3D Laser Scanning, also known as terrestrial LIDAR, has been commercially available for several years, providing a detailed, reliable, and accurate solution to many surveying and measurement problems, and has become well adopted for plant and facilities applications where accurate three-dimensional detail of complex facilities is critical for efficient design and construction projects. Terrestrial laser scanners deliver a dense point-wise sampling of an object’s surface. For many applications a surface-like reconstruction is required. The most typical example is the visualization of the scanned data. In many respects, laser scanning follows the same general surveying process as other instruments: data is collected in the field, adjusted to the appropriate coordinate system, and relevant features can be extracted to produce deliverables ranging from topographic maps, coordinate values, 2D or 3D CAD drawings etc. This paper describes typical scanning project from field-to-finish, including common surveying applications.
