摘要
地震灾害发生后,为实现生命体的快速发现和科学救援,需要多源数据的辅助支撑.遥感数据、现场环境数据、危险设施分布数据、生命体征数据、生命探测设备运行状态数据以及历史数据,共同构成了应急救援场景下的多源异构数据集.本文面向应急救援领域的数据统一监管、多维分析等应用需求,深入研究多源异构数据的三维空间融合分析技术,提出了一种基于WebGL渲染技术的无插件三维空间融合方案,研制应急救援数据融合可视化系统,实现统一时空框架下应急救援场景所需多源异构数据的融合表达,辅助作业人员进行联动态势分析,帮助指挥人员进行指挥决策,大幅提高应急救援现场应用的工作时效.
In order to realize rapid discovery and scientific rescue of life after earthquake disaster,multi-source data is needed.Remote sensing data,scene environment data,distribution data of dangerous facilities,life signs data acquired by life detection equipment,status data of life detection equipment,and historical data constitute multi-source heterogeneous data sets in emergency rescue scenarios.Aiming at the application requirements of unified data supervision and multidimensional analysis in the field of emergency rescue,this work deeply studies the three-dimensional spatial fusion analysis technology of multi-source heterogeneous data,proposes a plug-in-free three-dimensional spatial fusion scheme based on WebGL rendering technology,and develops a visualization system of emergency rescue data fusion.Fusion and expression of multi-source heterogeneous data needed in emergency rescue scenarios can be realized under the unified space-time framework.It can assist operators to conduct joint dynamic potential analysis,help commanders to make command decisions,and greatly improve the efficiency of emergency rescue field applications.
