Apparatus for selecting high-quality golf ball
Disclosed is an apparatus for selecting a high-quality golf ball, the apparatus including a measurer configured to transmit a signal toward a golf ball and receive a signal reflected from the golf ball or a signal transmitted through the golf ball; and an analyzer configured to select a golf ball by analyzing the received signal.
1. An apparatus for selecting a high-quality golf ball, comprising:
a measurer configured to transmit a signal toward a golf ball and receive a signal transmitted through the golf ball; and
an analyzer configured to select a golf ball by analyzing the received signal,
wherein the measurer comprises:
a rotary supporter configured to rotatably support the golf ball;
an electromagnetic wave transmitting antenna disposed at a first side of the golf ball and configured to transmit electromagnetic waves toward the golf ball; and
an electromagnetic wave receiving antenna disposed at a second side of the golf ball and configured to receive electromagnetic waves transmitted from the electromagnetic wave transmitting antenna.
2. The apparatus of claim 1 , wherein;
the rotary supporter comprises a golf ball supporter to support the golf ball to be vertically spaced apart from the ground; and a rotation unit to rotate the golf ball supporter with respect to a vertical axis, and
the apparatus further comprises a first antenna supporter and a second antenna supporter that are spaced apart from the golf ball supporter and respectively support the electromagnetic wave transmitting antenna and the electromagnetic wave receiving antenna to be located on a same horizontal plane as the golf ball supported by the golf ball supporter.
3. The apparatus of claim 2 , further comprising a base configured to support the golf ball supporter and the antenna supporter on one side thereof,
wherein the base comprises an absorber attached or applied to the one side of the base and configured to absorb diffusely reflected electromagnetic waves.
4. The apparatus of claim 2 , wherein the antenna supporter is slidably provided with respect to the golf ball supporter and adjustable in distance from the golf ball supporter.
5. The apparatus of claim 2 , wherein
the rotary supporter comprises:
a first rotation supporting plate configured to support a first point on a lateral side of the golf ball and be rotated by a motor; and
a second rotation supporting plate configured to support a second point on a lateral side of the golf ball and be rotated by a motor.
6. The apparatus of claim 5 , wherein the first point and the second point are two points orthogonal to each other with respect to a center of the golf ball when viewed from top to bottom.
7. The apparatus of claim 5 , wherein the rotary supporter further comprises a roll bar that is freely rotatable at opposite sides thereof, and supports a third point of the golf ball.
8. The apparatus of claim 1 , wherein
the signal comprises electromagnetic waves, and
the apparatus further comprises a detector configured to generate and transceive the electromagnetic waves, and output and detect a magnitude and phase of the received electromagnetic waves.
9. The apparatus of claim 8 , wherein the detector comprises a transmitting circuit and a receiving circuit, comprises a network analyzer, or comprises a signal generator and a spectrum analyzer.
10. The apparatus of claim 1 , wherein the analyzer is configured to select a high-quality golf ball, which is internally and externally uniform and close to symmetry, based on uniformity of a signal received with respect to a plurality of measurement sides while rotating the golf ball.
11. The apparatus of claim 10 , wherein the analyzer is configured to select a high-quality golf ball, which is internally and externally uniform and close to symmetry, based on uniformity of the magnitude and phase of the signal received with respect to the plurality of measurement sides.
12. The apparatus of claim 1 , wherein the analyzer is configured to select a high-quality golf ball, which is internally and externally uniform and close to symmetry, based on a magnitude and phase of the signal received with respect to the plurality of measurement sides based on deep learning.
13. An apparatus for selecting a high-quality golf ball, comprising:
a measurer configured to transmit a signal toward a golf ball and receive a signal reflected from the golf ball; and
an analyzer configured to select a golf ball by analyzing the received signal,
wherein the measurer comprises:
a rotary supporter configured to rotatably support the golf ball; and
an electromagnetic wave transceiving antenna disposed at a first side of the golf ball and configured to transmit electromagnetic waves toward the golf ball and receive reflected electromagnetic waves from the golf ball.
14. The apparatus of claim 13 , wherein;
the rotary supporter comprises a golf ball supporter to support the golf ball to be vertically spaced apart from the ground; and a rotation unit to rotate the golf ball supporter with respect to a vertical axis, and
the apparatus further comprises an antenna supporter that is spaced apart from the golf ball supporter and supports the electromagnetic wave transceiving antenna to be located on a same horizontal plane as the golf ball supported by the golf ball supporter.
