Roadside Detection Device Selecting Cameras for Traffic Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic monitoring systems fail to accurately record image information of vehicles that ignore traffic signals, as they do not appropriately select and instruct cameras to capture images of detected events.
Innovation Solution
A detection device and method that acquires sensor information to detect events and selects the appropriate camera from multiple cameras installed on the road to capture and record image information, ensuring accurate recording of events like overspeeding, wrong-way traveling, and other critical road occurrences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cameras are installed on the road to capture images of detected events, then the accuracy of recording image information is improved, but the device complexity increases
Solution Approach 1:
The system automatically selects the appropriate camera based on the detected event type and location, without requiring manual intervention. The detection device autonomously determines which camera should capture the image, making the system self-service in terms of camera selection and instruction issuance.
Solution Approach 2:
Multiple cameras are pre-installed at different locations on the road, and their coverage areas are predetermined. When an event is detected, the system can quickly identify which pre-positioned camera should capture the image, eliminating the need for real-time camera positioning or selection deliberation.
2Reliability
If a sensor continuously monitors the road to detect events, then the reliability of event detection is improved, but the energy consumption increases
Solution Approach 1:
The sensor performs periodic monitoring of the road, detecting events at regular intervals rather than continuously. This periodic detection maintains reliability for catching traffic violations while reducing overall energy consumption compared to uninterrupted continuous monitoring.
Solution Approach 2:
The system uses feedback from the sensor detection results to control camera operation. When an event is detected, the system activates the appropriate camera to capture images. This feedback mechanism ensures reliable event detection while avoiding unnecessary camera operation during normal conditions, thereby reducing energy consumption.
