What is Point Cloud?

A POINT CLOUD is a set of vertices in a three-dimensional coordinate system. These vertices are usually defined by X, Y, and Z coordinates, and typically are intended to be representative of the external surface of an object.

Point Cloud to Bim are most often created by 3d scanner. These devices measure in an automatic way a large number of points on the surface of an object, and often output a point cloud as a data file. The point cloud represents the set of points that the device has measured.

As the result of a 3D scanning process point clouds are used for many purposes, including to create 3D models for manufactured parts, quality inspection, and a multitude of visualization, animation, rendering.

Usually point clouds themselves are generally not directly usable in most 3D applications, and therefore are usually converted to polygon or triangle mesh models, or CAD/Revit models through a process commonly referred to as surface reconstruction. The point cloud of a manufactured part can be aligned to a CAD/Revit model (or even another point cloud to bim), and compared to check for differences. These differences can be displayed as color maps that give a visual indicator of the deviation between the manufactured part and the CAD model. Geometric dimensions and tolerance can also be extracted directly from the point cloud.
