面向火灾动态疏散的三维建筑信息模型

3dbuilding information model for  facilitating dynamic analysis  of  indoor fire emergenc y

  • 摘要: 基于三维建筑空间表达充分结合建筑防火专题语义信息建立了面向建筑物内部空间划分与通达性分析的一体化语义描述并结合防火部件层次的动态特征发展面向室内火灾动态疏散过程的三维建筑信息模型从而辅助火灾应急疏散的三维空间逃生分析 基于实验构建的三维建筑信息模型及其基于语义的动态联通网络证明了其在室内火灾动态疏散中的特殊价值

     

    Abstract: a vge-basedbimifc information-supported and semantic  anal ysis  oriented 3dbuildinginformation model  is  proposed  for  facilitating indoor  fire  emergency evacuation.by taking the dynamic thenfeature  points  are  extracted by using improved harris al gorithm ei ghbor  information  aroundthese points  is  described using color  invariant  value as  input  information.finall ythe points  betweentwo images  are matched using correlation coefficient.to demonstrate  the  feasibilit y of  approachex-periments with groups of  street  view  imagescompared with the  traditional  sift al gorithm.show thatthe proposed al gorithm can not onl y intensive match pointshi gher matching correct  rate  speed validity.
