传统正射影像由于存在投影差而产生遮蔽问题,为了解决这一问题,真正射影像应运而生。通常制作真正射影像的方法,需要花费大量复杂的算法去检测遮蔽区域以及补偿纹理。文章提出了一种思路,使真正射影像的制作方法更简易。即利用无人机倾斜摄影以及ContextCapture软件,通过空中三角测量计算、三维重建等步骤生成三维场景模型,继而由模型计算出TDOM成果。整个过程操作简易、工作量少、高度自动化,只需要少数人工干预便可得到成果,是传统复杂算法之外制作TDOM的一种尝试。

The traditional Digital Orthophoto Map (DOM) has the problem of occlusion due to the existence of projection difference. In order to solve this problem, the True Digital Orthophoto Map (TDOM) emerges as the times require. Usually, the method of making TDOM needs a lot of complex algorithms to detect the masking area and compensate the texture. In this paper, an idea is put forward to make the method of making TDOM easier. That is to say, the oblique photography by unmanned aerial vehicle and ContextCapture software are used to generate 3D scene model through aerotriangulation, reconstruction and other steps, and then the TDOM results are calculated from the model. The whole process is easy to operate, less workload, highly automated, and can be achieved with only a few manual interventions. It is an attempt to get TDOM in addition to the traditional complex algorithm.
