POLE-LIKE OBJECT EXTRACTION FROM MOBILE LIDAR DATA
LiDAR Point Clouds Local Roughness Graph Cuts based segmentation Pole-like object detection DBSCAN based point clustering
2016/7/5
Object detection and recognition from LiDAR (Light Detection And Ranging) data has been a research topic in the fields of photogrammetry and computer vision. Unlike point clouds collected in well-cont...
GEOMETRIC QUALITY ASSESSMENT OF LIDAR DATA BASED ON SWATH OVERLAP
Lidar Quality Geometry Relative Accuracy
2016/7/4
This paper provides guidelines on quantifying the relative horizontal and vertical errors observed between conjugate features in the overlapping regions of lidar data. The quantification of these erro...
AUTOMATIC MODELLING OF RUBBLE MOUND BREAKWATERS FROM LIDAR DATA
breakwaters water defences LiDAR point cloud 3D modelling
2015/9/21
Rubble mound breakwaters maintenance is critical to the protection of beaches and ports. LiDAR systems provide accurate point clouds from the emerged part of the structure that can be modelled to make...

2015/8/25
A detailed elevation model of the Netherlands has been acquired with the use of Airborne Laser Altimetry and is managed by AHN(Actueel Hoogtebestand Nederland). This elevation model can be used for a ...
OBJECT-BASED CLASSIFICATION OF INTEGRATED MULTISPECTRAL AND LIDAR DATA FOR CHANGE DETECTION AND QUALITY CONTROL IN URBAN AREAS
Change Detection classification quality control multispectral LIDAR
2015/8/3
Digital spatial data are underlying strong temporal changes. The typical approach of updating these changes is to check the data manually by superimposing them on up-to-date orthoimages from aerial or...
Automatic Generation of Building Models from LiDAR Data and the Integration of Aerial Images
3D building models Building extraction Data acquisition LIDAR processing Multi-sensor processing
2015/5/26
In this paper, we present a method for the automated generation of 3D building models from directly observed point clouds generated
by LIDAR. First, building regions are detected automatically. After...
Vehicle Recognition from LiDAR Data.
LIght Detection And Ranging (LIDAR) is a technique, which allows for measuring a huge amount of object point coordinates with
accuracies up to some centimeters in short time. Their conversion into a...
SPATIAL ANALYSIS FOR OUTLIER REMOVAL FROM LIDAR DATA
Spatial analysis Cross-validation LiDAR Outlier detection
2014/12/1
Outlier detection in LiDAR point clouds is a necessary process before the subsequent modelling. So far, many studies have been done in order to remove the outliers from LiDAR data. Some of the existin...
