FACETS : A CLOUDCOMPARE PLUGIN TO EXTRACT GEOLOGICAL PLANES FROM UNSTRUCTURED 3D POINT CLOUDS
geological plane dip and strike dip direction virtual outcrop unstructured 3D point clouds CloudCompare
2016/11/11
Geological planar facets (stratification, fault, joint…) are key features to unravel the tectonic history of rock outcrop or appreciate the stability of a hazardous rock cliff. Measuring their spatial...
DERIVING 3D POINT CLOUDS FROM TERRESTRIAL PHOTOGRAPHS - COMPARISON OF DIFFERENT SENSORS AND SOFTWARE
Close-range photogrammetry structure from motion dense matching software
2016/11/11
Terrestrial photogrammetry nowadays offers a reasonably cheap, intuitive and effective approach to 3D-modelling. However, the important choice, which sensor and which software to use is not straight f...
EVALUATION OF METHODS FOR COREGISTRATION AND FUSION OF RPAS-BASED 3D POINT CLOUDS AND THERMAL INFRARED IMAGES

2016/7/27
This paper discusses the automatic coregistration and fusion of 3d point clouds generated from aerial image sequences and corresponding thermal infrared (TIR) images. Both RGB and TIR images have been...
AUTOMATED MOSAICKING OF MULTIPLE 3D POINT CLOUDS GENERATED FROM A DEPTH CAMERA
Depth Camera Point Cloud Mosaicking Tiepoint Similarity transformation
2016/7/27
In this paper, we propose a method for automated mosaicking of multiple 3D point clouds generated from a depth camera. A depth camera generates depth data by using ToF (Time of Flight) method and inte...
Robust Algorithm for Fitting Sphere to 3D Point Clouds in Terrestrial Laser Scanning
Laser scanning Fitting Terrestrial photogrammetry
2015/12/16
Sphere target is one of the most important tools in terrestrial laser scanning. Different point clouds obtained form different views can
be transformed into the same coordinate system frame by using ...
Improving and Extending the Information on Principal Component Analysis for Local Neighborhoods in 3D Point Clouds
Laser Scanning Point clouds Curvature Approximation
2015/12/16
Principal Component Analysis (PCA) is often utilised in point cloud processing as provides an efficient method to approximate local
point properties through the examination of the local neighbourhood...

The currently existing mobile mapping systems equipped with active 3D sensors allow to acquire the environment with high sampling rates at high vehicle velocities. While providing an effective solutio...
CO-REGISTRATION OF 3D POINT CLOUDS BY USING AN ERRORS-IN-VARIABLES MODEL
Laser scanning point cloud registration matching estimation
2014/4/28
Co-registration of point clouds of partially scanned objects is the first step of the 3D modeling workflow. The aim of co-registration is to merge the overlapping point clouds by estimating the spatia...
EXTRACTING BUILDING FOOTPRINTS FROM 3D POINT CLOUDS USING TERRESTRIAL LASER SCANNING AT STREET LEVEL
3D Point Cloud Hough Transform RANSAC Method
2016/3/1
In this paper, we address the problem of generating building footprints using terrestrial laser scanning from a Mobile Mapping System
(MMS). The MMS constitutes a fast and adapted tool to extract pre...
