A points cloud is an array of points in a system of coordinates. In a system of three-dimensional coordinates, these points are denoted by X, Y, and Z, and are intended to represent the external surfaces of an object. The scans can range from small elements to space cells of a few kilometers.

point-cloud can be created as a product of 3D scanners. These devices measure a large number of points on the surface of the object, and often produce a data file containing the point cloud. Each point has spatial information such as coordinates but can also contain additional information such as: color, temperature and more.

point-cloud, which are the output of 3D scans, are used for many purposes, including creating CAD models for parts manufacturing, metrological control, quality control, and a variety of other applications.

3D laser scanners

A 3D scanner is a device that collects surface information about objects, such as shape, dimensions, temperature and more. After the scanning process it is possible to produce three-dimensional digital models of the same object or produce a 2D program for different uses. The use of 3D scanners is being used more and more by surveyors who find in this technology a solution to classic and complex measurement problems. The construction industry also uses 3D scanners for quality control, and for the documentation of both simple and complex engineering works.
