摘　　要：在机器视觉的工程实践的很多场合中,以直线基元为基础的三维重建,不但会提高检测系统的效率、有利于实现在线检测,而且能够解决一些特定环境下三维重建的难题。为满足如此需求,对以直线为基元的三维重建进行分析与研究,按照立体视觉的物理意义,推导了直线三维重建的模型,并据此完成了实验系统搭建。实验研究表明,所构建的系统能够实现直线基元的三维重建,并具有较高的精度,可以满足工程实际应用的精度要求。For many occasions in engineering practice of machine vision, the three-dimensional （3D） reconstruction based online primitives not only improves the efficiency of detection systems and realizes online measurement, but also solves some problems of3D reconstruction in specific environments. To meet such needs, the 3D reconstruction is analyzed and researched based on linear prim-itives. In accordance with the physical meaning of the stereo vision, the 3D reconstruction model of a line was derived, and further anexperimental system was set up. The experiments show that the system built can realize the 3D reconstruction based on linear primitiveswith high precision, and can meet the precision requirements of engineering practice.
