摘　　要：三维重建过程中线框模型往往作为中间模型出现,由于线框模型的二义性以及过于简单的信息制约了它的应用,通常都要将其转换为表面模型或实体模型。该文主要围绕三维重建中线框模型的表面构建问题,分析其中所面临的难点。根据三维重建源对象的不同,对直接从线框模型提取特征构建表面模型、面向线框模型从单幅线图构建表面模型以及基于多面投影图构建表面模型三个方面,综述了当前对线框模型进行表面构建的方法。在此基础上指出研究中尚存在的问题并展望未来的发展趋势。Wire-frame model usually appears as intermediate model in 3D reconstruction.However,the ambiguity and oversimplified information existing in this kind of model significantly restrict its practical application.It tends to be transformed into surface model and solid model.This paper mainly focuses on surface construction of 3D reconstruction,and the key points during this process are discussed.According to the source object of 3D reconstruction,this paper summarizes surface construction for wire-flame from three aspects：wire-flame transforming directly into surface model,reconstructing 3D model from a single drawing or image by wire-frame,and reconstructing 3D model from multiple projection.And on this basis,it points out the problems to be solved and the development direction for future researches.
