Traditional methods of measuring and modeling the surface geometry of large, complex structures or sites that require engineering or survey-grade accuracy are often inaccurate, incomplete or expensive. Inaccurate or incomplete drawings and models often lead to costly construction errors or delays. A portable, auto-scanning laser and PC system that lets users economically obtain accurate, complete, and timely as-built geometry information for large structures and sites. The system can remotely measure natural surfaces up to 100m away at the speed of 800 points per second. With spacing between adjacent points as fine as 1mm, users can capture an extremely high level of detail for large, complex structures and sites. Each 3D point is accurate to 6mm and modeled surfaces are as accurate as 2mm.
