point cloud

A point cloud is a collection of data points in space, representing a 3D object, shape, or scene. Each point in the point cloud points represents the X, Y, and Z geometric coordinates of a single point on an underlying sampled surface.


Point clouds are primarily generated through 3D scanning processes, such as those performed by LIDAR or photogrammetry software, capturing detailed measurements of an object’s or area’s surface geometry. When color information is present, the point cloud becomes 4D.



Point clouds can be manipulated with software tools like the Point Cloud Library (PCL). The Motion Picture Experts Group (MPEG) has defined compression and storage formats for point clouds, to create standards for immersive applications.
