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 ...
ROAD REGION DETECTION IN URBAN AREAS COMBINING HIGH-RESOLUTION RGB IMAGE AND LASER SCANNING DATA IN A CLASSIFICATION FRAMEWORK
(Copernicus Gesellschaft Mbh, 2013-01-01)
This paper addresses the problem of road region detection in urban areas using an image classification approach. In order to minimize the spectral superposition of the road (asphalt) class with other classes, the Artificial ...

Comparison between two radiometric calibration methods applied to UAV multispectral images
(2020-01-01)
There are many advantages of using unmanned aerial vehicles (UAVs) in remote sensing but when using radiometrically corrected multispectral images. This study focuses on two techniques of obtain a multispectral orthomosaic ...
Photogrammetric refinement of laser-based building roof contours
(2013-08-15)
In this paper a photogrammetric method is proposed for refining 3D building roof contours extracted from airborne laser scanning data. It is assumed that laser-derived planar faces of roofs are potentially accurate, while ...
