摘　　要：随着航空摄影测量的发展,数字正射影像(DOM)因具有较高的几何精度、完整的影像特征、较强的现势性等特点成为重要的基础地理信息产品之一,在国土资源调查、数字城市、土地确权、重大自然灾害应急保障等众多领域中占据着极其重要的地位。然而随着航测技术的进步以及航摄仪器的发展,传统正射影像因存在遮挡、重影、边缘模糊和套合不完整等问题越来越无法满足生产的需要,因此真正射影像受到从业人员的喜爱。该文基于倾斜摄影测量研究真正射影像生产过程中的关键技术,通过与普通正射影像的对比分析,阐述真正射影像的优势与特征。With the development of the aerial survey,digital orthophoto map(DOM)has become one of the important basic geographic information products due to its high geometric accuracy,complete image features,and strong presence.It is used in many fields such as land and resources surveys,digital cities,land right confirmation and major natural disaster emergency protection,which occupies an extremely important position.However,with the progress of aerial measurement technology and the development of aerial photography instruments,traditional digital orthophoto map is unable to meet the needs of production due to such problems as occlusion,double shadow,blurring edge and incomplete set.Therefore,real digital orthophoto map arises at the right moment and is favored by practitioners.Based on the research of the key techniques in the production of real projective images by oblique photogrammetry,this paper expounds the advantages and characteristics of real digital orthophoto map through the comparison and analysis with ordinary normal digital orthophoto map.
