Golf Simulator Trajectory Calculation Using Orthogonal Planes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf simulators experience significant simulation delays, often taking 4 or more seconds for the simulated golf ball to appear on the display after a physical ball is struck, which detracts from the user's experience.
Innovation Solution
A golf simulator system incorporating a stereographic image capture system with cameras and a computer that determines the initial trajectory of a golf ball using linear expressions, adjusts for variations based on orthogonal planes, and generates simulation data for a virtual golf ball flight path, allowing the simulated ball to appear on the screen within 1 second of the physical ball strike.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional golf simulator processing methods are used, then comprehensive ball flight analysis can be achieved, but simulation delay increases to 4 or more seconds
Solution Approach 1:
The patent divides the trajectory calculation into two independent segments: (1) determining initial ball parameters (launch angle, speed, spin) using image capture and linear expressions, and (2) calculating trajectory variations using orthogonal planes. This segmentation allows parallel processing of different calculation components, reducing overall computation time while maintaining comprehensive analysis accuracy.
Solution Approach 2:
The system pre-establishes the orthogonal plane reference frames and linear expression models before ball flight occurs. During actual operation, the computer only needs to substitute measured values into these pre-configured mathematical models, significantly reducing real-time computation requirements and enabling faster simulation response.
2Measurement precision
If complex trajectory calculations are performed, then simulation accuracy is improved, but processing speed decreases
Solution Approach 1:
The patent replaces complex iterative mechanical calculation methods with direct mathematical substitutions using linear expressions and orthogonal plane geometry. By substituting measured ball parameters directly into pre-established mathematical models, the system achieves accurate trajectory calculation without requiring time-consuming iterative simulations.
Solution Approach 2:
The system transforms the complex three-dimensional trajectory problem into a series of simpler calculations by changing the parameter representation method. Using orthogonal planes allows the decomposition of 3D trajectory into independent 2D plane calculations, which can be processed more efficiently while maintaining overall accuracy.
