Vehicle Camera Recording for Unnoticed Passenger Exit Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to enable drivers to monitor the movements of passengers who unintentionally exit a vehicle while the driver is away.
Innovation Solution
A recording system with a 360-degree camera, passenger and driver detection units, and a determination unit to record exterior footage when the driver is no longer detected, capturing the passenger's movements upon exit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a camera and display are activated to show images before occupants exit the vehicle, then the driver can see the interior, but the driver cannot monitor passenger movements after exiting
Solution Approach 1:
The system performs preliminary detection of passenger presence and exit status before recording exterior footage. The determination unit checks whether the passenger has exited based on detection unit data, and only then activates recording of exterior shots, avoiding continuous recording and reducing system complexity while ensuring movement information is captured
Solution Approach 2:
The system uses detection units to create a digital representation of passenger presence and movement status, then uses this copied information to control recording actions. This allows the system to monitor passenger movements indirectly through detection data rather than requiring direct continuous visual monitoring
2Loss of information
If exterior footage is recorded continuously to capture passenger movements, then complete movement information is obtained, but energy consumption and data storage requirements increase
Solution Approach 1:
Instead of continuous recording, the system performs periodic checks using detection units to determine passenger exit status, and activates exterior recording only when a status change is detected. This periodic monitoring approach captures necessary movement information while significantly reducing camera energy consumption compared to continuous operation
Solution Approach 2:
The system uses detection units to provide feedback on passenger presence and exit status, which then controls whether exterior recording should be activated. This feedback mechanism ensures recording occurs only when necessary to capture movement information, optimizing energy usage while maintaining information completeness

AI summary
A recording system (10) includes a shooting data acquisition unit (120), a passenger detection unit (129), a driver detection unit (130), a determination unit (131), and a recording control unit (123). The shooting data acquisition unit (120) is configured to acquire shooting data from a camera configured to take an image of an inside and an outside of a vehicle in which a driver and a passenger ride. The passenger detection unit (129) is configured to detect at least the passenger from the shooting data. The driver detection unit (130) is configured to detect the driver present in a predetermined range. The determination unit (131) is configured to determine whether or not the passenger present inside the vehicle has gotten out of the vehicle. The recording control unit (123) is configured to instruct, after the driver detection unit no longer detects the driver whom it had detected until then, when the determination unit (131) determines that the passenger has gotten out of the vehicle, a recording device to record the shooting data of the outside of the vehicle.
