Golf Swing Segment Analysis Using Image Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for analyzing golf swings fail to provide detailed analysis of segments constituting a golf swing and do not offer adequate feedback to users, which hinders skill improvement.
Innovation Solution
A method and system that acquire two or more images of a golf swing, compare them to generate information on segments constituting the swing, and provide feedback by comparing this information with reference data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional video analysis method is used, then the golf swing can be analyzed, but detailed analysis of segments constituting the golf swing cannot be performed
Solution Approach 1:
The golf swing is divided into multiple segments (back swing segment, down swing segment, etc.) based on temporal characteristics. By segmenting the swing motion and analyzing each segment separately using image frames, the system achieves detailed segment analysis while preserving time information through frame-based temporal tracking.
2Loss of information
If conventional video analysis method is used, then the golf swing can be analyzed, but adequate feedback on segment analysis results is not provided to the user
Solution Approach 1:
The system compares the analyzed segment information with reference information and generates feedback results that are provided to the user. This feedback mechanism enables users to understand their swing characteristics and receive guidance for improvement, directly addressing the need for actionable information in skill development.
3Device complexity
If sensor with low frame rate is used, then the system can operate with simpler equipment, but segments constituting the golf swing cannot be precisely separated
Solution Approach 1:
The system performs preliminary analysis by comparing adjacent image frames to identify temporal characteristics and segment boundaries before final segmentation. This preliminary frame comparison enables precise segment separation even when using sensors with lower frame rates, as the system leverages the temporal information available in consecutive frames to accurately delineate swing segments.
Data Source
AI summary
A method for providing information on segments constituting a golf swing is provided. The method includes the steps of: acquiring two or more images of a golf swing; and generating information on at least one segment constituting the golf swing with reference to a result of comparing the two or more images.
