透视的

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。

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。"

The value is in its composition, with its three-dimensionality, mid-point perspectives and vaguely religious symbolism (the donkey recalls the entry into Jerusalem) recalling the influence of Renaissance masters such as Fra Angelico and Masaccio.

参见Economist的图片）其实它的价值在于各种元素的组合，以及它的三维表现方式，中点透视和隐含的宗教象征主义（那头驴让人联想起耶稣骑驴进入耶路撒冷），可以看出其受到了文艺复兴时期的大师例如福拉。安吉利柯和马萨乔的影响。

On the basis of the properties of central projection and orthographic projection, the differences of different rectification approaches based on orthographic projection are explained, and it is suggested that oblique-plane-rectified photograph can produce orthographic representation of flat terrain cover; differential rectification of RS imagery based on DEM can produce orthographic representation of waved terrain cover; and true orthographic rectification based on digital ground-object model can produce orthographic representation of single objects on ground.

根据中心投影和正射投影的特点，从理论上说明了不同正射投影纠正方法之间存在的差异，认为：基于透视变换的像片倾斜纠正可生成水平地表覆被的正射投影表达；基于DEM的正射影像微分纠正可生成起伏地表覆被的正射投影表达；基于数字地物模型的真正射纠正可生成独立地物的正射投影表达。

His transposing of traditional ink painting techniques and composition onto canvas meant the retention of large areas of white, unpainted ground, and a fluid use of the line, without recourse to the classical perspective and chiaroscuro of traditional western academic painting.

他将传统的水墨画作法和创作转换到油画画布上，表现为保留了大片的留白、没有画出的质地和线条的流畅运用，而不借助于西方学院派的经典性透视法和明暗法的绘画技巧。

The heritage that impressionism gave to modern man is more than just vivid colors; what is more important is that it opened a door for the expression of individual and diverse art. After that, cubism shattered classicalism's mirror of the single perspective.

印象派绘画带给现代人的遗产不仅仅是光鲜的画面颜色而已，更重要的是它开启了一扇通往表达个人的多元化的艺术之门，在此之后立体主义砸破古典主义单点透视这唯一的一面镜子。

Based on projective geometry,the research works about 3D invariances extraction and application have been done in this thesis as following:(1) The basic theories and concepts in projective geometry are systematically summarized. It includes:the camera models of perspective imaging,projective collineation,cross ratio,a simple compare about invariance among some geometry transformations,fundamental matrix,epipolar and epipolar line in epipolar geometry,and so on.

This is an untouched measuring way. The cameras are calibrated in the way of RAC two steps, first. With the polynomial interpolation, the pictures catched from the steel plate are treated to detect the edge in subpixel with a cross window arithmetic operators, which can fit non uniform illumination, keep the edge character and do filter in a better way. Three-dimensional scenery could be rebuilt from the two-dimensional pictures with the methods of least square fitting and contradictorily clairvoyance. Thus, the distance and its variance of two points in the given position of the plate can be achieved. It is expected that this study can provide a new and useful tool to the research on the theory of distortion of line heating.

这种非接触的测量方式，采用RAC两步法对摄像机进行标定，然后对采集到的钢板图像进行分析处理，通过多项式插值的方法，采用具有保持边缘特征和滤波功能，且能适应非均匀照明的十字窗图像边缘检测算子进行象素级边缘检测，再用最小二乘拟合法和逆透视法对二维图像进行三维重建，便可测出钢板上给定点的距离及其变化值，以期为水火弯板的变形机理研究提供一种新的检测手段。
