(1) Sensor part and input part

The sensor unit 100 may be configured to include an IMU (Inertial Measurement Unit, an inertial measurement device, and an inertial measurement device). It is composed of a combination of sensors (geomagnetic fields) and measures the speed, direction, gravity, and acceleration of a moving object to measure free movement in a three-dimensional space.

It is widely used in the fields of flying objects, ships, robots, and ICT, including aircraft.

Specifically, the acceleration sensor of the IMU measures acceleration and gravitational acceleration due to the movement of the sensor (moving inertia), the geomagnetic sensor measures the direction of the magnetic field to measure the direction of gravity and azimuth, and the gyro sensor measures the rotational inertia of the sensor. Measure.

When the user carries or wears such a sensor unit 100 (sensor), it is possible to collect necessary data by walking around the putting line 10 formed between the ball position 11 and the hole cup position 12. have.

The input unit 400 may be implemented by a button formed on a display (touch screen, etc.) of a user terminal, a wired/wireless receiver, a GPS receiver, etc., and serves to receive information for performing various auxiliary and correction functions to be described later. .

(2) Operation part

The calculation unit calculates 3D posture information by data fusion of the information measured by the above-described sensor unit 100, calculates 3D relative coordinates from 3D posture information and acceleration information, and calculates 3D relative coordinates. From this, the ball position 11, the hole cup position 12, the distance, and the inclination are calculated, and the target distance and the target direction of the putting line 10 are calculated from this.

Specifically, when data of a geomagnetic sensor and a gyro sensor are combined using a data fusion technique, 3D orientation information of the sensor unit 100 may be extracted.

In addition, by excluding the gravitational acceleration component from the acceleration sensor data based on the posture information and integrating twice for each coordinate axis, three-dimensional relative coordinates from the starting point can be obtained.

The calculation unit may be implemented by a dedicated application installed on a user terminal (mobile phone, clock, etc.), which processes information received from the sensor unit 100 to generate 3D coordinates, among which the image/ By filtering only the lowest point of the footstep where the downward direction is changed, 3D coordinates of each landing point (the point where the footstep landed) based on the starting point can be obtained, from which the 3D coordinates of the green area measured by the user. Dimensional shape information can be obtained (Fig. 2).

In addition, if the user's 3D attitude information at each landing point is additionally utilized, the normal vector of the green surface can be obtained, and by using this, the area between landing points without data (intervals of 3D relative coordinates) is interpolated. By doing so, the accuracy of the three-dimensional shape information of the green can be improved.

(3) output

The output unit outputs a target distance and a target direction of the putting line 10 so that the user can recognize it, which can be implemented by a monitor or speaker of a user terminal (mobile phone, watch, small speaker, etc.).

Hereinafter, a specific embodiment utilizing the basic technical idea of the golf putting line measuring apparatus according to the present invention will be described.

The sensor unit 100 can collect the above data even if the user carries it in a pocket or wears it on the waist or ankle, but when it is attached to the user's shoe 20, it is possible to collect the most accurate data. One)

To this end, it is preferable that the sensor unit 100 is provided with an attachment portion (ring, lace, Velcro tape, etc.) for attaching to the user's shoe 20.

In the case of attaching to the waist or ankle, it is preferable that such an attachment part is formed.

Even if the sensor unit 100 is attached to only one shoe 20, information can be collected. However, if it is attached to both shoes 20, more information can be collected, so that accurate target distance and target direction can be calculated. I can.

The sensor unit 100 may be equipped with a Bluetooth communication module, a battery, etc. to communicate with a user terminal (an operation unit, an output unit).

When the sensor unit 100 is attached to the user's shoe 20, a certain degree of inclination occurs with respect to the plane (the bottom surface of the shoe), which is when the sensor unit 100 is attached, the user Each time you wear 20), it changes.

Therefore, in order for the operation unit to recognize that the sensor unit 100 in a state that is obliquely attached to the shoe 20 worn by the user has a basic inclination (0°), the user can move the sensor unit 100 on a flat surface before rounding. It is preferable to set the basic inclination (0°) of the sensor unit 100 based on information measured by wearing (carrying) and walking.

Thereafter, the operation unit recognizes that the sensor unit 100 attached in an inclined state has a basic inclination (0°), and measures the inclination of the green based on this.

This can be implemented by pressing the'start basic slope setting' button of the user terminal, walking a predetermined time or a predetermined distance, and then pressing the'basic slope setting complete' button.

Since the putting line 10 is formed in the area between the ball position 11 and the hole cup position 12, the putting line measuring device must first recognize these positions, the correct ball position 11 and the hole cup position 12. Since the user cannot land on the vehicle, an input method taking this into account is required.

To this end, in the case of the ball position 11, a specific signal at a point separated by a preset set distance (eg, 10 cm) in a direction opposite to the direction toward the hole cup position 12 (the putting line direction) from the ball position 11 When is input, a position limiting a set distance from that point (a point 10 cm closer to the hole cup position direction than the signal input position) can be calculated as the ball position 11.

Here, the specific signal is a method of pressing a button on the display of the user terminal, the movement of the sensor unit 100 (e.g., a quick clacking alternately between the left and right feet, keeping the left and right feet aligned for a certain period of time, etc.) It can be implemented by a predefined method or the like.

Even in the case of the hole cup position 12, a specific signal is generated at a point separated by a preset distance (eg, 10 cm) from the hole cup position 12 in a direction opposite to the direction toward the ball position 11 (the putting line direction). When input, a position limiting a set distance from that point (a point 10 cm closer to the ball position direction than the position at which the signal is input) can be calculated as the hole cup position 12.

As described above, on the assumption that the ball position 11 and the hole cup position 12 are input and calculated, the operator walks from the ball position 11 to the hole cup position 12 through one side of the putting line 10. A, after reaching the ball position 11 through the other side of the putting line 10 from the hole cup position 12 again, the ball position 11, the hole cup position 12, the distance, and the slope from the information collected in the process Can be calculated.

This provides information (three-dimensional shape information) obtained while the sensor unit 100 moves both sides of the putting line 10, so that a more accurate target distance and a target direction can be calculated.

If the green slope changes rapidly, by stepping along both sides of the curved line that is expected to be closer to the putting line 10 than the straight line between the ball position 11 and the hole cup position 12. , It is possible to prevent the case where the putting line deviates from the measured area.

As the input unit 400 on the display of the user terminal, a starting point ball position input button 401 inputted at the ball position 11 as a measurement starting point; A hole cup position input button 402 inputted at the hole cup position 12; The end point ball position input button 403, which is input again at the ball position 11, which is the measurement end point; etc., can be formed (Fig. 6).

In this case, the user presses the starting point ball position input button 401 at a point separated from the ball position 11 by the above set distance, and walks to the hole cup position 12 through one side of the putting line 10 to position the hole cup. After pressing the hole cup position input button 402 at the point separated by the set distance from (12), it reaches the ball position (11) through the other side of the putting line (10) and is separated by the set distance from the ball position (11). It is possible to clarify the start and end of information input by pressing the end point ball position input button 403 at the point.

The obtained relative three-dimensional coordinates can be processed and displayed on the output unit 200 (display of the user terminal, etc.) in a form that facilitates recognition of the green height, such as in the form of a contour map. It is possible to easily determine the putting line as if playing in a golf simulator (screen golf) (Fig. 6).

The input unit 400 is a contour information input unit for receiving the contour information of the golf course green previously produced by a separate application or the like; In the case of including a GPS location information input unit receiving the user's GPS location information; the calculation unit checks the corresponding position of the putting line 10 on the golf course green based on the contour line information and the GPS location information, and the putting line 10 The target distance and target direction of can be corrected.

In the case of simulating the movement of the ball by combining the 3D green shape calculated by the above 3D relative coordinates with the physics engine, the target direction of the putting line (for example, three cups to the right) can be presented to the user (Fig. 6).

The target distance of the putting line is determined by the distance and inclination between the ball position 11 and the hole cup position 12, which is a distance in a plane (Distance: 4.0m) to the output unit 200 (display of the user terminal, etc.), It can be displayed in a manner such as elevation: + 0.2m, calculated target distance (6m), etc. (Fig. 6)

Even on a golf course green with the same slope, the putting line (the degree of bending the ball) varies depending on the speed of the green.

When the green speed input part for inputting speed information (for example, 2.9) of the green of the golf course is formed as the input part 400 on the display of the user terminal, the operation unit targets the putting line 10 based on the input speed information of the green. Distance and target direction can be corrected.

In other words, if the speed of the green is fast, the degree of bending of the ball increases, so the target direction is calculated in a direction further away from the hole cup, and if the speed of the green is slow, the degree of bending of the ball decreases. It can be computed in a direction closer to.

Since the above is only described with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as well known, should not be limited to the above embodiments and should not be interpreted, It will be said that both the technical idea and the technical idea together with the fundamental are included in the scope of the present invention.
