Automatically extracting tie points (TPs) on large-size synthetic aperture radar (SAR) images is still challenging because the efficiency and correct ratio of the image matching need to be improved. T...
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 ...
LIDAR is a powerful remote sensing technology for acquisition of 3D information from terrain surface. Algorithms used for LIDAR data in urban area are used mostly to deal with the 3D points cloud an...
Light Detection and Ranging (LIDAR) is a technology used for collecting topographic data. Nowadays there are diverse application areas of LIDAR data that include DTM generation and building extraction...
The automatic detection and 3D modeling of objects at airports is an important issue for the EU FP6 project PEGASE. PEGASE is a feasibility study of a new 24/7 navigation system, which could either re...
Building boundary data are necessary for the real estate industry, 3D city models and many other applications. In this study, a novel approach integrated high resolution imagery and Lidar data is prop...
With the rapid development of remote sensing technology, three dimensional coordinates and intensity information of observation target can be obtained directly from LIDAR system. It is one of the impo...
Over the past years, several filters have been developed to extract bare-Earth points from airborne laser scanner data. we conducted a test to determine the performance of three different filters and ...
The research in the detection and feature extraction of typical objects in urban areas has intensified. In existing detection technologies, it has been shown that the LIDAR technique is very promising...
The goal of this research is to extract and delineate building ground plans from LIDAR data. Our approach consists of three steps: first of all, the raw point cloud has to be classified into terrain p...
LIDAR is an application widely open as an area of study for modelling detailed topographic maps. It is generally used in airborne applications. In this study, the aim is tree extraction from a data ha...
LiDAR has been a major interest of photogrammetry to acquire three dimensional objects. It has shown its promising capabilities in building virtual reality applications, such as virtual campus and vir...
Three dimensional object extraction and recognition (OER) from LIDAR data has been an area of major interest in photogrammetry for quite a long time. However, most of the existing methods for automa...
iring accurate detection and description of buildings is a difficult object recognition problem due to a high complexity of the scene content and the object representation. Since most urban scenes d...
Automated and reliable 3D city model acquisition is an increasing demand. Automatic road extraction from dense urban areas is a challenging issue due to the high complex image scene. From imagery, t...
