集中阐述了基于CAD的物体模型建立过程，并介绍了一种基于规则的将物体几何模型予编译为匹配树的三维物体定位方法。
In this paper, we first focus on the CAD-based object model construction and then introduce a rule-based method to precompile this geometrical model into a match tree for 3-d object orientation.
这个实验，我们用一种用平行轴固定的两台同步摄像机定位系统来跟踪一个三维空间中的移动物体。
In this experiment we use a stationery system with two identical cameras with parallel axes to track a moving object in three dimensional space.
