Method for Evaluating Golf Ball Hitting Process and Golf Club

Smart overview of the Invention

The patent application presents a method for evaluating the golf ball hitting process using a golf club integrated with a processor and various sensors. This system collects diverse data types, including video frames, sound, and posture information, to assess the hitting process. The evaluation results include the ball's contact position on the club face, attributes of the club's contact with the ball and ground, the club's motion trajectory, and the ball's rotation speed. The integration of sensors within the club allows for accurate measurement and analysis of these parameters.

Technical Field

The method is situated in the information processing field, specifically targeting the evaluation of the golf ball hitting process and golf clubs. It addresses the challenges faced by golfers in assessing the contact between the club head and the ball, which is crucial for determining the ball's trajectory and landing point. Traditional methods involving independent equipment like cameras and radar are cumbersome and expensive, with limited accuracy.

Innovation and Advantages

This approach integrates sensors such as image acquisition sensors, inertial measurement units, and microphones into the golf club. This integration facilitates real-time, accurate measurement of the club-ball contact, swing path, speed, and ball trajectory. By embedding these sensors, the method reduces costs and enhances the precision of evaluations, minimizing interference during play.

Methodology

The method involves collecting video frame sequences using one or more image acquisition sensors, obtaining a homography matrix, and converting images for precise contact analysis. It determines the pixel coordinates of the ball's contact point on the club face, improving data processing speed. The use of dual sensors provides three-dimensional coordinates for enhanced accuracy. Additionally, the method calculates the club's motion trajectory by factoring in deformation and posture information.

Evaluation and Analysis

Rotation speed is estimated by analyzing markers on the ball's surface, and contact attributes like order and intensity are derived from sound information. The method identifies the sequence of contact events between the club, ball, and ground, ensuring comprehensive evaluation. This approach not only enhances the accuracy of results but also streamlines the process, making it cost-effective and efficient.
