我们完全确定了在范畴Γ~￡中的单对象和不可分解投射对象。

Similar to the case of order 3, the Jacobason radical of Γ_n, the simple objects and indecomposable projective objects of Γ_n~L are determined,we also give a estimate of the global dimension of Γ_n.

By using projective geometry and camera intrinsic parameters and calculating the distance between ship and landmarks, a method of locating ship by measuring the distance based on monocular camera machine vision is presented in this paper.

利用透视投影几何关系和摄像机内部参数，计算船舶与各陆标之间的距离，提出一种基于单目机器视觉的船舶测距定位方法。

As a matter of fact, more and more marketing activities become projective, and its management and business are operated through a great amount of projects, relative or irrelative.

Chain complexes of projective space and Klein bottle are well known.

射影空间和克莱因瓶链复合物是众所周知的。

Only four surfaces are possible for such embedding:the sphere,the torus,the Klein bottle and the projective plane.

It is natural to ask whether arrangements of linear varieties of different dimension in the projective space may be given with a similar axioms setting.

经典拟阵研究的是超平面在射影空间放置的公理体系。

According to the fact that the sum of linear subspaces, each of which is spanned by the rows of all points in each image, is equal to the linear subspace spanned by the rows of space points, projective depths are estimated.
