Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indoor golf training systems, such as screen golf, are not effective in analyzing ball trajectories or correcting putting techniques, as they do not provide an environment similar to a real golf field.
Innovation Solution
A putting guide system that uses a camera and projector to create a virtual putting environment, allowing users to practice putting while tracking the ball's trajectory and providing statistical data for improvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If screen golf is used for indoor training, then the training space can be utilized, but the ball trajectory analysis and putting correction capabilities are lost
Solution Approach 1:
The patent creates a virtual copy of the real putting environment using image processing technology. The camera captures the actual putting scene, and the control module generates a virtual simulation image that replicates the real field conditions, allowing indoor training while maintaining trajectory analysis capabilities through the virtual environment
Solution Approach 2:
The patent replaces traditional mechanical trajectory measurement devices with an image-based system. Instead of using physical sensors or mechanical tracking equipment, the system uses cameras to capture images and computationally determines ball trajectory through image analysis, providing both indoor training capability and accurate trajectory measurement
2Adaptability or versatility
If a virtual simulation environment is created, then indoor training similar to real field is achieved, but the complexity of the system increases
Solution Approach 1:
The control module serves multiple functions: it processes camera images, determines ball position and trajectory, calculates physical properties of the putting environment, and generates virtual simulation images. By consolidating these functions into a single multi-functional control module, the patent reduces overall system complexity while maintaining real field simulation capability
Solution Approach 2:
The patent introduces a camera as an intermediary device to bridge the real putting environment and the virtual simulation. The camera captures real-world data, which the control module then processes to create virtual representations, simplifying the system architecture by using a single intermediary rather than multiple complex subsystems
3Measurement precision
If physical property information is collected and simulated, then the accuracy of the virtual putting environment is improved, but the time required for setup and calibration increases
Solution Approach 1:
The control module performs preliminary actions by capturing images of the putting environment before the user begins training. It pre-determines physical properties such as green slope and friction coefficient, and pre-calculates trajectory simulations. This preliminary processing establishes an accurate virtual environment in advance, reducing the time needed during actual training sessions
Solution Approach 2:
The system performs self-calibration by automatically capturing images and determining physical properties without requiring manual intervention. The control module independently measures green slope, friction coefficients, and other environmental parameters, eliminating the need for time-consuming manual calibration procedures while maintaining high accuracy
