一种新的生成ADS正射影像方法

DOM为不动产统一登记提供基础底图，但在制作ADS正射影像过程中，关键环节是如何快速有效地编辑出高精度的DEM，DEM的质量直接决定了正射影像效果。传统的处理方法是在立体下通过人工编辑特征点、线、面，优点是精度高，缺点是编辑效率低、周期长，投入人力物力大。本文基于此问题，提出了在华浩超算平台上利用地理国情基础数据辅助快速编辑DSM，从而生成高精度的ADS正射影像的方法。通过试验表明，该方法能够快速编辑DSM，从而生成符合精度要求的正射影像，在很大程度上提高了工作效率，具有广泛的推广价值。

A New Mothod to Generate ADS Orthophoto Image

ADS orthophoto image is mainly for the real estate registration to provide the basic base map,but in the production of ADS orthophoto imaging process,the key link is how to quickly and effectively edit the high-precision DEM,DEM directly determines the quality of the orthographic image.The traditional method of processing in the three-dimensional is to edit the feature points,lines,faces manually,the advantages is high precision, but the disadvantage is low, long cycle, put human and material resources. Based on this problem,this paper proposes a method to generate high-precision ADS orthophoto image by using the basic data of geography and national conditions to assist in the rapid editing of DSM.Experiments show that the method can quickly edit the DSM,so as to produce orthophoto images that meet the precision requirements,which greatly improves the work efficiency and has a wide range of promotional value.
