laser scan to BIM technology - Steel Construction Detailing Pvt.LTD.ppt

3D survey control markers are set up and co-ordinated on site before the actual scanning process begins. This allows the survey team members to track the information accurately. The actual process of collecting data begins at this stage. For achieving this, 3D laser scanners are used that will relate to the 3D survey control markers. A Point Cloud Data is generated at this stage.
