透视

In aerial perspective,objects closer to the viewer are painted in brighter colors and greater detail than those farther away.

在空气透视法中，在更明亮的色彩中，物体显得更靠近观察者，并且与远处的物体相比更大。

Affine geometry is often assumed in model-based vision systems because fewer features are required to compute model pose uniquely under affine projection and the perspective projection.

根据三维实体的二维透视图像构造关于该实体的不变因子是一项困难的任务，也是当前将不变因子理论应用于计算机视觉的一个主要目标。

Topics include: line generators, affine transformations, line and polygon clipping, splines, interactive techniques, perspective projection, solid modeling, hidden surface algorithms, lighting models, shading, and animation.

章节中包含：线的生成，仿射转换，线和多边形的裁切，样条线，互动技术，透视投影，实体模型，隐藏面算法，明暗模型，阴影，和动画。

This method represents the virtual objects in Euclidean space instead of in affine space, which is consistent with the popular graphics rendering tools such as OpenGL and is more common in practice. A new classification based local and global tracking strategy to match features between the reference image and the currently frame directly is presented, which enables the augmented reality system working effectively even under large changes of viewing angles. A novel affine coordinate system definition method based on a collection of feature points is also proposed, which makes the tracking method effective even when not all the reference points are detected during the whole process, as long as there are at least four pairs of reference points correspondences.

该方法以仿射变换为桥梁来建立欧氏空间下的摄像机坐标系与世界坐标系之间的变换关系，它与OpenGL等当前流行的图形渲染工具一致，具有更强的通用性；采用基于分类的自然特征匹配策略，能够在视角和视点发生大幅度变化情况下依然正常工作；提出基于特征点集合的仿射坐标系定义方法，使增强现实系统在最小配置下只需4点追踪成功即可完成注册，比需要6点的透视投影方法具有更好的健壮性和精确性。

On the poet's choice, mainly be decided by two standards, one is the popularity and influences of works; two is the meaning of the creations development that it create for the whole colony. Owing to above two standards, the writer chooses seven writers to launch the treatise, they are Jidi Maja, Jimu Langge, Luwu Laqi, Ma Deqing, Aku Wuwu , Asu Yuer, Eni-Mushashijia. In discussing the process, the writer used the nationality and Poetics of the poem as the latent clues, emphasized to inquiry into three main roads and three main realms. On the article structure, the full text mainly is divided into two parts, one is the concrete imago analysis to each poet creations, two is upon the analytical foundation the integration of the theories, with this the treatise could be united into an organic whole. In regard to the conclusion, we educe the characteristics of the colony is deep consciousness to the nation culture, also extensive exploration and attention to poetics. The blemish is the inside emotion and sensibility is similar or duplicate and that the creation pattern is narrow. The main develop threads of the colony are upon the female clan culture the diverse poem skill investigation, its nation culture value tropism present the rising spiral type of return- leave- return again.

在研究方法上，本文以意象分析法为贯穿全文的主要方法，通过对意象的具体分析来透视凉山诗群的诗歌世界；在诗人的选择上以其作品的影响力及意义为标准，选择了这一诗群的七位诗人展开论述，他们分别是吉狄马加、吉木狼格、倮伍拉且、马德清、阿库乌雾、阿苏越尔、俄尼·牧莎斯加；在论述过程上，笔者以诗歌的民族性和诗性作为前后贯穿的潜在线索，着重探讨了这一诗群创作的三个主要倾向和三个主要领域，前者详论，后者略述，具体表现在对前三位诗人的论述以诗人论的形式详细展开，探讨他们所代表的凉山诗群发展过程中的三个主要创作倾向，即民族文化的深层开掘、诗艺的实验性探索和艺术哲学的尝试性建构，对后四位诗人的论述则以主题的方式展开，探讨他们所代表的凉山诗群在爱情诗、乡土诗和文化诗三个领域的探索；在文章结构上，全文主要分为两大板块，一是对各位诗人创作的具体意象分析，二是在前文分析的基础上进行理论的整合，以此将前面散珠似的论述贯穿成一个有机整体；在结论上，我们通过整合得出：1、凉山诗人群新时期以来诗歌创作的大致发展脉络：在母族文化的基质之上的多元诗艺探索，其民族文化价值取向呈现为回归—离去—再回归的螺旋式上升形态；2、新时期彝族凉山诗人群汉语诗歌创作的特点，即民族文化意识的深层自觉，对诗性的关注和探索；3、新时期彝族凉山诗人群汉语诗歌创作的缺陷，即情感意蕴的雷同和创作格局的狭小。

The "so-called new Americanist criticism of the last two decades," we read, tends to see the tensions between margin and center (in particular of race, ethnicity, gender, class, and sexuality) as more central to U.S. cultural history than any supposed aesthetic mainstream.... No longer does it seem so self-evident that Emerson and Transcendentalism were the gateway to U.S.

我们看到："所谓过去二十年里美国问题的新批评倾向于透视边缘和主流（特别是在种族、人种、性别、阶级和性方面）的紧张状态，它比任何可以想像的美学主流都接近美国的文化史……爱默生和先验主义是美国文学涌现的通道的说法看起来不再那么顺理成章。"

A variety of other factors seem to be brought into play with varying degrees of influence, such as linear perspective , detail and aerial perspectives, interposition, and etc.

它不仅是用双眼进行三角测量的过程，还有其它许多因素不同程度地产生影响，比如线性透视、细节与空中透视、干涉等等。

Sunlight on a field of grass may appear even if it is a cloudy day. Linear and atmospheric perspective can be distorted if the result is a better look. Cast shadows can be longer than they would appear at a specific time of day.

即便是的阴沉的天气，阳光也可能在草地上出现；为了获得不错的画面效果，线性透视和大气透视关系也是可被扭曲的；在某些特定的时刻，可将影子描绘成比它的本来面目更长。
