Description

The present invention relates to an apparatus and a program for calculating an altitude difference.

A golf support device that provides various information to a golf player while playing a golf course is known. For example, Patent Document 1 describes that information such as the distance from the current position to the green is displayed on the screen.

Japanese Unexamined Patent Publication No. 2013-039423

For golf players, the distance from the current location to a destination such as the green is useful information, but the altitude difference between the current location and the destination is equally useful. However, there has been no model of golf support devices that can display information on altitude differences.

The reason is that it is difficult to obtain the height difference from the current position to the destination with an accuracy that can be used as a reference for playing (for example, an accuracy of ± 1 m) in a small portable device that can be used on a golf course. It can be mentioned. For example, as a method of obtaining an altitude difference, a method of calculating from atmospheric pressure, a method of measuring altitude by a GPS function, a method of obtaining from digital elevation data (mesh data) and latitude / longitude, and the like can be considered. The purpose cannot be achieved.

That is, since the atmospheric pressure fluctuates depending on the weather conditions, it is not possible to obtain the altitude of the current position from the atmospheric pressure alone. Therefore, even if the altitude of the destination point is known, the altitude difference between the current point and the destination point cannot be obtained. In addition, the accuracy of altitude measurement by the GPS function is low, and it is not possible to obtain the altitude difference with an error that can be used as a reference for play. In addition, the digital elevation data has a large data capacity, and it is not realistic to store the digital elevation data for many golf courses in a portable device. Furthermore, the digital elevation data has the problem that the mesh is coarse (even the most accurate data provided by the Geographical Survey Institute has a mesh mesh of 5 meters), and the altitude between the meshes is calculated by interpolation. There is no way, but the golf course has many steep terrain, and in places where the altitude difference between meshes is very large (such as depressions), the altitude obtained by interpolation does not match the actual altitude, and the player's confidence in the display is impaired. It will be lost.

The present application discloses inventions addressing all or part of the above problems or other problems. The present application discloses not only those for calculating altitude difference as reference information for golf play, but also various devices and programs such as devices and programs for calculating altitude difference that can be used in various fields.

The present application discloses, for example, the inventions described in the following configuration examples.

<Structure example 1>
It is a portable device having a function of notifying the altitude difference between the current point and the destination point in the reference area and the location area including the destination point corresponding to the reference area.
A storage means for storing reference area information indicating the position of the reference area and reference altitude difference information for calculating the reference altitude difference which is the altitude difference between the reference area and the destination point.
The position acquisition means for acquiring the position information of the current position and
Atmospheric pressure measuring means for measuring barometric pressure and
A reference pressure holding means that holds the reference pressure, which is the pressure measured by the pressure measuring means when the current position is within the reference region, and
Altitude difference notification means that calculates and notifies the altitude difference between the current point and the destination point based on the current atmospheric pressure, which is the atmospheric pressure measured by the atmospheric pressure measuring means at the present time, the reference pressure, and the reference altitude difference information. A device characterized by having.

According to such a configuration, the user can know the altitude difference between the current point and the destination point in the spatial area, and can be useful for grasping the positional relationship between the current point and the destination point. Knowing the difference in altitude between your current location and your destination is useful in golf, orienteering, skiing, snowboarding, mountaineering, etc.

The spatial area is the area containing the reference area and the destination point. The reference area is an area within the location area, and the destination point is a point away from the reference area within the location area. If the locational area is an area of a route in which a person moves from a reference area to a destination, an area on such a route, or an area including such a route, the user can move from the current position to the destination. It is good because you can know the height difference of. The spatial area may include one reference area or may include a plurality of reference areas. The spatial area may include one destination or may include a plurality of destinations. The reference area may correspond to a plurality of destination points. When there are a plurality of reference areas, each reference area may correspond to a plurality of destination points. The destination may correspond to a plurality of reference areas. When there are a plurality of destination points, each destination point may correspond to a plurality of reference areas.

The reference area information may be, for example, data of coordinates defining the boundary of the reference area, but it is further preferable to use data of the coordinates of the center of the reference area and the radius because the amount of data stored in the storage means can be reduced. The reference area information may be, for example, point information or, for example, latitude / longitude information. For example, it may be a group of information on a plurality of latitudes and longitudes, but it may be information on a single latitude and longitude. For example, the point of the latitude and longitude may be used as a reference area, but a predetermined area including the point of latitude and longitude may be used as a reference area. The predetermined area may have a radius of, for example, 10 meters centered on the point of latitude and longitude. When there are a plurality of reference areas, the storage means may store the position information of the plurality of reference areas in association with the target point.

The reference altitude difference information may be the altitude of the reference area and the destination point, but it is further preferable to use the altitude difference between the reference area and the destination point because the amount of data stored in the storage means can be reduced.

In this configuration, since the altitude difference is calculated using the atmospheric pressure measured by the barometric pressure measuring means, the amount of data stored in the storage means can be reduced as compared with the case of calculating using the numerical elevation data stored in the storage means. Therefore, it is good because the altitude difference can be calculated by faithfully reflecting the undulations in a narrower range. Further, even if the reference area or the destination point is changed, it is sufficient to change the position information and the reference altitude difference information of the reference area of the storage means, so that the data can be easily updated. When there are a plurality of reference areas and / or destination points, it is preferable to store the reference altitude difference information in the storage means in association with each combination of the reference area and the destination point.

なお、上記式（１）、（２）における「101325（Pa）」は、海面気圧の標準値であるが、上記式（３）の高度差を求めることが目的であるため、上記標準値を使用しても問題はない。（（式３）で海面気圧の値が標高値算出に与える影響が差し引かれるので、（３）の高度差の算出値に海面気圧の値は殆ど影響しない。） The altitude difference between the current point and the destination point may be obtained, for example, by subtracting the altitude difference between the reference area and the current point from the reference altitude difference. The altitude difference between the reference region and the current position may be calculated, for example, from the pressure difference between the reference pressure and the current pressure by using a known mathematical formula showing the relationship between the pressure difference and the altitude difference. Such formulas are known. For example, the current atmospheric pressure may be CP and the reference atmospheric pressure may be TP, and the calculation may be performed by the following equations (1) to (3).

The "101325 (Pa)" in the above equations (1) and (2) is a standard value of the sea surface pressure, but since the purpose is to obtain the altitude difference of the above equation (3), the above standard value is used. There is no problem using it. (Since the influence of the sea level pressure value on the elevation value calculation is subtracted in (Equation 3), the sea level pressure value has almost no effect on the calculated altitude difference in (3).)

The barometric pressure measuring means may be, for example, a barometric pressure sensor. The position acquisition means may be, for example, a GPS receiver. The notification by the notification means may be a notification by voice, but may be a notification by visual display.

<Structure example 2>
It is characterized in that the relationship between the reference region and the target point is set so that the time normally required for moving from the reference region to the target region is a time during which it can be considered that the atmospheric pressure change due to climate change does not normally occur. Device.

In this configuration, the present inventor pays attention to the fact that the atmospheric pressure does not change so much that it greatly affects the altitude difference calculation if it is a relatively short time, and it usually takes time to move from the reference region to the target region. , During the movement from the reference area to the destination because the relationship between the reference area and the target area is set so that the time that the atmospheric pressure change due to the weather change can be considered not to occur normally (for example, within 10 minutes to 30 minutes). , It is good because the altitude difference between the current point and the destination point can be calculated accurately. The time during which it can be considered that the atmospheric pressure change due to the weather change does not normally occur is preferably the time during which the atmospheric pressure change does not occur except for extreme weather conditions such as a typhoon. If the atmospheric pressure change does not occur, for example, the atmospheric pressure change may be such that the influence of the atmospheric pressure change on the calculated value is smaller than the error allowed in light of the purpose of use of the device. The relationship between the reference region and the target point may be a positional relationship, and the positional relationship may be determined in consideration of the speed at which the moving means from the reference region to the target region can be taken. For example, if the means of transportation is walking, the distance should be within tens of minutes on foot. In this configuration, even when the destination point cannot be visually recognized from the current position due to an obstacle (for example, a hill or a forest), the user may know the altitude difference between the current point and the destination point.

<Structure example 3>
The reference region is a spatial region that can be regarded as having no altitude difference, and is characterized in that it is a region that serves as a start position within the spatial region when the user carries the device and aims at the target point. Equipment to do.

In this configuration example, the user only moves from the start position in the location area toward the target point, and then can know the altitude difference between the current position and the target point in the location area. Further, since it can be considered that there is no altitude difference in the reference region, it is sufficient that the altitude difference between the current position and the destination point can be accurately calculated regardless of the pressure measured at any point in the reference region. When it can be considered that there is no altitude difference, for example, it is preferable that the altitude difference is smaller than the error allowed in light of the purpose of use of the device.

<Structure example 4>
The spatial region includes the reference region and a plurality of sets of destination points corresponding to the reference region.
The storage means stores the reference area information and the reference altitude difference information for each of the sets.
The device further comprises a set selection means for selecting the set.
The altitude difference notification means includes the current atmospheric pressure, the reference pressure measured by the atmospheric pressure measuring means when the current position is in the reference region of the set selected by the set selection means, and the reference for the set. A device characterized by calculating the altitude difference between the current position and the destination point based on the altitude difference information.

With this configuration, it is possible to calculate and notify the altitude difference between the current position and the destination point for the group selected from the plurality of groups. As the group selection means, for example, the group may be selected based on the position information of the current position. For example, it is advisable to select a set that includes a reference region closest to the current position.

<Structure example 5>
The spatial area comprises a plurality of compartmentalized areas.
Each of the compartment areas is a device comprising the set.

With this configuration, the spatial area is a relatively large area, and it takes a long time to move from one point to another, and the calculation of the altitude difference is greatly affected during that time. Even if changes in weather conditions can occur, the location area is divided into multiple compartments, and within each compartment, a short time (for example, within 10 minutes) that does not cause changes in weather conditions By setting the reference area and the destination so that the reference area can be moved to the destination within 30 minutes), the altitude difference between the current point and the destination can be accurately calculated in each section area. .. For example, if the location area is a mountaineering course and it takes a long time (for example, several hours) to move from the mountaineering entrance to the summit, the mountaineering course may be divided into multiple compartments that can be moved in a relatively short time. It is good to divide it.

<Structure example 6>
The altitude difference notification means is a device for notifying the altitude difference between the current point and the target point included in the one section area when the current point is in one section area.

In this configuration example, it may be possible to notify the altitude difference between the current point and the destination point in each section area.

<Structure example 7>
A device characterized in that the locational area is an area within a golf course and the destination point is a point on the green.

In this configuration, it is sufficient to provide the player with useful information for golf play, such as the difference in altitude between the current position and the point on the green at the golf course. Further, in golf, the time to play a one-hole golf course is relatively short (usually about 10 to 20 minutes), and during that time, it is larger than the accuracy (for example, ± 1 m) required as reference information for playing. Since the weather conditions rarely change to the extent that the effect is applied to the altitude difference calculation, if the location area is a one-hole golf course in the golf course, the current position and the destination point are sufficiently accurate as reference information for play. It is good because the altitude difference can be provided to the player. In Configuration Example 7 quoting Configuration Example 5, assuming that the location area is a golf course with a plurality of holes (for example, a golf course from the 1st hole to the 9th hole) and the division area is a golf course with 1 hole, each hole. It is good to know the altitude difference between the current position and the point on the green at the golf course of. The point on the green may be, for example, the center of gravity of the green. The calculation and notification of the altitude difference between the reference area and the current position in this configuration may be performed, for example, at intervals of 5 seconds or less. This is because on a golf course, the altitude difference may change significantly when the player walks for about 5 seconds.

<Configuration Example 8>
A device characterized in that the reference region is a region including a tee ground.

In this configuration, the player always passes through the tee ground according to the rules of golf, so by setting the reference area to the area including the tee ground, it is possible to measure the reference pressure more reliably. Since the altitude difference is often small in the area including the tee ground, it is possible to accurately calculate the altitude difference between the current point and the destination point.

<Structure example 9>
The storage means further stores reference point information indicating the position of the reference point located in the reference area.
The reference altitude difference is the altitude difference between the reference point and the destination point.
The reference pressure holding means is a device characterized in that the pressure measured by the pressure measuring means is held as the reference pressure when the current point is closest to the reference point.

In this configuration, the closer to the reference point, the smaller the altitude difference from the reference point is likely to be. Therefore, the reference altitude difference is used as the altitude difference between the reference point and the destination point, and the current position is the closest to the reference point as the reference pressure. By using the atmospheric pressure measured at that time, the altitude difference between the current position and the destination point can be calculated with higher accuracy.

<Structure example 10>
The locational region comprises the plurality of said reference regions.
The storage means stores the reference area information and the reference altitude difference information about the reference area for each of the plurality of reference areas.
When the current point passes through a plurality of the reference areas in the process of moving to the destination.
The altitude difference notification means is an apparatus characterized in that the altitude difference between the current point and the destination point is calculated by using the reference altitude difference information for the reference region to which the current point is closest.

In this configuration, the reference altitude difference information for a plurality of reference regions is stored, and the altitude difference between the current location and the destination point is calculated using the reference altitude difference information for the reference region closest to the current location, so that it is more accurate. It is good because it is more likely that the current altitude difference can be calculated.

<Structure example 11>
The device characterized in that the reference region has a geometric shape.

In this configuration, since the reference region has a geometric shape, the reference region can be easily set. The geometric shape may be circular, square, or the like. For example, by looking at an aerial photograph or by actually measuring with GPS, the outer shape of the area to be included in the reference area (for example, tee ground) is determined, and the geometric shape including the outer shape is used as the reference area. good. For example, in the case of a circle, one point (for example, the center of gravity) in the outer shape may be selected as a reference point, and a circle drawn around the reference point so as to include the outer shape may be set as a reference region. The inclusion may be, for example, circumscribed. For example, the reference region may be defined by data showing a geometric shape. For example, it may be vector data showing a geometric shape, a mathematical formula showing a geometric curve, or coefficient data thereof, but it may be simply center coordinate data of a circle, radius data, or the like.

<Structure example 12>
The device for notifying the altitude difference is provided with a function of notifying the reference altitude difference instead of the altitude difference between the current point and the destination when the current point is within the reference area.

In this configuration, when the current position is within the reference region, a more reliable reference altitude difference may be notified. For example, if the reference area is an area that includes the tee ground, the player has the most room to play when the player is on the tee ground, so the player can see a reliable altitude difference in a room. .. When the current position is outside the reference region, it is preferable to have a function of calculating and notifying the altitude difference between the current point and the destination point based on the current pressure, the reference pressure, and the reference altitude difference information.

<Structure example 13>
The altitude difference notification means is a device characterized in that the reference altitude difference and the altitude difference between the current point and the destination point are notified in the same notification mode.

In this configuration, it is not necessary to give the user a sense of discomfort or complexity due to the notification mode changing depending on whether the altitude difference displayed by the altitude difference notification means is the reference altitude difference or the altitude difference between the current point and the destination point. The same notification mode means, for example, that the display position, font, display size, display color, and the like when displaying the altitude difference on the display screen are the same.

<Structure example 14>
The storage means further stores the position information of the destination point.
The device for notifying the altitude difference when the distance between the current point and the destination becomes less than or equal to a certain value.

When the user comes close to the destination, it becomes easier for the user to visually measure the altitude difference between the current point and the destination, while the closer the current point is to the destination, the longer the time from the measurement point of the reference pressure may be. It is highly probable that the calculation error of the altitude difference due to climate change during that period will also increase. In this configuration, the altitude difference is not notified when the distance between the current point and the destination is less than a certain value, so the possibility of giving the user the impression that the notified altitude difference does not match the visual measurement is reduced. It's good because it can be done. In the range of 30 m, it is easy for a normal player to visually measure the altitude difference, so the constant value is preferably 30 m.

<Structure example 15>
Further having a history storage means for storing the history that the current position has entered the reference area,
The altitude difference notification means is a device characterized in that the altitude difference is not notified when there is no history that the current position has entered the reference area.

Since the altitude difference between the current location and the destination cannot be calculated when the current location is not yet in the reference area, it is possible to notify the user that the altitude difference has not been calculated by not notifying the altitude difference. It's good because it can be done. The non-notification mode in this configuration may be different from the non-notification mode in Configuration Example 12. For example, when the altitude difference is notified by the altitude difference notification means by displaying a digital numerical value, the non-notification of the configuration example 12 is performed in such a manner that the numerical value is not displayed (the display position of each digit of the numerical value is left blank). The non-notification of the configuration example 13 may be performed by displaying a bar at the display position of each digit of the number as in "----".

<Structure example 16>
The locational area comprises a plurality of said destinations.
The altitude difference notification means is a device characterized by calculating and notifying the altitude difference between the current point and the destination point for each of the plurality of destination points.

In this configuration, the altitude difference between the current location and the destination for multiple destinations is displayed on one screen, so the user does not have to operate the device, and the current location and purpose for each destination are displayed. It is good because you can know the altitude difference of the point. For example, when a location area may have two destination points on the left and right, such as a green on a golf course, and which destination point on the left or right can be used depends on the location area, the user can use the location. It is not necessary to select the target destination point for each area. The notification of the altitude difference for each of the plurality of destination points may be displayed on one screen, for example.

<Structure example 17>
The storage means further stores the position information of the destination point.
A device further comprising a distance notifying means for notifying the distance between the current point and the destination point.

In this configuration, since the distance and altitude difference between the current point and the destination point are notified, the user may be able to more easily grasp the positional relationship between the current point and the destination point.

<Structure example 18>
A program for realizing the function of the device according to any one of the configuration examples 1 to 17 in a computer.

The configurations described in the above-mentioned configuration examples and the like may be combined and configured within a range that does not cause a contradiction. Further, it is preferable to construct a new configuration example by arbitrarily combining the components described in each configuration example and the like within a range that does not cause a contradiction.

The golf support device 1 is provided with a display unit 3 on the upper surface of a flat, substantially rectangular case 2. The display unit 3 constitutes a touch panel. If the backlight is built in and the backlight of the screen is turned on when a button is operated or the screen is touched, the visibility is improved. A charging lamp 8 is arranged on the rear side of the upper surface of the case 2.

A power button 4 is arranged on the side surface of the case 2. The power button 4 is used not only as a power ON / OFF button, but also as a point registration button and a touch panel operation lock / unlock switching button. Specifically, when the control unit 11 recognizes that the power button 4 has been pressed and held (for example, for 2 seconds or longer) while the power is off, the power is turned on, and the control unit 11 displays a predetermined main menu screen on the display unit 3. indicate.

Further, when the power button 4 is operated for a short time while the power is on, the control unit 11 executes the function of registering a point. The function of point registration will be described later. When the power button 4 is pressed and held while the power is on, the control unit 11 alternately switches the lock / unlock of the touch panel. That is, if it is currently in the locked state, it is released and the operation by the touch panel is enabled, and if it is currently in the unlocked state, it is switched to the locked state and the operation by the touch panel is invalidated. The current state is notified by an icon drawn at a predetermined position on the display unit 3.

Further, a terminal cover 7 that can be opened and closed is attached to the rear surface of the case 2, and when the terminal cover 7 is opened as shown in FIG. 1 (b), the microUSB terminal 9 is exposed. It can be charged by connecting an AC adapter to the microUSB terminal 9.

Inside the case 2, a control unit 11, a storage unit 12, a GPS reception unit 13, a barometric pressure sensor 14, a geomagnetic sensor 15, an attitude sensor 16, and a battery 17 connected to the control unit 11 are provided.

The control unit 11 includes a microcomputer including a CPU, ROM, RAM, flash memory, various peripheral circuits, interfaces, and the like. When the power is turned on, the control unit 11 is supplied with power from the battery 17 and starts operation. The control unit 11 executes various processes described later by expanding and executing the OS and the application program recorded in the flash memory or the like on the RAM, and realizes various functions. A display unit 3, a power button 4, and the like are connected to the control unit 11, and the control unit 11 receives an operation signal such as the power button 4 and controls the display on the display unit 3.

The storage unit 12 is composed of an internal memory and a recording medium such as a detachable external recording medium (micro SD memory card or the like). The storage unit 12 has a golf course data storage unit 12a and a processing data storage unit 12b.

The golf course data storage unit 12a stores golf course data, which is data relating to a plurality of golf courses at one or a plurality of golf courses in Japan and overseas. In this embodiment, a golf course for one hole is called a "golf course", and a group of golf courses (for example, a golf course from the 1st hole to the 9th hole and a 10th hole to the 18th hole). The golf course up to) is called a "course". A golf course (or area including it), a course (or area including it), a golf course (or area including it) may correspond to the "locational range" of the claims.

Here, in order to explain the golf course data, a general golf course 20 will be described with reference to FIG.

As shown in the figure, the golf course 20 includes a tee ground 21 and a green 22. The figure shows a golf course 20 with two tee grounds 21 and two greens 22. Generally, the number of tee grounds in a one-hole golf course 20 is one to three. Generally, there may be only one green on the golf course 20 of one hole, or two greens on the left and right. When there are a plurality of tee grounds 21, which tee ground 21 is used is generally determined by the designation of the golf course, the agreement between the players, and the like. When there are two greens 22 on the left and right, which green 22 to use is generally determined by the designation of the golf course. The golf course 20 may have one or more obstacles 24, such as a bunker or a pond. The golf course 20 may include fairways, roughs and the like. Between one golf course 20 and the golf courses before and after it (for the golf course 20 of the first hole, between the clubhouse and the like), there is a movement route 23 such as a cart road.

The golf course data includes layout images and hole data for each golf course 20 at each golf course.

The layout image is image data for displaying the layout (shape) of each golf course 20 on the display unit 3.

Hall data includes division latitude / longitude, object data, tee data and automatic movement point data.

The division latitude / longitude is the latitude / longitude of the four corners of the division area 25 set for each golf course 20. The division area 25 is an area including an area where the player can move in playing on the golf course 20. In the present embodiment, the shape of the compartment area 25 is a quadrangle. The compartment area 25 is set as a sufficiently large area that includes the golf course 20.

The object data is data indicating the latitude and longitude of various objects in the golf course 20. Specifically, the object is from the destination point 28 set on the green 22, the edge on the side of the green 22 near the tee ground 21 (hereinafter referred to as "front green edge"), and the tee ground 21 of the green 22. It includes an edge on the distant side (hereinafter referred to as "green edge on the back side"), an obstacle 24, and the like. The destination point 28 is set near the center of the green 22. More specifically, the center of gravity of the polygon shape when a polygon shape substantially matching the green 22 is drawn by looking at an aerial photograph, a course design drawing, or the like is set as the target point 28. For a golf course 20 having two greens 22 on the left and right, the latitude and longitude of the destination points 28, the green edge on the front side and the green edge on the back side of each of the left and right greens 22 are stored as object data. (Hereinafter, the destination point 28 of the green 22 on the left is referred to as "the destination point 28 on the left", and the destination point 28 on the right green 22 is referred to as "the destination point 28 on the right".) When there are a plurality of obstacles 24 The latitude and longitude of each obstacle 24 are stored as object data.

The tee data is data relating to the reference region 26 set for each tee ground 21 in the golf course 20.

The reference region 26 is set as a circular region including the tee ground 21. Specifically, the outer shape of the tee ground 21 (or the area where the tee ground 21 may be set) is determined by looking at an aerial photograph, a course design drawing, etc., and drawn so as to circumscribe the outer shape. The circle is the reference region 26. When there are a plurality of tee grounds 21, a reference area 26 is set for each tee ground 21, and tee data is set for each reference area 26. The figure shows a case where a plurality of reference regions 26 do not have overlapping regions, but a plurality of reference regions 26 may have overlapping regions.

The tee data includes tee coordinates, tee radius and reference altitude difference between left and right. The tee coordinates are the latitude and longitude of the reference point 27, which is the center of the reference region 26. The tee radius is the radius of the reference region 26. The reference region 26 is defined by the tee coordinates and the tee radius. By defining the reference area 26 with the tee coordinates and the tee radius, the amount of data stored in the storage unit 12 can be reduced.

The left reference altitude difference is the altitude difference between the reference point 27 and the left destination point 28, and the right reference altitude difference is the altitude difference between the reference point 27 and the right destination point 28. The left and right reference altitude difference is calculated from the altitude value of the reference point 27 and the altitude value of the left and right destination points 28. These elevation values are the data of the grid-shaped elevation points maintained by the Geographical Survey Institute. Of the basic map information digital elevation model elevation points, the four elevations closest to the target point (reference point 27 or destination point 28). It is calculated using the value obtained by smoothing the value of the point. For the golf course 20 having only one green 22, only the left reference altitude difference is set.

The automatic movement point data is data relating to the movement area 29 for determining the movement of the player from the golf course (or clubhouse) immediately before to the golf course 20. The movement area 29 is a circular area set near the movement route 23 on the front side of the golf course 20. The movement area 29 is set to an appropriate size and position at which the movement of the player to the golf course 20 can be reliably determined. When it is necessary to determine the movement of the player to the golf course 20, such as when there are a plurality of movement routes 23, a plurality of movement areas 29 are set. The automatic moving point data includes the latitude / longitude and the radius (automatic moving point radius) of the center point of the moving area 29.

In addition to the above, the golf course data is used for searching / selecting a golf course or course, displaying information in the display unit 3, etc., so that information about the golf course (golf course ID, category, golf course name (kanji, frigana, English, abbreviation) ), Country code, phone number, postal code, prefecture ID (region overseas), prefecture name (region name overseas), time zone, address, golf course section maximum latitude / longitude, golf course section minimum latitude / longitude, etc.) And information about the course (course ID, course name (kanji, frigana, English, abbreviation), number of hole numbers added, next course ID, etc.), other information about the golf course (hole number, number of PARs, etc.) include. Further, the golf course data includes the altitudes of the reference point 27, objects, and the like as surplus data.

The processing data storage unit 12b stores a numerical value used in the altitude difference calculation display processing described later, a calculated numerical value, and the like.

The GPS receiving unit 13 determines the latitude and longitude of the current position based on the signal from the GPS hygiene and provides it to the control unit 11. The barometric pressure sensor 14 measures the current barometric pressure and provides it to the control unit 11. The geomagnetic sensor 15 measures the geomagnetism to obtain the direction and angle at which the golf support device 1 is facing and provides the control unit 11. The posture sensor 16 is composed of an acceleration sensor and a gyro sensor, and provides information indicating whether the golf support device 1 is in the vertical orientation or the horizontal orientation to the control unit 11.

Hereinafter, the function of the control unit 11 will be described based on a specific display screen. When the control unit 11 determines that the latitude / longitude of the current position determined by the GPS receiving unit 13 has passed through the moving area 29, the control unit 11 reads out the hole data of the golf course 20 including the free moving point data for the moving area 29. , The golf navigation screen 30 displaying the layout image of the golf course 20 is displayed on the display unit 3. FIG. 4 shows an example of a golf navigation screen 30 when the golf course 20 has two greens 22 on the left and right (when the hole data includes object data for the two destination points 28 on the left and right).

In the center of the golf navigation screen 30, a layout image of the golf course 20 currently being played is displayed so that the green is on top. In addition, the own icon 31 is displayed at the position corresponding to the location (latitude and longitude of the current position acquired from the GPS receiver 13) of the drawn layout image, and corresponds to the pin position (cup position) on the green. The flag icon 32 is displayed at the place. As a result, the player can know the course layout, the direction of the green 22, and the like. In addition, the distance 33 from the current position to an obstacle such as a pond or a bunker on the golf course 20 is displayed, and further, the equidistant concentric line 34 centered on the own icon 31 and the position on the concentric line 34 from the current position. Distance 35 to is displayed. As a result, the player can know the distance to the obstacle on the golf course 20 and the approximate distance to any place on the golf course 20. By knowing this information, the user can confirm how to capture each hole even if it is the first course. The distance 33 to the obstacle can be displayed / hidden by operating a button displayed at the bottom of the golf navigation screen 30.

The control unit 11 further detects the direction in which the device is facing based on the output of the geomagnetic sensor 15, and draws the direction as a direction indicating line (dotted line) 36 consisting of an arrow and a dotted line on the golf navigation screen 30. do. The starting point of the direction indicator line 36 is the current position (own icon 31). As a result, when the user changes the direction while holding the device, the direction indicator line 36 on the display screen turns accordingly, and the direction indicator line 36 is aligned with the green or the place to be hit. By doing so, you can confirm that there is a target point ahead of you. Therefore, even if the visibility is poor due to fog or the like, or even if there are trees or obstacles, the direction can be accurately known.

Further, the control unit 11 displays the green data display units 37L and R on the left and right sides of the golf navigation screen 30, and displays the distance and altitude difference to the object on the left green 22 on the left green data display unit 37L. Then, the green data display unit 37R on the right displays the distance and altitude difference to the object on the green 22 on the right.

More specifically, the control unit 11 displays three distances D1 to D3 and an altitude difference ED in the upper and lower four stages in the green data display units 37L and R. The first-stage distance D1 is the distance between the current position and the green edge on the back side, the second-stage distance D2 is the distance between the current position and the destination point 28, and the fourth-stage distance D3 is the current position. This is the distance of the green edge on the front side. The control unit 11 calculates and displays these distances from the latitude / longitude of the current position and the latitude / longitude of the destination point 28 or the like stored in the object data. The altitude difference ED in the third stage is the altitude difference between the current point and the destination point 28. The method of calculating the altitude difference ED will be described later. The units of the distances D1 to D3 and the altitude difference ED displayed on the green data display units 37L and R are meters or yards, and the control unit 11 can be used by the user to operate a button displayed at the bottom of the golf navigation screen 30. Switch between metric display and yard display accordingly. The control unit 11 calculates the distances D1 to D3 and the altitude difference ED only when the current position determined by the GPS receiving unit 13 is within the partition area 25, and the current position cannot be determined. When the current position is outside the division area 25, "----" is displayed as the distances D1 to D3 and the altitude difference ED.

In this way, since the distances D1 to D3 and the altitude difference ED for both the left and right greens 22 are displayed, the player can operate the device even if the left or right green 22 is used for each hole. You can know the distances D1 to D3 and the altitude difference ED for the green 22 you want to know without performing.

Further, in the control unit 11, the distance D1 between the current position and the green edge on the back side is green, the distance D2 between the current point and the destination point 28 is white, and the distance D3 between the current position and the green edge on the front side is red. The altitude difference ED is displayed in the same color as the distance D2 between the current point and the destination point 28. As a result, the player intuitively understands that the distances D1 to D3 are the distances to different points, and the distance D2 and the altitude difference ED are the distances and altitude differences between the same points (current point and destination point 28). It will be easier to understand.

5 and 6 show the golf navigation screens 30a and 30b displayed by the control unit 11 when the player flicks the display unit 3 while the golf navigation screen 30 of FIG. 4 is displayed. show. FIG. 5 is a golf navigation screen 30a displayed when a left flick operation is performed. Only the left green data display unit 37L is displayed on the left side of the screen, and a hazard showing the distance to the obstacle 24 is displayed on the right side of the screen. The distance display unit 38 is displayed. FIG. 6 is a golf navigation screen 30b displayed when a right flick operation is performed. Only the right green data display unit 37R is displayed on the right side of the screen, and a hazard showing the distance to the obstacle 24 is displayed on the left side of the screen. The distance display unit 38 is displayed. In this way, the player displays both the left and right green data display units 37L and R (golf navigation screen 30), or the left and right green data display units 37L and R and the hazard distance display unit, depending on his preference. It is possible to select whether to display 38 (golf navigation screens 30a, 30b). When there is only one green 22 on the golf course 20 (when the hole data does not include the object data for the destination point 28 on the right), the control unit 11 always displays the golf navigation screen 30a similar to that in FIG. However, even if there is a flick operation, the golf navigation screens 30 and 30b according to the embodiments shown in FIGS. 4 and 6 are not displayed. In this specification, when it is not necessary to distinguish each golf navigation screen 30, 30a, 30b, it is simply referred to as "golf navigation screen 30".

Further, as shown in FIG. 4, the control unit 11 displays a hole icon 40 indicating information on the golf course 20 such as a hole number and the number of pars at the upper part of the golf navigation screen 30. The illustrated hole icon 40 indicates that the currently displayed golf course 20 is the 8th hole and the number of pars is “4”. When the hole icon 40 is touch-operated, the control unit 11 changes the golf course 20 displayed on the golf navigation screen 30. For example, assuming that the golf course 20 on the 8th hole is displayed as shown in the figure, each time the hole icon 40 is touched, the control unit 11 sequentially displays the 9th hole and the 10th hole on the display unit 3. The golf navigation screen 30 for the golf course 20 is displayed.

On the golf navigation screen 30, it is possible to display the distance between three points by touching any point on the layout image. That is, when the control unit 11 detects a touch operation on the layout image, the control unit 11 displays the icon 41 at the touched position and from the current position to the touched point as shown in FIG. The distance 42 and the distance 43 from the touched point to the destination point 28 are calculated and displayed. As a result, the player can know the distance between the second and third shots and can formulate an accurate course strategy.

Further, the player can register a point on the golf course 20 based on a switch operation or the like while the golf navigation screen 30 is displayed. That is, when the power button 4 is operated briefly, the control unit 11 acquires the latitude and longitude of the current position from the GPS receiving unit 13 and stores it in the storage unit 12 together with the time at that time. The point registration can be used, for example, to record the point where the ball is actually hit. When the point registered point exists in the layout image displayed on the golf navigation screen 30, the control unit 11 draws the point registration icon 44 at the corresponding position as shown in FIG.

When it is detected by the signal from the posture sensor 16 that the golf support device 1 is turned sideways while the golf navigation screen 30 is displayed, the control unit 11 displays the display unit 3 in FIG. 9. Switch to the horizontal golf navigation screen 50 shown. On the horizontal golf navigation screen 50, the vicinity of the green 22 in the layout image is enlarged and displayed. As a result, the player can see the detailed situation near the green 22 by a simple operation of changing the direction of the device. On the horizontal golf navigation screen 50, the control unit 11 has a left green data display unit 51L that displays a distance D2 from the current position to the left destination point 28 and a distance D3 to the front green edge of the left green 22. While displaying the right green data display unit 51R displaying the distance D2 from the point to the destination point 28 on the right and the distance D3 to the green edge on the front side of the green 22 on the right, the distance to the green edge on the back side and the current position And the height difference of the destination point 28 is not displayed. This simplifies the screen and makes it easier for the player to understand what is displayed. When it is detected by the signal from the posture sensor 16 that the golf support device 1 is oriented vertically while the horizontal golf navigation screen 50 is displayed, the control unit 11 displays the display of the display unit 3 as golf. Switch to the navigation screen 30.

FIG. 10 shows a flow of calculation display processing of the altitude difference ED executed by the control unit 11 when the current position of the golf support device 1 is located in the division area 25 of the golf course 20. The control unit 11 executes this calculation display process using the hole data read from the golf course data storage unit 12a when displaying the golf navigation screen 30. As described above, when the golf course 20 has two greens 22 on the left and right, the altitude difference ED is calculated and displayed for both the left and right greens 22 on the left and right green data display units 37L and R. Here, the process related to the calculation display of the altitude difference ED (altitude difference ED displayed on the left green data display unit 37L) for the left green 22 will be described. However, in the explanation, the process related to the calculation display of the altitude difference ED for the green 22 on the left may also be mentioned.

The control unit 11 is conditioned on the condition that the control unit 11 determines that the current position has passed the moving area 29 based on the latitude / longitude of the current position determined by the GPS receiving unit 13 and the automatic moving point data of the golf course 20. The calculation display process is started.

When the calculation display process starts, in step S1, the control unit 11 sets the minimum tee distance TLm used as a process parameter to the initial value. As this initial value, a numerical value (for example, 256 m) sufficiently larger than the tee radius of all the reference regions 26 stored in the golf course data is used.

In the following step S2, the control unit 11 identifies the reference area 26 of the reference point 27 closest to the current position from the latitude and longitude of the current position positioned by the GPS receiving unit 13 and the tee coordinates of each reference area 26 (hereinafter,). The reference area 26 specified in step S2 is referred to as the “most recent tee area NT”), and the distance TL between the current position and the reference point 27 of the latest tee area NT is calculated.

In the following step S3, the control unit 11 determines whether or not the current position is within the nearest tee region NT, that is, the distance TL is the tee radius of the nearest tee region NT (the tee radius of the latest tee region NT is "tee radius Tr". It is written as.) It is judged whether it is less than.

If the determination in step S3 is affirmative (Yes), the control unit 11 determines in step S4 whether the distance TL is less than the minimum tee distance TLm.

If the determination in step S4 is affirmative (Yes), the control unit 11 updates the value of the minimum tee distance TLm to the distance TL in step S5. In this way, when step S5 is executed, the minimum tee distance TLm is smaller than the initial value. Therefore, in step S8 described later, the player determines whether the minimum tee distance TLm matches the initial value. It is possible to determine whether or not there is a history of entering the reference area 26 even once since the golf course 20 was first entered.

In step S6, the control unit 11 sets the left and right reference altitude differences (the left reference altitude difference is "left reference altitude difference LTED" and the right reference altitude difference is "right reference altitude difference RTED" for the nearest tee region NT. (Notation) is extracted from the hall data, and the left and right reference altitude differences LTED and RTED and the reference barometric pressure TP, which is the measured value of the barometric pressure sensor 14 at that time, are stored in the processing data storage unit 12b. In step S6, the left and right reference altitude differences LTED and RTED for the reference region 26 of the reference point 27 to which the current point is closest to each other in the process of the player moving in the golf course 20 and the reference pressure TP at the time of the closest approach are obtained. It will be held in the processing data storage unit 12b. If the determination in step S4 is negative (No), the control unit 11 skips steps S5 and S6.

In step S7, the control unit 11 displays the left reference altitude difference LTED stored in the processing data storage unit 12b as the altitude difference ED of the green data display unit 37L. As a result, when the golf support device 1 is in the reference area 26, the altitude difference between the reference point 27 and the destination point 28 calculated in advance based on the elevation value of the base map information digital elevation model elevation point is displayed on the display unit 3. Will be done. Therefore, the player can see the accurate altitude difference between the reference point 27 and the destination point 28 on the left at a timing when he / she can afford to confirm the altitude difference, such as waiting for another player's tee shot.

If the judgment in step S3 is negative (No), that is, if the current position is not within the reference region 26, the process proceeds to step S8.

In step S8, the control unit 11 determines whether the minimum tee distance TLm is equal to the initial value. If the determination is affirmative (Yes), that is, if there is no history of entry into the reference region 26, the control unit 11 does not calculate the altitude difference ED, and in step S9, the green data display unit. A bar (“－－－”) is displayed as an altitude difference ED of 37L. As a result, the player can know that the altitude difference ED between the current point and the destination point 28 has not been measured.

If the judgment in step S8 is negative (No), that is, if the minimum tee distance TLm is smaller than the initial value, the control unit 11 determines the distance DLG from the current position to the destination point 28 on the left side in step S11. It is calculated and it is determined whether or not the distance DLG is less than a certain value GN. If the determination is affirmative (Yes), a blank (“”) is displayed as the altitude difference ED of the green data display unit 37L in step S12. As a result, the altitude difference ED is hidden in the range from the green to less than a certain value GN, which is considered to make it easier for the player to measure the altitude difference, and the altitude difference that can be caused when the altitude difference ED that does not match the player's eye measurement is displayed. It is possible to prevent a decrease in the player's confidence in the display of the ED. For the constant value GN in step S11, 30 m is used when the green data display units 37L and R are displayed in meters, and 30 yards is used when the green data display units 37L and R are displayed in meters. Regardless of whether it is displayed in meters or in yards, if 30m is used as a constant value GN, for example, 30m is about 33 yards. ) Will be switched to, which may give the user a sense of discomfort, and this is prevented.

If the determination in step S11 is negative (No), in step S13, the control unit 11 measures the reference pressure TP and the left reference altitude difference LTED held in the processing data storage unit 12b, and the pressure sensor 14 at that time. The calculated value CED of the altitude difference between the current position and the destination point 28 on the left is obtained based on the current atmospheric pressure CP, which is a value, and is displayed as the altitude difference ED of the green data display unit 37L.

As a specific calculation method, the control unit 11 calculates the altitude difference ΔH by the following equations (1) to (3), and subtracts the altitude difference ΔH from the left reference altitude difference LTED to obtain the calculated value CED. Ask.

In golf, the time required to play one golf course 20 is about 10 to 15 minutes, and it is considered that the influence of changes in weather conditions within that time on the current atmospheric pressure CP is extremely small. Therefore, step S13. In, the altitude difference between the current point and the destination point 28 can be accurately calculated and displayed, and the player can refer to the displayed altitude difference ED for play.

After the execution of steps S7, S10, S12 and S13, the control unit 11 waits for about 1 second, and then shifts the process to step S2. As a result, the processes of steps S2 to S13 are repeatedly executed, and the display of the altitude difference ED is updated every second or so.

Although the preferred embodiment has been described above, the shapes, dimensions, materials, functions, operation modes, control modes, control parameters, operation modes, etc. of the devices, systems and programs or their elements, members, etc. in the above embodiments are examples. These are described as, and these can be changed.

For example, in the above embodiment, the case of the golf support device 1 used on the golf course has been described as an example, but the purpose of using the device of the present invention is not limited to golf, and the current position is used in orienteering, skiing, snowboarding, mountain climbing, and the like. It is also possible to use a device that notifies the altitude difference of the destination point.

Further, in the above embodiment, the case where the reference area 26 is a region including the tee ground has been described, but the reference region may be a region that coincides with the tee ground or may be a region other than the tee ground. Further, the size of the reference region is not limited, and for example, the area of the reference region may be infinitely small. For example, the reference area may be one point having no area.

Further, in the above embodiment, the case where the destination point 28 is near the center of the green 22 (to be exact, the center of gravity of the polygon drawn so as to substantially match the outer shape of the green 22) has been described. It can also be another point, for example, another point within the green 22 or a point outside the green 22. The destination point does not have to be one point having no area, and may be a set of a plurality of points, or the destination point may have an area having a certain area.

Further, the destination point may be configured to be configurable by the user's operation. For example, in many golf courses, the position of the cup changes from day to day. Therefore, it is more convenient to allow the user to set the position of the cup of the day as the destination because the altitude difference between the current position and the position of the cup of the day is displayed. The destination point may be set, for example, so that the control unit 11 sets the latitude and longitude of the position touched by the user on the golf navigation screen 30 or the horizontal golf navigation screen 50 as the destination point. When the destination point is configured to be configurable by the user's operation, for example, the elevation value of the base map information digital elevation model elevation point in the green 22 (or near the green 22) is stored in the storage unit 12 as hall data. The control unit 11 calculates the elevation value of the destination point set by the user by using the value obtained by smoothing the elevation value of the four basic map information digital elevation model elevation points closest to the destination point set by the user. Then, it is advisable to calculate the reference altitude difference using the calculated elevation value.

The method of calculating the altitude difference between the current point and the destination point, the type and format of the data used for the calculation, and the like are not limited to the embodiment, and any other appropriate method, type, and format can be used.

Further, in the above embodiment, the case where the control unit 11 stores the latitude and longitude of the current position when the point registration operation is performed is stored in the storage unit 12, but for example, the point registration operation is performed. Occasionally, the control unit 11 displays the latitude and longitude of the current point at that time, and the altitude difference between the current point and the destination point by the display calculation process at that time (in steps S7 and S13, the left and right green data display units 37L and R are displayed. The displayed altitude difference ED) may be recorded in the storage unit 12. The data recorded in this way may be configured to be displayable on the display unit 3, or may be configured to be output to a personal computer or the like via the microUSB terminal 9 or the like so that the data can be displayed on the personal computer. The data should be displayed by calculating the distance and altitude difference between the two points registered at the points, so that the player can display the flight distance and altitude difference for each shot (altitude difference between the points where the ball flew). ) Can be known. Since the flight distance of the ball is affected by the altitude difference (whether it is a launch shot or a downhill shot, etc.), it is useful for the player to know the altitude difference together with the flight distance.

Further, although the golf support device 1 shown in FIG. 1 is suitable for handheld carrying, the golf support device 1 can also be a device that can be worn on a wrist or the like in the form of a wristband or the like. When it can be worn on the wrist or the like, it is possible to detect the swing of the player by an acceleration sensor or the like and configure the control unit to automatically register the points where the swing is detected.

The base built into the golf support device 1 may be provided with a water-repellent coat, so that the golf support device 1 can be safely used even when the golf support device 1 gets wet due to unexpected heavy rain or the like.
