Affine geometry is often assumed in model-based vision systems because fewer features are required to compute model pose uniquely under affine projection and the perspective projection.

根据三维实体的二维透视图像构造关于该实体的不变因子是一项困难的任务，也是当前将不变因子理论应用于计算机视觉的一个主要目标。

Topics include: line generators, affine transformations, line and polygon clipping, splines, interactive techniques, perspective projection, solid modeling, hidden surface algorithms, lighting models, shading, and animation.

章节中包含：线的生成，仿射转换，线和多边形的裁切，样条线，互动技术，透视投影，实体模型，隐藏面算法，明暗模型，阴影，和动画。

Then, the local affine motion model is given under the perspective projection model.

需要指出的是，该模型也可以用其它合理的运动模型来代替。

Whereas parallel projections are used to project points onto the image plane along parallel lines, the perspective projection projects points onto the image plane along lines that emanate from a single point, called the center of projection.

与平行投影沿着平行线将物体投影到图像平面上不同，透视投影按照从投影中心这一点发出的直线将物体投影到图像平面。

With the constraints of these feature points, perspective projection, coplanarity and colinearity, the curved surfaces can be recovered by minimizing the linearly constrained quadric objective function.

把特征点的位置、共面、共线、透视投影等作为约束，通过最小化线性约束下的二次目标函数实现曲面重建。

The accurate selecting of homonymous points has two situations: when labels exist in the scene, the label's central coordinate is obtained as the homonymous points; and when there are no labels in the scene, all points are firstly displayed in perspective projection's way in the OpenGL environment, and then the homonymous points are selected by man-machine interaction.

同名点的选取分为两种情况：当场景中有标签时，本文提取了标签的中心作为同名点；当地理场景中不存在标签时，本文将两站点云以透视投影的方式在OpenGL环境中显示出来，然后通过人机交互选择的方法获得同名点。

Based on perspective projection model,a modified parallel projection method for flying pose measurement is proposed.

摄影系统的成像满足透视投影模型，使用平行投影法做飞行姿态交会存在模型误差。

This approach utilizes the fact that if the centerline of target image gets through the center point of the image plane,perspective projection and parallel projection must have the same image-forming property.

依据在目标成像的中轴线通过像面中心的时候，平行投影法和透视投影法有相同的成像特征这一事实，提出了一种无模型误差的修正平行投影法。

Parallel projection transformation and perspective projection.

投影变换有平行投影和透视图。
