摘　　要：BIM技术的发展推动了建筑业的一场新的革命,随着绿色建筑、智能建筑以及城市可持续发展概念的不断深化,现有的建模方式已经无法满足新时代模型的要求。三维实景建模技术在近年来广泛用于既有建筑的模型重建,如何实现高精度、快速率、低成本的实景模型是广大技术人员面临的重要问题,本文利用倾斜摄影技术实现三维实景建模并结合实际工程案例提出可实施性参考方案,并提出用实景建模的方法监测隧道洞口沉降量。The development of BIM technology has promoted a new revolution in the construction industry. With the deepening concepts of green buildings, intelligent buildings and urban sustainable development, the existing modeling methods can no longer meet the latest modeling requirements. In recent years, 3D real-time modeling technology has been widely used in model reconstruction of existing buildings. Thus, how to realize high-precision, fast-rate, low-cost real-life modeling becomes an important problem faced by numerous technicians. This paper uses the tilt photography technology to realize 3D real-world modeling. Based on an actual engineering case study, an implementable reference plan is proposed, and the real-world modeling method is used to monitor the settlement of the tunnel entrance.
