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...
PAIRWISE-SVM FOR ON-BOARD URBAN ROAD LIDAR CLASSIFICATION
LiDAR on-board classifiaction SVM MRF
2016/7/4
The common method of LiDAR classifications is Markov random fields (MRF). Based on construction of MRF energy function, spectral and directional features are extracted for on-board urban point clouds....
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...
