Surveillance System Stranger Detection via Feature Value Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a risk of harm to individuals from strangers, particularly in areas outside of their living space, or from stalkers approaching without being noticed within their living area.
Innovation Solution
A surveillance system that includes cameras, an image processing apparatus, and a surveillance apparatus. The surveillance apparatus features a feature value storage unit, a detection unit, and an output unit. It associates and stores feature values of watched targets, detects approaches of unfamiliar individuals within a reference distance by processing captured images, and performs predetermined outputs based on detection results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a surveillance system uses image processing to detect approaching strangers, then personal security is improved, but device complexity increases
Solution Approach 1:
The surveillance system is divided into distinct functional modules: a feature value storage unit that stores reference data, a detection unit that processes images and identifies strangers, and an output unit that generates alerts. This segmentation allows each component to perform its specific function efficiently while reducing overall system complexity through modular design.
Solution Approach 2:
The patent introduces an image processing apparatus as an intermediary component between the camera and the surveillance apparatus. This intermediary handles the complex image processing and feature extraction tasks, allowing the core surveillance system to remain relatively simple while still achieving high reliability through the specialized processing capabilities of the intermediary component.
2Area of stationary object
If the surveillance system monitors a larger area with multiple cameras, then coverage is improved, but device complexity increases
Solution Approach 1:
The surveillance apparatus is designed with universal functionality that can handle multiple camera inputs and process images from various locations. The feature value storage unit and detection unit can operate with a single camera or multiple cameras without requiring fundamental changes to the system architecture, allowing expanded coverage while maintaining manageable complexity through the multi-functional design.

AI summary
A surveillance apparatus (100) includes a feature value storage apparatus (200) that associates and stores a feature value of a person belonging to the same group, a detection unit (102) that detects an approach of a person not belonging to the same group to the person belonging to the same group within a reference distance by processing a captured image by using the feature value, and an output unit (104) that performs a predetermined output by using a detection result of the detection unit (102).
