基于DMC航空影像的数字真正射影像制作研究

Research on the production of true digital ortho map based on DMC aerial images

随着影像获取手段和方式的不断提高,传统的数字正射影像已经不能够满足不同领域对于高质量、高精度测绘产品的需求,因此,数字真正射影像的出现成为一种必然的发展趋势。主要论述基于DMC航空影像的数字真正射影像制作的相关理论、主要方法和软件平台;并以哈兰诺公司MiraSuite软件平台为例,说明数字真正射影像的制作流程和具体实现,分析其在批量数字正射影像的制作中存在的问题。

With the improvement of image access means and ways, the traditional true digital ortho map can not satisfy a variety of applications because of the increasing demand for products of high quality and high precision,etc. The emergence of true digital ortho map becomes the inevitable trend of development. Discussion is made on the related theory, main methods and software platforms of TDOM based on the DMC aerial images. Taking the MiraSuite software platform （Harbin pock digital co., Ltd） as an example, it shows the TDOM production process and the specific implementation, and analyzes the present problems in batch TDOM production.
