Kai Vision is a golf teaching and training system, which consists of a ball data detection sensor (iTrack), a club face detection sensor (iClub), two high-speed cameras, three wireless attitude sensors (hip, shoulder, wrist) and a computer. The system realizes the detection and calculation of the take-off data and trajectory of the ball, the detection of the clubhead surface data at the moment of the impact, and the image analysis of the front / rear side of the swing, such as the snapshot of the key position of the swing, the swing plane, the timing chain of swing power transmission and so on, which provides complete data and video image feedback from the result (the ball's flight) to the reason (the swing) for each swing. The analysis of the causes of errors and the correction of unreasonable movements have an intuitive basis for data, which is a sharp tool for digital teaching and training of golf.
1、 Launch data: ball speed, launch angle, launch direction, total spin, spin axis, sidespin, backspin.
2、 Flight data: landing distance, landing offset, maximum flight height, landing angle, flight time.
3、Trajectory curve: Intuitively display the flight trajectory of the ball in 3D.
Clubhead speed, attack angle, dynamic loft, clubhead path, clubface orientation, clubface loft, impact point, impact efficiency.
The system automatically detects and analyzes key positions during the swing process, such as preparation, takeaway, top, downswing, impact, followthrough, and finish, providing precise and rapid feedback on the moment you are focusing on. This saves you time browsing videos and improves practice efficiency, without affecting your swing rhythm.
The system automatically recognizes and tracks the clubhead trajectory during the backswing and downswing, presenting it as a green line for the backswing and a red line for the downswing, allowing players to clearly visualize their swing path.
By wearing sensors in the hands, shoulders and hips, the angular velocity and angle change curve of the shoulder and hip of the hand will be fed back immediately after the swing is over, in which we can analyze the power order of the hands, shoulders and hips to help us improve the consistency of the swing.
