空间中一般位置的六个点的集合有三个射影不变量。众所周知，这些不变量不能从一幅图像中恢复出来，然而空间不变量和图像不变量之间确实存在着不变量关系。该不变关系将首先针对单个图像导出。然后，当多幅图像可用时，该不变量关系被用来导出空间不变量。
There are three projective invariants of a set of six points in general position in space. It is well known that these invariants cannot be recovered from one image, however an invariant relationship does exist between space invariants and image invariants. This invariant relationship will first be derived for a single image. Then this invariant relationship is used to derive the space invariants, when multiple images are available.
