Outdoor Lamp Camera Road Condition Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for improving driving safety focus on detecting vehicle surroundings but fail to effectively provide timely road condition information from distant locations, leading to potential accidents and traffic jams.
Innovation Solution
A system comprising an outdoor lamp with a camera that captures images, performs image recognition to identify events, generates road condition messages with location and event information, and broadcasts these messages to vehicles, using a processor, storage circuit, and transceiver to ensure only eligible vehicles receive relevant information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If current systems focus on detecting vehicle surroundings, then local safety information is provided, but distant road condition information cannot be detected timely
Solution Approach 1:
The patent introduces outdoor lamps with integrated cameras as intermediary devices positioned along roads to capture and transmit road condition information. These lamps act as mediators between the road environment and vehicles, enabling distant road condition detection without requiring vehicles to have direct line-of-sight sensors. The lamps capture images of road conditions (accidents, obstacles, weather) and transmit this information to vehicles proactively, resolving the contradiction by providing both timely detection and comprehensive information coverage.
2Loss of information
If road condition information is broadcast to all vehicles, then information dissemination is comprehensive, but non-eligible vehicles receive unnecessary messages
Solution Approach 1:
The patent implements local quality by differentiating information delivery based on vehicle characteristics and locations. The outdoor lamps transmit road condition information selectively to vehicles that meet specific criteria (eligible vehicles), such as those in affected areas or with relevant sensor capabilities. This targeted approach ensures comprehensive information coverage for vehicles that need it while avoiding unnecessary transmissions to vehicles that cannot utilize the information, thereby optimizing communication bandwidth usage.
3Measurement precision
If image recognition is performed continuously, then event detection accuracy is improved, but processing time and energy consumption increase
Solution Approach 1:
The patent employs periodic action by implementing event-driven image recognition rather than continuous processing. The outdoor lamps capture images continuously or at regular intervals, but image recognition and analysis are triggered only when specific conditions are met (e.g., detection of potential events, changes in road conditions, or at scheduled intervals). This approach maintains high event detection accuracy for critical situations while significantly reducing processing time and energy consumption during normal conditions.

AI summary
A system for providing road condition information includes a first outdoor lamp and a first camera. The first camera is disposed on the first outdoor lamp and configured to: capture an image of a surrounding of a location where the first camera is located; perform an image recognition process on the image to identify an event occurring in the surrounding; generate, based on the event, a first road condition message including location information of the event and event information of the event; and broadcast the first road condition message to a first vehicle.
