点

This is my last OpenGL for a project to use the "three-dimensional vector space / point" and related functions, they can use a definition of space vector / points, for the vector translation, zooming and rotation, the use of correlation function can also achieve two vector by the fork, get a Vectors absolute length of a vector unit, received a 3:00 decision vector perpendicular to the plane, a space to be the distance between two points, two vector to be the plot points, to be the angle between two vectors, such as operating for the use of user-friendly, each function is detailed Notes, it is particularly important if the calculation vector plot points, fork also took note, we hope to have useful.

这是我过去进行一个OpenGL项目时使用到的"三维空间向量/点"类及相关函数，使用它们可以定义一个空间向量/点，实现向量的平移，缩放和旋转等，使用相关函数还可以实现两向量的叉乘，得到一个向量的绝对长度，将一个向量单位化，得到一个三点决定的平面的垂直向量，得到空间中两点的距离，得到两向量的点积，得到两向量的夹角等操作，为方便用户的使用，每个函数都有详细的注释，特别重要的向量计算如点积，叉乘还有相关说明，希望对大家有所用处。

On the basis of distributive shapes of point collection on the Poincare section, define three indexes to quantitatively describe the distribution of point collection. Which are distance between two adjacent points, diffused angle and distance between every point and center point of point collection.

以庞卡莱截面上RR间期序列的点集分布形式为基础，提出点集中相邻点间距离、扩散角度和点到点集中心距离三项指标，用以定量地衡量点集的分布形式。

In this master thesis, we mainly discuss the adjacent vertex- distinguishing total chromatic numbers of some special graphs and prove that Zhang"s conjecture holds for these graphs. Then we get the adjacent vertex-distinguishing total chromatic numbers of the Halin Graphs. Moreover, we investigate the Generalized Petersen Graphs, prove that some classes of positive integers can"t structure the Generalized Petersen Graphs and get the result that the adjacent vertex-distinguishing total chromatic number is 5. Finally, based on the number and the parity of circles contained by the graph, we get the adjacent vertex-distinguishing total chromatic number of two classes of graphs.

本学位论文首先主要针对几个特殊图类讨论其邻点可区别全色数，验证了其满足图的邻点可区别全色数的猜想；再证明了非轮的Halin图的邻点可区别全色数；接着研究的是广义Petersen图，讨论了不能构成广义Petersen图的几类正整数，并证明了该图的邻点可区别全色数等于5；最后，根据图所含圈的个数及其奇偶性得到了两类图的邻点可区别全色数。

It is concluded that the precision of these points is attenuated equidistantly as concentric circles. Its center is the weighted average of the coordinates of known points with the radius determined by the precision, the quantity and the distribution of known points. The precision of station points is almost independent of intersection angle, and the precision of known points is almost independent of station point. In some circumstance, the detail points may be more precise.

对测站精度、细部点精度分布规律进行了分析，结果表明：测站精度和细部点精度均呈同心圆向外衰减，圆中心在已知点的加权平均中心上，半径决定于已知点的精度、数量与分布；测站精度与测站的交会角几乎没有关系，细部点精度与测站的位置几乎无关，且可能高于测站精度。

Thu February 22 nd The squad returns to England straight away, arriving at Gatwick at 2.10am and at Cobham just before 3am. The players will get to their beds between 3.30 and 4am. By the time they return to Cobham to train at 1.30pm, Terry has had his scan and no ligament damage at all has been shown. Unbelievably, he thinks he has a 50/50 chance of being fit for Sunday's Carling Cup Final.

球队直接飞回英格兰，凌晨2点10分到达Gatwick，凌晨3点之前抵达了科巴姆基地，3点半到4点之前，球员陆续回去休息，下午1点30分他们重新回到训练基地，特里接受了检查，结果显示他的韧带没有受伤，太难以置信了，他还不能确定是否能参加周日的冠军杯决赛。

Furthermore,we present the method for designing quadratic Bezier developable surface:give four corner points of developable surface and two free designing parameters,the other two control vertexes are on the line connecting the linear interpolation point between the first two control vertexes and the linear interpolation point between the last two control vertexes,and they are the linear interpolation points between these two linear interpolation points respectively,namely,these four linear interpolation points are colinear.

提出了二次Bézier可展曲面的设计方法：给定可展曲面的4个角点a0、b0、a2、b2和两个自由设计参数？姿、？滋，则待求的2个控制顶点a1、b1是在前2个控制顶点a0、b0的线性插值点a*与后2个控制顶点a2、b2的线性插值点b*的连线上，并且也是a*、b*这2个线性插值点的线性插值，即这4点a*、a1、b1、b*共线。

A calibration model was established by introducing a planar target that could move freely with three collinear and known mutual location points. The calibration point coordinates in a camera coordinate system could be calculated by using the imaging information of three points and the light stripes on image plane of the camera.

引入一个可自由移动的平面靶标，靶标上只需要共线且相互位置确定的3个特征点，利用共线三点建立三点透视数学模型，根据3个特征点以及光条纹在摄像机像面的成像信息，获取了光平面上标定点在摄像机坐标系下的坐标。

At a maximum of 9 Spores attached, the affected unit will be taking SERIOUS damage from enemy attacks. Even a non-upgraded Mutalisk will do 18 points of damage per attack with its bounce attack doing 12 and 10 points to any other nearby enemy units that also have 9 Spores attached. So as you can see, having air support for Devourers will not only help protect the Devourers, but they will also help take down the enemy at an incredibly quick rate.

一个附着了9点孢子的单位在被攻击时会承受严重的破坏力，即使是一个没有升级过攻防的飞龙也会对它产生18点的攻击力以及而对其周围附着了9点孢子的单位产生12点和10点的弹射攻击（ps：：就是说1点的孢子加1的额外伤害，也就变相等于减盔甲）所以我们可以很容易理解，如果吞噬者在其他对空单位的支援下不仅可以保护吞噬者而且还能迅速的消灭敌人的空军。

This paper analyses the different influence on the fundamental matrix by the different matched points in images and theweighted factor is introduced to express the distance between the matched point and the epipolar line which has the obvious geometry meaning.

分析了图像匹配点对基础矩阵的不同影响，引入具有明显几何意义的匹配点到对极线的距离作为匹配点的加权因子，将匹配点集合看作随机变量并将加权因子作为匹配点的概率分布。在此基础上对原始图像数据进行归一化处理，利用8点算法得到基础矩阵。

First it selects a 3×3 neighborhood.According to whether gray value of arbitrary pixel is its neighborhood's extremum,all pixels are divided into doubtful noises pixels and signal pixels.Then it constructs 8 templets of orientation gradient for each doubtful noise,makes the sure of the noises sets according to the magnitude of 8 values of orientation gradient.

该算法首先对含有噪声的图像取3×3邻域，判断某点是否为邻域极值将全部像素点分为可疑噪声与信号点集合；其次对每一个可疑噪声点在其3×3邻域内构造八个方向的梯度算子模板，通过比较8个方向梯度的大小，进一步确定其是否为噪声点；最后对噪声点进行邻域的中值滤波。
