Description

Apparatus and Method for measuring real distance

The present invention relates to a method for measuring a real distance and an apparatus for measuring a real distance, and more particularly, by measuring a real distance between a current position and a target point to a user using a GPS system and a tilt measuring module. The present invention relates to a real distance measuring method and a real distance measuring device to be transmitted.

The present invention can be most easily applied to the method for measuring the actual distance of the golf course and the actual distance to the golf club and the actual distance measuring device for measuring the actual distance to the target point of the golf course, but is not limited thereto, and various leisure activities other than golf And other uses.

Using a conventional GPS system (Global Positioning System), a distance measuring device that tells the user the distance between the current position and the target point is used, in particular using a variety of GPS systems that tell the golfer the distance to the green of the golf course Distance measuring devices are widely used.

Such a distance measuring apparatus using a conventional GPS system is a position coordinate value (latitude and longitude coordinates or X, Y coordinate values) of the golfer received by the GPS system and the position coordinate values (latitude and longitude coordinates) of the green of the golf course previously stored. Alternatively, the method simply calculates the linear distance on the horizontal plane by using the X and Y coordinate values.

Therefore, even when there is an inclination angle at the position of the golfer and the position of the green, there is a technical limitation that only the straight distance is known and the actual distance is not known. That is, when there is an inclination angle at the position of the golfer and the position of the green, the actual distance is not measured but the straight distance on the horizontal plane is measured and the distance information transmitted to the golfer has a large distance error. This distance error is, for example, when the angle of inclination between the golfer's position and the green position is about 20 degrees and the actual distance is 500m, the error of the distance is calculated as 500-500cos (20), and the error exceeds 30m.

In addition, at a distance close to the green, for example, a distance of about 30m, due to the inherent positional error of the GPS value in addition to the error due to the tilt, that is, an error of about 10m radius, the error rate between the actual distance and the measurement distance is It becomes bigger. Accordingly, the distance measuring apparatus using the conventional GPS system can not provide a reliable distance value in golf play.

BRIEF DESCRIPTION OF THE DRAWINGS It is a block diagram which shows an example of the real distance measuring apparatus which concerns on this invention.

The apparatus for measuring a real distance of the present invention includes an operation control module 30 for performing various operations and controls; A GPS receiving module 10 capable of receiving a location coordinate from a GPS satellite and determining a user's location and time; A tilt measurement module 20 for measuring and outputting a tilt in a horizontal plane of the measuring device; A user input unit 50 for allowing a user to select according to various operation modes; An output unit 60 for displaying the operation distance and the state of the device; And a memory 40 that stores various information about a specific terrain such as height information of a user, height information of an object installed vertically at a specific location, and horizontal position coordinate data of a specific location of a specific terrain.

When the present invention is applied to a real distance measuring device for golf, the user is a golfer, and the specific terrain is a golf course.

The GPS receiving module 10 receives a signal from a GPS satellite to determine a user's location and stores the location coordinates or outputs the calculated coordinates to the operation control module.

The user input unit 50 is a component that allows a user to select various functions of the device, and one or more of various input methods such as button input, key input, or touch may be used. In addition, in the present invention, when the distance between the user and the target point is far, the long distance mode for measuring the actual distance, when the distance between the user and the target point is close, a near-mode mode capable of more accurate actual distance measurement, 0 points for correcting the user's height information One mode of the adjustment mode is configured to be selected by the user input unit 50.

In addition, the output unit 60 is a configuration capable of displaying the operation distance and the state of the device, and is primarily a display unit, but is not limited thereto. Other components capable of displaying the operation distance and the state of the device may be used therein.

The inclination measurement module 20 preferably includes at least one of an acceleration sensor and a gyro sensor. The inclination measurement module 20 measures an inclination in a horizontal plane of the measurement device and outputs the inclination in the calculation control module 30.

The acceleration sensor measures the inclination as shown in FIG. 8A, and as shown in FIG. 8B, the acceleration sensor inevitably occurs when the central axis of the sensor moves, so as to correct the error as shown in FIG. 8B. In combination with the gyro sensor to configure the tilt measurement module, it is possible to increase the accuracy of the measured tilt angle. On the other hand, it is possible to measure the tilt only by the gyro sensor, but in the case of commercialized gyro sensor, since the error of the output value is severe when temperature changes, it is preferable to configure the tilt measurement module together with the acceleration sensor.

The memory 40 is configured according to height information of a user, height information of an object (eg, a flag pole, etc.) installed vertically at a specific position, and horizontal position coordinate data of a specific position of a specific terrain, for example, according to a hole course of a golf course. Various information such as GIS data is stored.

The operation control module 30 performs an operation using information stored in the memory 40 and / or a signal output from the GPS reception module 10 according to the signal output from the user input unit 50. The actual distance is output to the output unit 60, and the operation of controlling various operations of the device is performed. In addition, the operation control module 30 may also perform zero point adjustment for correcting the user's height information by the tilt angle value measured by the tilt measurement module 20.

Hereinafter, with reference to the accompanying drawings, it will be described in detail with reference to the actual distance measuring device and method for golf which is a preferred embodiment of the present invention.

As shown in the flowchart of FIG. 2, in the user input unit, a user (golfer) may select one of a remote mode, a near mode, and a zero adjustment mode (S10). For example, it may be a configuration in which the remote mode is executed. The distance mode and the near mode selection are within 30m of the target point within 30m of the target point in consideration of the point where the GPS position error is 10-20m and the ability to recognize the target point visually. It is preferable to select the near mode, and the selection of the near mode may be selected by a user (golf), or may be set to automatically switch to the near mode in the apparatus by the primary distance measurement.

(1) FIG. 3 is a view for explaining an embodiment of the remote mode of the present invention, and a method for calculating a real distance from a position of a user (golf) to a specific position of a specific terrain using a GPS receiving module will be described. It is for.

In the remote mode of the present embodiment, when the distance between the current position of the golfer and a specific position (target point) of the golf course is far, the golfer's current horizontal position coordinate is obtained by using the GPS receiving module, and the tilt angle measured by the tilt measuring module This mode is used to measure the actual distance together.

When the remote mode is executed (S20), the GPS receiving module 10 receives the GPS signal and outputs the current horizontal position coordinates of the golfer to the operation control module (S21).

In addition, the inclination measurement module 20 measures the inclination of the device by measuring the inclination angle with respect to the horizontal plane of the device which is inclined as the golfer aims the specific position of the golf course through the device (the scale unit, if equipped with a scale unit). The angle value is output to the operation control module (S22).

In the memory 40, horizontal position coordinate data of a specific position of a golf course is stored.

As shown in FIG. 3, the arithmetic control module 30 calls the horizontal position coordinate data (DB coordinate) of the specific position from the memory 40 and outputs the horizontal position coordinates of the golfer outputted from the GPS receiver module. GPS line) and the DB coordinate to calculate a straight line distance (D ') from the golfer's position to a specific position of the golf course, using the tilt angle value (a) of the device output from the tilt measuring module, Equation (1) calculates and outputs the actual distance D from the position of the golfer to the specific position of the golf course (S23).

Actual distance (D) = linear distance (D ') / sin (a) Equation (1)

For example, if the straight line distance is 100 m and the slope of the golf course is 20 degrees (70 degrees of tilt angle), the actual distance is about 106 m, and the error between the straight distance and the actual distance is about 6 m.

According to the present invention, it is possible to provide the golfer with the correct thread distance without such a distance error, thereby enabling accurate hitting.

It is for explaining a method of calculating the actual distance from the position of the user (golf) to a specific position of a specific terrain using the height information. FIG. 6 illustrates a thread from a position of a user (golfer) to a specific position of a specific terrain using height information stored in a memory unit and an object standing perpendicular to a specific position, that is, a height of a flagpole erected in a hole in the case of a golf course. It is for explaining the method of calculating the distance.

The height information includes one or more of the user's (golf's) sitting key information and the sun key information. Depending on the embodiment, only one of the user's (golf's) sitting key information and the sun key information is required, or the user's (golf's) sitting information is required. Both key information and line key information are required. In the case of a vertically erected object, that is, a golf course, the height of the flagpole erected in the hole may be measured and stored in advance or modified by a user (golfer).

In the near mode, a distance between a golfer's current position and a specific position (target point) of the golf course is close, and the actual distance is measured using the inclination angle measured by the inclination measurement module without using the GPS receiver module. .

The short range mode is based on the GPS error of 10 to 20m and the ability to recognize the target point visually. It is preferable to select a mode, and the selection of the near mode may be selected by a user (golf) or may be set to automatically switch to the near mode by the apparatus by the first distance measurement.

(a) When the short range mode is executed A first embodiment of the real distance measuring method will be described with reference to FIGS. 4A and 4B.

In the first embodiment of the actual distance measuring method, both the sitting key information and the line key information of the user (golf) are required. This is a method of measuring a real distance using a tilt angle value measured by a golfer standing at one point, that is, the same point as the tilt angle value measured at the current position.

As shown in FIG. 4A, the inclination measurement module 20 is configured such that the inclination angle value and the user (golf) of the device inclined as the user (golf) sits at the ball position and aims a specific position (Hole) of a specific terrain through the device. ) At the same position (Ball position) and outputs the inclination angle value of the device inclined by aiming a specific position (Hole) of the specific terrain through the device (S31 and S32).

The operation control module 30 calls the height information including the sitting key information and the line key information of the golfer stored in the memory 40, and uses the two tilt angle values and the height information to perform the following equation (2). -1) and (2-2) to calculate the actual distance from the golfer's position (Ball) to a specific position (Hole) of the particular terrain (S33).

In the case of a vertically erected object, that is, a golf course, the height of the flagpole erected in the hole may be measured and stored in advance or modified by a user (golfer).

As shown in FIGS. 6A and 6B, the tilt measurement module is used to tilt the device as the user (golf) is standing (or sitting) at the current Ball position and aims at the lowest point of the flagpole at a particular position (Hole). The tilt angle value and the tilt angle value of the device inclined as the user (golf) aims the top of the flagpole through the device are output (S31 and S32).

The memory 40 stores one or more pieces of height information among the sitting key information and the line key information of the golfer (user) and the flagpole height information.

The operation control module 30 calls the golfer's extension information stored in the memory 40 and uses the two inclination angle values and the one or more extension information, and the following equations (4-1) and (4- Through 2) to calculate the actual distance from the golfer's position (Ball) to the flagpole (Hole) (S33).
