Abstract
3D Laser Scanning is providing a detailed, reliable, and accurate solution to many surveying and measurement problems, and has become well adopted for complex applications, like plants and other facilities, where accurate threedimensional detail is critical for efficient design and construction projects. Terrestrial laser scanners deliver a dense point-wise sampling of an object’s surface. The most typical example is creation of a 3D As-built model. This paper describes a typical scanning project from field-to-finish . 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, modelled and relevant features are extracted to produce 3D CAD drawings, 2D precise plans and elevation, etc.
