基于DEM的航摄设计方法

长期以来,航空摄影一直是获取基础地理信息的主要手段之一。航空摄影是一项多组织、多工序协调作业的综合性系统工程,不仅涉及飞行摄影,而且包括技术性很强的规划设计工作。本文针对当前国内航空摄影工作和规划设计的现状,在吸取国内外相关软件的先进理念和技术成果的基础上,通过分析地形起伏对像片重叠度的影响,对航空摄影工作的航线规划设计等核心技术内容展开讨论和研究,旨在研发一套能消除地形起伏对像片重叠度影响的航空摄影设计的原型系统。实验表明,该原型系统通过计算航带在实际地面的重叠度来精确调整基线,满足了重叠度的要求,较好地解决了地形起伏的问题,提高了航摄设计的效率,确保了航摄成果的质量。

Aerial Design Method Based on DEM

For a long time, aerial photography has been one of the primary means of obtaining the basic geographic data.Aerial pho-tography is a process involving multi-organizational coordination and comprehensive engineering jobs, not only flight photography, but also highly technical planning and design work.In this paper, in view of the current status of the domestic aviation photography planning and design work, on the basis of drawing on advanced theories of the related software and technology achievements at home and abroad, by analyzing the effects of topography on the overlap of the photograph, discuss the contents of the core technology and re-search of aerial photography planning and design work, the goal is to develop a prototype system of photograph aerial photography de-sign that can eliminate the impact of topography.Experiments show that the system can meet the requirements of the degree of overlap by precisely adjust the baseline with calculating the degree of overlap with the actual aircraft ground.This solves the problem of topog-raphy, improve the efficiency and ensure the quality of aerial photography products.
