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。
3D real-world modeling (also called 3D reconstruction based on multi-view photos) is a rapidly developing new technology in recent years and has become a hot spot in computer vision and tilt photogrammetry. It is widely used in cultural relics protection, virtual tourism, emergency support, digital city and other industries. The technology uses a large number of mathematical algorithms, relying on photos alone can get the real target objects and urban construction scene of the three-dimensional model, at the same time, get the realistic texture of the target object. This kind of multi-view photos of target objects and the automatic reconstruction of three-dimensional model technology with minimal cost (ordinary digital cameras and smart phones) can step out of the professional field, and have entered into the field of mass consumption. The application prospect is extremely broad. The technology provides a new and perfect means of realization for the design of interior furnishings. This article briefly introduces the working principle of this technology, elaborates the limitations of traditional manual modeling and 3D laser scanning, and introduces the new technology and software into the design of interior furnishings through the example of indoor furnishings.
