【摘要】 本文将GIS技术与FTA方法结合起来,对旅游事故进行分类处理及定性定量分析,揭示原因并进行科学预测,利用OpenGL技术建立旅游事故可视化模型并进行矩阵变换,采用Dijkstra算法实现最佳脱险路径计算及Delaunay算法实现三角剖分。在VB平台上开发了安全旅游可视化系统,包括旅游事故树自动生成、事故定性定量分析、最佳脱险路径仿真及安全旅游评价等模块,并将系统进行测试、完善及推广。更多还原

【Abstract】 This paper integrates GIS with FTA, classifies the faults of tours, qualitatively analyzes and quantitatively analyzes them, builds the visualization model of touring accident with the OpenGL technology and carries out matrix alternation, adopts the Dijkstra algorithm to compute the best route out of danger and adopts the Delaunay algorithm to cut open the triangle. And developed safe tours visualization system on VB platform, including the module of voluntarily generating tours fault tree, the module of the quantita- tive analysis and quantitative analysis to faults, the module of simulating the best route out of danger and the module of estimating safe tour, etc, needing to test and perfect and spread the system.更多还原
