作者解决了从两个视图在投影框架中重建 3D 空间以及从两个给定视图人工生成场景的新颖视图的问题。结果表明，通过来自场景中四个非共面点和相应极点的对应关系，可以定义和重建射影不变量（称为射影深度），稍后可以使用它来重建场景的射影或仿射结构，或直接生成场景的新颖视图。这种推导的优点是在计算过程中不需要恢复观看变换矩阵。<<ETX>>
The author addresses the problems of reconstructing 3-D space in a projective framework from two views and of artificially generating novel views of the scene from two given views. It is shown that with the correspondences coming from four non-coplanar points in the scene and the corresponding epipoles, it is possible to define and reconstruct a projective invariant, referred to as projective depth, that can be used later to reconstruct the projective or affine structure of the scene or directly to generate novel views of the scene. The derivation has the advantage that the viewing transformation matrix need not be recovered in the course of computations.<<ETX>>
