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 ...
Photogrammetric refinement of LiDAR-derived building roof contours
(Taylor & Francis Ltd, 2018-01-01)
In this paper, a photogrammetric method is proposed for refining 3D building roof contours extracted from airborne Light Detection And Ranging (LiDAR) data. It is assumed that LiDAR-derived planar faces of roofs are ...
BUILDING ROOF BOUNDARY EXTRACTION FROM LiDAR AND IMAGE DATA BASED ON MARKOV RANDOM FIELD
(Copernicus Gesellschaft Mbh, 2017-01-01)
In this paper a method for automatic extraction of building roof boundaries is proposed, which combines LiDAR data and high-resolution aerial images. The proposed method is based on three steps. In the first step aboveground ...
Three-dimensional building roof boundary extraction using highresolution aerial image and LiDAR data
(2014-01-01)
This paper presents a semiautomatic method for rectilinear building roof boundary extraction, based on the integration of high-resolution aerial image and LiDAR (Light Detection and Ranging) data. The proposed method is ...
Classification of LiDAR data over building roofs using k-means and principal component analysisClassificação de dados LiDAR sobre telhados de edificações usando k-médias e análise de componentes principais
(2018-01-01)
The classification is an important step in the extraction of geometric primitives from LiDAR data. Normally, it is applied for the identification of points sampled on geometric primitives of interest. In the literature ...
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 ...

(Universidade Estadual Paulista (Unesp), 2016-02-29)
Esta dissertação contempla o desenvolvimento de um método que combina os dados LiDAR (Light Detection And Ranging) obtidos por sistema de varredura LASER (Light Amplification by Stimulated Emission of Radiation) e imagens ...
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 ...
Mapping and navigation in an unknown environment using LiDAR for mobile service robots
(2020-08-21)
This paper presents the implementation of mapping, localization, and navigation algorithms for a mobile service robot in an unknown environment. The implementation uses a 3D LiDAR sensor to detect the environment and map ...
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 ...
