Unlike CloudViewer, it can also draw interesting point cloud information such as normals, principal curvatures and geometries. It can display multiple point clouds side-by-side so they can be easily compared, or draw various primitive shapes (e.g., cylinders, spheres, lines, polygons, etc.) either from sets of points or from parametric equations.
Point set registration is the process of aligning two point sets. Here, the blue fish is being registered to the red fish. In computer vision, pattern recognition, and robotics, point-set registration, also known as point-cloud registration or scan matching, is the process of finding a spatial transformation (e.g., scaling, rotation and translation) that aligns two point clouds.
Point clouds are often aligned with 3D models or with other point clouds, a process termed point set registration. The Iterative closest point (ICP) algorithm can be used to align two point clouds that have an overlap between them, and are separated by a rigid transform . [ 5 ]
CloudCompare an open source point and model processing tool that includes an implementation of the ICP algorithm. Released under the GNU General Public License. PCL (Point Cloud Library) is an open-source framework for n-dimensional point clouds and 3D geometry processing. It includes several variants of the ICP algorithm.
Voxel is an image of a three-dimensional space region limited by given sizes, which has its own nodal point coordinates in an accepted coordinate system, its own form, its own state parameter that indicates its belonging to some modeled object, and has properties of modeled region. This definition has the following advantage.
LIDAR scanning describes a survey method that uses laser-sampled points densely packed to scan static objects into a point cloud. This requires physical scanners and produces enormous amounts of data. In 2007 the band Radiohead used it extensively to create a music video for "House of Cards", capturing point cloud performances of the singer's ...
Mobile cloud computing is the combination of cloud computing and mobile computing, in which mobile devices perform computation offloading to balance the power of the cloud for accelerating application execution and saving energy consumption. In this computation offloading, a mobile device migrates part of its computing to the cloud.
The thinning operation entails using some predefined rule to remove points from a point process to form a new point process .These thinning rules may be deterministic, that is, not random, which is the case for one of the simplest rules known as -thinning: [1] each point of is independently removed (or kept) with some probability (or ).
