倾斜摄影测量的城市战场环境三维建模及可视化

Research on 3D Modeling and Visualization ff Urban Battlefield Environment Based on Oblique Photogrammetry

城市是进行特种作战、爆发恐怖活动和突发性事件并影响地区稳定的重要地域,信息化时代的今天,以无人机倾斜摄影测量为代表的新测绘技术突飞猛进,为建立实景三维城市战场带来契机,从城市战场环境作战需求出发,介绍了无人机倾斜摄影测量技术和城市战场实景三维建模流程,基于Context Capture获得了逼真、高精度的城市三维模型,结合LocaSpace Viewer实现了城市战场要素标绘、量测、通视、可视域、雷达等可视化分析,实验成果证明了方法可行性和有效性,突破了传统二维地图的视觉和量测上的局限,为指挥员分析利用地形、指挥决策提供重要参考。

City is an important area for special operations,terrorist activities and emergencies,which affect the stability of the region.At the present information age,the new surveying and mapping technology represented by UAV oblique photogrammetry is advancing rapidly,which brings opportunities for the establishment of real 3D urban battlefield.Based on the operational requirements of urban battlefield environment,introduces UAV oblique photogrammetry technology and 3D modeling flow of real urban battlefield are introduced.Based on context capture,a realistic and high-precision 3D city model is obtained,which is combined with LocaspaceViewer the visualization analysis of plotting,measurement,inter visibility,viewshed,radar,and others of elements of unban battlefield.The experimental results prove the feasibility and effectiveness of the method.The method breaks through the limitations of vision and measurement of traditional two-dimensional maps,and provides important references for commanders to analyze and utilize terrain and to make command decisions.
