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.
-
