3D Laser Scanning

  • 3d laser scanning is a method of spatial data collection from a distance (non-contact).
  • It is based on LiDAR technology (Light Detection And Ranging): detection and positioning of objects by sending and receiving a laser beam.
  • A Laser Scanner is similar to a highly automated topographic Total Station, but is able to measure up to 1 million points per second.
  • Beam is deflected by mirrors to scan the whole object with the required density / resolution.
  • Immediate product: a cloud of measured points (pointcloud) with additional grey-scaled intensity or RGB color information for each point (x,y,z,i) or (x,y,z,r,g,b).
  • It brings reality to desktop.
  • Benefits

    • Extremely fast 3D geometry capture on the field, with concurrent color information recording.
    • Incomparable density / level of detail, especially suitable for complex and irregular objects.
    • Highly accurate and reliable. Accuracy enhanced by oversampling and total geometry capture.
    • Suitable for objects of any size, morphology and complexity.
    • Can be applied for inaccessible / unreachable objects (non-contact method).
    • Produces a wide range of highly reliable & detailed deliverables at a low cost.
    • Fields of application

      • Infrastructure works (highways & roads, bridges, tunnels, dams, etc.)
      • Earthworks / Mining
      • Archaeology / Cultural heritage
      • Industrial (plants, refineries, pylons, cables, equipment, etc)
      • Marine (ships & vessels, engine rooms, pump rooms, decks, equipment, etc)
      • Geological & geotechnical (geological formations, slopes, landslides, etc)
      • Urban planning / City modelling
      • Forensic reconstruction and analysis
      • Visual Effects / Entertainment / Virtual Reality
      • Forestry
      • Products

        • 3D colored and georeferenced pointclouds
        • 360° panoramic images enabled for direct measurement extraction
        • Orthophotos
        • Sections at any position and orientation / contour li
        • Multiple measurements / Volume – cut & fill calculation
        • Geometric shapes – primitives exported in CAD drawings
        • DTMs and 3D meshes
        • Intelligent 3D models (BIM, PDMS, etc)
        • Inspection and comparison analysis results (maps, statistics reports)
        • Videos of 3D pointcloud and models
