of the Doppler sensor 31 (a signal corresponding to a movement of 6 mm of the golf club head) is amplified. Golf such as an amplifier 32 and a comparator 33 that compares the signal amplified by the amplifier 32 with a reference value and outputs a Doppler pulse (a high level signal when the reference value is equal to or higher than the reference value and a low level signal when the signal is lower than the reference value). A component used only for the practice mode, a communication interface 34 necessary for transmitting and receiving data to and from the first case body 21 side, and a second connector 36 are provided. Further, the side surface of the second case main body 22 is also provided with a protrusion 35 for causing the connection state detection unit 16 in the first case main body 21 to detect the connection. A control unit such as a CPU that performs arithmetic processing and control for executing the golf practice mode, a switch as a man-machine interface, and an output device (display device) are mounted on the first case body 21. I also use it.

  As a result, when using the golf navigation mode, the second case body containing the Doppler sensor unnecessary for the mode is removed and the first case body 21 is operated alone, so it becomes compact and portable to the golf course. And it doesn't get in the way when you carry it around. On the other hand, when the golf practice mode is used, by connecting the second case main body 22 and the first case main body 21, it is possible to use a controller and a man-machine interface mounted on the first case main body 21. Even if the entire apparatus including the case main body is not so large, the apparatus can execute two modes, but by sharing many devices and parts, the number of parts can be reduced and the cost can be reduced.

  The sensor and various electronic circuits in the second case body 22 operate based on the battery 17 in the first case body 21. That is, by connecting the first case body 21 and the second case body 22, power is supplied from the first connector 23 to the second case body 22 via the second connector 36.

  The analog signal amplified by the amplifier 32 and the pulse signal output from the comparator 33 are given to the control unit 13 via the communication interface 34 → the second connector 36 → the first connector 23 → the communication interface 20. The analog signal amplified by the amplifier 32 is converted into a digital signal by an A / D converter built in the control unit 13.

  When the 2nd case main body 22 is connected to the 1st case main body 21, the control part 13 performs golf practice mode. Therefore, the control part 13 calculates | requires swing speed based on these signals. That is, as described above, when the power is turned on, the analog waveform obtained by amplifying the output of the Doppler sensor 31 by the amplifier 32 is threshold-processed by the comparator 33 and encoded. Is input. Therefore, the control unit 13 obtains the Doppler pulse cycle using a built-in counter, and obtains the speed of the moving body. When the moving body is a golf club head, the head speed is obtained, and when the moving body is a ball, the ball speed (initial speed) is obtained. As this specific calculation algorithm, for example, various calculation algorithms can be used in addition to the technique disclosed in JP-A-6-86845.

  Furthermore, in order to specialize in the speed measurement of the head speed during the swing of the golf club in this apparatus, the speed data from the start to the end of the swing is temporarily stored, and then the maximum speed of the swing is calculated from the stored data. Good.

  Further, when only swinging without placing the ball, the control unit 13 can easily obtain the head speed by the known algorithm. Further, in this embodiment, when the ball is actually hit, the control unit 13 obtains the ball speed and the head speed at the same time. This is because the moving speed of the head accompanying the swing of the golf club gradually increases from the start of the swing, reaches a maximum speed before and after hitting the ball, and then gradually decreases. On the other hand, since the ball remains stopped at the beginning of the swing of the golf club, the moving speed becomes 0, and when the head hits and strikes, the moving speed increases. There is a difference between the peak of the speed change of the head speed and the peak of the speed change of the ball speed (the peak of the ball speed occurs with a delay). Therefore, since two speed peaks occur, each speed can be obtained. Specifically, for example, both speeds can be obtained using a technique such as JP-A-6-86845.

  The ball speed is not limited to that obtained based on the Doppler pulse as described above. For example, a signal output from the amplifier 32 (a signal obtained by amplifying the Doppler signal output by the Doppler sensor 31) is A / The D-converted data may be separately stored in a memory, and may be calculated by performing frequency spectrum analysis (for example, fast Fourier transform (FFT)) on the A / D conversion data stored in the memory. The golf ball is small and far from the head. Even in the case of an input signal having a disadvantageous S / N ratio due to a small reflected wave due to a small reflected wave, the FFT disperses the noise component over the entire frequency by frequency decomposition, and the signal component is extracted as a line spectrum. A sufficient signal-to-noise ratio for analysis can be ensured.

  Moreover, it is preferable to start accumulation in the memory on condition that a swing is detected. In this way, there is no need to constantly accumulate, and the load required for memory update processing is reduced. At this time, the function for discriminating the swing may be discriminated that the swing has occurred when the period of the Doppler signal based on the Doppler signal output by the Doppler sensor 31 is a periodic pattern corresponding to the swing of the golf club. The control unit 13 displays the obtained speed on the display device 14 or stores it in the storage device 18.

Further, the present apparatus includes a club selection switch as a switch 19 for selecting / designating the club type in accordance with the club to be used. The button elements constituting the switch 19 are the same as those used in the golf navigation mode, and the control unit 13 recognizes different instructions even when an operation is performed on the same switch depending on the mode being executed. Then, the control unit 13 calculates the estimated flight distance from the selected club type and information such as the head speed and the ball speed. Specifically, when the controller 13 recognizes that the club selection switch is pressed (for example, “short press”), the controller 13 circulates the club types in the following order.
“1W → 3W → 5W → 3I → 4I → 5I → 6I → 7I → 8I → 9I → W (Wedge) → Pt (Putter)”

  Further, the control unit 13 currently selects “W, I, t and 7 segments” as appropriate in the club type display area set at a predetermined position on the display screen of the display device 14 in accordance with the circulation of the club type. Displays the type of club being used. That is, when wood (1W, 3W, 5W) is selected, the number selected as “W” is displayed and the iron (3I, 4I, 5I, 6I, 7I, 8I, 9I) is selected. If “I” is selected, the number selected as “I” is displayed. If the wedge (W) is selected, only “W” is displayed and the pattern (Pt) is selected. Displays only “t” (P can be displayed together with 7 segments).

  The control unit 13 has an estimated flight distance calculation function. This estimated flight distance calculation function calculates the estimated flight distance from the ball speed and the club type used when actually hitting the ball, and calculates the estimated flight distance from the head speed and the club type used when swinging. It is a function. Specifically, a coefficient for the ball speed and a coefficient for the bed speed are set in advance for each club type (a table of club type-coefficients is provided), and a coefficient corresponding to the club type is set for the ball speed or the head speed. The value multiplied is taken as the estimated flight distance. The presence / absence of the ball may be designated manually by manual operation, or various sensors may be provided and automatically recognized by the apparatus.

  The measurement result is stored in the storage device 18. The control unit 13 reads the past history stored in the storage device 18 in accordance with an instruction based on the operation of the switch 19 and displays it on the display device 14 or obtains an average value of the past measurement results and displays it. And a function of displaying on the device 14. The average value is the average value of the selected club type from the history (a maximum of 500 records) recorded in the storage device 18. Further, the control unit 13 extracts the maximum value and the maximum value for each club type, and displays them together.

  Further, as described in the golf navigation mode, when the actual flight distance is calculated by point registration or the like and recorded together with the used club type, the control unit 13 performs the same club type stored in the storage device 18. The actual flight distance is read out, a correction value is calculated from the difference / ratio with the estimated flight distance, and the correction value is corrected when calculating the estimated flight distance. In addition, the actual flight distance, for example, the driver or the like often makes a full shot even in actual play, but when the iron becomes a large count, the half shot is often performed from the remaining distance or the like. Therefore, in the golf navigation mode, information on whether or not to use it as data for obtaining the average value of the actual flight distance (whether or not a full shot has been taken) is recorded as additional information, and this correction value is When obtaining, it is preferable to use the average value of the actual flight distance when a full shot is taken from the additional information. The display of the actual flight distance in the golf navigation mode may also be obtained from those that meet certain conditions such as a full shot.

  Next, the “training mode” which is one of the golf practice modes will be described. The training mode assumes a virtual golf course and goes around the virtual course as if it were a game. There are “full round” that turns 1 to 18 holes in one set, and “hole designation” that is completed with an arbitrarily designated hole. . By operating a hole designation switch prepared as the switch 18, a play style of “full round” or “hole designation” is selected. In this embodiment, since 18 holes are prepared, for example, every time the hole designation switch is pressed, “full round” → “hole designation (No. 1)” → “hole designation (No. 2)” →. … "Hole designation (18th)" → "Full round" → ... and so on. Of course, it can be specified more easily by increasing the number of switches.

  The course layout (for all 18 holes) of the virtual course used in the training mode is stored in the storage device 18 of the first case body 21 or the golf course data storage unit 12 and displayed on the display device 14.

  One example of the layout of one hole is the hole layout shown in FIG. And a user advances a game based on the layout figure of the hole to play. Further, the hole on the software executed by the control unit 13 simply divides each zone according to the distance as shown in FIG.

  This training mode reads the virtual golf course (course) map data stored in memory (distance from tee ground to cup, position of penalty zone such as OB / water hazard, etc.), and the head accompanying the swing of the golf club The estimated flight distance is calculated from the speed or ball speed, the remaining distance to the cup is calculated, the calculated remaining distance and the number of hits so far are displayed on the display device 14, and finally the cup-in (remaining distance is a threshold value). Repeat until:

  In other words, the control unit 13 calculates the estimated flight distance based on the head speed or the ball speed, and subtracts the calculated estimated flight distance from the remaining distance at the ball shot position to determine the ball stop point (the next ball shot). The remaining distance at the position) is calculated, and the number of strokes is added by “1 stroke”. The control unit 13 displays the obtained remaining distance and the number of hits on the display device 14. In addition, when the ball stop point (the next ball shot position) obtained by adding the estimated flight distance to the current position is a penalty area such as a water hazard or OB, the control unit 13 blinks the remaining distance for several seconds, The penalty is added to the number of strokes and the remaining distance is corrected, and the corrected number of strokes and remaining distance are displayed. When entering the water hazard, the remaining distance is obtained by setting the boundary position on the tee ground side of the water hazard to the shot position of the next ball and calculating the distance from there to the cup. Further, when the ball enters the OB zone, the previous shot position is set as the next shot position, and the distance from there to the cup is set as the remaining distance after correction. That is, the remaining distance at the time of the previous shot (the distance obtained by adding the estimated flight distance associated with the previous shot to the current remaining distance) is the remaining distance after correction.

  When the stop point of the ball becomes a green area (green-on), the microcontroller 14 lights the “NICE ON” logo on the display device 14. On the green, the unit of distance is changed from “yard” to “m” (meter).

  Furthermore, when the remaining distance becomes 1 m or less, it is regarded as a cup-in, and the control unit 13 performs display for expressing the cup-in on the display device 14 for several seconds. In addition, when the remaining distance is in the range of 1 to 3 m, the control unit 13 displays “OK” on the display device 14 for several seconds.

  Furthermore, the course layout used in this training mode has a function of using the course layout of an actual golf course stored in the golf course data storage unit 12. Thus, for example, at a golf driving range or the like, it can be simulated and enjoyed as if it were playing at an actual golf course, or used for prior practice of actual play.

  Actually, the user selects a golf course to be used from a menu screen (not shown). As described above, the golf course data storage unit 12 stores data about the actual golf course as one of the golf information (course layout of each hole, the position of the target object on the course such as the golf course green and bunker), etc. Therefore, the control unit 13 accesses the golf course data storage unit 12, reads the course layout for the designated golf course, and draws the course layout of a predetermined hole on the display device 14. At this time, as for the predetermined hole to be drawn, in the same way as the virtual golf course in the training mode described above, when “full round” in which all of the holes are played in order from the first hole is selected, the first hole is drawn first. After that, when the play of the hole is finished, the next hole becomes the predetermined hole. When “hole designation” for playing the designated hole is selected, the designated hole becomes a predetermined hole to be drawn.

  The user designates a place (shot position) for hitting the ball in the hole to be played drawn on the display device 14. This can be specified, for example, by providing a touch panel on the display screen of the display device 14 and touching an arbitrary point on the course layout drawn on the display device 14. The control unit 13 sets a course layout point touched by the touch panel as a shot position, and draws a predetermined icon (mark) at the shot position. The user can confirm whether the shot position is correct by looking at the icon. If the position of the drawn icon is different from what the user expects, the display device 14 (touch panel) is touched again to reset the shot position.

  In actual golf play, the first shot is a tee shot from the tee ground. Therefore, as the position touched by the user, the position of the tee shot can be specified by touching an arbitrary point in the tee ground on the course layout drawn on the display device 14. In addition, when an area outside the tee ground is touched, it is possible to practice shots after the second shot in actual golf course play. In other words, by practicing aiming at the green from various points by designating various points near the green, or by practicing the strategy after the second shot assuming a missed tee shot Can do.

  Furthermore, since the first shot in actual play is a tee shot from the tee ground, a predetermined position in the tee ground (predetermined positions such as the center in the area, the center of the front end, etc.) is stored in the golf course data storage unit 12 in advance. ) May be registered, and the control unit 13 may determine a predetermined position in the registered tee ground as a read shot position. In such a case, since the shot position is automatically determined, there is no need for the user to specify manually.

  The control unit 13 recognizes the club type designated via the club selection switch, obtains the estimated flight distance from the swing speed or the ball speed by the estimated flight distance calculation function, and uses the determined shot position as a center for the course layout. Draw concentric circles of estimated flight distance on the display.

  The user designates a predetermined position on the concentric circle of the displayed estimated flight distance. When the ball is actually hit, the direction of the actually flew ball is estimated, and the intersection of the flew direction and the concentric circle is designated. In addition, in the case of only swinging, an arbitrary point is designated. This designation is performed by touching a corresponding position on the displayed concentric circle when a touch panel is superimposed on the display device 14. When there is no touch panel, the control unit 13 draws a mark (cursor) indicating a ball stop position candidate at an arbitrary point on the displayed concentric circle. Then, the user can specify the position by operating a cursor key or the like prepared as the switch 19, moving the mark indicating the stop position candidate along the concentric circle of the estimated flight distance, and selecting it at an arbitrary position. .

  This designated point is a point (shot position) where the next ball is hit. Further, the display of the flight distance, the remaining distance to the hole, and the like is the same as in the golf navigation mode or the golf practice mode. This process is repeated until hole out. In addition, when placed on the green, as in the training mode described above, if a predetermined distance is reached to the cup position, it may be regarded as a cup-in, or one stroke may be added to make an OK pad.

  This simulation data is recorded in the storage device 18 and taken into a personal computer or the like as an external device, and can be displayed, stored and processed by the personal computer. In addition, when actual data of actual play is stored for the course being simulated, the control unit 13 reads out the average value, maximum value, minimum value, etc. of the data, and displays and compares them during this simulation. Display.

  The simulation result using the course layout of the actual golf course in this way is stored in the storage device 18, and when executing in the golf navigation mode on the actual golf course, the control unit 13 stores the result. The simulation result stored in the device 18 can be read and output to the display device 14. As a result, the simulation result can be confirmed during actual play, and can be used as a reference during hole capture.

  FIG. 7 and subsequent figures show other algorithms in the case of executing a training mode (simulation) using an actual golf course course layout. In the embodiment described above, the stop position of the ball is performed by the user specifying an arbitrary point on the concentric circle corresponding to the estimated flight distance centered on the shot position. This is because the apparatus can calculate the estimated flight distance of the shot ball, but cannot detect the direction in which the ball flew. Therefore, in the above-described embodiment, the designation is made by a manual operation by the user. When the user actually hits the ball in this way, the stop position can be determined in accordance with the flight direction, so that a simulation closer to the actual play can be performed. On the other hand, it is complicated in that it is necessary to specify the stop position of the ball every time it is shot. Therefore, in the embodiment shown in FIG. 7 and subsequent figures, the golf practice / support device 10 (control unit 13) is provided with a function of automatically determining the stop position of the ball.

In order to realize the function of automatically determining the stop position of such a ball, the embodiment described above in relation to the course layout of each hole is used as the data about the actual golf course stored in the golf course data storage unit 12. In addition to the above, position information for specifying the position of the boundary line between the fairway and the rough is also registered. The position information for specifying the position of the boundary line is information indicating the absolute position of an arbitrary point on the boundary line and the arrangement order of the points. Accordingly, the boundary line between the fairway and the rough can be reproduced by connecting the absolute positions of adjacent points with a straight line or the like. As the number of points on the boundary line to be registered increases, it is possible to reproduce a shape closer to the actual fairway shape. Also, register boundary information for ponds and other water hazards, position information for specifying the outer periphery of the green, and position information for specifying the position of the outer periphery of the hole for specifying the area of each hole To do. These water hazard boundary lines, position information for specifying the outer periphery of the green, and position information for specifying the position of the outer periphery of the hole are positions for specifying the boundary line of the fairway and the rough. Similar to information, it is information indicating the absolute position information of arbitrary points on each boundary line or outer periphery and information indicating the arrangement order of the points. Further, the position information (absolute position information) of the cup is also registered in the golf course data storage unit 12.
An algorithm for implementing the function of automatically determining the stop position of the ball is as follows.

[Determination of tee shot position]
First, as shown in FIG. 7A, the control unit 13 determines the position P of the tee shot. This determination may be performed in response to the user's designation as in the above-described embodiment, or may be performed at a predetermined position in the tee ground registered in the golf course data storage unit 12 (the center in the area, the center of the front end, etc. (A preset position) may be automatically set.

[Determination of the ball stop position: based on both sides of the fairway]
Next, the control unit 13 recognizes the club type designated via the club selection switch, and obtains the estimated flight distance from the swing speed or the ball speed by the estimated flight distance calculation function. The control unit 13 obtains intersections A and B between the concentric circle S of the estimated flight distance r centered on the shot position P and the sides of the fairway F (boundary lines with the rough), and the intersections A and B are obtained. A midpoint Q of the connecting virtual line KS is obtained. That is, the control unit 13 extracts points registered as position information in order to specify a boundary line with the fair weight rough existing in the vicinity of the circumference of the concentric circle S, and from the information indicating the arrangement order of the points, the concentric circle S The two continuous points that exist across the circumference of the circle are obtained, and the intersection between the line segment connecting the two points and the concentric circle S is obtained. The control unit 13 obtains the intersections A and B by executing the process on both sides of the fairway F, respectively.

  The control unit 13 determines the stop position of the ball based on the determined midpoint Q. Specifically, the position of the midpoint Q is set as the stop position. Then, the control unit 13 displays an icon indicating the stop position ("X" in the figure in the figure) at the position on the course layout display corresponding to the obtained stop position, but it may be a variety of other models imitating a ball. Draw). The reason why the midpoint of the virtual line KS formed by a straight line connecting the two intersections A and B is determined as the ball stop position is that the arithmetic processing can be easily performed. Note that the illustrated concentric circles S and virtual lines KS are for explaining the algorithm of the arithmetic processing of the control unit 13, and these concentric circles S and virtual lines KS are not actually displayed on the display device 14.

[Shots after the second shot]
In the case of the second and subsequent shots, the control unit 13 sets the stop position of the ball automatically determined with the previous shot as the current shot position. As shown in FIG. 8, the control unit 13 obtains the estimated flight distance from the swing speed or the ball speed by the estimated flight distance calculation function in the same manner as described above, and the estimated flight distance centered on the hit point (current shot position). Intersection points A1 and B1 between the concentric circle S1 of r1 and both sides (boundary lines with the rough) of the fairway F are obtained, and a midpoint Q1 of a virtual line KS1 connecting the intersection points A1 and B1 is obtained. And the control part 13 determines the stop position of a ball | bowl based on the calculated | required middle point Q1. Here, the position of the midpoint Q1 is determined as the stop position of the ball. And the control part 13 is an icon which shows a stop position in the position on the course layout display corresponding to the calculated | required stop position (In the figure, it is set as "x." Draw.

[Green on treatment]
As shown in FIG. 8, when the concentric circle based on the estimated flight distance intersects the green G as in the concentric circle S3, the control unit 13 determines that the green is on. The determination as to whether or not it intersects with the green G is made based on whether or not there is an intersection between the outer periphery of the green registered in the golf course data storage unit 12 and a concentric circle based on the estimated flight distance. The control unit 13 determines that the green is turned on when the intersection exists.

  When the green is on, the control unit 13 determines the stop position of the ball on the green. That is, the control unit 13 obtains an intersection between the concentric circle S3 and the boundary line of the green G, obtains a midpoint of a virtual line connecting the intersections, and determines a green-on position based on the midpoint. Such a process can be executed by replacing both sides of the fairway in the process of obtaining the intersections of both sides of the fairway (boundary line with the rough) and the concentric circles S and S1 with the boundary line of green.

[Hall-out processing]
The control unit 13 reads the position information of the cup position registered in the golf course data storage unit 12, and obtains the distance (remaining distance) from the green-on position to the cup position. When the obtained remaining distance is equal to or less than a predetermined distance (for example, 1 m), it is regarded as a chip-in, the processing of the hole is finished, and the next hole play is started.

  The golf practice / support apparatus of this embodiment can also estimate the distance of the putt. Therefore, when the remaining distance to the cup exceeds the predetermined distance, the control unit 13 subtracts the estimated flying distance obtained by putting from the remaining distance from the green-on position to the cup. Find the remaining distance after. When the remaining distance after such padding becomes a predetermined distance (for example, 1 m) or less, it is regarded as a cup-in, and the control unit 13 performs display for expressing the cup-in on the display device 14 for several seconds. In addition, when the remaining distance is in the range of 1 to 3 m, the control unit 13 displays “OK” on the display device 14 for several seconds.

  In addition, the processing based on the pad is omitted, and the green-on position is obtained. If the distance between the position and the cup is within a predetermined distance (for example, 1 m), it is determined that the chip has been inserted. May be controlled so that a hole is made by adding one stroke as the number of pads. Further, the number of putts may be added according to the distance to the cup instead of adding one stroke if the green is simply turned on.

[Treatment when both sides of the fairway are not available]
As shown in FIG. 7, for example, the estimated flight distance r4 of the ball hit from the tee ground may be short and may not reach the fairway. Then, the intersection of the concentric circle S4 of the estimated flight distance r4 and both sides of the fairway F cannot be obtained. In such a case, the control unit 13 uses both sides of the hall instead of both sides of the fairway. That is, since the golf course data storage unit 12 also stores positional information for specifying the position of the outer peripheral edge of the hole, the same processing as that on both sides of the fairway described above, that is, the fairway and the rough The position information for specifying the position of the boundary line is replaced with the position information for specifying the position of the outer peripheral edge of the hole.

  That is, the control unit 13 extracts points registered as position information in order to specify the outer peripheral edge of the hole existing in the vicinity of the circumference of the concentric circle S4, and the circumference of the concentric circle S4 from the information indicating the arrangement order of the points. Two consecutive points that cross the line are obtained, and the intersection of the line segment connecting the two points and the concentric circle S4 is obtained. The control unit 13 obtains the intersections A ″ and B ″ by executing such processing on both sides of the hole. Then, the control unit 13 obtains the midpoint Q4 of the virtual line KS ″ connecting the intersections A ″ and B ″, and determines the stop position of the ball based on the obtained midpoint Q. Specifically, The position of the point Q4 is set as the stop position, and the control unit 13 sets an icon indicating the stop position (“X” in the figure, which represents the ball) at the position on the course layout display corresponding to the obtained stop position. And other various things).

  Further, there are cases where the estimated flight distance of the ball hit toward the green is short and the stop position of the ball is between the fairway and the green (see concentric circle S2 in FIG. 8). In such a case, since the intersection between the concentric circle S2 and both sides of the fairway cannot be obtained, the control unit 13 obtains the intersections A2 and B2 between the both sides of the hole and the concentric circle S2, and the virtual connecting the intersections. The stop position of the ball is determined based on the midpoint of the line KS2.

[Determination of Ball Stop Position (Modification 1): Based on Hole Side]
In the above-described embodiment for automatically determining the stop position of the ball, the stop position is determined based on the midpoint Q between the sides A and B of the fairway. However, the present invention is not limited to this. For example, the control unit 13 determines based on the midpoints of the intersections A ′ and B ′ between the both sides of the hole and the concentric circle S. That is, since the golf course data storage unit 12 also stores positional information for specifying the position of the outer peripheral edge of the hole, the same processing as that on both sides of the fairway described above, that is, the fairway and the rough The position information for specifying the position of the boundary line is replaced with the position information for specifying the position of the outer peripheral edge of the hole. That is, even when there is an intersection between both sides of the concentric circle and the fairway, the above-described “processing when the sides of the fairway cannot be used” is executed. In this way, it is sufficient that the stop position of the ball can be determined by the same algorithm regardless of whether or not the intersection of the fairway and the concentric circle exists.

  However, depending on the hole, there is a large forest on the left or right side, and the area on one side of the fairway may be extremely wide. In such a case, if the midpoint between the two sides of the hole is taken, there is a risk that the stop position of the ball may be off the fairway or in some cases in the forest. In this case, it is preferable to provide a function for determining a predetermined position in the fairway as a stop position of the ball. Such a function, for example, finds the midpoint of an imaginary line connecting the intersections with both sides of the hall, and determines whether the midpoint position is within the fairway. In the fairway, the midpoint position is determined as the stop position of the ball. On the other hand, when outside the fairway, a predetermined position in the fairway on the virtual line KS, for example, an intersection with the side of the fairway closer to the midpoint position is obtained, and the stop position of the ball is determined based on that position. To do. When such an intersection does not exist, for example, when it has not reached the fairway, the midpoint of the virtual line is determined as the stop position of the ball.

[Determination of Ball Stop Position (Modification 2)]
In the embodiment and the first modification described above, a virtual line that connects the intersections of the concentric circle whose radius centered on the shot position is the estimated flight distance and both sides of the fairway, green, or course is obtained, and the virtual line The point was taken as the stop position of the ball. This imaginary line is also a chord between two intersecting points on the circumference of a concentric circle. If the position of the midpoint of the imaginary line is the stop position of the ball, it becomes shorter than the estimated flight distance.

  Therefore, the stop position of the ball may be set to a predetermined position on the circumference of the concentric circle. Specifically, the control unit 13 obtains the midpoint of the arc AB when the intersections of both sides of the concentric circle and the fairway are A and B, and determines the position as the stop position of the ball. The midpoint of this arc AB intersects with the radius passing through the midpoint Q from the center P (shot position) of the concentric circle S using, for example, the midpoint Q of the straight virtual line KS connecting the intersections A and B described above. A point on the circumference of the concentric circle S is obtained and set as the stop position of the ball. Thus, it is not limited to what is determined based on the midpoint Q of the virtual line KS, and arithmetic processing for obtaining the midpoint of the arc AB may be performed. By determining the stop position of the ball on the circumference of the concentric circle S in this way, the stop position of the ball comes to the position according to the estimated flight distance, which is preferable in that an accurate simulation can be performed.

  The predetermined position on the circumference of the concentric circle is not limited to the midpoint of the arc between the sides of the fairway, but the arc between the intersections of the concentric circle and the green sides. The position of the green on may be obtained using the midpoint of the ball, or the stop position of the ball may be obtained using the midpoint of the arc between the intersections of the concentric circle and both sides of the hole.

  In the case where the estimated flight distance r2 is short and does not reach the fairway after hitting from the tee ground in FIG. 7, the width of both sides of the hole is longer than the width of the fairway. When the midpoint Q4 of the string A "B" is set to the midpoint Q4 'of the arc A "B", the difference in flight distance becomes large. The simulation can be accurately performed by using the stop position.

  Further, taking the second shot shot in FIG. 8 as an example, when the estimated flight distance is between the fairway and the green, such as the concentric circle of the estimated flight distance is “S2,” the intersection A2 on both sides of the hole. , B2, the midpoint position of the virtual line (string) KS2 is the stop position of the ball, the midpoint position of the virtual line KS2 is fairway even though the estimated flight distance exceeds the fairway. Although there is a contradiction that it falls within the range, if the ball stop position is determined on the circumference of the concentric circle S2 of the estimated flight distance as in this modification, such a contradiction does not occur.

  In particular, if the course layout of the hall is dog-wrecked or the width of the hall is wide and the distance between the two intersections of the concentric circle and the two sides of the hall is long, a virtual line connecting the intersections with a straight line ( Since the stop position of the ball is determined on the (string) and the stop position of the ball is determined on the concentric circle (arc), the difference becomes large.

  Therefore, it is good also as the specification which sets the stop position of a ball | bowl on a concentric circle like this modification, Usually, using the midpoint of the virtual line with easy calculation processing, between two intersections on a concentric circle If the distance exceeds the reference value, it may be set on a concentric circle (the midpoint of the arc between two intersections).

[Ball stop position correction function]
The control unit 13 may have a position correcting function for the automatically determined stop position of the ball. That is, for example, when the touch panel is placed on the display device 14 and the control unit 13 detects that the user has dragged the icon indicating the stop position of the ball, the control unit 13 moves the stop position according to the drag. The movement at this time may be on a virtual line or on a concentric circle. Further, when there is no touch panel, the control unit 13 receives an instruction of a moving direction from a cursor key prepared as the switch 19 and displays an icon indicating a stop position in the instructed moving direction on a virtual line or on a concentric circle. Moving.

[Water hazard treatment]
In the golf course data storage unit 12, position information (boundary lines) for specifying an area such as a water hazard is also registered. Therefore, the control unit 13 determines whether or not the stop position of the ball obtained by the various algorithms described above is within the water hazard. If the stop position is within the water hazard, the predetermined position on the near side of the water hazard is determined as the ball position. The stop position is determined and one stroke is added. The predetermined position on the near side of the water hazard is, for example, the intersection of the straight line passing through the first stop position of the ball in the water hazard and the cup position and the boundary line of the water hazard (opposite to the green). The intersection is determined as the predetermined position.

[Visualization of calculation processing]
In the above-described embodiment, the concentric circle S and the virtual line KS are not drawn, but the icon indicating the stop position is drawn. In addition to the concentric circle S, a function of drawing a virtual line KS may be provided.

[Embodiment using capture route]
The algorithm for automatically determining the stop position of the ball is not limited to the above examples. For example, as shown in FIG. 9, a strategy route RT is registered for each hole, and the ball is determined to stop on the strategy route RT.

  That is, position information for specifying the capture route RT is registered in the golf course data storage unit 12 in association with each hole. The capture route RT is connected from a predetermined position (for example, the center) of the tee ground to the green (cup). The position information for specifying the capture route RT is the same as the position information for specifying the position of the boundary line between the fairway and the rough, and the absolute position of any point on the capture route RT and the position of each point. This is information indicating the arrangement order. By registering position information of many positions on the line indicating the capture route RT, even a complicated curve can be reproduced, and a more accurate capture route can be created.

  As shown in FIG. 9, in the dock-legged course, the capture route RT is specified by a curve or a broken line. When the capture route is bent in this way, the position information for specifying the capture route RT is in addition to a predetermined position in the tee ground and a predetermined position (cup position) in the green, and the inflection point at which the curve is bent. Register the location information of the point. As the number of inflection points to be registered increases, the capture route can be set smoothly and along the course layout. On the other hand, the smaller the number of registrations, the reproduced capture route RT becomes a linear polygonal line and the smooth curve cannot be reproduced, but the memory usage capacity can be reduced.

  In short holes and other holes with a linear course layout, the capture route RT may be specified by a straight line connecting the tee ground and the cup. In the case of such a straight line, the position information for specifying the capture route RT registers at least the absolute position of the two points of the predetermined position in the tee ground and the green (cup). Of course, position information of a plurality of points on a straight line may be registered.

  Since the actual cup position varies depending on the day, it is preferable to set the capture route RT with the center of the green as a virtual cup position. In addition, the capture route RT actually varies depending on the influence of trees and other obstacles planted on the course and the flight distance of the player, but if there is a route recommended / illustrated at a golf course or the like, for example. It is good to use it.

[Stop position determination process]
The actual ball stop position determination process is as follows. The control unit 13 recognizes the club type designated via the club selection switch, obtains an estimated flight distance from the swing speed or the ball speed, and a concentric circle S having an estimated flight distance r centered on the hit point P; An intersection point Q ′ with the capture route RT is obtained, and the position of the intersection point Q ′ is determined as the stop position of the ball. The intersection Q ′ between the concentric circle S and the capture route RT is, for example, two adjacent positions registered on the front side and the back side of the circumference of the concentric circle S from the position information registered for specifying the capture route RT. The position information of one position is acquired, and it is determined by obtaining the intersection of the line connecting the two positions and the circumference of the concentric circle S. Then, an icon indicating the stop position is drawn at a position on the course layout display corresponding to the determined stop position of the ball. After the second shot, the stop position of the ball is obtained in the same procedure and repeated until the hole is out. Other processes can be the same as those described above. By setting the capture route RT in this way, the process of determining the stop position of the ball for each shot can be easily performed.

[User registration process of capture route]
The capture route RT is registered in the golf course data storage unit 12 by data update at the time of shipment or after purchase, but it is preferable to have a function for the user to register. That is, the control unit 13 displays the course layout of the hall to be registered on the display device 14 in accordance with an instruction from the user. The user touches and designates an arbitrary point in the displayed course layout. At this time, the route from the tee ground toward the green is touched in order. The control unit 13 draws a designated point with a circle or other marks and draws a straight line connecting adjacent points. As a result, a capture route made up of broken lines is drawn on the course layout. If the displayed capture route is acceptable, the user presses a confirmation button or the like. When detecting the pressing of the confirmation button, the control unit 13 registers the currently displayed capture route (the point touched by the user) as information on the capture route of the user data.

  Each point that specifies the capture route of the user data may have a function of moving its position in the edit mode, deleting a set point, or newly adding a point. Thereby, a strategy route can be set according to improvement of the user's technical ability and the like. In this way, the user can set an appropriate capture route in accordance with his / her own ball, flight distance, etc., and can perform simulation / practice more suited to actual battle.

  Also, it is desirable to have a function that can edit the capture route registered as standard. That is, when the capture route is reproduced by connecting a plurality of registered points (inflection points), each point can be moved. The edited capture route may be updated by overwriting, or may be stored separately as user data.

  In the embodiment, one capture route is prepared for each hole in the embodiment, but a plurality of capture routes may be set and selected by the user when used. As a plurality of capture routes, for example, “general male”, “female” (capture route from ladies tee), “long distance hitter”, “beginner” (for people with a short flight distance) and the like are available.

  In use, the control unit 13 determines the stop point of the ball based on either the user data capture route or the standard capture route. Which one is used may receive an instruction from the user each time, or when there is user data, the user data may be used with priority.

In each of the above modes, the control unit 13 may have a function of obtaining a meet rate when the ball is actually hit. The meet rate can be obtained based on the head speed and the speed (initial speed) of the launched ball. That is, when the ball can be punched cleanly (meet ratio is high), the head 2a of the golf club 2 pushes out the ball 4 while crushing the ball 4, and the ball 4 receives from the head 2a the repulsive force due to its own elastic restoring force. The ball moment (initial speed) increases due to the inertial moment. On the other hand, when it cannot be punched cleanly (poor hit: meet rate is small), the repulsive force is small, the moment of inertia received from the head 2a is small, and the ball speed is slow. Therefore, the control unit 13
The meet rate is calculated by meet rate = ball speed / head speed.

  The control unit 13 aggregates the meet rate for each club type, obtains an average value, a maximum value, and a minimum value, and records them in the storage device 20 or displays them on the display device 14. By looking at the average value for each club type, users can objectively recognize clubs that are good at meet rates and those that are low at meet rates, which can be used to build practice plans afterwards. . Further, by looking at the maximum value and the minimum value, it is possible to know from the difference between the club type where the meat rate is stable and the club type which is not stable. For club types with a stable meet rate, if the head speed is constant, the flying distance variation is small, but if the meet rate is not stable, the flying distance variation is large even if the head speed is constant. Become. The actual predicted flight distance may be obtained by multiplying the estimated flight distance obtained from the head speed by a coefficient based on the meet rate.

  For this coefficient, the meat rate may be simply used as it is, or a table of multiplication rates for the meat rates may be prepared, and the multiplication rates for the meet rates may be used. The multiplication rate increases as the meet rate increases.

  In the golf practice mode, as described above, by outputting the meet rate to the display device 14 as a measurement result, the user can recognize the pros and cons of each club type. Meet rate can be displayed simply as text, or a bar graph or graphic such as concentric circles showing the average, maximum, and minimum values so that the range of variation can be understood intuitively for each club type. Anyway.

  In addition, when operating in the golf navigation mode, the estimated flying distance (average value) and variation range (maximum / minimum) when the club type is selected from the current position are calculated and displayed, and the predicted flying distance considering the meat rate is displayed. The distance may be obtained and displayed.

  Furthermore, in the training mode using the actual course layout of the golf course, processing that takes into account the meat rate becomes more realistic. That is, when the meat rate is low, the estimated flight distance decreases, but often does not fly straight (slice / hook) due to failure to hit. Therefore, as shown in FIG. 10, when the meet rate is equal to or less than the reference value, the control unit 13 determines a position shifted by a predetermined angle θ from the capture route RT as the stop position of the ball. That is, the control unit 13 obtains an intersection point Q ″ between the concentric circle S ′ whose estimated flying distance is shortened with the decrease in the meet rate and the correction line rotated by the angle θ from the capture route RT, and uses it to stop the ball By using the angle, the amount of deviation from the capture route RT is small if the flight distance is short, but if the flight distance is long, the amount of deviation from the capture route RT is also large. It will be.

  The angle θ may be a fixed value, or may be increased as the meat rate is lower and bends more greatly (deviation from the capture route). Then, the direction of shifting may be determined randomly each time, or may be shifted in a predetermined direction. When the meet rate is equal to or less than the reference value, the user is either left / right. It is also possible to make an inquiry about whether to shift, wait for an instruction from the user, and shift in the indicated direction. The predetermined direction may be always shifted to one side as a device, or may be designated by the user. If the user makes a certain decision whether to turn to the right or left when making a miss shot, the latter method is used to approximate the actual situation.

  The next shot is processed with the stop position of the ball shifted from the capture route as the shot position. That is, when the estimated flight distance is obtained based on a swing or the like, the intersection point between the concentric circle centered on the shifted ball stop position and the capture route RT is obtained, and is set as the next ball stop position.

  In addition, when the vehicle deviates from the capture route RT as described above, or the flight distance is too short or too long, the stop position of the ball may deviate from the fairway such as rough. In this case, if the ball is actually hit from such a position, it is easy to make a miss shot. Therefore, when shooting from other than the fairway, the flight distance is shortened by multiplying the estimated flight distance by a predetermined coefficient. If it has a function of shifting by a predetermined angle θ from the capture route RT at random, it will be more interesting.

  Each result stored in the storage device 14 in each mode can be transferred to a personal computer and stored in the storage device of the personal computer, and a large amount of data can be stored and managed over a long period of time. Further, by displaying the data recorded in such a manner on the screen of the personal computer, it becomes easier to see and more detailed analysis can be performed by taking more complicated arithmetic processing and statistical processing.

Further, each result stored in the storage device 14 in each mode is also registered in the server as user-specific information, and after accessing and acquiring the server when used later, such as the average flight distance, each process described above is performed.
