XR Golf Device Combining Camera Ball Tracking and Swing Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual golf systems lack the ability to comprehensively analyze a user's golf swing and its impact on the ball's trajectory, leading to a sense of disconnection from real golf experiences.
Innovation Solution
Utilize eXtended Reality (XR) devices equipped with cameras and artificial neural network models for real-time analysis and reproduction of golf swing motions, incorporating object detection, pose estimation, scaling, and motion prediction to enhance immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a stereoscopic method using two cameras is used to obtain three-dimensional coordinates of the golf ball, then the position information of the golf ball can be calculated, but the system cannot analyze the user's motion or the corresponding swing trajectory of the golf club
Solution Approach 1:
The sensing device is designed to perform multiple functions: it not only calculates the three-dimensional coordinates and position information of the golf ball using stereoscopic camera methods, but also analyzes the user's motion and swing trajectory of the golf club. This multi-functional approach allows a single system to provide comprehensive data for both ball tracking and swing analysis, eliminating the need for separate analysis systems.
2Reliability
If conventional virtual golf simulation devices are used, then a realistic experience similar to actual golf can be provided, but the system lacks comprehensive analysis capability of user actions and their impact on golf swing
Solution Approach 1:
The patent merges the realistic golf simulation experience with comprehensive swing analysis capabilities into a single integrated system. The sensing device combines ball tracking functions with user motion analysis functions, allowing the system to simultaneously provide realistic virtual golf experience and detailed swing trajectory analysis without requiring separate complex systems.
Solution Approach 2:
The virtual golf simulation device is designed with multi-functionality, serving both as a realistic golf experience platform and as a comprehensive swing analysis system. The sensing device can simultaneously track the golf ball, analyze user motion, and provide swing trajectory information, making the device versatile and reducing overall system complexity.

AI summary
One example relates to a method for providing an immersive virtual golf service using an eXtended Reality (XR). The method may comprise: capturing an image of an actual golf ball placed on a ground through a camera of an XR device; reproducing and displaying the image within a virtual golf environment displayed on a display unit of the XR device; capturing, in real-time, a golf swing of a user through the camera of the XR device; analyzing a golf swing motion of the user in real-time using an artificial neural network model; and reproducing and displaying the analyzed golf swing motion within the virtual golf environment displayed on the display unit of the XR device.
