摘　　要：无人机获取影像数据具有灵活性高、时效性强、分辨率高、成本低等优点,在应急救灾、密林区及无人区变化监测方面发挥了越来越多的作用。本文结合生产实践,提出基于无人机影像的密林区域DOM制作方法,即利用Pix4Dmapper软件的一体化处理模式高效处理密林区域无人机数据,利用EPT软件进行正射影像编辑。实践结果表明,Pix4Dmapper软件无需人工干预即可高效完成无人机航摄产品的生产,后期成果采用EPT软件进行处理,可得到满足相关规范要求的密林区域DOM成果。该方法可实现软件之间的强强联合,降低作业难度,提高工作效率。Due to the advantages of high flexibility,high timeliness,high resolution and low cost with UAV image data,it has played more and more important role in disaster reliefs and monitoring in forestor depopulated area.According to the actual production practice,this paper proposes a method of DOM production of dense forest area based on UAV image.This method processes UAV data of dense forest area efficiently with its integrated processing of Pix4DMapper and edits DOM with EPT.The practice results show that the Pix4Dmapper can efficiently complete the production of UAV aerial photography products without manual intervention,post results using EPT processing,could meet the requirements of high precision DOM in dense forest areas in related specification.The method implements the combination between the softwares,reduces the difficulty of operation,and improves the work efficiency.
