AUTOMATIC BUILDING CHANGE DETECTION USING MULTI-TEMPORAL AIRBORNE LiDAR DATA
(Ieee, 2020-01-01)
The automatic detection of building changes is an essential process for urban area monitoring, urban planning, and database update. In this context, 3D information derived from multi-temporal airborne LiDAR scanning is one ...
Automatic Building Boundary Extraction from Airborne LiDAR Data Robust to Density Variation
(2022-01-01)
The alpha-shape ( $\alpha $ -shape) concept, which has its origin in computational geometry, is usually applied in building boundary extraction from airborne LiDAR data. However, the results depend on the appropriate choice ...
The use of Otsu algorithm and multi-temporal airborne LiDAR data to detect building changes in urban space
(Springer, 2021-04-24)
Building change detection techniques are essential for several urban applications. In this context, multi-temporal airborne LiDAR data has been considered an effective alternative since it has some advantages over conventional ...
Regularization of Building Roof Boundaries from Airborne LiDAR Data Using an Iterative CD-Spline
(Mdpi, 2020-06-01)
Building boundaries play an essential role in many applications such as urban planning and production of 3D realistic views. In this context, airborne LiDAR data have been explored for the generation of digital building ...
Comparison between Airborne LiDAR Data and Digital Image Matching for Surface Reconstruction
(2020-03-01)
Nowadays some aerial surveying projects (both manned or not) might integrate imagery and ranging sensor technology, thus allowing both the reconstruction of the surface from airborne laser scanning (ALS) and from the ...
Building change detection from multitemporal airborne LiDAR data: Assessment of different approaches
(2021-10-01)
Building change detection is an important task in urban applications. In the last decades, airborne LiDAR data have been explored, aiming at automatic or semi-automatic detection of different entities or objects. We show ...
Statistical outlier detection method for airborne LiDAR data
(2018-09-20)
Sampling the Earth's surface using airborne LASER scanning (ALS) systems suffers from several factors inherent to the LASER system itself as well as external factors, such as the presence of particles in the atmosphere, ...
Combined effect of pulse density and grid cell size on predicting and mapping aboveground carbon in fast-growing Eucalyptus forest plantation using airborne LiDAR data
(2017-06-07)
Abstract
Background
LiDAR remote sensing is a rapidly evolving technology for quantifying a variety of forest attributes, including aboveground carbon (AGC). Pulse density ...
SYNERGY BETWEEN LiDAR AND IMAGE DATA IN CONTEXT OF BUILDING EXTRACTION
(Copernicus Gesellschaft Mbh, 2014-01-01)
This paper compares the paradigms of LiDAR and aerophotogrammetry in the context of building extraction and briefly discusses a photogrammetric strategy for refining building roof polyhedrons previously extracted from LiDAR ...
