However to produce high accuracy DEM, the technique of digital photogrammetrics and stereoscopic model are needed to editor DEM.

但要生产高精度DEM，一般是采用数字摄影测量方法，借助于立体模型对DEM进行可视化编辑、修改。

The transition of the theatrical mask art from a plane form to the present stereoscopic model represents the instantaneous flashes of the so-called time-space art.

这个从平面到立体的过程，形成了时空艺术的瞬间闪现，天真烂漫而不悖理性精神的美学，使画家的思想自由驰翔，令其笔下生辉。

The parameters describing the stereoscopic model are divided into two types: the main parameters and the adjustive parameters, and these two parameters are calibrated respectively.

把立体视觉模型参数划分为主值参数和调节参数，两类参数分别进行标定。
