建筑三维重建方法综述

A review of 3D reconstruction methods applied in buildings

三维重建作为一种逆向工程技术,其目的是将现实世界中目标的三维几何信息以数字模型的形式储存在计算机中。三维重建在城市规划、智能建筑、施工管理等场景中发挥着重要作用,也是建筑领域的一个研究热点。本文首先从硬件层面介绍了三维点云数据的获取,然后介绍了三维点云数据面向具体任务的应用及对应的算法,最后结合科研领域与实际应用的现状,对三维重建的未来研究重点和发展趋势做了展望。

As a reverse engineering technique, 3D reconstruction aims to store the 3D geometric information of an object in the real world in the form of 3D digital models in the computer. 3D reconstruction plays an important role in urban planning, intelligent building system, construction management, and other scenes. 3D reconstruction is key research in the field of architecture and civil engineering. The study first introduces the acquisition of 3D point cloud data from the aspect of the hardware. Then, some applications of 3D point cloud data and the corresponding algorithms are introduced. Finally, by concluding the current researches and practical applications on 3D reconstruction, the future study and developing tendency of 3D reconstruction are discussed.
