投射点

As to the remaining parameters, two methods are developed: first, accepting that the projection function complies with a circular function within at least a part of a given field of view, constrained by the obtained object-to-image radial mapping and a constant focal length, the best-fitting point of the optical origin is tested along the optical axis; secondly, referring to the postulation of the exclusively bilateral mapping between an imaged point and its scenic sight ray, a measuring technique is developed to survey the world coordinates which will fabricate a projecting path to the imaged points located on the imageable region of the image plane in order to directly model the projection geometries involved.

而针对其余参数本文提出两种解题方法：其一是根据『在「部分视野角范围」内，鱼眼相机的投射模型符合一典型的「圆形函数」』以标靶实体与其影像尺寸为限制条件，测试光学轴上的最佳视觉参考点、鉴定最适当的投射模型、焦距、及有效的视野角度范围。其二是根据『一视野线排他性地与对应「呈影点」一一映射』参考一呈影点来搜寻空间中对应视野线的绝对座标后，据以演绎相机内部影像形成的模型。

The second algorithm compute 2k P directly from P, where P is a random point on an elliptic curve, without computing the intermediate points, which is faster than k repeated doublings.

该算法从P直接计算2~kP，不需要计算中介点，因此较k次倍乘快，其实现效率与投射坐标下的算法相当。

A planetarium instrument is housed in the center of a room with a hemispherically domed ceiling; the instrument projects points of light to the ceiling to simulate the night sky from various perspectives (seasonal, or historical views of the Earth-sky relationship).

大型穹顶天文天象仪被封装在一幢房子里，落成在其中一个房间的中心，房顶是半球型活动的天花板，通过将光点投射在屋顶天花板上，来模拟夜空中天象的季节变换和历史上著名的地球天象情景。

To realize the real-time tracking of the shoot point from light pen,the Camshift tracking algorithm is chosen,but it is difficult to track the point with dynamic and complicated background and in case that there is similar color with the shoot point.

为实现对光笔投射点的实时跟踪，采用了Camshift跟踪算法，但是该算法在动态复杂背景及在颜色相似的背景区域中不能很好地进行跟踪。

Secondly, we investigate C°-flows on orientable closed surfaces having POTP, and obtain a necessary and sufficient condition of such flows.

剖析了这些轨道的邻域的轨线结构，还考虑了经过Poisson稳定点及几乎周期点的横截圈和相应的回归映射，其中本文讨论了可定向闭曲面上具有伪轨跟踪性质的C〓-流，得到了可定向闭曲面上C〓-流具有伪轨跟踪性质的较为简洁的充分必要条件；最后本文借助于从可定向的闭曲面到不可定向闭曲面的复叠投射，讨论了不可定向闭曲面上的C〓-流与其提升的轨线之间的联系，解决了不可定向闭曲面上C〓-流具有伪轨跟踪性质的判定问题。

In the world, most of the work is using the ray casting method for such a hybrid rendering. This is because the sample point of geometric objects can be conveniently inserted into the sequence of points in the volume along a ray line.

国际上关于这方面的工作很多，但基本上是运用光线投射方法进行混合成象，因为在每条成象光线的数据样点序列中，便于插入几何形体的样点。

Nevertheless, one might indicate a series of major steps as follows: the discovery of the early forms of the Oedipus complex and those of the ego and the superego, and the importance of the splitting, projective, and introjective mechanisms for building up the child's internal world; the discovery of the crucial place in development of the depressive position, linked with the infant's awareness of his mother as a whole and separate person; the discovery of the anxieties and mechanisms operating before the depressive position in the paranoid-schizoid position, the point of fixation of the schizophrenic group of illnesses; and finally the discovery of early oral envy and its influence on the early stages of development.
