Abstract
An aligning apparatus of a golf destination line is provided. The aligning apparatus aligns a putter face of a golf putter with a destination line connecting a golf ball and a destination. A rotation angle between the destination line and the putter face and an acceptance angle are set in a variance setting unit, and the acceptance angle is an acceptable error range of the rotation angle. A 3-axis magnetic resistance sensor measures a magnetic field strength applied to the golf putter, and a 3-axis accelerometer measures an acceleration applied to the golf putter. A processor calculates a tilt angle of the 3-axis magnetic resistance sensor from the measured acceleration, and compensates the measured magnetic field strength with the tilt angle to calculate an azimuth of the putter face of the golf putter. An output unit outputs a reporting signal when a difference between the azimuth and an aligning azimuth determined by the rotation angle is within a range of the acceptance angle.

As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive. Like reference numerals designate like elements throughout the specification.
- In the specification, unless explicitly described to the contrary, the word “comprise/include” and variations such as “comprises/includes” and “comprising/including” will be understood to imply the inclusion of stated elements but not the exclusion of any other elements. In addition, in the specification, “a destination line” means a virtual linear line between a position where a golf ball is located and a destination for the golf ball.
- Now, an aligning apparatus of a golf destination line and a golf putter according to exemplary embodiments of the present invention will be described with reference to the drawings.
- First, an aligning apparatus of a golf destination line according to a first exemplary embodiment of the present invention will be described with reference to
FIG. 1 toFIG. 4 . The aligning apparatus according to the first exemplary embodiment of the present invention is applied to a golf putter 1 (FIG. 2 ), and it is assumed that a reference line for aligning is parallel to a surface of aputter face 1 e (FIG. 2 ). -
FIG. 1 is a schematic block diagram of the golf destination line aligning apparatus according to the first exemplary embodiment of the present invention, andFIG. 2 shows a golf putter in which the aligning apparatus ofFIG. 1 is installed. - As shown in
FIG. 1 , thealigning apparatus 100 according to the first exemplary embodiment of the present invention includes avariation setting unit 10, aninput unit 20, a 3-axismagnetic resistance sensor 30, a 3-axis accelerometer 40, aprocessor 50, anoutput unit 60, and aninterface 70. Referring toFIG. 2 , a golf putter 1 includes ashaft 1 a, agrip 1 b of theshaft 1 a, ahead 1 c, aneck 1d connecting theshaft 1 a and the head, and a putter that is a putting part of thehead 1 c. Thealigning apparatus 100 according to the first exemplary embodiment of the present invention may be inserted into a folder (not shown) that is installed in theshaft 1 a, theneck 1d, or thehead 1 c of the golf putter 1. - Referring to
FIG. 1 again, thevariation setting unit 10 sets a rotation angle and an acceptance angle based on the reference line and the destination line, and the rotation angle and the acceptance angle may be set in thevariation setting unit 10 by the user. The rotation angle is a value for setting an angle variance between the reference line and the destination line, and in a normal state, the angle between the reference line and the destination line is maintained at the rotation angle. The acceptance angle is an acceptable error angle of the rotation angle, and in a normal state, the reference line moves within a range corresponding to the sum of the rotation angle and the acceptance angle with respect to the destination line. That is, the sum of the rotation angle and a sighted azimuth, which is sighted at the time of putting, is an aligning azimuth. For example, when the reference line, i.e., the surface of theputter face 1 e (FIG. 2 ), is sighted to be parallel to the destination line, the rotation angle may be set to 90°, and the acceptance angle may be set to ±0.5°. - The
input unit 20 receives a start signal from the user after the user sights the reference line and the destination line. The 3-axismagnetic resistance sensor 30 includes three resistance sensors that are respectively disposed to the X axis, Y axis, and Z axis of a three-dimensional Cartesian coordinate system, and measures a 3-axis magnetic field strength of the putter 1 when the putter 1 is rotated. The 3-axis accelerometer 40 includes three accelerometers that are respectively disposed to the X axis, the Y axis, and the Z axis of the three-dimensional Cartesian coordinate system, and measures a 3-axis acceleration of the putter 1 when the putter 1 is rotated. Theprocessor 50 determines a tilt angle of the 3-axismagnetic resistance sensor 30 by using a 3-axis gravity acceleration measured in the 3-axis accelerometer 40, and corrects the 3-axis magnetic field strength measured in the 3-axismagnetic resistance sensor 30 based on the determined tilt angle so as to determine an azimuth of the earth. Theprocessor 50 compares the determined azimuth with the aligning azimuth, and outputs a reporting signal through theoutput unit 60 when the difference between the determined azimuth and the aligning azimuth is within the range of the acceptance angle. - The
aligning apparatus 100 transmits signal from/to thevariation setting unit 10, theinput unit 20, the 3-axismagnetic resistance sensor 30, the 3-axis accelerometer 40, and theoutput unit 60 through theinterface 70 to/from theprocessor 50. In addition, thealigning apparatus 100 may include a memory (not shown) storing a program such as the processing routine of theprocessor 50 and a power supplying unit for supplying power to theseelements processor 50, theinterface 70, and the memory may be formed by a microcontroller, a digital signal processor, etc. - Next, an operation of the aligning apparatus of the golf destination line according to the first exemplary embodiment of the present invention will be described with reference to
FIG. 3 ,FIG. 4 , andFIG. 5 . -
FIG. 3 shows a state in which the putter face is sighted to be parallel to the destination line,FIG. 4 shows a state in which the putter face is aligned to be perpendicular to the destination line, andFIG. 5 is a schematic flowchart showing the operation of the aligning apparatus of the golf destination line according to the first exemplary embodiment of the present invention. - Referring to
FIG. 4 , theprocessor 50 receives a start signal from the user through theinput unit 20 at step S410 after thedestination line 3 connecting thegolf ball 2 and the destination is sighted to be parallel to the reference line, which is theputter face 1 e, as shown inFIG. 3 . Then, theprocessor 50 reads the rotation angle and the acceptance angle from thevariation setting unit 10 at step S420. The rotation angle and the acceptance angle have been set in thevariation setting unit 10 by the user. Basically, the rotation angle may be set to +90°, and the acceptance angle may be set to ±0.5°. - Next, the
processor 50 reads the magnetic field strengths HX, HY, and HZ of the respective axes X, Y, and Z measured in the 3-axismagnetic resistance sensor 30 and the accelerations AX, AY, and AZ of the respective axes X, Y, and Z measured in the 3-axis accelerometer 40 at step S430. Theprocessor 50 calculates a resultant vector A of the accelerations applied to the putter 1 as expressed in Equation 1, and compares the resultant vector A of the accelerations with 1[g] in accordance with the effect of acceleration due to gravity at step S440. Here, ‘g’ is a unit of acceleration due to gravity. -
A=√{square root over (A X 2 +A Y 2 +A Z 2)} (Equation 1) - The
processor 50 repeats the step S430 when the magnitude of the resultant vector A of the accelerations is not 1[g]. Theprocessor 50 calculates a pitch angle φ and a roll angle θ, which are the tilt angle of the 3-axismagnetic resistance sensor 30, as expressed inEquation 2, at step S450 when the magnitude of the resultant vector A of the accelerations is 1[g]. -
φ=arcsin(A X /A) -
θ=arcsin(A Y /A) (Equation 2) - The
processor 50 compensates the field strengths HX, HY, and HZ calculated at the step S430 with the pitch angle φ and the roll angle θ, i.e., the tilt angle, at step S460. That is, theprocessor 50 calculates compensated magnetic field strengthsH X andH Y as expressed inEquation 3. -
H X =H X cos θ+H Y sin θ−H Z cos θ sin φ -
H Y =H Y cos θ+H Z sin θ (Equation 3) - Next, the
processor 50 calculates the azimuth of theputter face 1 e of the golf putter 1 from the magnetic field strengthsH X andH Y compensated with the tilt angle as expressed in Equation 4 at step S470. -
Azimuth=arctan(H Y /H X) (Equation 4) - The
processor 50 determines whether the azimuth calculated at the step S470 is the sighted azimuth or not at step S480. The sighted azimuth is an azimuth that is sighted by the user. That is, theprocessor 50 determines whether the sighted azimuth corresponds to an azimuth that is first calculated by theprocessor 50 after theprocessor 50 receives the start signal through theinput unit 20. - When the calculated azimuth is the sighted azimuth, the
processor 50 adds the rotation angle to the sighted azimuth so as to calculate an aligning azimuth at step S481, and then, theprocessor 50 repeats the step S430. The aligning azimuth is an azimuth of theputter face 1 e when thedestination line 3 is perpendicular to the reference line, i.e., theputter face 1 e of the golf putter. When the azimuth is not the sighted azimuth, theprocessor 50 determines whether the difference between the azimuth and the aligning azimuth is within the range of the acceptance angle at step S482. - When the difference is not within the range of the acceptance angle, the
processor 50 repeats the step S430. When the difference is within the range of the acceptance angle, theprocessor 50 outputs the reporting signal through theoutput unit 60 at step S490. As shown inFIG. 4 , the difference between the azimuth and the aligning azimuth is within the range of the acceptance angle when the rotation angle between theputter face 1 e and thedestination line 3 is substantially 90°. - According to the first exemplary embodiment, since the user can know when the angle between the reference line, i.e., the
putter face 1 e, and the destination line is within the acceptance angle, which is the acceptable error range of the rotation angle, theputter face 1 e can be perpendicular to the destination line, i.e., a putting linear line. - While the aligning
apparatus 100 has been applied to the golf putter to align the putting linear line in the first exemplary embodiment of the present invention, the aligningapparatus 100 may be used to align an address setup position. A second exemplary embodiment will be described with reference toFIG. 6 andFIG. 7 . - In the second exemplary embodiment of the present invention, it is assumed that the reference line for aligning is a virtual line (hereinafter referred to as “both shoulders line”) connecting both feet of the user and/or both shoulders of the user. An aligning apparatus according to the second exemplary embodiment is installed on the user (not shown). The golf putter 1 (
FIG. 2 ) of the second exemplary embodiment is a golf club. -
FIG. 6 shows a state in which the both shoulders line is sighted to be perpendicular to the destination line, andFIG. 7 shows a state in which the both shoulders line is aligned to be parallel to the destination line. - The aligning apparatus according to the second exemplary embodiment of the present invention is used to align the both shoulders line 4 to be parallel to the destination line when the user swings the golf club. As shown in
FIG. 6 , a start signal is input to theinput unit 20 after the reference line, i.e., the both shoulders line 4, is sighted to be perpendicular to the destination line. Then the 3-axismagnetic resistance sensor 30 and the 3-axis accelerometer 40 measure an azimuth of the both shoulders line 4 when the user rotates. Next, when the azimuth of the both shoulders line 4 according to the rotation of the user's body is within the range of the acceptance angle (e.g., +0.5°) compared with the aligning azimuth, theprocessor 50 outputs the reporting signal through theoutput unit 60. As a result, the user can find the address setup position for aligning the both shoulders line 4 to be parallel to the destination line as shown inFIG. 7 . - While the aligning
apparatus 100 has been described to be formed by one apparatus as shown inFIG. 1 in the first and second exemplary embodiments of the present invention, the aligningapparatus 100 may be formed by at least two modules, and these modules may communicate with each other.
