EXTRACTION OF BUILDING ROOF EDGES FROM LIDAR DATA TO OPTIMIZE THE DIGITAL SURFACE MODEL FOR TRUE ORTHOPHOTO GENERATION
LiDAR Aerial photos Edge Detection DSM True Orthophoto
2018/6/5
Various kinds of urban applications require true orthophotos. True orthophoto generation requires a DSM (Digital Surface Model) to project the photo orthogonally and minimize geometric distortion due ...
AUTOMATIC RECONSTRUCED ROOF SHAPES FOR LIDAR STRIP ADJUSTMENT AND QUALITY CONTROL
LIDAR Reconstruction Adjustment Building Point Cloud Quality
2016/2/29
In the recent years, the performance of LiDAR systems was improved by acquisition of the terrain surface with steadily increasing
point densities. However, the main error sources affecting the quali...
Building Roof Segmentation and Modeling from LIDAR Point Clouds Using Machine Learning Techniques
LiDAR Building Reconstruction Segmentation Feature Extraction Clustering Data mining
2015/12/4
This paper presents an approach to creating a polyhedral model of building roof from LiDAR point clouds using clustering techniques. A building point cloud is first separated into planar and breakline...
Generation of Roof Topologies Using Plane Fitting with RANSAC
LIDAR RANSAC building reconstruction roof topology city models rule-based approach
2015/12/4
For the acquisition of Digital Surface Models (DSM), LIDAR has proven a reliable and accurate observation technique. In contrast to the generation of a Digital Terrain Model, which can be derived from...
AUTOMATED DELINEATION OF ROOF PLANES FROM LIDAR DATA
Building reconstruction laser scanning step edge detection 3D city models
2015/8/13
In this paper, we describe an algorithm for roof line delineation from LIDAR data which aims at achieving models of a high level of
detail. Roof planes are initially extracted by segmentation based ...
