透视投影

According to a theory of computer vision, the most general transformation that can occur between a scene plane and an image plane under perspective imaging is a plane projective transformation.

根据计算机视觉的理论，在透视变换的情况下，一个景物平面与一个图像平面之间的变换是平面投影变换。

This process is as follows: applying projective transformation on the plane, using interpolation method to acquired texture, and then mapping it on the model.

讨论了如何纠正平面纹理的透视变形，及其相应的纹理映射，其过程是在两视图重建的基础上，对原平面进行投影变换，并用插值方法获得纹理，从而映射到模型上。

On the small panel, Uccello arranged two portraits. The character and the horse have are in exact proportion, the front legs and the back legs of the horse are suitably foreshortened, even the shadow is extremely accurate, causing them to appear stiff and unnatural.

在小小的嵌板上，乌切洛游刃有余地安排了两组人像，人物和马匹比例准确，马匹的前后腿之间透视关系合理，连投影都经过了精心的计算，但也和乌切洛所有的作品一样，看上去僵硬有如玩偶。

In this paper, an approach to two problems in organic chemical teaching was made:(1) Determination of the type and the number of Cis-trans isomers of acyclic alkenes;(2)An easy way to convert a Fischer Projection into a zigzag representation.

对如下两个有机化学教学问题进行了探讨：(1)如何确定链状多烯顺反异构体的数目和类型；(2)单糖的Fischer投影式转变为透视式的简便方法。

Methods: Made a cylinder lens and a direct back projection tomography machine .

自制柱透镜及反投影机与电视透视机相结合，进行反投影试验。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
