摘要
无人机航空摄影测量技术是继传统航空摄影技术之后一种新型的数字航空测量技术,相对于传统的航空摄影测量具有更强的普适性和便捷性。快速有效且流程化地制作大比例尺DOM是当前摄影测量工程方面研究的热点问题,因此,文中借助PhotoScan软件设计流程化方法快速制作大比例尺DOM,重点讨论了制作大比例尺DOM过程中外业数据获取、内业数据处理应该注意的几个关键问题,并通过对实验过程与结果论证分析表明,实验中采用的流程化处理方法对大比例尺DOM制作的作业效率、作业时间等方面有很大提高,且制作精度达到了国家1:2 000 DOM精度要求。该方法在测绘应急保障与紧急决策服务方面具有一定的参考价值。
Unmanned aerial vehicle （UAV） photogrammetry technology was a new digital aerial surveying technology after the traditional aerial photography technology, which had better universality and convenience compared with traditional aerial photogrammetry. Due to the rapid and effective process of large - scale DOM production were a hot issue in the field of photogrammetry, a workflow method to quickly produce large - scale DOM using the PhotoScan software was designed. Meantime, The key issues in the process of data acquisition and data processing of the large - scale DOM production were discussed. Through the analysis of the experimental process and results, the workflow method had greatly improved the production efficiency and operating time of producing the large - scale DOM, and the precision of production reached the national 1：2 000 DOM accuracy requirements. The method had certain reference value in the surveying and mapping emergency support and emergency decision -making services.
