What is reality capture? It is the process of digitising the physical world by using different measurement technologies such as a laser scanner to create accurate 3D data of a real object in a variety of different software applications and workflows.
After recording the site, an accurate 3D model of the environment is obtained with the data extracted using reality capture techniques.
By capturing an object, building or site, a point cloud is created that reproduces the most accurate representation of reality or “digital reality”.
¿What is reality capture?
Creation of plans with reality capture techniques allows you to create a digital model of any space, property or place with a set of hardwares such as laser scanner, lidar, drone or even iPad or iPhone if you have the right applications. After taking real data with these devices, a three-dimensional (3D) model identical to reality will be obtained.
Thanks to this data collection, we can check and identify if the development of our project is following the initial plans or if we can detect any errors at an early stage of its development.
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 reality capture to a project
To apply reality capture there are several steps to follow:
- 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.
- Select the reality capture tool: There are different hardware and software options, such as laser scanners, drones and even iPhones and iPads.
- Start capturing reality: Collect real-world data through scanning, video or any other chosen technique.
- 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.
- 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.
- 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 can be a valuable technique for many projects. By following all the steps, you can create reality-like 3D models and complete projects more efficiently.
