Passenger Posture Monitoring by Seat Position in Autonomous Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current passenger monitoring systems for means of transportation, such as buses, lack an effective method to ensure passenger safety by accurately monitoring passenger postures and positions, especially in self-driving or remotely operated vehicles where human oversight is limited.
Innovation Solution
A passenger monitoring apparatus and method that includes an image acquiring unit, a posture identifying unit, and a determining unit to analyze image data from cameras on vehicles, identifying passenger postures and positions, and determining if they match predetermined safe posture patterns, with the ability to output warnings for anomalous states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional monitoring systems are used, then the system structure is simple, but the monitoring precision and safety detection capability are insufficient
Solution Approach 1:
The monitoring system is divided into multiple functional modules: image acquiring unit, posture identifying unit, position identifying unit, and determining unit. Each module performs a specific function (capturing images, analyzing postures, locating passengers, and making safety determinations), which improves monitoring precision while keeping the overall system structure organized and manageable despite the increased complexity.
Solution Approach 2:
The patent introduces a determining unit as an intermediary that compares identified postures and positions against predetermined safety patterns. This intermediary layer enables sophisticated safety analysis without requiring the entire system to be fundamentally redesigned, thus improving monitoring capability while managing complexity through modular addition.
2Reliability
If comprehensive passenger monitoring is implemented, then passenger safety is improved, but the complexity of the monitoring system increases
Solution Approach 1:
The system establishes predetermined posture patterns and safety criteria in advance before actual monitoring begins. These pre-defined patterns serve as reference standards that the real-time monitoring system compares against, enabling comprehensive safety monitoring without requiring complex real-time decision-making algorithms, thus improving reliability while managing complexity.
Solution Approach 2:
The determining unit continuously compares actual passenger postures and positions against predetermined safety patterns, providing feedback on safety status. This feedback mechanism enables the system to maintain high reliability through continuous verification while keeping the system structure relatively simple by using direct comparison logic rather than complex adaptive algorithms.
