This paper systemically elaborates map projection and map projective transformation.

1引言如何将地球空间信息通过一种数据交换表现在平面中，是地图投影研究的范畴。

This paper proposes a new concept of remote sensed image, which can be considered as the mapping mode of the spectral space for ground features to the projective space that is two-dimensional imaging space.

影像纹理是影像的一个重要属性，在影像分析中占据十分重要的位置，对于目标特征的提取和各类目标的识别都具有重要的价值。

Rosen projective gradient method is used to find the approximated KKT points of relaxed problem, and then the index set is updated until the minimal solution is .

本文采用Rosen 投影梯度法求此松弛问题的近似KKT点，然后更新指标集不断迭代直至得到最优解。

According to if there exists a one to one mapping between the two point sets to be matched, PPM can be divided into the case of complete matching and the case of incomplete matching. According to transformation type between the two point sets, PPM can be divided into the affine (including Euclidean and similarity) case and the projective case.

点模式匹配问题，根据待匹配的两个点模式是否存在一一对应的匹配关系，可分为完全匹配情形和不完全匹配情形；根据两个点模式之间满足的几何变换关系，可分为仿射变换（包括相似变换和欧氏变换）情形和射影变换情形。

A notable merit of parallel coordinates is its well-founded mathematical foundation.Its projective geometrical interpretation and duality properties facilitate the simultaneous projection information representation of multiple low dimension subspaces.

平行坐标的一个显著优点是其具有良好的数学基础，其射影几何解释和对偶特性使它可以很好地同时表达高维数据在多个低维子空间的投影信息。

In order to solve these problems, a direct interpolation algorithm for the projective curve on parametric surface is proposed in this paper.

针对这种情况，文中针对参数曲面上以投影方式形成的空间曲线轨迹，提出了一种直接插补算法。

The practical problem of the arbitrary plane angle (the edge of the angle is the line at arbitrary position) in space and its projective angle is analyzed and studied in this paper.

本文对空间任意平面角（角边可为任意位置的直线）及其投影角这一具有实用性的几何问题进行分析研究；用几种不同的解析方法得出在各种情况下的关系式，从而能以最少的参变量，进行准确而简便的计算。

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。

Also, the inversion is designed in the projective coordinates that will save much computation time.

另外我们采用Projective座标系统，将除法运算转变为乘法运算，进而降低运算结果的时间。

You can do some assertiveness training.

你可以进行一些自信训练。

We were well on the path to making a rear-wheel-drive global platform," says Mays."

我们正致力于建立一个后轮驱动的平台，"Mays这样说道。"
