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)
