Semantic Labeling of 3D Point Clouds for Indoor Scenes
Inexpensive RGB-D cameras that give an RGB image together with depth data have become widely available. In this paper, we use this data to build 3D point clouds of full indoor scenes such as an office and address the task of semantic labeling of these 3D point clouds. We propose a graphical model that captures various features and contextual relations, including the local visual appearance and ...
متن کاملLuminance-Corrected 3D Point Clouds for Road and Street Environments
A novel approach to evaluating night-time road and street environment lighting conditions through 3D point clouds is presented. The combination of luminance imaging and 3D point cloud acquired with a terrestrial laser scanner was used for analyzing 3D luminance on the road surface. A calculation of the luminance (cd/m) was based on the RGB output values of a Nikon D800E digital still camera. Th...
متن کاملSurface Reconstruction from Unorganized 3D Point Clouds
Computer-based surfacemodels are indispensable in several fields of science and engineering. For example, the design and manufacturing of vehicles, such as cars and aircrafts, would not be possible without sophisticated CAD and simulation tools predicting the behavior of the product. On the other hand, designers often do not like working on virtual models, though sophisticated tools, like immer...
متن کاملUsing a linear octree to identify empty space in indoor point clouds for 3D pathfinding
Indoor pathfinding and routing need fast ways to define connected navigable space, which represents usable paths. This is important because the interior space in buildings changes and often does not follow the architectural design. A workflow is presented that uses a linear octree to segment the space contained in an indoor point cloud, and subsequently derives the structured and connected empt...
متن کاملGrammar-supported 3d Indoor Reconstruction from Point Clouds for “as-built” Bim
The paper presents a grammar-based approach for the robust automatic reconstruction of 3D interiors from raw point clouds. The core of the approach is a 3D indoor grammar which is an extension of our previously published grammar concept for the modeling of 2D floor plans. The grammar allows for the modeling of buildings whose horizontal, continuous floors are traversed by hallways providing acc...
