Laser scanning is a method of accurately capturing 3 dimensional as-built data of large areas. The technology has been around for a few years now but its only within the last couple of years that clarity and accuracies are now so advanced that it can be adapted to the oil and gas industry. The Laser Scanner scans the required area at a speed of 120,000 points per second to produce what we call a “point cloud”.
A point cloud is a 3D representation of the area consisting of many millions of points each with x,y,z coordinates which are related back to the local coordinate system. This allows us to establish a coordinate value for any existing point within the area.
Part of the process is to set out a master control system of targets throughout the area to be scanned as multiple instrument set-ups are necessary to ensure a full 3D capture. Each target has a coordinate value based on the establish coordinate system and this allows us to bring all individual set-ups into a common system.
- Method of accurately capturing 3 dimensional as-built data of large areas.
- Innovative capture and modelling of existing building conditions.
- Historical building documentation
- Facility condition visualization
- Physical deviation assessment
- Building Information Model (BIM) development
The fastest scanners record up to one million data points per second. "Virtual Surveying" from the resulting point cloud is often much faster and more economical than conventional field measuring and surveying techniques.
