【摘要】：近年来随着我国经济建设的高速发展,各类安全生产事故发生的次数也相应的不断增长。安全事故的频发对人们的生命财产安全构成了极大地威胁,给人们的生产和生活带来了较多的不便。计算机技术的引入提高了人们对事故数据的分析处理能力,但是目前三维GIS技术在安全事故态势三维可视化方面的应用研究较少。本文基于已经提取出的官方公布的多年安全事故数据,并结合地理信息数据,研究并实现了安全事故态势三维可视化系统。为满足不同类型用户的需求,该系统包括基于OSG Earth安全事故数据三维可视化管理子系统和基于浏览器的安全事故数据采集与三维展示子系统。基于OSG Earth安全事故数据三维可视化管理子系统主要针对管理员用户,通过该子系统可以对事故数据进行较为全面的浏览展示、数据管理、分析等。该子系统在本地计算机中运行,通过加载不同三维模型和矢量数据,对事故数据进行不同类型的展示和管理。主要实现技术包括Open Scene Graph三维渲染引擎、OSG Earth、3D Studio MAX建模工具。基于浏览器的安全事故数据采集与三维展示子系统主要针对普通用户,通过该子系统可以完成事故数据的录入、查询、修改和事故数据三维展示等操作。该子系统采用B/S架构,主要对事故的统计信息进行相关的三维可视化展示,普通用户使用浏览器即可完成相应的操作。主要实现技术包括HTML5 Canvas、百度ECharts-X组件。本文的研究目的是在搜集安全事故数据并提取出有用信息的基础上,结合OSG Earth和HTML5 Canvas相关技术,实现基于本地应用和浏览器的安全事故数据三维可视化系统,通过在三维地球上为不同类型事故数据加载不同模型,以及结合二维图表展示事故统计信息等其他不同的建模和展示方式,从而将事故数据信息变得更加清晰、直观,对比更加明显,能够较好地为预防安全生产事故提供基础性决策依据。
[Abstract]:In recent years, with the rapid development of economic construction in China, the number of accidents in production safety has been increasing.The frequent occurrence of safety accidents poses a great threat to the safety of people's life and property, and brings more inconvenience to people's production and life.The introduction of computer technology has improved the ability of analyzing and processing accident data, but the application of 3D GIS technology in 3D visualization of safety accident situation is less.In this paper, a 3D visualization system for the situation of safety accidents is studied and implemented based on the official published data of safety accidents and geographic information data.In order to meet the needs of different types of users, the system includes three dimensional visual management subsystem based on OSG Earth security incident data and a subsystem based on browser to collect and display security incident data.The 3D visual management subsystem of safety accident data based on OSG Earth is mainly aimed at administrator users. Through this subsystem, the accident data can be browsed and displayed, data management, analysis and so on.The subsystem runs in a local computer and displays and manages the accident data of different types by loading different 3D models and vector data.The main implementation technologies include Open Scene Graph 3D rendering engine, OSG EarthCraft 3D Studio MAX modeling tool.The browser-based safety incident data collection and 3D display subsystem is mainly aimed at ordinary users, through which the operation of incident data input, query, modification and 3D display of accident data can be completed.This subsystem adopts the B / S architecture, mainly carries on the related three-dimensional visualization display to the accident statistical information, the ordinary user can complete the corresponding operation using the browser.The main implementation technologies include HTML5 canvas, Baidu ECharts-X components.The purpose of this paper is to realize the 3D visualization system of safety incident data based on local application and browser, based on the collection of safety incident data and the extraction of useful information, combined with OSG Earth and HTML5 Canvas technology.By loading different models on 3D Earth for different types of accident data, and combining with two-dimensional charts to display statistical information of accidents, and other different modeling and presentation methods, the accident data information becomes clearer and more intuitive.The comparison is more obvious and can provide the basic decision basis for the prevention of production safety accidents.
