Description

A hitting evaluation system and method thereof

technical field

The invention relates to the technical field of golf, in particular to a hitting evaluation system and method thereof.

Background technique

A golf course is a venue for playing golf. A standard golf course includes 18 holes (Hole), and each golf hole has a regulated number of strokes, called a par (Par), and the par number is 72 rods. Holes include teeing areas, fairways, greens and hazards. The fairway is the playing area from the teeing area to the green. It is a relatively flat and beautiful playing channel.

Tee area (Tee): The first hitting place for the fairway to serve the ball. Generally, there are Tee-Mark marks on both sides (indicating the front line where the ball is allowed to play), and there is a place within 2 times the length of the club behind the mark line. For the teeing area; in order to be used by different players, and to make the fairway yardage more flexible.

Fairway (fairway): This is the area between the tee area and the green that is often weeded. On the border of the fairway, there is a semi-rough grass area, which is a long grass area or a rough grass area, which is a grass area that has not been trimmed. The center of the fairway is the best shot path from the tee to the green.

Green (Green): Tightly mowed grass specially prepared for putting, in which a hole is dug where the ball will be driven into the putt. The green is separated from the fairway by a fringe with grass longer than the green but shorter than the fairway. Greens are usually at the end of the fairway, on slightly undulating terrain; greens are generally irregular in shape.

There are two ways for golfers to improve their level: one, eliminate or reduce inconsistency (reduce inconsistency); two, improve technology (improve the technique). In order to increase or reduce the degree of inconsistency, it is important for the golfer to understand the difference in swing dynamics between strikes and strikes. If golfers know the causes of bad shots or inconsistencies, they can develop strategies to avoid these causes.

The act of tallying scores while playing golf is a management activity that golfers choose to avoid if possible. Because the act of counting scores requires the golfer to concentrate at the end of each hole when the golfer wants to relax or focus on other things. Therefore, a system that can automatically count scores is of great help to golfers. In the longer term, a system for calculating key statistics would give golfers greater insight into their golf game and therefore help improve their first-time performance, such as the number of putts, The number of golf balls that deviate from the fairway (fairways missed) and so on.

A golfer may have good instruction from a coach, or may be able to learn the proper theory to improve their game, but often there is a problem with incorrect application. It would be very useful for a golfer if there is a system that can monitor the key swing dynamics in real time and feed back the monitoring information (for example, whether the theory is being applied correctly) to the golfer in real time. A persistent problem for golf coaches and students is the long-standing interpretive gap between coaching instruction and practical application.

In order for the key swing characteristic statistics assigned to targets to be meaningful to targets, those targets themselves must be meaningful. A common mistake of unsupervised golf training systems is that they assume that all golfers are the same and should be judged by the same standards. But that's clearly not the case: different golfers have different physical characteristics, different time and determination to improve their golf, different core attributes of the swing. Therefore, it is important to give golfers a variety of options when setting goals.

Specifically, as shown in Figure 3(a), the first swing feature point preparation posture (address) is the initial action of the full swing action. The golfer holds the club with the palms of both hands facing each other, and keeps the feet open to maintain an appropriate distance. Properly bend the knee joint, lean the trunk forward, maintain a certain angle between the arm and the trunk, and when the club head lightly touches the ground, the spatial position where the position sensor is located. In this embodiment, the position sensor is located at the lowest point of the swing trajectory diagram and its tangent is parallel to the horizontal plane.
