Dynamic Region Setting for Traffic Camera Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of connected cameras in traffic monitoring systems increases, the monitoring load also increases, making it difficult for a single person to manage, and existing methods for setting important regions in images captured by cameras installed in dynamic situations are not effective in ensuring appropriate region selection.
Innovation Solution
A device and method that dynamically change the important region within the camera's field of view based on the lighting state of traffic signals, allowing for real-time notification and encoding of images using these regions, thereby optimizing image quality and reducing data transmission load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the number of connected cameras is increased to improve monitoring coverage and information availability, then the monitoring load increases making it difficult for a single person to manage
Solution Approach 1:
The patent extracts and highlights only the important regions in video feeds from multiple cameras, rather than requiring operators to view entire video streams. By identifying and isolating regions containing traffic signals, pedestrians, vehicles, or other relevant objects, the system presents only essential information to operators, thereby reducing monitoring load while maintaining comprehensive coverage from multiple cameras
Solution Approach 2:
The system introduces an automatic recognition technology as an intermediary between multiple cameras and the human operator. This intermediary automatically processes video feeds, identifies important regions, and presents processed information to the operator, eliminating the need for the operator to directly monitor all camera feeds while still benefiting from expanded coverage
2Adaptability or versatility
If the important region is set as long as the related object appears, then the region may be inappropriate in images captured by cameras installed in locations where the situation changes from moment to moment
Solution Approach 1:
The patent implements dynamic region setting that automatically adapts to changing situations. The system continuously monitors video feeds and adjusts the important region boundaries in real-time based on the current state of traffic signals, pedestrian positions, vehicle movements, and other dynamic factors. This ensures that the important region accurately reflects the current situation rather than relying on fixed or static definitions
Solution Approach 2:
The system incorporates feedback mechanisms where the automatic recognition technology continuously analyzes the current scene state and adjusts the important region settings accordingly. By feeding back information about detected objects, their positions, and the current traffic signal state, the system dynamically refines region boundaries to maintain high accuracy even as situations change moment to moment
