Event Video Recording Control for Flying and Ground Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dashboard cameras in vehicles, such as flying cars, struggle to appropriately detect and record event video images due to the challenges of accurately identifying events during flight and transitions between flying and ground travel.
Innovation Solution
A recording control apparatus equipped with a video image data acquisition unit, event detection unit, and condition change unit that adjusts event detection criteria based on whether the vehicle is flying, traveling, or engaged in takeoff and landing operations, ensuring appropriate recording of event video data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dashboard camera uses fixed event detection conditions, then the device complexity is reduced, but the reliability of event detection deteriorates when the mobile body transitions between flying and ground travel modes
Solution Approach 1:
The event detection conditions are made dynamic by automatically switching between ground travel conditions and flight conditions based on the mobile body's operational state. The control unit receives operational state information and dynamically adjusts which detection conditions are active, allowing the system to adapt to different modes without manual intervention or complex manual configuration
Solution Approach 2:
The system changes detection parameters based on operational mode. Different event detection thresholds and criteria are applied depending on whether the mobile body is in ground travel mode or flight mode. This parameter switching enables reliable event detection across diverse operational conditions while maintaining a unified detection framework
2Loss of information
If the dashboard camera records all video data continuously, then no event data is lost, but the loss of energy increases due to continuous recording
Solution Approach 1:
Instead of continuous recording, the system applies partial action by recording only when specific events are detected. The event detection unit monitors video data and triggers recording only when predefined events occur, such as unusual movements or detected threats, significantly reducing energy consumption while ensuring relevant event data is captured
Solution Approach 2:
The system uses feedback from the event detection unit to control the recording operation. The detection unit analyzes video data in real-time and provides feedback signals to the recording unit, which then activates or deactivates based on detected events. This feedback mechanism ensures event data is not lost while avoiding continuous recording
3Adaptability or versatility
If the dashboard camera uses multiple detection conditions for different modes, then the adaptability to various mobility states is improved, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions by both determining the operational state and managing the switching between detection conditions. This multi-functional design consolidates what could be separate systems into a single control unit, improving adaptability to different mobility states while avoiding the complexity of multiple independent control systems
Solution Approach 2:
The system performs preliminary action by pre-configuring multiple sets of detection conditions for different operational modes (ground travel, flight, transitions). When the operational state is determined, the corresponding pre-configured conditions are automatically activated, eliminating the need for real-time condition creation or complex runtime decision logic
