Surveillance System with Mobile Identification Unit for Distant Event Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surveillance cameras with fixed positions struggle to capture detailed images of events occurring at distances due to limited viewing angles and resolution, making it difficult to obtain clear images of distant or small-scale events.
Innovation Solution
A surveillance method that analyzes event images from a first image sensor, moves an identification unit with a second image sensor to the event location based on analysis, and coordinates with multiple monitoring devices to enhance image capture, using directional sensors and light-emitting units for navigation and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If surveillance cameras are fixed on structures to provide stable monitoring, then device stability is improved, but the ability to capture detailed images of distant events deteriorates
Solution Approach 1:
The surveillance system is divided into two functional units: a fixed surveillance camera for stable monitoring and a mobile identification unit (drone) for detailed image capture. This segmentation allows each component to perform its specialized function - the fixed camera provides stability while the mobile unit provides close-up detailed imaging when needed
Solution Approach 2:
The system transitions from a purely static surveillance setup to a dynamic hybrid system. The identification unit can move dynamically to optimal positions to capture detailed images of events, while the fixed surveillance camera maintains stable overall monitoring. This dynamic capability resolves the contradiction by allowing the system to adapt its configuration based on operational needs
2Ease of manufacture
If surveillance cameras are positioned at fixed locations, then installation complexity is reduced, but the coverage area and event detection capability deteriorate
Solution Approach 1:
The monitoring function is segmented between the fixed surveillance camera that provides broad area coverage and the mobile identification unit that can dynamically extend coverage to distant or specific areas of interest. This allows the system to maintain simple fixed installation while achieving expanded effective coverage
Solution Approach 2:
The system adds a mobile dimension to the traditionally fixed surveillance model. The identification unit operates in three-dimensional space, allowing it to access areas that fixed cameras cannot reach and provide coverage in dimensions beyond the horizontal plane, effectively expanding the monitoring coverage area
3Device complexity
If fixed surveillance cameras are used, then system complexity is minimized, but the ability to obtain detailed images of small-scale events deteriorates
Solution Approach 1:
The system segments the imaging function into two levels: the fixed surveillance camera captures overall scene information with simple system architecture, while the mobile identification unit is deployed specifically for detailed imaging of small-scale events. This segmentation maintains low overall system complexity while enabling high-detail capture when needed
Solution Approach 2:
Instead of making the entire surveillance system complex and mobile, only the identification unit required for detailed imaging is made mobile. The majority of the system remains simple and fixed, performing partial surveillance functions. The mobile unit is deployed selectively for excessive action - capturing detailed images beyond what the fixed camera can provide
