Description

Mobile terminal for providing golf putting line information using LiDAR {MOBILE DEVICE FOR PROVIDING GOLF PUTTING LINE INFORMATION USING LIDAR}

The present invention relates to a mobile terminal for providing golf putting line information, and more particularly to a mobile terminal for providing golf putting line information using a lidar sensor device.

In the case of putting in golf, the golfer accurately grasps information such as the slope around the pin (hole cup) of the golf green (hereinafter, the information around the pin position), and hits the golf ball in the appropriate strength and direction to hit the ball. You have to put it in the pin.

Therefore, because the putt has a very large impact on the score, the information around the position of the pins has been treated as the most important factor in the golf game, and many golfers try to understand the information around the position of the pins before putting on the green. Sit back a few steps, or observe the slope of the green with the ground level and eye level. At this time, in order to determine the inclination between the golf ball and the hole cup, it may be observed from the left or right side, may be observed from the back or the rear of the hole cup, and even minute inclination around the hole cup may be determined.

However, it is very difficult for a golfer or caddy to visually observe the actual green and grasp the overall and accurate information such as the slope around the pin position. Methods of acquiring dimensional shape information and providing the same through a mobile terminal have emerged.

Here, the horizontal measuring aid is attached to the ball marker (ball marker) to measure the inclination of the green at the position of the golf ball, measuring the inclination at the hole cup position to provide the information necessary for determining the putting direction angle do. However, in these horizontal assistive devices, the slope between two points can be measured, but between the golf ball and the pin

The overall slope of the terrain relative to the green is difficult to measure.

So, in recent years, instead of the ball marker, a method of mounting and utilizing the tilt measurement app on a smartphone equipped with an inclination sensor has appeared, but this is the same method as the ball marker method, and the measuring means have only been replaced by smartphones. Still, the overall terrain slope of the green between the golf ball and the pin is difficult to measure.

On the other hand, there is a method for providing information obtained through the measurement of the green 3D shape information through the mobile terminal, this method can provide the slope information of the green most accurately.

This method uses a high-precision laser scanner to measure the position (latitude, longitude) and altitude (height) of grid points on the green, which are several centimeters apart, to obtain three-dimensional shape information of the entire green, How to give information to golfers

However, the high-precision laser scanner is difficult to carry, and therefore, there is a problem in that the three-dimensional shape information can be used only in a golf course obtained in advance.

The present disclosure intends to present technical features related to a mobile terminal for providing golf putting line information using a lidar sensor device.

According to an exemplary embodiment of the present disclosure, as a mobile terminal for providing golf putting line information, a green detection line for sensing a golf course green attached to at least one surface of the mobile terminal to generate a 3D green image ( LIDAR) sensor unit; A camera unit photographing a golf green formed on at least one surface of the mobile terminal to allow the controller to acquire position information of the ball and position information of the hole; It may include, may provide a mobile terminal for providing golf putting line information.

Putting trajectory property simulation is generally simulated by using the principle of force, such as the force applied when hitting the golf ball, the static friction applied between the golf ball and the green, and the motion friction force that occurs as the golf ball rolls (translation friction and rotational). The location of the ball (latitude, longitude, altitude) is calculated using the numerical method, taking into account friction, and gravity caused by the inclination of the green. At this time, if the minimum speed and the maximum speed for the golf ball to enter the hole cup is specified in advance, the golf ball enters the hole cup while drawing different trajectories according to the putting strike strength.

In addition, since the golf ball is pushed but proceeds while rotating, the golf ball is initially pushed by the hitting method, and is moved while the spin occurs due to the friction and gravity of the green. On the other hand, the golf ball by the rolling method is rotated from the beginning to move responsibly sensitive to the inclination. Therefore, the trajectory by the hitting method and the trajectory by the rolling method have different forms.

In detail, while the green detection lidar sensor unit 100 senses the golf course green, there may be a change in the position of the mobile terminal 1000 or the angle of sensing may be changed abruptly. In this case, the controller 120 removes the error using the obtained current position and angular velocity of the mobile terminal 1000 and causes the 3D green image correction unit 121 to generate the 3D green image generated by reflecting the error.
