面向位置态势系统的纸地图增强现实表达方法研究

Research on Expression Method of Augmented Reality Paper Map for Position Situation System

位置态势系统对地图上的态势信息表达提出了特殊要求。应用增强现实技术将位置态势配准到纸地图上,可突破纸地图平面、静态的表现形式,并支持从整体到局部的视觉认知过程。针对纸地图难以表现立体模型和动态目标的问题,首先结合位置态势监控的应用场景分析了纸地图增强现实的处理过程和虚实融合的数学基础;然后从虚实融合的角度,对纸地图增强现实的虚实关系、表达内容、表达形式和表达方法进行了深入探讨;最后针对位置态势监控的应用需求,构建了虚实融合的位置态势感知环境。实验表明,顾及虚实场景关系的纸地图增强现实在位置态势表达上具有更好的虚实融合效果。

Special requirements for situation information expression on maps are put forward by position situation system.The two-dimensional and static expression way of paper map is greatly changed by the application of AR technology to register position situation on the map,which makes the visual cognitive process from the whole to the parts possible.Aiming at the problem that paper map was difficult to express three-dimensional models and dynamic targets,the processing flow of AR based on paper map and the mathematical basis of virtual reality fusion are analyzed at first,combined with the application scene of position situation monitoring.Then,the relationship between virtual reality and real reality,the expression content,form and method of AR based on paper map are discussed from the perspective of virtual reality fusion.Finally,a position situational awareness environment based on virtual reality fusion is constructed in order to meet the application requirements of monitoring.The results show that the AR based on paper map considering the relationship between virtual and real scenes proves to be better at the expression of position situation.
