Dynamic Analysis Period Adjustment for Vehicle Passenger Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for analyzing information inside vehicles incur high costs due to unnecessary calculations and uniform analysis periods, leading to inefficient resource usage and increased costs when analysis is not needed.
Innovation Solution
An analysis processing device that adjusts the analysis period based on the seated and standing positions of passengers, using a calculation unit to determine the analysis period through a function that changes frequency of analysis according to passenger positions, thereby reducing unnecessary analysis and costs.

Engineering Contradiction Analysis
1Reliability
If a uniform analysis period is used for all situations inside the vehicle, then the analysis system maintains consistent monitoring capability, but unnecessary calculations and costs increase when analysis is not needed
Solution Approach 1:
The analysis period is changed from a fixed uniform value to a dynamic value that adapts based on detected situations inside the vehicle. The period determination unit adjusts the analysis period according to situation data, making the monitoring system flexible and responsive to actual conditions rather than operating with a static configuration.
Solution Approach 2:
The system changes the parameter of analysis period based on detected situations. When high-risk situations are detected, the analysis period is shortened to increase monitoring frequency; when low-risk situations are detected, the analysis period is extended to reduce unnecessary calculations and energy consumption.
2Measurement precision
If image recognition and analysis are performed continuously, then detection precision is maintained, but calculation costs and power consumption increase significantly
Solution Approach 1:
Instead of continuous analysis, the system performs image recognition and analysis periodically based on the determined analysis period. The period varies dynamically according to the detected situation, allowing the system to maintain detection precision when needed while reducing power consumption during low-risk periods through intermittent analysis rather than continuous operation.
3Reliability
If the analysis period is shortened to increase monitoring frequency, then detection reliability improves, but calculation resources and costs increase
Solution Approach 1:
The system dynamically changes the analysis period parameter based on detected situations. During high-risk situations, the analysis period is shortened to improve detection reliability; during low-risk situations, the analysis period is extended to improve calculation efficiency and reduce resource consumption, thereby optimizing the trade-off between reliability and productivity.
