射影平面 meaning in Chinese

plane of projection
projection plane
projective plane

Minimum cycle bases of outerplanar graphs on the projective plane
射影平面上外可平面图的最小圈基
At the beginning , the basic theory of plane measurement ? some basic elements in planar projective geometry , including 2d protective plane , homogeneous coordinates and homography are introduced . the pinhole camera model and the basic algorithm of image measurement are discussed
首先介绍了平面测量问题的理论基础? ?平面射影几何的一些基本元素：射影平面，齐次坐标，平面单应等，接着讨论了摄象机针孔模型以及基于图象的平面测量基本原理。
In two - view case , a method is presented for calculation 2d projective transformation and construction the virtual elements by combination of spatial points and lines . so more 3d invariants of object ' s spatial structures can be extracted from real elements and virtual eleme nts . ( 3 ) the geometric characteristics of 2d symmetric objects " in perspective images are lucubrated
( 2 )扩展了2d射影变换矩阵的求解方法，将单纯利用点集对应的计算模式扩展到利用直线集、点线组合等多种类型来建立两个射影平面的对应关系；总结了平面上基于点、直线元素可求解的多种3d不变量；提出了双视图下由点、直线元素的多种对应关系求解2d射影变换来构造“虚元素”的方法，结合“实元素”和“虚元素”可以提取更多的空间3d不变量。
