Automatic Road Vector Extraction for Mobile Mapping Systems
Mobile Mapping Computer Vision Road Geometry Lane Line Automatic Extraction VISAT™
2015/12/9
Land-based mobile mapping systems have yielded an enormous time saving in capturing road networks and their surrounding. However, the manual extraction of the road information from the mobile mapping ...
Orientation and DEM Extraction from ALOS-PRISM Images Using the SRTM-DEM as Ground Control
Three-Line Matching DEM/DTM Georeferencing Orthorectification Accuracy
2015/11/24
This paper presents a methodology of image orientation and DEM extraction from ALOS-PRISM stereopairs without the use of GCPs. It uses the approximate geo-location information derived from the sensor ...

FUSING AIRBORNE LASER SCANNER DATA AND AERIAL IMAGERY FOR THE AUTOMATIC EXTRACTION OF BUILDINGS IN DENSELY BUILT-UP AREAS
Building, Extraction LIDAR
2015/6/1
Using airborne laser scanner data, buildings can be detected automatically, and their roof shapes can be reconstructed. The success
rate of building detection and the level of detail of the resultin...
By means of the progress in photogrammetry; it is now possible to produce the maps of huge areas more quickly and economically
but the production steps are still expensive and time consuming. In rec...
RECONSTRUCTING TREE CROWNS FROM LASER SCANNER DATA FOR FEATURE EXTRACTION
Reconstruction Feature Extraction Laser Scanning
2015/3/25
The objective of this study was to carry out reconstruction of single tree crowns from laser scanner data to use the obtained vector
model for feature extraction. The reconstruction was implemented i...
ACTIVE TESTING AND EDGE ANALYSIS FOR ROAD CENTRELINE EXTRACTION
Edge Analysis Matching Road Extraction Vision Semi-Automation
2015/3/24
As in the foreseeable future a human will be expected to remain as part of the object extraction system, semi-automated road
extraction methods are still important. Following this trend, this paper p...
