设计与开发大规模倾斜影像数据管理工具

Design and Development of Massive Oblique Imagery Management Tools

多角度倾斜相机已经成为三维数字城市建设的主要数据获取手段。针对倾斜摄影测量特点,面向海量影像集成处理需求,综合考虑相机成像模型以及影像关联关系,设计与实现了一种大规模倾斜影像数据管理工具,提供了工程管理信息存储、倾斜影像分组浏览、地面覆盖范围计算、目标快速检索等功能。应用实验证明该管理工具能够满足倾斜摄影测量工程管理的实际需求,有效提高了多模式海量影像数据的检索效率。

Oblique camera has been widely used in 3D reconstruction of city models as the main way to collect the data.For the ＂Maltese Cross＂ configuration,a typical oblique camera system holds five cameras bundled in a fixed platform and took images from five different angles.Except for larger coverage obtained by the five cameras,the primary merits of this system is the abundant facades information of the buildings.However,existing software system can not satisfy the requirement of automation and massive data management.In this paper,a massive oblique imagery management tools are proposed and developed,which aims at organizing and storing information,e.g.project management,browsing images,calculating ground coverage and fast retrieval of objects.Large oblique imagery datasets are employed for the experimental analysis.The results proved that the designed tools can satisfy the requirements of oblique imagery management,and substantially enhance efficiency of image retrieval by multi-mode.
