Learn all there is to know about 3D laser scanning

What is 3D laser scanning? 

Firstly, 3D scanning is used widely in architecture and construction. It is a highly accurate method to capture the details of an existing building or construction site. The laser scanning can help designers visualize their designs by using real building data as a foundation. In addition, without physically touching what is being measured, 3D laser scanning creates clear and precise digital records of existing conditions.   

How does 3d scanning work?  

So, the laser projects a line of laser light onto the surface. While 2 sensor cameras, continuously record the changing distance and shape of the laser in 3 dimensions as it goes along the object.    

What is the scanner used for?  

Some of the common uses are: 

  • Prefabrication  
  • Collecting geospatial data 
  • Virtual design and construction  
  • 2D & 3D laser map of a building 
  • Laser scanning for facility coordination  
  • Design engineering for facility upgrades or expansions 
  • Architectural documentation or historical preservation 
  • As built survey, reality capture or existing conditions survey 
  • Calculating volumes, deformation analysis and overhead clearances 

 
Functionality –   

The purpose of a 3D scanner is to create a 3d model. However, the 3D models often consist of a point cloud of geometric samples on the surface of the design.   

Furthermore, the scanner shares similar traits with a camera, and like cameras, they can only collect information about surfaces that are not obscured. While cameras collect colour information about surfaces within their field of view, a 3D scanner collects distance information about surfaces.   

However, a single scan will not produce a complete model of the building. You will need to do multiple scans, in different directions to get the information of all sides of the project.  

Benefits of 3D scanning –  

  • Fast – a laser scanner can capture up to a million 3D data points per second. This provides an incredibly accurate detail of every aspect of your project.  
  • Accurate – because of how many data points are collected laser scanning is the most accurate form of measurement available. Whereas, measurements acquired by hand held devices and tape measures are subject to errors.  
  • Safety – 3D scanning can acquire measurements in hard to reach or hazardous locations, keeping workers safe.  
  • Captures every detail – A 3D scan will capture extra data. Meaning you wouldn’t need to return to the project if you have any unanswered questions.

The advanced Leica 3D scanner in architecture

2nd February 20220

Here at Pro Arkitects we are using a state-of-the-art 3D Lazer scanner, to get the technical measurements of your property. If you are interested and want to find out more about the scanner and what it does, read on.     

What is a Leica 3D scanner?  

Leica 3D laser scanning software suite sets the industry standard to capture, visualise, extract, analyse, share, and represent point cloud data. They deliver outstanding range, speed, and the highest quality of 3D data.  

What is 3D scanning?   

3D scanning is used widely in architecture and construction. It is a highly accurate method to capture the details of an existing building or construction site. Laser scanning can help designers visualize their designs by using real building data as a foundation. 

How does 3D scanning work? 

Specialised software drives the laser probe above the surface of the object. The laser probe projects a line of laser light, onto the surface while 2 sensor cameras record the changing distance and shape as it sweeps along the object.  

At pro arkitects we want to provide the best service that we can, and we achieve this by using the Leica scanner. Our drawings have become so much more detailed because the scanner captures accurate measurements and scans.  

Pros and cons of 3D scanning –   

Pros –   

  • Between 1 and 2 million points of measurable data is collected per second.   
  • It takes a fraction of the time compared to measuring by hand.   
  • You will get the drawings quicker.   
  • Helps design teams to save money.   
  • Increases professionalism of your project.  
  • Gives architects confidence in their work.  

Cons –   

  • The laser scanner is very expensive   
  • Errors could happen while the scanner is scanning   

How much does a Leica scanner cost? 

Laser scanners can be quite expensive. However, the level of detail and advanced technology they use. There are plenty of great entry-level options for a couple of thousands of pounds. Although, the mid-range 3D scanners tend to cost between £7,400 – £29,500. The very high-end scanners can reach up and over £737,000.
