Video Analysis Apparatus for Person Characterization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surveillance systems face determination errors when assessing individuals based solely on continuous presence or reappearance frequency, often misidentifying individuals who are not suspicious, such as workers within a surveillance range.
Innovation Solution
An analysis apparatus that extracts individuals from video data, calculates continuous appearance time periods and reappearance intervals, and infers characteristics using these metrics to provide a more accurate assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If determination is made based solely on continuous presence time or reappearance frequency, then the detection process is simple, but determination errors increase and reliability decreases
Solution Approach 1:
The patent segments the determination process into multiple independent criteria: continuous presence time, reappearance frequency, and behavioral pattern analysis. Each criterion is evaluated separately and then integrated to form a comprehensive determination, reducing errors while maintaining manageable complexity through modular assessment
Solution Approach 2:
The patent transitions from single-dimension determination (only time or frequency) to multi-dimensional determination by adding behavioral pattern analysis as a new dimension. This allows the system to evaluate persons from multiple angles simultaneously, improving reliability without proportionally increasing complexity
2Measurement precision
If multiple determination criteria are used, then determination accuracy improves, but the complexity of the determination process increases
Solution Approach 1:
The complex determination process is segmented into distinct analytical modules: time calculation unit for continuous presence, frequency analysis unit for reappearance patterns, and behavioral pattern recognition unit. Each module handles a specific aspect independently, making the overall complex process more manageable and maintainable
Solution Approach 2:
The patent creates a universal determination framework that can handle multiple types of criteria (time-based, frequency-based, behavior-based) through a single integrated system. This multi-functional approach allows accurate person characterization without requiring separate specialized systems for each criterion type

AI summary
Provided is an analysis apparatus (10) including a person extraction unit (11) that analyzes video data to extract a person, a time calculation unit (12) that calculates a continuous appearance time period for which the extracted person has been continuously present in a predetermined area and a reappearance time interval until the extracted person reappears in the predetermined area for each extracted person, and an inference unit (13) that infers a characteristic of the extracted person on the basis of the continuous appearance time period and the reappearance time interval.
