3D Laser Scanning
Terrestrial 3D Laser Scanning.
Whether you’re designing a modification to a complex refinery piping system, surveying a site or documenting a historic building, you need reliable, fast & useful measurements for your project needs.
Typical Application Areas
3D laser scanners can be found in various applications like documentation of:
• industrial facilities
• infrastructure
• mining
• buildings and architecture
• cultural heritage and archaeology
• forensic sites
• prototypes
• virtual reality objects
• accidents
The “next-generation” scanners significantly reduce field costs and increases phase-based data quality for many types of as-built and site surveys where users want to take advantage of ultra-high speed, phase-based laser scanning. 3D laser scanners are the perfect instrument to capture arbitrary laminar surfaces.
The useful range of phase-based scanning has been stretched and data quality improved. This provides productivity benefits, while also expanding the types of projects where phase-based scanning can be used, such as capturing multi-story building facades.

Propane Cooler - Raw point cloud
This vessel was located adjacent to a pipe rack which was the focus of the laser scanning exercise, and was collected as overscan. The image above is the raw point cloud before any modelling has been undertaken. The density of data can be seen in the lettering midway along the main body, and the individual bolts on the front flange.
Solidification of point cloud
The point cloud is modelled as a series of contiguous solids; this transforms the data from a dense set of individual points into a single object. At this stage the model now has all the characteristics of a CAD solid (dimensions, surface area, volume etc.).
Cross-Section Production
There are multitudinous ways of presenting the data derived from scanning. Naturally 3D presentations are an obvious choices due to the 3D nature of the scan cloud. This can include, for example 3D solids as described above.
Additionally, traditional 2D representations are often found to be of benefit due to the simplicity of working with this type of represeentation. An example is cross-sectional data, derived directly from the point cloud. These cross sections can be taken through any appropriate plane and at any required intervals, giving dimensional information which can be directly compared with design.

3D CAD is fast becoming a standard for engineering design and review, as 3D literacy amongst professionals increases, and the software tools become easier to interact with. A 3D as-built model, such as the one above (click on the link to manipulate the 3D pdf), is information dense, and provides an unbeatable way of communicating and interacting between engineers, designers, and clients.
