摘要/Abstract

摘要： 全球化工产业的发展导致海上危化品泄漏事故频发,严重影响了海洋生态环境,如何开展快速、有效的应急响应已成为迫切需求。对泄漏危化品未来漂移扩散情况进行预测与可视化呈现是应急过程的一个重要环节,目前针对污染扩散可视化的相关研究在场景构建、渲染效率、可扩展性、交互控制等方面仍存在不足。该文提出了一种基于Unity3D引擎及其粒子系统的海上危化品漂移扩散过程三维动态可视化方法,在海洋周边三维场景构建和模型数据优化处理的基础上,通过粒子的动态更新实现了危化品扩散过程的可视化,并提供了针对场景漫游和扩散过程控制的交互接口。以杭州湾海域为例的模拟实验结果表明该方法的性能和效果满足实际应用需求,能够为海上危化品泄漏突发事故应急提供信息参考与辅助决策支持。

Abstract: The development of the global chemical industry has led to frequent leakage accidents of hazardous chemicals at sea, which has seriously affected the marine ecological environment. How to carry out rapid and effective emergency response has become an urgent need. The prediction and visualization of hazardous chemicals' future diffusion situation is an important part of the emergency process. At present, related researches on pollution diffusion visualization are still insufficient in the aspects of scene construction, rendering efficiency, scalability and interactive control. A three-dimensional dynamic visualization method for the diffusion process of marine hazardous chemicals based on the Unity3D engine and its particle system was proposed in this study. Based on the construction of three-dimensional scenes around the ocean and the optimization of model data, the visualization of hazardous chemicals diffusion process was achieved by dynamically updating the particles and interactive user interfaces for scene roaming and diffusion process control were provided. Taking Hangzhou Bay as an example, the simulation experiment results show that the performance and effect of this method meet the needs of practical applications. This method can provide information reference and auxiliary decision support for the emergency response of marine hazardous chemical leakage accidents.
