Secondly, in the determination of the homography of the plane at infinity, it relies neither on projective reconstruction nor on the homography of a space plane, it needs only some image correspondences and epipoles, which are basic requirements for any camera self-calibration technique.

该方法主要优点在于：在确定无穷远平面的单应性矩阵的过程中，不需要射影重构，也不需要有限远平面信息，唯一所需要的信息是图象极点，从而简化了文献中现有的算法。

We studied the properties of the projective cone in tensor vector space defined by Barker.

给出了张量空间中射影锥可分解的充分必要条件，并由此可得出有限维实空间中真正锥可分解的已有结论。

A useful concept,Foliage Projective Cover that means the percentage of the land covered by foliage,was introduced,it had some ecological significances and was suitable for describing horizontal character of plant community.

本文引入植物群落叶片投影盖度的概念，其含义是植物群落叶片覆盖地表的百分率，它具有生态意义明确、适于描述植物群落水平结构的特点。

By this equality,we prove that the amplitude of a compact DG module M over a cohomologically bounded DG algebra A is just the sum of the amplitude of A and the projective dimension of M.

对于一个同调有界的连通DG代数上的紧的DG模，我们由此等式可得其振幅与DO代数的振幅的差恰是它的投射维数。

We shall interrupt the history of projective geometry.

我们要把射影几何的历史断开。

Approaches based on projective geometry are often associated with reference points given as prior knowledge.

其中，基於透视投影几何的方法，常与参考点所提供的已知资讯有所关连。
