3D Laser Mapping

3D laser scanning provides Technics with a wider range of data collection and software output for clients alongside traditional survey technology.

The technology is designed to automatically capture large volumes of 3D survey points – known as point cloud – on the surface of buildings, structures and highways.

Laser scanners provide geospatial surveyors the perfect tool to deliver Survey4BIM for major infrastructure projects.

How does 3D laser scanning work?

Building up a three-dimensional picture of a survey site requires a combination of distance measurements and steering laser beams in a controlled manner. The scanning motion is controlled by a rotary encoder, which guides the beams by adjusting numerous scanning mirrors.

Multiple scans are typically combined into a common reference system – a process referred to as “alignment” or “registration”.

The benefits of 3D laser scanning

The risk of hazards to geospatial surveyors in complex or inaccessible areas is significantly reduced by using laser scanner techniques. With a survey range of up to 300 metres, all areas can be surveyed remotely, with high-speed data collection of up to one million points surveyed per second (accurate to ± 3mm).

3D laser scanners are also beneficial on specific site settings, such as surveying detailed historic and heritage buildings. They can provide comprehensive point cloud data for complex petrochemical sites, tunnelling projects and industrial environments.

How is laser scanning data delivered to clients?

The point cloud data can be exported to drafting software to produce 2D plans and 3D models for topographical floor plans, elevations and sections.

Using various suites of software, Technics can also deliver the following outputs:

  • 3D wire frame line models
  • 3D rendered models
  • TruView
  • Animated visualisations
  • Survey4BIM 3D Revit models, compliant with PAS 1192-2
