面向真正射影像处理的对象定义及其语义关联

The Definition of Objects and Semantic Relationship for Object-oriented True Ortho Image Production

真正射影像作为新一代数字影像产品,其应用需求日益广泛。随着高分辨率倾斜影像的日益可得,逐像素处理的真正射影像生产方法局限性越来越突出。为此,针对面向对象的真正射影像处理,本文提出了物方对象和像方对象的概念,并描述了两类对象间的语义关联关系,并用实例分析了其特殊价值。

True ortho-photo has played increasing important role in urban applications, instead of traditional ortho- photo. There are a lot of problems during true ortho-photo generation process under the pixel-oriented strategy, especially for the high resolution images. It is necessary to promote a high-level object-oriented strategy instead of a low-level pixel-oriented strategy. This paper defines physical objects and image object containing geometric and semantic information and also establishes the relationship between the physical objects and image objects. At last, the special application value of the objects and semantic relationship has been analyzed.
