基于无人机航摄的真正射影像制作方法探讨

随着无人机航空摄影的不断发展和成熟,利用无人机航摄制作高分辨率数字正射影像图在测绘生产中应用日益广泛。但在城市区域制作大比例尺正射影像图时存在建筑物倾斜、遮挡严重、不能和GIS矢量数据进行很好套合等问题,而数字真正射影像图能很好地解决这些问题。本文基于INPHO软件对城市无人机航摄影像进行真正射影像制作,总结出无人机航摄影像制作真正射影像的作业流程和需要注意的关键问题。

Discussion about the Method of Making TDOM Based on UAV

With the development and maturity of the UAV aerial photography, the use unmanned aerial photogrammetric production of high resolution DOM is more and more widely applied in surveying and mapping production.But in the urban area of making large scale DOM exists in building inclination, occluded seriously, and not GIS vector data is well nested problems, While TDOM can solve these problems very well.In this paper, INPHO software for the city of UAV aerial photographic imagery based on TDOM production summed up the UAV photographic aerial making TDOM processes and the key problems need to be paid attention to.
