Definition
Reality capture is the process of recording the physical world in accurate digital form, usually as 3D data. Using tools like laser scanners, drones, and cameras, it captures the exact shape, size, and appearance of real places and objects.
The result is a detailed digital record, such as a point cloud or 3D model, that faithfully represents reality. Teams can then measure, analyse, and work from this data long after leaving the site.
In simple terms, reality capture creates a precise digital copy of the real world, so a place or object can be explored and measured on screen.
How It Works
Reality capture starts with collecting data using one or more methods. Laser scanning measures millions of points directly, photogrammetry reconstructs 3D geometry from overlapping photos, and drones capture sites from above. These techniques are often combined for complete coverage.
The raw data is then processed, cleaned, and aligned into a unified dataset such as a point cloud or textured model. This digital record can feed into BIM, digital twins, and analysis tools, becoming a reliable foundation for design, construction, and management.
Applications
Reality capture is used in construction, architecture, heritage, facility management, and infrastructure. It documents as-built conditions, supports renovation and scan-to-BIM, preserves historic sites, tracks construction progress, and builds the accurate base data behind digital twins.
Benefits
- Accurate digital record of real-world conditions.
- Fewer site visits thanks to reusable data.
- Strong foundation for BIM and digital twins.

Frequently Asked Questions
What is reality capture used for?
It is used to document existing conditions, support renovation and BIM, preserve heritage sites, and build the data behind digital twins.
What methods are used in reality capture?
Common methods include laser scanning, photogrammetry, and drone mapping, often combined for complete coverage of a site.
What is the output of reality capture?
The output is usually a point cloud or 3D model that accurately represents the captured place or object.
How is reality capture related to digital twins?
Reality capture provides the accurate real-world data that a digital twin is built on and kept up to date with.
