Virtual Golf Simulation Adjusting Ball Flight Distance by Landform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual golf simulation systems fail to accurately replicate the differences in golf shots based on various landforms of a real golf course when a user practices on a golf mat, resulting in a lack of realism in virtual golf simulations.
Innovation Solution
A virtual golf simulation apparatus and method that includes a sensing device to track the golf ball's movement, an image processing unit to simulate the ball's trajectory, and a control unit to adjust the ball flight distance based on the landform, using a golf mat with fairway and trouble regions to simulate the real golf course environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual golf simulation is carried out irrespective of the hitting environment based on the golf mat, then the simulation can be performed without complex adjustments, but the virtual golf rounding becomes considerably different from the real golf course experience
Solution Approach 1:
The patent applies local quality by dividing the golf mat into multiple regions (fairway region, rough region, bunker region) with different characteristics, and applying different ball flight distance decreasing rates to each region. This allows the simulation to reflect local environmental differences while maintaining overall system operation, resolving the contradiction between operational simplicity and simulation realism.
2Measurement precision
If the ball flight distance is adjusted based on the landform in the virtual golf course, then the simulation accuracy is improved, but the device complexity increases due to additional control unit functions
Solution Approach 1:
The patent implements preliminary action by pre-storing multiple ball flight distance decreasing rates in the control unit, each corresponding to a specific landform type (fairway, rough, bunker). During simulation, the system simply retrieves and applies the appropriate pre-calculated rate based on the detected landform, avoiding complex real-time calculations and reducing device complexity while maintaining high simulation accuracy.
3Reliability
If the golf mat is divided into multiple regions with different artificial turf states, then the hitting environment similarity to real golf course is improved, but the manufacturing complexity of the golf mat increases
Solution Approach 1:
The patent applies local quality by creating different regions on the golf mat with distinct artificial turf characteristics (fairway, rough, bunker regions). Each region uses turf with properties mimicking its real-world counterpart, providing authentic hitting feedback. This regional differentiation enhances environment similarity while using standardized manufacturing techniques for each zone, balancing realism with manufacturability.

AI summary
Disclosed herein are a virtual golf simulation apparatus and method that is capable of applying differences between golf shots based on kinds of a landform of a real golf course when a user performs a golf rounding in the real golf course to hitting environment based on a golf mat, on which the user hits a golf ball, and to a virtual golf course through virtual golf simulation, and that is capable of simultaneously and properly reflecting the hitting environment of the user and the environment of the virtual golf course in simulation results, thereby providing the same sense of reality that the user would feel in the real golf course.
