机载LiDAR数据是一种比较好的DEM生产的数据源,尽管生产流程基本成熟,但其中的一些关键技术还不能满足生产需求,需要在行业应用时加以深入研究。针对铁路勘察的具体特点和要求,提出了一种综合使用专业软件和多种航空摄影测量技术手段,满足铁路勘察设计需求的机载LiDAR数据生产DEM方法,并将其运用在生产实践中,大规模生产的结果表明,本流程和方法是可行的。 更多还原

【Abstract】 The airborne LiDAR data is a useful source of DEM production,although their production processes matured,but some of the key technologies can not meet the production needs.So,further study is needed in industry-oriented applications.For the specific characteristics and requirements of railway investigation,this paper proposed a DEM generation method of combining specialized software with a variety of aerial photogrammetry technology to meet the needs of the railway survey and design,and apply th... 更多还原
