Digital Scanning Group delivers accurate point cloud surveys using the latest laser scanning technology. Our surveys provide sub-millimetre accuracy for as-built documentation, renovation planning and heritage preservation across London and the UK.
A point cloud survey uses 3D laser scanning technology to capture millions of precise spatial measurements of a building or structure. The result is a dense cloud of data points that represents every visible surface in accurate 3D. This data can be used for measurement, modelling, analysis and visualisation.
Laser scanning uses a rotating laser to directly measure distances to surrounding surfaces, producing highly accurate point cloud data regardless of lighting conditions. Photogrammetry uses overlapping photographs and software algorithms to reconstruct 3D geometry. Laser scanning is generally more accurate and reliable for interior surveys, while photogrammetry can be more efficient for large exterior areas or facades.
Using survey-grade Leica and FARO laser scanners, our point cloud surveys achieve accuracy of 2mm or better at typical working ranges. For projects requiring higher precision, we can deploy targets and control networks to achieve sub-millimetre accuracy across large sites.
Standard deliverables include registered and coloured point cloud datasets in industry-standard formats (RCP, E57, LAS). We also offer 2D CAD drawings, 3D Revit BIM models, floor plans, sections and elevations. Deliverables are tailored to your project requirements.
A single room can be scanned in 15-20 minutes per scan position. A typical commercial floor of 500 sqm requires 15-25 scan positions and can be completed in half a day. Larger buildings or multi-storey surveys are typically completed within 1-3 days depending on complexity and access arrangements.
Yes. Point cloud data is the foundation for our Scan to BIM service. We use the registered point cloud as a reference to model the building in Autodesk Revit at the Level of Development (LOD) your project requires. This is the most common workflow for renovation and refurbishment projects that require accurate as-built BIM models.
