Surveillance Camera Control for Disaster Visibility Under Changing Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disaster surveillance systems rely on predetermined imaging ranges of surveillance cameras that do not account for varying environmental conditions, leading to inaccuracies in capturing effective field of view for damage assessment.
Innovation Solution
A disaster information processing apparatus that adjusts the operation of surveillance cameras based on real-time or pre-stored effective field of view ranges tailored to environmental conditions, using a processor to control zoom and tilt settings for optimal damage situation analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the imaging range of the surveillance camera is determined based on camera performance under specific environmental conditions, then the device complexity is reduced and ease of operation is improved, but the measurement precision of the effective field of view deteriorates under varying environmental conditions
Solution Approach 1:
The surveillance camera system automatically monitors its own imaging quality and adjusts its field of view range based on detected environmental conditions (dust, smoke, weather) without requiring external intervention. The camera self-diagnoses when image quality deteriorates and autonomously expands its effective field of view range to compensate for environmental degradation.
Solution Approach 2:
The system dynamically changes the effective field of view range parameter based on environmental conditions. When environmental quality deteriorates (increased dust, smoke, or adverse weather), the system expands the field of view range beyond the standard manufacturer-specified range to ensure continuous effective monitoring coverage.
2Reliability
If the surveillance camera operates with a fixed imaging range determined by manufacturer specifications, then the ease of operation is improved and device complexity is reduced, but the reliability of damage assessment deteriorates under varying environmental conditions
Solution Approach 1:
The surveillance camera transitions from a static fixed field of view to a dynamic adjustable field of view system. The effective range automatically adapts its parameters in response to real-time environmental conditions, allowing the camera to maintain reliable damage assessment capability across varying weather, dust, and smoke conditions without requiring manual reconfiguration.
3Measurement precision
If the effective field of view range is expanded to account for environmental conditions, then the measurement precision improves, but the device complexity increases due to additional monitoring and control mechanisms
Solution Approach 1:
The surveillance camera system performs multiple functions using the same hardware components: it simultaneously captures images for damage assessment, monitors environmental conditions (dust density, smoke concentration, weather effects), and automatically adjusts its effective field of view range. This multi-functionality eliminates the need for separate dedicated environmental monitoring devices, reducing overall system complexity while maintaining enhanced measurement precision.

AI summary
Provided are a disaster information processing apparatus, an operation method of a disaster information processing apparatus, an operation program of a disaster information processing apparatus, and a disaster information processing system capable of controlling an operation of a surveillance camera suitable for an environmental condition of a disaster-stricken area. An effective field of view range derivation unit derives and acquires an effective field of view range in a bird's-eye view image of an area captured by a surveillance camera, and a damage situation of the area being able to be grasped in the effective field of view range, and the effective field of view range changing depending on an environmental condition of the area. A control signal generation unit generates a control signal of the surveillance camera corresponding to the effective field of view range. An operation of the surveillance camera is controlled by the control signal.
