Modelling of inaccessible architectural and structural features can now be surveyed accurately, quickly
and remotely by 3D laser scanning.
|
|
Operation:
- Scanner camera takes an initial snapshot of scene and picture sent to laptop.
- Operator selects desired area of scan and measurement spacing (accuracy).
- Scanner measures with narrow laser pulses across the scene.
- 800 points per second are taken up to a distance of 100m with spacing as fine as 0.5mm.
- Calculations undertaken by ‘time of flight’ method of each pulse from surface to returning to scanner.
- Scan provides a real time 3 dimensional ‘cloud’ which can be interrogated and viewed in 3D.
- Cloud can be output directly to AutoCAD
