| 5. | The four situations in the three basic projection planes are the only certifications to produce the direction and location , those who think that in these four situations projection planes may surplus is wrong
摘要三基面体系中的4种情况是形成方向和位置唯一固定的依据，证明了那种认为此4种情况中基面存在超越和重复的观点是错误的。 |
| 6. | One of the two arbitrary planes is formed by the origin and the projected line , which is called the inverse perspective projection plane , the other is perpendicular to the inverse perspective projection plane , and go through the 3 - d line
将其中的一个平面规定为由投影中心和投影直线所确定的平面，称之为反透视投影平面，而另一个平面规定为与反透视投影平面垂直相交且通过空间直线的平面。 |
| 7. | Because partial picture was shot from different direction , their projection plane has angle inevitably . to maintain spacial constraint relationship of actual scene and keep visual consistency , each partial image which describes its projection plane must be projected to one surface
由于局部图像分别是在不同的方向上拍摄的，它们的投影平面存在一定的夹角，为了维持实际场景中的空间约束关系，保证实际场景中的视觉一致性，必须将拍照得到的反映各自投影平面的各局部图像映射到某一曲面上。 |
