Contour Clustering Analysis for Building Reconstruction from Lidar Data
نویسندگان
چکیده
Automatic building reconstruction from LIDAR data has become a hot topic for several years. Many methods and algorithms have been put forward to reconstruct the building models, such as of flat roof, gable roof, or other rectangular shapes. Among which, contour based method is an innovative one to simplify the focusing, detection and reconstruction of buildings. In this paper, the contour clustering is investigated deeply for the construction of complex buildings. At first, the contour based reconstruction method is reviewed. Then the contour cluster is defined with topology relationship and shape similarity. The experiments show the clustering technique can capture the structure of the building, providing a sound base for reconstructing buildings of multiple layers, curved surface and other complex shapes. * Corresponding author

Conditional Random Fields for Airborne Lidar Point Cloud Classification in Urban Area
Over the past decades, urban growth has been known as a worldwide phenomenon that includes widening process and expanding pattern. While the cities are changing rapidly, their quantitative analysis as well as decision making in urban planning can benefit from two-dimensional (2D) and three-dimensional (3D) digital models. The recent developments in imaging and non-imaging sensor technologies, s...
متن کاملBuilding Reconstruction from Lidar Data Using Iterative Regularization Approach
This paper presents a scheme for the reconstruction of building models from LIDAR data by using an iterative regularization approach. The proposed scheme comprises three major parts: (1) elevation slicing, (2) boundary regularization, and (3) roof determination. The idea of elevation slicing is similar to the elevation contour map, where each contour line indicates a height level. We select a h...
متن کاملBuilding Detection and Structure Line Extraction from Airborne Lidar Data
The development of LIDAR (Light Detection and Ranging) system makes the acquisition of 3D surface information more convenient and immediate than other geomatics technologies. However, the 3D coordinates of the surface features, such as the corners, edges and planes of buildings, cannot be obtained directly from the LIDAR data because of its blind characteristics. How to detect the feature locat...
