摘　　要：针对传统室内地标提取方法在地震应急情境下的局限性,该文以大型城市综合体地震情境为例,提出一种室内应急疏散指示地标综合显著度评价模型,分别提取面向男性和女性用户的室内应急疏散指示地标。基于情境显著度、视觉显著度、用户属性显著度和空间显著度4个一级指标建立室内应急疏散指示地标显著度评价指标体系;采用AHP-CRITIC-ICM组合赋权法确定地标显著度评价指标权重,构建室内应急疏散指示地标综合显著度评价模型;利用地标综合显著度差异分层级提取地标。基于VR场景的实验结果表明:模型提取结果准确率达81.46%,明显高于传统模型,能够在大型室内环境应急疏散过程中为用户提供关键信息,对室内应急疏散导航地图设计具有重要的实际意义。Indoor landmarks play a crucial role during the process of evacuation because of their significant guiding functions.Addressing the limitations of traditional indoor landmark extraction methods in emergencies,a comprehensive significance evaluation model of indoor landmarks is proposed in this paper,using a seismic scenario in large urban complex as an example.Firstly,a significance evaluation index system for indoor landmarks is established based on four primary indicators:contextual significance,visual significance,user attribute significance,and spatial significance.Secondly,the AHP-CRITIC-ICM combined weighting method is employed to determine the weights of the indicators respectively and then construct the comprehensive significance evaluation model.Subsequently,indoor landmarks are extracted hierarchically according to their comprehensive significance.Experimental results in VR scenarios demonstrate that the extraction accuracy of the model reaches 8l.46%,which is better than that of traditional models.The model can provide critical information for users in large indoor emergency evacuations.It has important practical significance for indoor evacuation map design.
