All you need to know about 3D Point cloud in 3D laser scanning


If you live in a world of 3D Laser Scanning, then it is unquestionable you are familiar with the term Point Cloud. Red Laser Scanning provides everything you need to know about Point Cloud from what it is, how to work with Point Cloud, its benefits and purpose.

What is Point Cloud?

A Point Cloud is a collection of Data Points obtained by 3D Laser Scanners to create a 3D visualisation and representation of an existing site or object. It is a highly accurate and detailed digital record which processes real and genuine objects and information, which is then converted to an accessible and readable point cloud files. It has revolutionised in the AEC industry and BIM technology as it can be used to create 3D imagery and within other sectors such as 3d Modelling, 3D printing, and VR applications.

Why is this beneficial?

In general, when we think of data being collected in true to life form and having 3D Laser Scanning survey equipment set up on the site to obtain the existing information, it sells as a great gadget and idea. The data is precise and allows no room for errors. All objects are captured in order to create plans and 3D models, no matter how complex the site or building is. Allow extreme accuracy to create as-built drawings, 3D models, and precise elevations, all using point cloud as a background reference.

Working with Point Cloud

In simpler terms, here is the process of creating a scan to model or Scan-to-BIM:

  • The measured surveyor scans building or complete site
  • Point Cloud is then imported to software to create a visualisation of the information collected.
  • When all is viewed, export this data and import into a CAD/BIM system to proceed with elevations for clients.

Point Clouds can be imported in software such as Autodesk Recap, Revit and many more. This allows you to visualise a digital version of the area and take any necessary measurements for your record and to produce for the architect or private client. You may also adjust the level of display of data, remove any unnecessary points such as an animal for example, by clipping and choose the application of colour and its intensity values. The imported Point cloud allows you to manipulate, modify and understand the data. You may grasp anything you need and proceed to export it to produce results for your client.

Importing Point Cloud into BIM/CAD software will guide you through creating detailed and accurate plans with the information collected, allowing a great purpose and advantage of 3D Laser Scanning. The data is turned into 3D surfaces and luckily, with the advanced technology currently, CAD software can manage large amounts of data. In 3D Laser Scanning, it is essential to understand that the Scan-to-BIM all relies on the point cloud, which is why a more in-depth look into the subject is crucial in 3D Laser Scanning.
