Camera Control for Sports Events Using Motion Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sport event broadcasting relies heavily on manual camera control, which can lead to missed or poorly captured interesting events due to the reliance on human skill and timing, resulting in inconsistent quality and accuracy.
Innovation Solution
A method and apparatus that utilize a computer system to receive images of a sport event, track the motion of objects, detect predefined positional relations, and automatically initiate higher pixels-to-time ratio image streaming by selected cameras, ensuring accurate and timely capture of critical events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual camera control is used by cameramen and directors, then operational flexibility and adaptability are maintained, but measurement precision and reliability of capturing critical events deteriorate due to human error and inconsistency
Solution Approach 1:
The patent replaces the manual mechanical control system (cameramen operating cameras) with an automated computer-controlled system. The system uses image processing algorithms to automatically detect objects, track their motion, identify critical events based on predefined positional relations, and control camera streaming without human intervention, thereby improving measurement precision while increasing automation extent.
2Measurement precision
If higher pixels to time ratio is used for capturing all events, then quality and accuracy of captured footage is improved, but data transmission bandwidth and processing requirements increase significantly
Solution Approach 1:
The patent applies local quality by using high pixels-to-time ratio (high-quality capture) only for specific regions and events that are identified as critical, while using lower pixels-to-time ratio for other areas and times. The system dynamically adjusts capture quality based on detected object positions and event significance, ensuring high footage quality for important moments while minimizing overall data transmission volume.
3Reliability
If multiple cameras operate at high pixels to time ratio continuously, then comprehensive coverage and reliability of event capture is improved, but energy consumption and device complexity increase
Solution Approach 1:
The patent implements periodic action by having cameras operate at high pixels-to-time ratio only during specific periods when critical events are detected, rather than continuously. The system switches between low and high capture modes based on real-time event detection, maintaining reliable event capture during critical moments while significantly reducing overall energy consumption of the camera system.

AI summary
A method for controlling cameras in a sport event, the method comprising steps executed by at least one computer, the steps comprising: during a sport event taking place in a constrained environment, receiving images of the sport event, the images being captured with a first pixels to time ratio, tracking a motion of a first object, using the images being captured with the first pixels to time ratio, detecting an arrival of the first object into a predefined positional relation to a second object during the tracked motion, and upon the detected arrival, initiating streaming of images being captured with a pixels to time ratio higher than the first pixels to time ratio by at least one selected camera.
