Learn how Reality Capture turns the physical world into precise 3D data with laser scanning technology and its key benefits for construction projects. Reality capture is not only cost-effective, but it also enhances project management by allowing real-time tracking of construction progress.

After recording the site, an accurate 3D model of the environment is obtained with the data extracted using reality capture techniques. The captured data undergoes post-processing to ensure accuracy and usability, making the information invaluable for decision-making in construction and other industries.

By capturing an object, building, or site, a point cloud is created that reproduces the most accurate representation of reality or “digital reality”. This digital model can be further refined using photogrammetry software to ensure an even more detailed representation.

What is reality capture?

The creation of plans using reality capture techniques allows you to produce a digital model of any space, property, or place with hardware such as laser scanners, lidar, drones, or even iPads or iPhones if you have the right applications. After taking real data with these devices, a three-dimensional (3D) model identical to reality will be obtained.

This cost-effective method of data collection enables quick, precise analysis and real-time decision-making throughout the project lifecycle. By leveraging laser scans and other tools, teams can avoid delays and errors, staying aligned with project timelines and budgets.

Benefits of reality capture

This 3D design model can be used as an exact replica of the environment allowing digital simulations to: 

  • improve the efficiency of each project by making decisions based on real facts
  • develop BIM models and As-built drawings with the data obtained
  • help construction by constantly monitoring the physical asset with the design obtained
  • no need to go to the construction site or renovation site 
  • data can be shared with as many people as required
  • increases the speed of the project by eliminating errors at an early stage of the project
  • once the project is complete, assists in asset management

How to apply it to a project

To apply reality capture there are several steps to follow: 

  1. Identify the objective: Before you start, you need to know what you are going to use this technique for. This can range from planning the creation of a building to measuring and modelling machinery.
  2. Select the reality capture tool: There are different hardware and software options, such as laser scanners, drones and even iPhones and iPads. 
  3. Start capturing reality: Collect real-world data through scanning, video or any other chosen technique.
  4. Process the data: Once the data has been collected it must be processed to create the 3D model. This involves the use of specialised software such as C2B Viewer.
  5. Polishing and editing the model: after creating the 3D model you need to go through all the details to ensure it is complete and accurate.
  6. Start using the model in the project: Once the 3D model has been perfected with reality capture technology, all that remains is to put it to use for the main purpose of the project.

In short, reality capture is a valuable, cost-effective technique for many projects. By following all the steps, including post-processing and refining the data, you can create reality-like 3D models and complete projects more efficiently, reducing errors and saving both time and resources.
