Golf Digest System Using Dual Cameras for Ball Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf digest creating systems struggle to clearly record the movement of a golf ball and undulations at the shot spot, especially when the golf cart is away from the player, and require players to focus on shooting rather than playing, limiting their ability to concentrate on the game.
Innovation Solution
A golf digest creating system equipped with a 360-degree camera and a motorized-zoom-lens-equipped camera on a golf cart, utilizing GPS and course information to automatically capture and store video and audio data, allowing for clear visualization of ball movement and undulations without player intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a 360-degree camera is used to capture golf play, then the coverage area is improved, but the ability to clearly record ball movement and undulations deteriorates
Solution Approach 1:
The system divides the recording function into two separate cameras: a 360-degree camera for comprehensive coverage and a zoom lens camera for detailed ball movement recording. Each camera performs its specialized function, resolving the contradiction between wide coverage and detailed precision.
Solution Approach 2:
Different parts of the recording system have different qualities - the 360-degree camera provides broad area coverage while the zoom lens camera provides high-detail local recording of ball movement. This local quality differentiation resolves the contradiction between coverage area and measurement precision.
2Ease of operation
If the golf cart is positioned away from the player, then the player's movement freedom is improved, but the ability to clearly record ball movement deteriorates
Solution Approach 1:
The system replaces the mechanical requirement of close proximity with optical zoom capability. The zoom lens camera captures detailed ball movement from a distance, eliminating the need for the golf cart to be positioned near the player while maintaining recording quality.
3Ease of operation
If a player performs manual shooting during play, then the recording control is improved, but the player's concentration on the game deteriorates
Solution Approach 1:
The system performs automatic recording without requiring player intervention. The controller automatically operates the zoom lens camera based on detected ball movement, allowing the player to focus entirely on playing while the system handles recording independently.
Solution Approach 2:
The system uses strong automated detection and control mechanisms to accelerate the recording process, capturing ball movement automatically without waiting for player action. This automated acceleration resolves the contradiction between control and concentration.
4Quantity of substance
If only highlight scene video is recorded, then the data volume is reduced, but the ability to recognize detailed undulations deteriorates
Solution Approach 1:
The system segments the recording into two streams: comprehensive 360-degree video for context and targeted zoom lens video for detailed undulation recording. This segmentation allows detailed undulation recognition in highlight scenes without requiring excessive data volume.

AI summary
A mobile imaging unit includes a 360-degree camera disposed on a golf cart, a motorized-zoom-lens-equipped camera on a motorized camera platform, a microphone, a GPS receiver, and a direction detector of a lens. The mobile imaging unit determines an imaging target area of the motorized-zoom-lens-equipped camera by using a current position and golf course map information, drives the motorized camera platform, and stores video data captured in a magnified state, with the video data being accompanied by time information and area identification information. A digest creating device selects, as video data to be subjected to image analysis and extraction of a highlight scene, either video data from the 360-degree camera or video data from the motorized-zoom-lens-equipped camera in accordance with the area identification information accompanying the stored video data.
