Golf Swing Path Analysis Using Reference and Downswing Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
General golf players lack the knowledge to determine if their swing is correct, as existing techniques do not provide clear guidance on appropriate swing angles and paths.
Innovation Solution
A golf swing analysis system that captures video images, specifies reference angles based on body positions and shaft positions, compares downswing angles, and identifies swing paths using a mobile device, allowing players to assess their swing accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a histogram displaying swing parameters is provided, then measurement precision is improved, but ease of operation deteriorates because general players cannot interpret the data
Solution Approach 1:
The patent introduces an intermediary evaluation system that translates complex swing parameters into simple pass/fail judgments. The system compares measured parameters against reference values and provides intuitive feedback indicating whether the swing is appropriate, serving as a mediator between precise measurement and player understanding
Solution Approach 2:
The patent employs visual indicators such as color-coded displays to represent swing quality. By using color changes (e.g., green for appropriate, red for inappropriate), the system makes swing evaluation immediately recognizable to players without requiring technical knowledge of swing parameters
2Measurement precision
If detailed swing parameters are displayed, then measurement precision is improved, but device complexity increases due to multiple detection requirements
Solution Approach 1:
The patent employs a mobile terminal that performs multiple functions: capturing video images, detecting swing parameters, comparing with reference values, and providing evaluation feedback. By consolidating these functions into a single universal device, the system achieves precise measurement without proportionally increasing overall system complexity
Solution Approach 2:
The patent replaces complex mechanical detection systems with image processing and computer vision algorithms. By using video image analysis to detect swing parameters, the system achieves precise measurement while reducing mechanical complexity through software-based solutions
3Measurement precision
If reference angles are specified based on body positions, then measurement precision is improved, but difficulty of detecting and measuring increases
Solution Approach 1:
The system automatically detects body part positions and calculates reference angles without requiring manual input or adjustment by the player. The mobile terminal autonomously performs video analysis, identifies key body positions, and computes reference values, making the measurement process self-service and reducing operational difficulty

AI summary
A captured video image obtaining unit 70 obtains a captured video image in which a player making a golf swing is captured. A swing path type specifying unit 86 specifies at least one reference angle based on at least one of a position of a predetermined body part of the player at address or a position of a shaft at address, where the positions are specified based on the captured video image. A swing path type specifying unit 86 specifies a downswing angle of a club head captured in a captured video image based on the captured video image. The swing path type specifying unit 86 compares the reference angle with the downswing angle.
