3D laser Scanning, also known as LIDAR (Light Detection And Ranging) utilises a very rapid laser beam to scan its environment. This generates an enormous number of points in the form of a point cloud. Objects can then be modelled or spatial data can be extracted from the point cloud.
3D laser Scanning is perhaps the most exciting and rapidly developing method of collecting survey data. Dense point clouds comprising of literally millions of co-ordinated points are created within minutes. We are now able to capture data at a rate of up to 1 million points per second.
SEP collect somewhere in the region of 300 billion (although they havenít been fully counted) full colour, 3D points per year which can all be related to OS. With so many points being collected in such a short space of time, the duration a survey team needs to remain on site can be dramatically reduced.
With the Laser Scanner picking up everything that it sees within its 360 degree window any level of detail can been added to drawings. Should further information need to be included at a later stage, perhaps when demolition has already taken place, it is just a case of adding the new information to the drawing, without costly revisits to site being required.
The advantages of laser scanning to traditional methods consist of the reduction of site measuring time, far greater levels of detail being produced, the elimination of return visits to site and the fact that you can remotely measure objects, which is excellent for difficult and dangerous areas.
Laser Scanning applications include: Measured Building Surveys, Elevations, Monitoring, Architectural Design, Forensic and crime scene analysis, Mining & Quarrying, Heritage projects, Reverse engineering, 3D Modelling and Film & Animations.
SEP deliverables include: 2D & 3D DWG's/DXF, 3D Models, Visualisations, Video Fly-through and Point Cloud Export.
