Object Stay Time Measurement in Multi-Area Surveillance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surveillance systems struggle to accurately measure the stay time of individuals within specific areas, particularly when they temporarily enter, exit, or pass through multiple areas, as they fail to associate the correct stay time with the relevant area.
Innovation Solution
An information processing apparatus is developed with a setting unit to define areas, a detection unit to analyze images, a determination unit to calculate stay time, and a specifying unit to associate the stay time with the correct area based on predetermined conditions, enabling accurate measurement and output of stay times for objects detected in multiple areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If areas are set for each predetermined location where people are helped, then the stay time measurement covers all relevant areas, but a person may be detected within multiple areas causing measurement inaccuracy
Solution Approach 1:
The patent segments the monitoring space into multiple distinct areas (first area, second area, etc.) and assigns different processing rules to each area. By dividing the overall monitoring task into area-specific detection and processing units, the system can track individuals across segmented zones while maintaining accurate stay time measurements for each specific area, resolving the contradiction between comprehensive coverage and measurement precision.
Solution Approach 2:
The patent introduces an intermediary processing unit that receives detection results from multiple areas and determines the appropriate area association for stay time measurement. This intermediary layer mediates between the multi-area detection system and the final stay time calculation, ensuring that even when individuals are detected in multiple areas, the correct stay time is attributed to the appropriate service area.
2Adaptability or versatility
If multiple areas are monitored simultaneously, then comprehensive coverage is achieved, but it becomes difficult to determine which area's stay time to measure for a single person
Solution Approach 1:
The patent applies local quality by assigning different functional characteristics to different areas. Each area is configured with specific detection parameters and processing rules appropriate to its function (e.g., reception area, waiting area, service area). This allows the system to maintain high measurement precision for each local area while simultaneously monitoring multiple areas, as each area's stay time is calculated based on its own specific criteria.
Solution Approach 2:
The patent implements dynamic area association where the designated area for stay time measurement can change based on the individual's movement and behavior patterns. The system dynamically determines which area should be associated with the stay time measurement based on real-time detection data, such as which area the person spent the most time in or which area is most relevant to their purpose, thereby maintaining measurement precision across dynamic multi-area scenarios.
