To describe the anisotropy of microdamage of the crust block, we use the damage tensor that is expressed in the fissure density.

为描述地壳块体微损伤的各向异性，引入裂纹密度表示的损伤形式。

The trifocal tensor is the mathematical expression of trifocal geometry, it has strict constraints to correspondence points and lines in three images.
