Point Cloud to BIM

Point Cloud to BIM model- basics

Point Cloud scan comprises of a set of a million data points which represent the three-dimensional coordinates of the external surface of a building or an object. This set of data called the point cloud are typically gathered or captured using a 3D laser scanner. Using a variety of surface reconstruction methods facilitated by specialist point cloud processing software, this scan data can reconstruct into a working 3D BIM model which reflects the existing condition of the building or structure.

The process of converting the captured 3d point data into a usable intelligent model is cumbersome, time consuming and expensive. It requires intensive expertise in handling the point cloud as well as rich experience in BIM modeling. The process of converting the point cloud to polygon or triangle mesh models, NURBS surface models, or CAD models through a process commonly referred to as surface reconstruction.

What is Point Cloud?

A point cloud is a set of data points in some coordinate system.

In a three-dimensional coordinate system, these points are usually defined by X, Y, and Z coordinates, and often are intended to represent the external surface of an object.

Point clouds may be created by 3D scanners. These devices measure a large number of points on an object's surface, and often output a point cloud as a data file. The point cloud represents the set of points that the device has measured.
