Rear Seat Passenger Detection Using Vehicle Camera System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a risk that drivers may forget about rear seat passengers, such as children or pets, when exiting a vehicle, especially if they are asleep or in a rear-facing car seat, leading to potential safety issues.
Innovation Solution
A computer-implemented method and system that uses a vehicle camera system to capture images of the rear seats, determines the presence of passengers, and provides alerts to the driver through a display screen or mobile device, ensuring the driver is aware of any passengers before exiting the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver relies on manual checking of rear seats, then the system complexity is low, but the reliability of detecting rear seat passengers is insufficient
Solution Approach 1:
The patent replaces manual mechanical checking with an automated camera-based detection system. The camera system captures images of the rear seat area, and image processing algorithms automatically detect the presence of passengers, substituting human visual inspection with automated optical detection and computational analysis.
Solution Approach 2:
The system enables self-service detection by having the camera system automatically monitor and detect passengers without requiring driver intervention. The image processing and passenger detection occur autonomously, with the system serving itself to provide continuous monitoring capability.
2Measurement precision
If continuous monitoring is implemented, then the detection precision is improved, but the energy consumption increases
Solution Approach 1:
The patent implements periodic monitoring by capturing images at specific intervals or under specific conditions (such as when the vehicle is parked or when motion is detected), rather than continuous monitoring. This approach maintains detection precision for critical moments while reducing overall energy consumption by keeping the camera and processing dormant during non-critical periods.
Solution Approach 2:
The system performs preliminary detection by capturing images in advance before the driver exits the vehicle. The camera system is activated to take pictures of the rear seat area, and processing occurs beforehand, so the driver receives alert information before leaving, ensuring safety without requiring continuous active monitoring.
3Measurement precision
If image processing is performed to determine passenger presence, then the detection accuracy is improved, but the processing time increases
Solution Approach 1:
The system performs image capture and processing in advance before the driver needs to exit the vehicle. Images are captured and analyzed beforehand, so the detection results are ready when needed, eliminating time delays at the moment of exit while maintaining accurate processing.
Solution Approach 2:
The system skips unnecessary processing steps by focusing image analysis specifically on the rear seat area rather than processing entire images. The detection algorithm is optimized to quickly identify relevant features in the captured images, rushing through the essential detection process while maintaining accuracy.

AI summary
A system and method for providing rear seat monitoring within a vehicle that include activating a vehicle camera system to capture images of at least one rear seat of the vehicle. The system and method also include determining if at least one rear seat passenger is located within the at least one rear seat of the vehicle and storing a detection indication data when the at least one rear seat passenger is determined to be located within the at least one rear seat of the vehicle. The system and method further include providing at least one type of alert based on analyzing the detection indication data and determining the location of the at least one rear seat passenger included within the detection indication data.
