About Laser Scanning

3D laser scanning is fast, accurate and safe! 3D laser scanning involves the following elements: The hardware (The Laser Scanner), the software (deliverable of information i.e. Point Cloud, CAD and BIM format), and the knowledge and experience of the operator.

KME Laser Scanning uses LIDAR technology to accurately and efficiently capture 3-Dimensional data regardless of size, surface features or complexity of the structure. The 3D scanner uses line of sight technology and documents anything that is viewable from the point the scanner is placed. The 3D laser scanner captures millions of points and records with extreme accuracy the coordinates and locations of each of these millions of points that represent the existing building conditions. By combining the points collected from the scan (the raw data) our software can merge the multiple scans taken to create a cohesive (“processed”) file known as the “point cloud”. From this file, anyone can view the existing space in the 3D environment and extract measurements. The point clouds can also be imported into CAD or BIM software to assist in developing accurate drawings and 3D models of the existing conditions.

Step 1 – Collecting the Data

The Process of field verifying existing conditions starts by using the 3D laser scanner to capture the information. The scanner is set on a tripod and spins to collect data within the 360-degree view of the scanner. The operator moves the tripod and scanner to multiple locations to increase accuracy and ensure all elements are within view of the scanner and have been collected.

Step 2 – Processing the Data

After we have collected the data on-site, KME Laser Scanning will process the multiple scans into one cohesive 3D “point cloud” model. This point cloud will contain all the information of the areas that were scanned and allow users to extract information such as measurements, 360-degree photos and 3D image model.

Step 3 – Deliverables

Once the files are processed in step 2, the data file has a wealth of information to be used in a variety of aspects. For some of our clients, the processed file is all they require; however, KME Laser Scanning is happy to provide multiple types of deliverables to clients that would require it. From the processed file, we can provide clients with traditional floorplans, elevations, sections, 3-D BIM models, fly throughs and just about any type of information that the client requests.

Applications for Laser Scanning include:

  • Architectural Design
  • As-Builts (plans, elevations, sections)
  • 3D Modeling
  • Commercial real estate
  • Documenting Construction Progress
  • Animated fly-throughs
  • Historical building surveys

Benefits of Laser Scanning:

  • Speed and Efficiency
  • Accuracy
  • Reduced cost
  • Avoid missed or forgotten data
  • Safety
  • Ability to measure complex structure with ease and accuracy.
