3D modeling of reality (also known as 3D reconstruction based on multi-view photographs) is a new technology of rapid development in recent years, become a hot spot in the ifeld of computer vision and oblique photogrammetry , and in the protection of cultural relics, virtual tours, emergency safeguard, digital city, and other industries widely used. The technology uses a large number of mathematical algorithm, relying only on photos can get real objects and the 3D model of urban construction scene, at the same time obtain realistic texture of the target object.The minimum price to (ordinary digital camera and smart phone can) get more multi-view photographs of target objects and automatic reconstruction of 3D model technology has been out of the professional ifeld and into the ifeld of mass consumption, then, application prospect is extremely broad. The technology provides a new perfect means of implementation for the effect of the traditional interior furnishings design. This paper brielfy introduces the working principle of this technology, illustrate the traditional manual modeling and the limitations of 3D laser scanning, As example, turn decorations simple photographs into 3D model, introduce this new technology and automatic 3D photogrammetry software in the interior furnishings design ifeld.%三维实景建模（也称基于多视照片的三维重建）是近几年快速发展的新技术，成为计算机视觉和倾斜摄影测量领域中的研究热点。它在文物保护，虚拟旅游，应急保障，数字城市等行业得到广泛应用。该技术采用大量数学算法，仅依靠照片就能得到真实目标物体和城市建筑场景的三维模型，同时，可获得目标物体的逼真纹理。这种以极小代价（普通数码相机和智能手机即可）获取目标物体的多视照片并自动重建三维模型技术走出了专业领域，已进入大众消费领域，应用前景极其广阔。该技术为室内陈设设计效果的呈现提供了一个崭新完美的实现手段。本文简要介绍这一技术的工作原理、阐述传统手工建模和三维激光扫描的局限，以室内陈设摆件品为例把这新技术和软件引入室内陈设设计当中。
