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... 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。 展开更多

This paper deals with two case studies: (a) The role played by geometry and physical objects in Galileo's Theoremata Circa Centrum Gravitatis Solidorum comparing with Archimedean approach-mental experiments, and method of composition and de-composition, circumscribed and inscribed figures on centre of gravity studies; (b) The complex network of relations, which in Mysterium Cosmographicum, links the experimental part of astronomy to the theoretical aspect and, in the case of Kepler, the metaphysical aspect. The authors focus their efforts on understanding why Kepler reached such a strange, genial and original connection between practice and theory. The aim of this paper is to discuss the relationship between physics-mathematics (-metaphysics) and between experiments-observations-theory in the work of two scientists, Galileo and Kepler. 展开更多
