SUB-PIXEL EDGE LOCALIZATION BASED ON LASER WAVEFORM ANALYSIS
Urban Analysis Laser scanning LIDAR Edge Sub-pixel precision
2015/8/13
Laser range data is of high interest in photogrammetry. However, compared to passive imagery, it usually has a lower image
resolution, making geometry extraction and modeling challenging. A method t...
OPTIMIZATION OF THE SCANNING ANGLE FOR COUNTRYWIDE LASER SCANNING
Digital Terrain Model DTM airborne laser scanning ALS countrywide quality
2015/8/13
Countrywide collection of laser scanning, mainly due to DTM derivation, is becoming increasingly attractive. Since Finland is a
large country, optimization of scanning parameters is important from th...
MARKER-FREE REGISTRATION OF TERRESTRIAL LASER SCANS USING THE NORMAL DISTRIBUTION TRANSFORM
LIDAR Laser scanning Terrestrial Registration Matching
2015/8/7
The registration of scan data often uses special markers which are placed in the scene. This leads to a reliable registration
but the method is not very efficient. Therefore, we search for a re...
STRATEGY FOR THE EXTRACTION OF 3D ARCHITECTURAL OBJECTS FROM LASER AND IMAGE DATA ACQUIRED FROM THE SAME VIEWPOINT
Laser scanner image data terrestrial surveying 3D reconstruction semi-automation data fusion
2015/8/7
This paper presents a general strategy for 3D reconstruction of complex architectural scenes. This approach makes use of both laser
data (range and retro-diffusion) and image data, and of their great...
URBAN MODELING BASED ON SEGMENTATION AND REGULARIZATION OF AIRBORNE LIDAR POINT CLOUDS
idar Building reconstruction Urban area modelling
2015/6/1
This paper presents an approach to process raw lidar 3-D point clouds over urban area and extract terrain, buildings and other urban
features. In the initial step, “non-ground points” are separated ...
REGISTRATION OF AIRBORNE LASER DATA WITH ONE AERIAL IMAGE
Airborne Laser Scanner Data Aerial Image,
2015/6/1
At present, the calibration of airborne laser scanner data relies on the estimation of the position and attitude of the aircraft during the
acquisition using GPS and INS systems, but also on the esti...
EPIPOLAR GEOMETRY OF LINEAR ARRAY SCANNERS MOVING WITH CONSTANT VELOCITY AND CONSTANT ATTITUDE
Photogrammetry Analysis Direct
2015/6/1
Image resampling according to epipolar geometry is a prerequisite for a variety of photogrammetric tasks such as image matching,
DEM and ortho-photo generation, aerial triangulation, map compilation...
IMAGE CLASSIFICATION WITH A REGION BASED APPROACH IN HIGH SPATIAL RESOLUTION IMAGERY
Image segments classification object-oriented approach
2015/6/1
A number of studies have been carried out to find an appropriate spatial resolution to which to aggregate data in order
to reduce the variation within an object, and minimize the classification erro...
This article describes a new photogrammetric 3-D measurement system for flat objects like plywood boards. 3-D measurement is
needed to get true dimensions of the object along its possibly curved sur...
