The method relies on the facts that the row vectors composed of all the image points span, the same linear subspace as the row vectors composed of 3D space points span and that a basis of the subspace can consist of two row vectors composed of all the image points and one row vector in 3D space that is orthogonal to the former. The row vector can be determined, and the 3D reconstruction is accomplished. The novelty lies in the fact that the method can treat all the image points uniformly.

利用所有图像序列构成的行向量生成的子空间之和与三维空间点构成的行向量生成的子空间是同一线性子空间、同时由所有图像点构成的2个行向量外加一个行向量就可以组成该子空间的一个基底的特性,线性地求取子空间中的行向量,最后完成三维重建。

Let's have a look at of the following works of Shang Yang: Huangtu Gaoyuan Mother (1983), A Vehicle (1986) and A Family (1987). One striking feature of these paintings is the deletion of the perspective three- dimensional space composition. There is no close shot, no medium shot and no long shot in these paintings; there's no foreground or background either. The relation between human beings and environment in these works are by no means perspective.

让我们看看《黄土高原母亲》(1983)、《车儿》(1986)、《一家子》(1987)等作品,这些作品的一个显著特征是取消透视的三维空间构图,它们没有通常意义上的近景、中景与远景,也没有通常意义上的前景与背景,画面上的人与环境的关系是非透视的。
