In-Vehicle Camera Control for Passenger Exit Direction Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no technology that allows a driver to monitor the movements of a passenger who has exited a vehicle while the driver is temporarily away, potentially leading to the passenger leaving without the driver's knowledge.
Innovation Solution
A recording system with a camera that captures 360-degree images, including inside and outside the vehicle, which detects the driver and passenger using dedicated units, determines if the passenger has exited, and records the outside scene when the driver is no longer present, allowing the driver to review the passenger's exit movements later.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a camera is used to monitor the vehicle interior, then the driver can observe the passenger, but the driver cannot find out the passenger's movements when the driver temporarily gets out of the vehicle
Solution Approach 1:
The system activates recording in advance when the driver exits the vehicle, before the passenger potentially exits. The recording control unit starts capturing exterior images when driver absence is detected, ensuring the passenger's movements are recorded before the event occurs. This preliminary action ensures no movement information is lost.
Solution Approach 2:
The recording system automatically detects driver absence and passenger exit events, and autonomously activates recording without requiring driver intervention. The system serves itself by using sensors and detection units to monitor conditions and trigger recording automatically, eliminating the need for manual operation while ensuring continuous monitoring.
2Loss of information
If the camera continuously records both inside and outside the vehicle, then all passenger movements are captured, but energy consumption and data storage requirements increase
Solution Approach 1:
Instead of continuous recording, the system uses periodic detection cycles to monitor driver presence and passenger status. The recording control unit activates the camera only during specific periods when driver absence is detected and passenger exit is confirmed, creating a periodic on-demand recording pattern that reduces energy consumption while capturing all necessary events.
Solution Approach 2:
The system performs preliminary detection of driver absence using sensors before activating the camera for recording. This preliminary action allows the system to prepare for potential passenger exit events without continuously recording, activating the camera only when needed based on pre-detected conditions, thereby reducing unnecessary energy consumption.
3Loss of information
If the system records only when the driver is absent, then passenger movements are captured, but the system cannot distinguish between intentional and unintentional passenger exits
Solution Approach 1:
The system uses feedback from multiple detection units including weight sensors, door sensors, and camera image analysis to determine passenger exit events. The recording control unit receives feedback from these sensors and cross-references their signals to accurately detect when a passenger has exited, providing comprehensive information about the exit event for later review by the driver.
Data Source
AI summary
A recording system includes a shooting data acquisition unit, a passenger detection unit, a driver detection unit, a determination unit, and a recording control unit. The shooting data acquisition unit acquires shooting data from a camera for taking an image of inside/outside of a vehicle in which a driver and a passenger ride. The passenger detection unit detects at least the passenger. The driver detection unit detects the driver in a predetermined range. The determination unit determines whether the passenger inside the vehicle has gotten out thereof. The recording control unit instructs, after the driver detection unit no longer detects the driver detected until then, when the determination unit determines that the passenger has gotten out of the vehicle, a recording device to record the shooting data of the outside thereof.
