Study on the Target Feature Extraction from LIDAR Point Clouds
LIDAR Point Cloud Feature Extraction Edge Detection Digital Image Processing
2015/12/8
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...
Feature-Based Registration of Ground-Based LIDAR Point Clouds
Terrestrial LIDAR Multiple features Registration Similarity transformation Simultaneous adjustment
2015/12/8
Complete scene description by using terrestrial LIDAR systems usually requires multiple scans from different stations. Point cloud of each scan is associated to its own coordinate system on a station ...
Building Roof Segmentation and Modeling from LIDAR Point Clouds Using Machine Learning Techniques
LiDAR Building Reconstruction Segmentation Feature Extraction Clustering Data mining
2015/12/4
This paper presents an approach to creating a polyhedral model of building roof from LiDAR point clouds using clustering techniques. A building point cloud is first separated into planar and breakline...
A DATA MANAGEMENT METHOD FOR EFFICIENT SEARCH AND RENDERING OF MULTIPLE LARGE SCALE POINT CLOUDS
Multiple Point Clouds Octree LOD Laser Scanning Data Management Data Search Rendering
2012/9/3
Recently, with the progress of laser scanning technology, it has become possible to scan several environments such as buildings, roads, and cities easily and at a low cost. There are typically three s...
DIMENSIONALITY BASED SCALE SELECTION IN 3D LIDAR POINT CLOUDS
point cloud adaptive neighborhood scale selection multi-scale analysis feature PCA eigenvalues dimensionality
2012/9/3
This papers presents a multi-scale method that computes robust geometric features on lidar point clouds in order to retrieve the optimal neighborhood size for each point. Three dimensionality features...
ANALYSIS OF TWO TRIANGLE-BASED MULTI-SURFACE REGISTRATION ALGORITHMS OF IRREGULAR POINT CLOUDS
LiDAR Surface Registration Iterative Closest Patch (ICPatch) Iterative Closest Projected Point (ICPP)
2012/9/3
The registration of multiple surface point clouds into a common reference frame is a well addressed topic, and the Iterative Closest Point (ICP) is – perhaps – the most used method when registering la...
MIN-CUT BASED SEGMENTATION OF AIRBORNE LIDAR POINT CLOUDS
LIDAR point clouds segmentation eigenvalue analysis graph-cuts min-cut
2012/7/24
Introducing an organization to the unstructured point cloud before extracting information from airborne lidar data is common in many applications. Aggregating the points with similar features into seg...
