In-Vehicle Passenger Movement Detection Under Crowded Standing Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in accurately detecting passenger movement within vehicles, particularly when there are many standing passengers, leading to increased false positives and unnecessary in-vehicle announcements.
Innovation Solution
An information processing apparatus that determines the number of standing passengers and adjusts the detection process and announcement strategy based on this count, suppressing announcements in situations where false detection is likely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detection process is executed continuously to monitor passenger movement, then the reliability of safety monitoring is improved, but false detection increases when there are many standing passengers
Solution Approach 1:
The system changes the operational parameter of the detection process by determining whether to execute it based on the number of standing passengers. When the number of standing passengers exceeds a threshold, the detection process is suppressed to avoid false detections. This dynamic parameter adjustment resolves the contradiction by adapting the detection execution state to the current passenger conditions.
2Measurement precision
If the detection process is suppressed when there are many standing passengers, then false detection is reduced, but safety monitoring coverage is decreased
Solution Approach 1:
The system dynamically changes the execution parameter of the detection process based on the standing passenger count. By suppressing detection only when standing passengers exceed a threshold, the system maintains detection precision while preserving safety monitoring reliability in other conditions. This selective parameter change resolves the contradiction by balancing precision and reliability based on actual conditions.
3Reliability
If in-vehicle announcements are made for every detected movement, then passenger safety awareness is improved, but unnecessary announcements increase causing passenger anxiety
Solution Approach 1:
The system changes the announcement output parameter by suppressing announcements when the detection process is suppressed due to high standing passenger counts. This prevents unnecessary announcements that would cause passenger anxiety while maintaining safety awareness announcements when detection is reliable. The conditional parameter change resolves the contradiction between safety awareness and passenger comfort.

AI summary
A controller includes at least one processor of an information processing apparatus acquires a number of standing passengers in a vehicle. The controller of the information processing apparatus determines whether to execute the detection process of passengers moving inside the vehicle based on analysis of a moving image capturing the inside of the vehicle according to the number of standing passengers. Then, the controller outputs announcement information for making an in-vehicle announcement regarding movement inside the vehicle when the detection process detects a standing passenger moving inside the vehicle.
