Laser scanning has been widely adopted in industrial and architectural environments for data collection and modelling of sites with complex geometry and form. TGM has in-house laser scanning capability.
3D scanning can quickly deliver an extremely high density of measured points – known as a point cloud – over a 360° survey area. The scan density is easily controlled and the instruments can deliver sub-centimetre data at distances of up to 50 metres. The scanner also generates a 360° photo mosaic of the survey. This additional information is then rendered with the point cloud to provide full colour images with real-world 3D coordinates.
Laser scanning measures all objects in the survey area quickly and with minimal human intervention. Key advantages of scanning are:
- Reduced project costs - less time on site means less shutdown time for staff, plant and production lines
- Capturing all data in a survey at one time ensures there are no extra site visits for missed/peripheral data
- Desktop site visits can be undertaken in the office using fly-throughs and rendered images
- Reduced risk and increased safety - quick survey times allows surveyors to stay out of hazardous/risky situations
- Surveyors are not required to use specialist access equipment to gather data in previously inaccessible places: mines, undersides of bridges, towers, chimneys, etc.
3D laser scanning is well suited to a range of industry sectors, in any application that requires high accuracy 3D spatial data.
