摘　　要：本文简要介绍了三维物体深度数据的获取方法,重点叙述了采用有源三角形法获取深度数据的系统构成和原理。在简要介绍对深度图象的表述方法之后,叙述了用Delaunay三角形化实现的深度图象表面的表述方法,并给出了用这种方法对三维物体深度图象进行表述的实验结果。从实际结果看出,这种表述方法具有简单、压缩比高的特点。The paper introduces briefly the methods or acquiring the range images of threedimensional (3D) objects, and then puts emphasis on a system configuration and the fun-damentals of acquiring range images by the method of active triangulation. After a brief in-troduction to the representation methods for range images, a representation method for thesurface based on Delaunay triangulation is presented. Experiments on the actual range im-ages of 3D object show that the method is characterized by its simpler program structureand higher compression ratio.
