A sensing device with a camera unit and image processing means that captures and processes images to detect the golf ball's position and trajectory, using a grabber to collect and store images, a shot detector to sense hitting preparation and completion, and an image processing unit to extract physical properties of the moving ball, without the need for additional trigger sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional trigger sensors are used to accurately detect hitting events, then sensing accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple functions into the existing camera system: ball position detection, hitting event detection, and trajectory tracking are all performed using the same capturing means and image processing means, eliminating the need for separate trigger sensors
Solution Approach 2:
The capturing means and image processing means are designed to perform multiple functions: detecting ball position, determining hitting events through image analysis, and tracking ball trajectory, making the system multi-functional without additional sensors
2Measurement precision
If additional trigger sensors are used to accurately detect hitting events, then sensing accuracy is improved, but cost increases
Solution Approach 1:
The system uses optical copying through image capture and processing to detect hitting events, replacing the need for expensive electronic trigger sensors with a more cost-effective vision-based approach
Solution Approach 2:
The patent employs a cost-effective camera system and image processing approach rather than expensive trigger sensors, achieving accurate hitting detection through software-based image analysis
3Adaptability or versatility
If the swing plate is sloped at a predetermined angle to realize slope, then virtual reality is improved, but ball position detection accuracy deteriorates
Solution Approach 1:
The patent addresses the slope detection challenge by analyzing the two-dimensional image data from the camera and using image processing algorithms to calculate three-dimensional ball position and trajectory, compensating for the sloped plate geometry
Solution Approach 2:
The image processing means adjusts detection parameters and calculations based on the known slope angle of the swing plate, compensating for the inclined geometry to maintain accurate ball position detection
