it was a routine way for graph- drawing based on coordinate data in application software to program and graph processing,because from coordinate data to graph it is uniqueness.in hydrologic analysis,we calculated related data according to figure parameters,as using rainstorm isoline to reckon average rainfall in the river basin.through examples and analysis,the paper proposed methods for curve numerical translation and area calculation by vb.

在应用程序编制和图形处理的软件系统中由坐标数据可以绘出图形是常规的途径，但有曲线图形，要生成坐标数据，至今还没有通用的方法，因为由坐标生成图形是唯一的，而反过来由图形转换为数据是非唯一的。在水文分析计算时，有时需要根据图形参数进行有关数据的计算，如用暴雨等值线图计算流域平均雨给出量的时候。通过分析和计算实例提出了利用vb实现可满足使用要求的曲线数值转换和封闭图形的面积计算方法。

对于无地理坐标的高分辨率遥感影像数据的镶嵌，由于缺少两幅影像的位置关系，以及影像几何变形的存在，镶嵌首先需要解决的就是获得两幅影像的位置关系以及消除影像的形变。

In the Cartesian coordinate system,compute the image plane revolution vector quantity caused by scan mirror′s rotation applying coordinate conversion and geometrical optics.

在笛卡尔坐标系中，通过数学坐标变换和几何光学的方法对不同工作方式的航空相机由扫描反射镜沿俯角方向旋转引起目标像旋转问题作定量计算，为偏流补偿机构工程应用提供理论依据。

This is because projected coordinate systems have a Y-axis which is the opposite of pixel coordinate systems.

这是因为预计坐标系统有一个Y轴是相反的像素坐标系。

Firstly, the object's position and orientation are determined by a vision system, the orientation of an object is the angle between the X-axis of the coordinate system and the axis of the least moment of inertia of the object in this system, and the position value is the vector between the coordinate zero point and the object's centre of gravity.

第一步利用视觉转动惯量法对任意放置在CMM工作台上的工件状态进行定位和定向；第二步利用测量离散点和模型投影点之间的关系，求取工件坐标系和设计坐标系之间准确的转换关系。
