Basketball Ball Feeder Tracking for Dispersed Shot Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to accurately track player performance and shot criteria in dispersed basketball games, such as knockout and horse, across multiple courts, due to difficulties in consistently tracking shooter positions and verifying shot emulation.
Innovation Solution
A dispersed game tracking system utilizing sensors and processors to identify players and track basketball motion, determine shot types, and provide real-time feedback, enabling gameplay across dispersed locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor data from multiple sensors is collected to track player performance, then measurement precision is improved, but processing resources and data volume increase
Solution Approach 1:
The patent extracts and processes only the most relevant sensor data (position, velocity, acceleration) while filtering out redundant information. The system selectively processes data from a subset of sensors rather than processing all sensor data, thereby reducing processing resources while maintaining tracking accuracy.
Solution Approach 2:
The patent segments the sensor data processing into distinct modules: data collection, data filtering, player identification, and performance evaluation. This segmentation allows the system to process data in manageable stages, reducing the processing burden on resources while maintaining comprehensive tracking capability.
2Measurement precision
If multiple sensors are used to track ball motion and player positions, then measurement precision is improved, but loss of information increases due to network delay
Solution Approach 1:
The patent performs preliminary actions by pre-calculating expected ball trajectories and pre-establishing reference frames. The system predicts where the ball should be based on previous motion patterns and compares this with actual sensor data, compensating for network delays in real-time processing.
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously compares expected ball positions (based on predicted trajectories) with actual sensor measurements. This feedback loop allows the system to correct for network delays and maintain real-time accuracy by adjusting predictions based on actual observed behavior.

AI summary
A ball feeding system has a ball feeder that is configured to receive a basketball and launch the basketball to a shooter for enabling the shooter to shoot the basketball toward a basketball goal. The ball feeder is coupled to a sensor (e.g., a camera) by an arm that extends from the ball feeder, and the sensor is configured to sense the basketball as it is traveling on a trajectory toward the basketball during a shot of the basketball by the shooter. At least one processor is configured to determine, based on the sensor, at least one trajectory parameter indicative of the trajectory and provide feedback indicative of a performance of the shooter in shooting the basketball.
