This paper has done some studies on arithmetic for this system: presents a method of detecting and tracing moving objects in real time, and analyses their height using the restriction of vanishing line s, vanishing points and cross-ratio in perspective geometry.

文中为实现这种智能视觉监控系统做了一些算法上的研究工作：实现了对运动物体进行实时检测和追踪，并利用透视几何中的消影点、消影线以及交比的约束方法对运动物体高度进行了分析。

Therefore based on image line observation, the adjustment model of correlation between line and vanishing point is constructed to determine the location of vanishing point from the viewpoint of photogrammetry.

分析了长焦距相机因视场角小在应用灭点标定时遇到的问题，首次研究了专门针对长焦距、小视场角相机的基于点线混合的标定方法。

Based on a summary of the methods for photographic survey of strike-dip of structural surfaces on rock slopes, the vanishing point deduction method and its calculation formula are proposed, and the method of vanishing line is further illustrated.

应用这两种方法，在野外产状测量时，须进行方位的控制，而不需要任何长度和高度的控制测量；在内业中也不需要计算任何空间点位置，从而可以减少控制测量工作，增加了摄影外业的灵活性。

Firstly, need some geometric information which include the vanishing line of the ground plane, a vanishing point for the vertical direction and a known vertical height.

该方法首先根据单幅图像提供的一些几何信息———地平面(或者是与地平面平行的平面)上两对不同方向的平行线和竖直方向的一对平行线———在图像上求得地平面的消影线和竖直方向的消影点；然后，用一个已知的参考高度来确定高度测量方程中的比例因子α；最后只要输入待测高度的端点坐标就可以获得该高度的实际值。

There are two components to the reconstruction process. First, the camera calibration and metric structure of each plane is computed, that is to calibrate a square pixel camera from three vanishing points of orthogonal directions and metric rectify each plane by computing the imaged circular points and the vanishing line.

首先 ，相机定标和计算每个平面的度量信息，即先基于 3组互相垂直方向的影灭点，对方形像素相机标定，再利用影灭线和圆环点像，对每个平面度量校正；然后考虑每个校正平面的尺度因子和非正交平面间的相对面向，从而将所有校正后的平面缝合起来。

The knowledge of vanishing point is an important step for oncoming camera self-calibration and 3D reconstruction. Under perspective projection, lines paralleling each other in space will converge to a point called the vanishing point in the image plane.

在人造建筑物的图像中，存在着许多空间上相互平行的直线，这些直线经过透视投影后将在成像平面上相交于一点，称为消隐点。

In Single Point Perspective,the designer can also determinate Vanishing Point anywhere on the horizon with the need of design's expression effect.Determining Vanishing Points on the horizon in two-Point Perspective,designer draws one of Measurings with the need of design's expression effect.The another can be draw by two circular arcs in the vertical.It solute the problem easy and convenience without drawing by experience of Perspective and confirmed by memory of the Perspective Rule.

在一点透视中，确定直线长度距点也可以是设计者根据设计表达效果的需求任意确定；两点透视中确定直线长度的量点，其中一个是设计者根据表达效果的需求任意确定，另一个可以在立面图上用两段圆弧求出，方便、简单，解决了靠透视经验画图，靠记住透视规律验证的草图、效果图的问题。

Yes, there is a rumour that a young pale beam of a crescent moon touched the edge of a vanishing autumn cloud, and there the smile was first born in the dream of a dewwashed morningthe smile that flickers on baby's lips when he sleeps.

是的，有谣传说一线新月的微笑，触到了消散的秋云的边缘，微笑就在被朝雾洗净的晨梦中，第一次生出来了--这就是那婴儿睡梦中唇上闪现的微笑。

Tara appears in Buddhism, Jainism, and particularly, Tibetan Lamaism, as a complex array of manifestations: goddess of ascetism and mysticism, mother creator, protectress of all humans as they cross the sea of life.

度母出现在佛教，耆那教里面，尤其是西藏的喇嘛教，作为一系列的陈列阵容；神秘的女神，创世之母，人类横过生命之海洋的女性保护者。
