3D Visualization System for Complex Hazard Evacuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality (AR), mixed reality (MR), and extended reality (XR) technologies lack effective implementation for early evacuation and response to complex hazardous situations, particularly for colorless and odorless dangerous particulates, as they fail to provide intuitive and immediate 3D visualization of hazards and evacuation routes.
Innovation Solution
A 3D visualization system that includes a central server system for generating a 3D extended reality environment by processing 3D map and hazard information, using a digital twin generator and graphic information processor, and a visualization terminal for real-time output and interaction, enabling intuitive visualization and sharing of hazard information, evacuation routes, and auxiliary data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If AR/MR/XR technologies are used for hazard visualization, then intuitive 3D visualization of hazards is improved, but the ability to effectively implement early evacuation and response to complex hazardous situations remains insufficient
Solution Approach 1:
The patent transitions from traditional 2D hazard map displays to immersive 3D virtual reality environments, allowing users to visually navigate and understand hazard locations, evacuation routes, and safe zones in three-dimensional space. This dimensional enhancement provides intuitive spatial awareness that directly addresses the insufficiency of conventional visualization methods for emergency response
Solution Approach 2:
The system introduces a centralized server as an intermediary that collects, processes, and integrates multi-source hazard information (sensor data, map data, weather data) and distributes it to multiple user terminals. This intermediary architecture enables coordinated evacuation guidance and real-time situation sharing among multiple users, directly improving evacuation effectiveness
2Adaptability or versatility
If multiple hazard information types are integrated, then comprehensive hazard coverage is improved, but system complexity increases
Solution Approach 1:
The centralized server architecture serves multiple functions: collecting data from diverse sensors, processing hazard information, generating 3D virtual environments, providing evacuation guidance, and enabling real-time communication. This multi-functional design consolidates complexity into a single coordinating system while maintaining comprehensive hazard coverage across multiple information types
Solution Approach 2:
The centralized server acts as an intermediary that standardizes and integrates diverse hazard information sources (fine dust sensors, chemical sensors, biological sensors, radiological sensors, weather data) into a unified processing framework. This intermediary layer manages the complexity of multi-source integration while providing comprehensive hazard coverage through standardized data handling
3Loss of time
If real-time 3D environment generation is implemented, then immediate hazard information delivery is improved, but processing requirements increase
Solution Approach 1:
The system pre-generates 3D map information and virtual environment frameworks before emergencies occur, storing processed geographic and spatial data in advance. During actual emergencies, the centralized server only needs to overlay real-time hazard data onto pre-prepared 3D environments, significantly reducing processing time and power requirements while maintaining immediate information delivery
