提出了一种三维工业物体的多重描述与识别方法，在描述中采用了整体形状描述，基元属性描述和关系描述相结合的多重描述策略；在识别过程中#首先根据物体的整体描述产生关于物体身份的初步假设，然后提出三种修剪算法，充分利用关系数据结构的多重约束作为知识启发来修剪搜索树#最后根据距离测度函数实现精匹配。实验验证了上述处理的正确性和一般性。

In this paper,a kind of description and recognition method for 3D objects is presented. The multiple description approaches are firstly presented,including general description.unit attributes description and relational description. In the procedure of recognition.after creating the primary assumption about object idcntilication,authors present three prunning algorithms to prune the search tree. Then,the distance measure is used to realize the final recognition. Finally,some experiments are given out.
