Aimed at the needs of divagation in virtual environment, we define the position chain, time chain, zooming chain and virtulized chain. Also, a divagation strategy is proposed for vitural panorama space containing position relationship, time relationship, zooming relationship and virtualized relationship.

针对基于图像的虚拟全景空间漫游的需要，在定义位置链、时间链、焦距链和虚化链等链表结构的基础上，提出了一种包含位置关联、时间关联、焦距关联和虚化关联的大规模虚拟全景空间漫游策略。

The approach is based on the principle that the a pa rticle will form double points on the image plane when the particle is out of fo cus in an optical system with a two pinhole lens.

该方法是当利用双孔透镜成像时，单点粒子在离焦光学成像系统中会形成包含粒子空间信息的两点像，根据粒子像在像平面上的位置和间距可以获取空间粒子的三维空间位置。
