Vehicle Hazard Image Alerts From Dashcam Event Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle traffic assistance methods provide limited information on traffic events, making it difficult for drivers to understand the detailed situation of an upcoming traffic event based on icons or character information.
Innovation Solution
An information providing device and method that captures video data from a first vehicle using a dashboard camera, extracts relevant image data, and transmits it to a second vehicle for display on its dashboard, allowing the driver to see the actual situation of the traffic event before reaching the occurrence site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If icon or character information is used to notify drivers of traffic events, then the information transmission is simple and quick, but the driver cannot understand the detailed situation of the traffic event
Solution Approach 1:
The patent uses dashboard camera video data to create visual copies of the actual traffic event scene. These video copies are then transmitted to other vehicles' display devices, allowing drivers to see realistic representations of hazards (accidents, construction, congestion) rather than abstract icons. This copying approach preserves complete information about the traffic event while maintaining relatively simple system implementation through existing camera and communication infrastructure.
2Loss of information
If detailed video data is transmitted to all vehicles, then drivers can understand the detailed situation, but the communication network load and data transmission time increase
Solution Approach 1:
The patent extracts only the necessary video data from dashboard cameras - specifically, video segments capturing traffic events that require cautious driving. Rather than transmitting all video data continuously, the system identifies and extracts relevant portions (accidents, construction zones, congestion) and transmits only those extracted segments to vehicles in the communication network. This extraction approach provides complete information about hazards while minimizing data transmission time and network load.
3Loss of information
If real-time video transmission is implemented for all traffic events, then drivers receive complete information, but the energy consumption and processing requirements increase significantly
Solution Approach 1:
The patent implements preliminary action by having dashboard cameras continuously capture and buffer video data before traffic events occur. When a traffic event is detected (through sensor data or manual input), the system has already prepared the relevant video segments for transmission. This preliminary capture approach ensures complete information is available immediately when needed, without requiring high-energy real-time processing and transmission during critical moments. The energy-intensive recording happens continuously at low power, while high-power transmission occurs only when hazards are detected.
Data Source
AI summary
An information providing device and an information providing method are provided. Processing circuitry receives, from a first vehicle, a piece of video data related to the moment the first vehicle passed an occurrence site. The first vehicle captures a piece of video data by a dashboard camera when passing the occurrence site of a traffic event requiring cautious driving. The processing circuitry extracts a piece of image data representing a situation of the occurrence site from the video related to the piece of video data, and transmits the piece of image data to the second vehicle. When the second vehicle reaches a notification location, a display device of the second vehicle displays an image related to the piece of image data in order to issue an alert.
